Audio T Verdict
The Naim Burndy Cable Set for NAPS 555 is a matched pair of dedicated multi-pin leads for compatible Naim source components that use separate analogue and digital power connections from a 555 PS or 555 PS DR.
The set contains two different cables, not two interchangeable copies: one is assigned to the source's analogue supply section and the other to its digital section. Both must be connected to the correctly marked sockets when the partner product requires the twin-cable arrangement.
This is not the single S-XPS Burndy used by products such as the NDX 2, and it is not the separate New Classic cable set for the NSS 333 or NSC 222. Confirm the exact source, power supply and cable part number before ordering.
Naim Burndy Cable Set for NAPS 555
This genuine Naim twin Burndy set connects a compatible dual-input source component to the NAPS 555, also known as the 555 PS or 555 PS DR power supply.
Naim lists the set under part number 00-010-0108. It provides one analogue Burndy lead and one digital Burndy lead, each using keyed multi-pin connectors with locking collars.

- Connector shape alone does not prove compatibility
Two Distinct Cables in One Set
The set contains an analogue Burndy lead and a digital Burndy lead. Their internal wiring and connector keying correspond to different supply sections, so each cable must follow the analogue or digital markings on the source and power supply.
They should remain identified as a pair and must not be swapped by appearance. The markers and socket numbers shown in the partner product's installation guide take priority over assumptions based on cable orientation.
One Set Means Two Burndy Leads
This listing is for one twin cable set: one analogue Burndy and one digital Burndy. It does not contain two full sets or two pairs.
The NAPS 555 power supply, ND 555 network player and all mains or audio interconnect cables are sold separately unless expressly included with another product listing.
NAPS 555 and 555 PS Naming
Naim's current website uses NAPS 555 DR for the power supply, while product manuals and established system terminology also use 555 PS, CD555 PS and 555 PS DR. The Burndy set name refers to this power-supply family rather than to a general cable standard.
The presence of a NAPS 555 does not by itself determine which lead is required. The partner source decides whether it uses this twin set, one S-XPS Burndy or a dedicated New Classic cable arrangement.
Using the Set with the ND 555
The ND 555 requires separate analogue and digital Burndy connections to at least one 555 PS DR. With a single power supply, both leads connect between the correctly numbered source inputs and power-supply outputs.
Naim also supports an ND 555 configuration using two 555 PS DR units. In that arrangement the analogue and digital supply sections are separated between the two power-supply enclosures according to Naim's connection instructions.
Check a New ND 555 Package Before Ordering
Naim's ND 555 quick-start guide lists two Burndy leads among the accessories supplied with the network player. This separate cable-set listing is therefore most relevant when replacing a missing or damaged pair, completing some legacy packages or assembling a used system.
Confirm the contents of the exact ND 555 offer before buying an additional set.
Legacy NDS and CD555 Applications
The NAPS 555 twin Burndy set is also associated with compatible NDS and CD555 installations that require separate analogue and digital supplies.
These are discontinued products and may be offered second-hand with or without their original cables. Ask Audio T to verify the model, serial number, power-supply arrangement and required cable set before replacing missing leads.
Do not assume that a cable supplied with another Naim power supply or source is equivalent, even if its connector shell appears to fit.
Not the S-XPS Burndy
Products including the NDX 2 use one S-XPS Burndy when powered from a compatible 555 PS DR or XPS. That single lead has a different application from this analogue and digital twin set.
Other examples that commonly use a single source-power connection include the NDX, original ND5 XS, HDX, Naim DAC and NAC-N 272. Their manuals and exact revisions should still be checked individually.
Buying the twin NAPS 555 set does not provide a substitute for a missing S-XPS lead.
Not the New Classic 555 PS Cable Set
New Classic products use dedicated transition cables when partnered with a legacy 555 PS DR. Naim identifies separate digital and analogue 555 PS-to-New Classic leads under different part numbers.
The published New Classic references are 00-010-0242 for the digital lead and 00-010-0243 for the analogue lead. This legacy NAPS 555 set, part number 00-010-0108, should not be ordered for an NSS 333 or NSC 222 without explicit confirmation from Audio T.
Keyed Multi-Pin Locking Connectors
Burndy connectors bring multiple dedicated conductors together in one locking assembly. Their locating keys and pin arrangements are designed for a specific connection rather than universal interchangeability.
The locking collar secures the plug after it has been aligned and inserted correctly. It should never be used to pull a misaligned connector into its socket or to overcome resistance from incorrectly positioned pins.
Naim describes Burndy cables as carrying both power and signal. In this NAPS 555 application the cables form the specialised multi-conductor connection between the power supply and source; they do not replace the source's normal DIN, RCA or S/PDIF audio output cable.
Published Cable Construction
The published Burndy cable data specifies double-screened high-conductivity copper construction, 55pF per metre capacitance, 75-ohm characteristic impedance and a 1mm² copper core.
Standard cable length is 1.25 metres and the published cable diameter is 7.5mm. The cable is supplied in black to match Naim equipment and surrounding system cabling.
These figures describe Naim's published cable characteristics; they do not mean that the Burndy set can be used as a standard 75-ohm digital coaxial cable.
Safe Connection Procedure
Switch off the entire audio system and disconnect the relevant equipment from the mains before fitting or removing either Burndy lead. Never make or break a multi-pin power connection while a component is energised.
Identify the analogue and digital cables, match them to the correct socket markers and align the connector keys carefully. Insert each plug straight into its socket, then secure the locking collar by hand without twisting the cable body.
If a connector does not locate easily, withdraw it and recheck its identity and orientation. Do not force the plug, bend pins or use tools on the locking collar.
Cable Dressing and Mechanical Care
Arrange the equipment so that both 1.25-metre cables reach their sockets without stretching, sharp bends or torsional strain. The leads should form relaxed curves rather than supporting the weight of another cable or being trapped behind the rack.
Avoid pulling on the cable itself when disconnecting. Release the locking collar and handle the connector body, supporting the lead so that its weight does not bear on the socket.
Keep the connector pins clean and dry. Do not apply contact cleaner, lubricant or unauthorised treatment. Cap or protect disconnected plugs so that pins cannot be bent during storage.
Checking Used or Replacement Cables
A used pair should be checked for matching analogue and digital identification, correct connector keying, intact locking collars, straight pins and undamaged cable jackets.
Stop using any cable with bent or recessed pins, a loose connector shell, crushed insulation or intermittent operation. Burndy assemblies should not be rewired or repaired as a home project because an incorrect connection may damage the source or power supply.
If only one cable is missing, confirm whether Naim supplies the exact single replacement before mixing leads from different sets or production periods.

Frequently Asked Questions
How many cables are supplied?
Two: one analogue Burndy lead and one digital Burndy lead. They form one complete NAPS 555 cable set.
Are the two Burndy leads identical?
No. They have different roles and connection configurations. Keep their analogue and digital identification intact and connect each to the corresponding marked sockets.
Does the set include a NAPS 555 power supply?
No. This listing is for the two Burndy cables only. The 555 PS or 555 PS DR and the source component are separate products.
Do I need to buy this set with a new ND 555?
Usually not. Naim's ND 555 quick-start guide lists two Burndy leads among the network player's supplied accessories. Check the exact retailer package, especially for used, ex-demonstration or replacement purchases.
Can it connect an ND 555 to one 555 PS DR?
Yes, when this is the correct genuine cable set for the units. Both the analogue and digital leads are used between the correctly marked inputs and outputs.
Can the set be used with two 555 PS DR units?
The ND 555 supports a two-supply arrangement in which its analogue and digital power sections are separated. Follow Naim's instructions and ask Audio T to verify the complete configuration.
Is this the Burndy cable for an NDX 2?
No. The NDX 2 uses one S-XPS Burndy when connected to a compatible external power supply. This product is a different two-lead set.
Will it connect a 555 PS DR to an NSS 333 or NSC 222?
Do not assume so. New Classic products use dedicated transition leads with different Naim part numbers. Ask Audio T for the correct analogue and digital New Classic cables.
Can I identify compatibility from the number of pins?
No. Pin count, keying, internal wiring and the products at both ends all matter. Use the exact Naim part number and confirmed system application.
Can the cables be connected while the system is switched on?
No. Switch off the entire system and disconnect the relevant equipment from the mains before fitting or removing either Burndy lead.
Should the locking collar pull the connector into place?
No. Align and insert the connector correctly before securing the collar. Never use the collar or tools to force a misaligned plug into its socket.
Can a damaged Burndy cable be repaired at home?
No. Stop using a cable with damaged pins, connectors or insulation and consult Audio T or an authorised Naim service route.
