Leema Acoustics Tucana II Anniversary Integrated Amplifier

Audio T Verdict

The Leema Acoustics Tucana II Anniversary is a powerful and exceptionally controlled integrated amplifier that can form the heart of a genuinely ambitious music system.

Its 150W-per-channel output is supported by high-current dual-mono amplification and three separate power transformers, giving it the authority to control demanding loudspeakers without sacrificing detail, timing or musical expression.

The Anniversary Edition upgrades the already accomplished Tucana II with double-weight copper circuit boards, Nichicon MUSE capacitors and Leema Reference-grade internal speaker wiring. The result is a cleaner and more revealing version of a long-established Audio T favourite.

With balanced and unbalanced analogue inputs, headphone output, variable pre-out, AV Direct and LIPS system control, the Tucana II Anniversary combines serious performance with the flexibility required for both simple stereo systems and more advanced installations.

Anniversary Edition Upgrades

The Tucana II Anniversary was created to celebrate ten years of Leema’s original Tucana integrated amplifier.

Rather than changing the established amplifier concept completely, Leema concentrated on improving key components and lowering resistance throughout the internal signal and power paths.

Anniversary Edition upgrades include:

  • Double-weight copper printed circuit boards
  • Reduced circuit-board impedance
  • Nichicon MUSE Series audio capacitors
  • Leema Reference-grade internal speaker cable
  • Hand-selected power transistors
  • Noratel low-noise transformers
  • Chrome-plated Leema Delta front-panel logo
  • Individual assembly and test documentation
  • Updated Focus remote control

These changes are intended to improve current delivery, reduce noise and reveal more musical information while preserving the character and control for which the Tucana has become known.

Double-Weight Copper Circuit Boards

The Anniversary Edition uses printed circuit boards with twice the normal copper weight.

Leema states that this halves the impedance of the circuit-board tracks, providing a lower-resistance route between the amplifier’s internal components.

The potential benefits include:

  • Improved current delivery
  • Reduced electrical resistance
  • Lower power loss within the circuit
  • Stronger dynamic performance
  • Greater control during demanding musical passages

Nichicon MUSE Series Capacitors

Key capacitors are upgraded to selected Nichicon MUSE Series components.

These are designed specifically for audio circuitry and are used where Leema determined that they could improve the amplifier’s performance.

The upgrade is intended to support:

  • Lower noise
  • Improved low-level detail
  • Cleaner signal handling
  • Greater tonal clarity
  • More precise musical dynamics

Leema Reference-Grade Internal Wiring

The internal connection between the amplifier boards and loudspeaker terminals uses Leema’s own Reference-grade speaker cable.

This replaces the conventional internal speaker wiring used in the standard Tucana II and provides a high-quality final connection between the output stages and rear terminals.

150W Per Channel into 8 Ohms

The Tucana II Anniversary delivers 150W RMS per channel into an 8-ohm loudspeaker load.

Its output increases substantially as the loudspeaker impedance falls:

  • 150W RMS per channel into 8 ohms
  • 290W RMS per channel into 4 ohms
  • 320W RMS per channel into 2 ohms under the manufacturer’s published test conditions

The increasing output into lower impedances demonstrates that the Tucana II Anniversary has been designed to provide substantial current rather than producing its headline power only into an easy loudspeaker load.

This makes it suitable for a wide range of high-quality standmount and floorstanding loudspeakers.

Confirm Particularly Difficult Loudspeaker Loads

A published output measurement into 2 ohms does not mean that every loudspeaker with a severe impedance curve will automatically be suitable.

Nominal impedance, minimum impedance, electrical phase, sensitivity, room size and normal listening level should all be considered before choosing a speaker partner.

High-Current Loudspeaker Control

Power output alone does not determine how effectively an amplifier will control a loudspeaker.

The Tucana II Anniversary’s substantial power supplies and parallel output devices are designed to maintain current delivery when the connected loudspeaker becomes electrically demanding.

This can contribute to:

  • Firm and clearly defined bass
  • Strong rhythmic timing
  • Clean musical dynamics
  • Reduced compression at higher levels
  • Stable performance with lower-impedance loads
  • Greater control of large bass drivers

Dual-Mono Amplifier Construction

The left and right power-amplifier channels are electrically separated and have their own power transformers, rectifiers and reservoir capacitors.

A third transformer supplies the control electronics, helping isolate the microprocessor and operating system from the audio power stages.

This dual-mono arrangement supports:

  • Strong left and right channel separation
  • A stable central image
  • Clear placement of voices and instruments
  • Consistent power delivery to both loudspeakers
  • Reduced interaction between the two channels
  • Convincing soundstage width and depth

Three Toroidal Power Transformers

The Tucana II platform uses three separate toroidal transformers.

One transformer supplies each power-amplifier channel, while the third is dedicated to the control circuitry.

Separating these power supplies helps prevent the microprocessor and front-panel control system from sharing the same transformer as the sensitive audio electronics.

Six Hand-Selected Output Transistors Per Channel

Each power-amplifier channel uses six hand-selected output transistors.

Using several carefully matched devices in parallel provides:

  • Greater current capability
  • Lower output impedance
  • Reduced electrical and thermal stress per transistor
  • Improved reliability
  • Lower distortion into demanding loads
  • A wider safe operating area

The output devices work with Leema’s thermal-management design to maintain stable performance as listening levels and operating temperatures change.

5Hz to 100kHz Frequency Response

Leema specifies a frequency response from 5Hz to 100kHz within a +0/-3dB tolerance.

This bandwidth extends considerably beyond the conventional audible range and helps preserve controlled phase behaviour through the upper frequencies.

The final system bandwidth will also depend on the source component and connected loudspeakers.

Low Noise and Distortion

The Tucana II Anniversary is designed to combine substantial output power with low noise and distortion.

Leema publishes:

  • 0.004% total harmonic distortion at 90% of rated output
  • A noise floor below -100dB

Low distortion helps preserve instrumental texture and tonal character, while the low noise floor allows quieter musical information to remain clear.

Precision Source Selection and Volume Control

Source selection is handled through relay switching controlled by the amplifier’s internal microprocessor.

The volume system uses precision electronic attenuation rather than a conventional motorised potentiometer.

This approach is designed to provide:

  • Accurate left and right channel tracking
  • Repeatable volume settings
  • Reduced wear compared with a mechanical volume track
  • Remote operation without a motorised control
  • A clear visual indication through the front LED ring

Individual Input Gain Adjustment

The gain of each source input can be adjusted independently over an approximate range of plus or minus 10dB.

This is useful because different sources can have significantly different output levels.

Correct input-gain adjustment can help:

  • Reduce sudden changes when switching sources
  • Match a quiet tuner or portable player to a CD player
  • Make source comparisons more meaningful
  • Improve the useful range of the main volume control
  • Provide more consistent everyday operation

The selected gain setting is stored and applied whenever that input is used again.

Balance Adjustment

The balance control allows the relative level of the left and right channels to be adjusted.

This can be useful where:

  • The listening position is not perfectly central
  • The room is acoustically asymmetrical
  • One loudspeaker is closer to a boundary
  • A recording has an off-centre image
  • Small hearing differences need to be accommodated

The balance setting also affects the variable pre-amplifier output.

Balanced XLR Analogue Input

One stereo balanced input is provided through separate left and right XLR sockets.

A balanced connection can be particularly useful where:

  • The source provides genuine balanced outputs
  • Longer interconnects are required
  • Signal cables must run close to mains cables
  • Resistance to common electrical interference is important
  • The wider system already uses balanced connections

Suitable balanced sources include the Leema Elements CD Player and Leema Elements Streamer.

Six Stereo RCA Inputs

Six stereo unbalanced RCA inputs provide extensive connectivity for conventional line-level analogue sources.

Suitable equipment may include:

  • CD players
  • Music streamers
  • External digital-to-analogue converters
  • Tuners
  • Phono stages
  • Televisions with suitable analogue outputs
  • Portable players
  • Multichannel sources with analogue outputs

A Phono Stage Is Not Built In

The Tucana II Anniversary’s RCA inputs are line level and cannot accept the output of a conventional turntable cartridge directly.

A suitable external phono stage is required unless the turntable already provides a line-level output.

Front-Panel 3.5mm Input

A 3.5mm stereo input is positioned on the front panel for convenient connection of a temporary analogue source.

It can be used with suitable outputs from:

  • Portable music players
  • Phones or tablets using an appropriate adapter
  • Laptop computers
  • Personal recorders
  • Other temporary line-level equipment

The front connection repeats the corresponding rear input, so the front and rear versions should not be used simultaneously.

Dedicated Tape Loop

A tape input and fixed-level tape output are provided for compatible recording equipment.

The tape connections may be used with:

  • Cassette decks
  • Reel-to-reel recorders
  • CD recorders
  • Analogue-to-digital recorders
  • Selected external processors

The tape output receives the selected source but does not follow the main volume control.

The Tape Output Is Fixed Level

Do not connect the tape output directly to a power amplifier, active loudspeaker or any other input that requires volume-controlled operation.

Dedicated AV Direct Input

AV Direct allows the Tucana II Anniversary to power the front left and right loudspeakers within a compatible home cinema system.

The front-channel pre-amplifier outputs from an AV receiver or surround processor are connected to the dedicated AV Direct input.

When AV Direct is selected, the Tucana II Anniversary raises its volume gradually towards a predetermined operating point. Manual volume adjustment remains available as an additional safety feature.

AV Direct Requires an Externally Controlled Source

Only connect an AV receiver or surround processor that provides safe and reliable variable volume control.

A fixed-output CD player, streamer, DAC or phono stage must not be connected to AV Direct, as an unexpectedly high playback level could result.

Variable RCA Pre-Amplifier Output

A stereo RCA pre-out follows the selected source, balance setting and main volume control.

It can be used for:

  • Connecting an active subwoofer
  • Adding an external power amplifier
  • Passive bi-amplification
  • Feeding compatible bass-management equipment
  • Expanding the system at a later stage

Connecting an Active Subwoofer

The variable pre-out can supply a compatible active subwoofer.

The subwoofer should provide suitable controls for:

  • Low-pass crossover frequency
  • Output level
  • Phase
  • Automatic or triggered power operation where required

The crossover and output level should be adjusted so that the subwoofer extends the main loudspeakers without producing excessive overlap or an obvious separate source of bass.

Adding a Hydra II for Bi-Amplification

The pre-out can feed a Leema Acoustics Hydra II Power Amplifier for passive bi-amplification.

A typical arrangement uses:

  • The Tucana II Anniversary to drive one section of each loudspeaker
  • The Hydra II to drive the other section
  • The Tucana’s pre-out to feed the Hydra II

Remove the Loudspeaker Terminal Links

When passive bi-amplifying, the links between the loudspeaker’s high-frequency and low-frequency terminals must be removed.

Leaving the links fitted can connect two amplifier outputs together and cause serious damage. Audio T setup is strongly recommended.

Front-Panel Headphone Output

A dedicated 3.5mm headphone socket is fitted to the front panel for private listening.

This allows any connected analogue source to be enjoyed without adding a separate headphone amplifier.

Compatibility will depend on the headphones’:

  • Impedance
  • Sensitivity
  • Required listening level
  • Cable termination
  • Electrical demands

Particularly insensitive or specialist headphone designs should be checked for compatibility before purchase.

Single Stereo Loudspeaker Output

The Tucana II Anniversary provides one positive and one negative output terminal for each stereo channel.

It is intended to drive one conventional stereo loudspeaker pair rather than independently switched A and B speaker zones.

The shrouded terminals accept 4mm banana plugs.

Loudspeaker Connection Safety

The red amplifier terminal must connect to the positive terminal on the loudspeaker, while the black amplifier terminal must connect to the negative terminal.

Before switching on:

  • Confirm every connection is secure
  • Check left and right channel allocation
  • Check positive and negative polarity
  • Ensure no exposed conductor can touch another terminal
  • Confirm the speaker cables are not damaged

The Amplifier Has No Conventional Output Short-Circuit Protection

Leema deliberately avoids placing conventional protection circuitry in the output signal path.

Shorting the loudspeaker terminals while the amplifier is powered can cause internal fuse failure or more serious damage. Always switch off and disconnect the amplifier from mains power before changing speaker cables.

Thermal Protection

The Tucana II Anniversary monitors its operating temperature.

If the amplifier becomes excessively hot, it enters standby and displays a heat warning until it has cooled sufficiently.

To maintain reliable operation:

  • Allow clear ventilation around the chassis
  • Do not cover the side heatsinks
  • Do not stack another component directly on top
  • Keep the amplifier away from radiators and direct sunlight
  • Use suitable loudspeakers and secure cable connections

Leema Intelligent Protocol System

LIPS stands for Leema Intelligent Protocol System.

It allows compatible Leema components to exchange operating commands and work as a coordinated system.

Depending on the connected products, LIPS can communicate:

  • Power commands
  • Source selection
  • Volume information
  • Balance information
  • System-status information
  • Home-automation commands through a compatible interface

The Tucana II Anniversary can operate as either a LIPS master or slave.

Automatic Leema System Operation

Compatible linked components can respond together when a source is selected.

For example, selecting a connected Leema CD player can:

  • Switch the source component on
  • Select the appropriate Tucana input
  • Prepare other compatible Leema components
  • Allow several units to respond to one remote control

This provides the flexibility of separate components with some of the convenience of an integrated system.

Focus Remote Control

The Anniversary Edition is supplied with Leema’s Focus remote control.

It provides convenient access to:

  • Power and standby
  • Source selection
  • Volume adjustment
  • Mute
  • Compatible LIPS-connected Leema products

LED Volume Display

A ring of front-panel LEDs provides a clear visual indication of the selected volume level.

The LED ring is also used while adjusting input gain and channel balance.

The display can be read from the listening position and does not rely on a conventional numerical screen.

Input-Change Volume Protection

The amplifier briefly mutes when changing inputs and restores playback at a low level.

This helps protect the loudspeakers and listener from clicks or unexpected differences between source levels.

The gradual volume rise can be interrupted immediately using the front volume control or remote handset.

No Built-In DAC or Network Streamer

The Tucana II Anniversary is a dedicated analogue integrated amplifier.

It does not include:

  • A digital-to-analogue converter
  • Optical or coaxial digital inputs
  • USB computer audio
  • HDMI connectivity
  • Bluetooth
  • Wi-Fi or Ethernet
  • Network music streaming

Digital and network sources should be connected through their analogue outputs or through a separate DAC.

Connecting the Leema Stream IV

The Leema Acoustics Stream IV combines CD playback and network streaming within one full-width digital source.

Its stereo RCA analogue output can be connected to any suitable Tucana II Anniversary line input.

The Stream IV then performs digital conversion, while the Tucana controls source gain, listening volume and loudspeaker drive.

Connecting the Elements CD Player

The Leema Acoustics Elements CD Player can connect through either balanced XLR or unbalanced RCA.

Balanced XLR provides a fully balanced connection between the source and amplifier, while RCA may be preferable where the balanced input is required for another component.

Connecting the Elements Streamer

The Leema Acoustics Elements Streamer also provides balanced XLR and unbalanced RCA outputs.

It adds network music playback, compatible online services and USB media support without requiring a separate external DAC.

Connecting a Turntable

A conventional turntable requires a suitable phono stage between its cartridge and one of the Tucana’s line-level inputs.

The phono stage must be matched to the cartridge type:

  • Moving magnet
  • Moving coil
  • High-output moving coil
  • Moving iron where applicable

Browse phono stages available from Audio T to compare suitable options.
