For sale: Nord One Up NC500DM MKI Dual Mono Stereo Power Amp in Black. £825.00

This is a Dual Mono Power Amplifier with 2 x Hypex NCore NC500 modules, 2 x Hypex SMPS1200A700 PSU's and 2 x Nord UP Rev C Input Buffer Boards.

This was the more expensive version with Sonic Imagery 994 Op amps. It is a terrific amplifier. It delivers plenty of power and can drive some very demanding speakers. I have paired it mostly with ATC floor-standers, also Revel and Q Acoustics stand-mount designs, all with superb results.

Condition is very good. This is the earlier three-quarter width case. It has some slight signs of use as the brushed metal case can show fingermarks, being a functional rather than super-luxury finish. Balanced XLR inputs only, and if you don’t have anything suitable, I can lend you some phono to XLR cables. Nice chunky CHK binding posts accept bananas, bare wire, and presumably spades and pins - though I’ve not tried anything but bananas myself. If you’re allergic to blue LEDs then you won’t like the bright front on-off switch! Relay delayed switch-on means zero thumps, and no extraneous noises are audible to me. This amp just gets on with the job - no fuss, and low electricity consumption.

It’s possible to change the Op amps and/or upgrade to the new Rev D boards if you wish to tweak the sound. I’ve never tried this, but there are reviews on line, including from the Wam’s George47 amongst others.

I bought the Nord in January 2021 to use with my Linn streamer-preamp. I have now found a Pass Labs successor, so this amp needs to find another home. The original purchaser told me he bought it in 2017, which tallies with the serial number sticker that appears to state 1/17, so it’s presumably five years old.

One slight cosmetic issue is that label on the back, close to the Left speaker CHK-brand binding post, has lifted slightly. I believe later models had etched labelling.

Collection possible from near Abergavenny, Monmouthshire - about 30 minutes from M4 and 50 minutes from M5. Demo also welcome, by arrangement.

Original packaging and box available. Not pictured as it’s in the loft.

Wammer’s Price:- £825 delivered in UK by courier. (The nearest current model has a full-width case and a later Rev D board - retail c. £1,724 inc VAT.)

As George’s review isn’t linked on the Wam since the site was upgraded, I’ve attached a copy here.
