NORD ONE SE NC500 MKII POWER AMPLIFIER

OVER THE COMING MONTHS WE WILL BE MOVING FROM 70 TO 88MM HIGH CASES AS WE EXHAUST STOCK BLACK MONO BLOCK IS NOW IN 88H VERSION CASE 

OVERVIEW

Our SE NC500 MKII are our updated second generation amp with new REV D input buffer which is a substantial improvement over our first generation REV C based amps. Housed in our beautiful built and finished Japanese cases, offering a level of fit and finish superior to the standard case, which is also used by most of our competitors.

 SE Case detail here

 

The NC500  UP uses REV C buffers and the MKII uses our new REV D buffers. Using a true Dual mono configuration with symmetrical internal and rear panel layout with short cable runs. To crown our SE Amplifier an Aluminium embossed Nord badge with new flush fitted Stainless steel switch.

All our amps are modular, PSU, AMP and buffer. Making them easily upgradable REV B to REV D so far. They are also easy to maintain. We have many early amps REV B buffered amps which have been bought up to REV D MKII amp specifications which can easily be done DIY.

Please don't ask us to compare to our NC1200 amp. Yes the NC1200 is better in every way, but then our NC500 MKII is better than most amps costing up to £10K. They are distinctly different priced amps if you want the best and can afford the NC1200, its the amp to choose. If you want a stunning amp that will out perform most £10K amps choose the NC500MKII.

The NC500 REV D uses modern versions of an old Op Amp used primarily in Studio mastering and mixing equipment. Their development was focused solely on Audio performance and have been bought up to SOTA design and performance. They will also accept previous 8 pin Sparkos and Sonic Imagery OP Amps.

Our World leading performance price ratio amplifier gets even better and is 100% backwards compatible with all our previous NC500 based amps. Upgrade REV D Buffers available for ALL older NC500 amps in Upgrade section of the shop

 

Running  into Class A delivering up to 250mA of Class A current fed into the Hypex NC500 module. The result is more tonal depth, dramatic improvement in bass, even greater depth of soundstage, slightly more detail all wrapped in a balance of rich texture and harmonics, bottom-end presence , amazing dynamics, exquisite resolution in the mids and upper frequencies, and a fully revealed, fully dimensional sound stage  Headroom and listening volumes have increased and all combine in a totally musical non fatiguing Class A sound. Gone, if there was any hint, of solid state amplifier.

The MKI uses REV C Buffer Board with choice of Sparkos SS3602 or Sonic Imagery 994 Op Amps.

After an intense development and Op Amp evaluation we tried 3 op amps, from John Hardy, Sonic Imagery and Sparkos Labs. Despite excellent reports on the John Hardy 990C we preferred the Sparkos 2590 and Sonic Imagery 990 Enh. Both are excellent the difference in presentation is less than with the previous versions we used. We much prefer the Sonic Imagery. The Power sections Panasonic electrolytic capacitors value were chosen to deliver the best and fastest combination of attack and sustain the bass notes, small values have a faster flinch capacity to deliver crisp bass. To small and they run out of power to deliver sustained bass. We evaluated multiple devices before settling on 22uF. 

The new REV D buffer will also accept the two previous Op amps The SI994 and the Sparkos SS3602 in DIP8 packages. We have also further enhanced the peripheral circuit implementing further counter noise reduction. The new REV D is 100% compatible with our previous MKI amp and offer upgrades to the new spec. 

The new amp also benefits from a new symmetrical internal and rear panel layout resulting in shorter internal cable runs. We have also rebated the front Stainless Steel switch for a cleaner front panel (photos are not rebated) which has a Dim and Off setting via the back panel.
