Its sensitive electronics are mounted on a brass sub-chassis suspended on coil springs to isolate them from vibration, and the power supply lives in a second box, the 552 PS, with an 800 VA transformer, three smoothing capacitors and Naim's DR discrete regulators. Seven DIN and two RCA inputs are assignable, two can be set to unity gain for an AV processor, and listen and record banks are independent. Volume and balance use precision rotary potentiometers under remote or front-panel control.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 20px\"\u003eThe NAC 552 belongs in Naim's reference system with the NAP 500 DR and ND 555. It is the choice for a listener who wants Naim's classic analogue architecture at its most resolved; the New Classic NAC 332 offers balanced inputs and a headphone amplifier at a third of the price.\u003c\/p\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eKey technologies\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 20px;padding-left:18px\"\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eTwo-box design.\u003c\/strong\u003e Preamplifier and 552 PS separated to keep the power supply's fields away from the audio circuitry.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eSuspended brass sub-chassis.\u003c\/strong\u003e Audio electronics on a brass plate floating on coil springs.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003e552 PS with DR.\u003c\/strong\u003e 800 VA toroidal transformer, three smoothing capacitors and discrete regulation.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eFlexible inputs.\u003c\/strong\u003e Assignable sources, two unity-gain inputs for AV bypass, independent listen and record banks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eFinishes\u003c\/h3\u003e\n\u003cul style=\"list-style:none;margin:0 0 6px;padding:0\"\u003e\n\u003cli style=\"display:flex;align-items:center;gap:10px;margin:0 0 6px\"\u003e\n\u003cspan style=\"flex:0 0 18px;width:18px;height:18px;border-radius:50%;background:#242426;border:1px solid #d8d5ce\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eNaim Black\u003c\/strong\u003e \u003cspan style=\"color:#55524c\"\u003eblack anodised aluminium with illuminated logo\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin:0 0 20px;font-size:13.5px;color:#55524c\"\u003eNaim Classic 500 Series components are made in black anodised aluminium.\u003c\/p\u003e\n\u003cdetails open style=\"border-top:1px solid #080808;margin:0 0 6px\"\u003e\u003csummary style=\"cursor:pointer;padding:12px 0;font-size:16px;font-weight:600\"\u003eSpecifications\u003c\/summary\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;margin:0 0 14px\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 10px 7px 0;border-bottom:1px solid #d8d5ce;vertical-align:top;width:40%;color:#55524c\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:7px 0;border-bottom:1px solid #d8d5ce;vertical-align:top\"\u003eAnalogue preamplifier, two boxes (NAC 552 + 552 PS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 10px 7px 0;border-bottom:1px solid #d8d5ce;vertical-align:top;width:40%;color:#55524c\"\u003eInputs\u003c\/td\u003e\n\u003ctd style=\"padding:7px 0;border-bottom:1px solid #d8d5ce;vertical-align:top\"\u003e7 × DIN, 2 × RCA;
