{"product_id":"naim-cd555","title":"Naim CD555 Reference CD Player","description":"\u003cp\u003eFirst shown and demonstrated at The Hi-fi and Home Entertainment Show at Heathrow in September 2005, Naim's reference CD player, the CD555 with 555 PS delivers the ultimate musical performance from a CD.\u003c\/p\u003e \u003cp\u003eThe CD555 makes no attempt to play DVDs, DVD-As or SACDs. It does not have a digital output. Nor does it have a variable output. The CD555 simply plays CDs and at that it excels. We are confident that it is the best CD player ever.\u003c\/p\u003e \u003cp\u003eKey features of this fabulous player include a separate power supply from a transformer secondary winding, which is triple regulated, right through to the critical master clock and de-jittering circuitry. Special attention has also been paid to reducing capacitive coupling of high frequency noise from other supplies into this super quiet clock supply through interconnect cables and wiring looms. Two Burndy interconnects between the power supply and head unit discretely carry the digital and analogue supplies, and extend the principle of reducing capacitive coupling between power supplies as far as possible.\u003c\/p\u003e \u003cp\u003eThe power supply incorporates significant upgrades over existing designs. More regulators have been used to isolate the supplies to various parts of the circuit, minimising their interaction.\u003c\/p\u003e \u003cp\u003eThe CD555 Digital-to-Analogue Converters are mounted in a \"quiet room\". Apart from ensuring that all critical signals reaching the DAC have immeasurably low jitter the chips are inside a shielded enclosure to keep their environment free of the varying electric and magnetic fields that inevitably occur in a CD player, so enabling the converters to do their work, isolated from all external influences.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eOther noteworthy design features of the CD555 include:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMachined, heavy, solid, transport tray to reduce resonance and vibration amplitude.\u003c\/li\u003e \u003cli\u003eHigh mass design to improve suspension characteristics, providing isolation from the chassis and other components.\u003c\/li\u003e \u003cli\u003eLow infra red reflective coatings around the CD to reduce eye pattern interference and noise.\u003c\/li\u003e \u003cli\u003eExtremely low inertia and low resonance CD clamp.\u003c\/li\u003e \u003cli\u003ePhilips CD-Pro mechanism with a die-cast chassis.\u003c\/li\u003e \u003cli\u003eVery heavy brass sub-chassis - separate for digital and analogue electronics.\u003c\/li\u003e \u003cli\u003eAnalogue stages, I-to-V conversion, filtering and output driver are built from discrete components.\u003c\/li\u003e \u003cli\u003eSeven-pole output filters.\u003c\/li\u003e \u003cli\u003eSeparate low jitter clock circuit with its own multi-stage regulated power supply.\u003c\/li\u003e \u003cli\u003ePost-digital filter de-jitter circuitry to eliminate jitter.\u003c\/li\u003e \u003cli\u003eDAC's are isolated from electric and magnetic fields.\u003c\/li\u003e \u003cli\u003eMotorised top loading door.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDesign features of the 555 PS include:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSeven regulated power supplies including a separate one for the clock circuitry.\u003c\/li\u003e \u003cli\u003eFive secondary windings on the transformer.\u003c\/li\u003e \u003cli\u003eA transformer that is 40 per cent larger than that in the XPS2.\u003c\/li\u003e \u003cli\u003eSeparate dedicated analogue and digital output sockets (Burndy) to minimise high frequency noise modulation of analogue supplies.\u003c\/li\u003e \u003cli\u003eBackward compatibility with the CDS3 and CDX2.\u003c\/li\u003e \u003cli\u003eCan be used to enhance the performance of the Naim HDX hard disk player or DAC.\u003c\/li\u003e \u003cli\u003eA low resonance case with isolating feet.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Naim","offers":[{"title":"Default Title","offer_id":49950457299301,"sku":"CD555","price":32995.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/5440\/4453\/files\/product-no-longer-available_5a92c2d7-04aa-433c-a378-326f1fae6b1c.png?v=1763413379","url":"https:\/\/trutone.ca\/products\/naim-cd555","provider":"Trutone Electronics","version":"1.0","type":"link"}
