Hi there,

Can any NS10 users recommend a (new) amp?

2nd hand HiFi amp from ebay - something like a 30-50W Denon would be my first choice is cost is an issue.

For top end - and 100-200W power amp from someone like Chameleon would be fine.

Back in the day is would have been Quad

Second hand Hafler would be a good option.

There's a company in the US called class D audio who make (obviously) Class D amps, which sound extremely good. I have one on my NS10s. It cost about 400 quid shipped. It's really good.

How much of a bearing on the final sound of the NS10 does the amp used have?

Is the speaker demanding or forgiving? I've only ever use active speakers so this is something that interests me on a purely academic level ;)

All I can say is don't go for a Teac AX75 which is what my NS10's came with. It really seems to bring out their harshness.

Some people find Quad amps soggy and restrained but they make NS10's almost listenable in my opinion. The difference between the Teac and the Quad amps is fairly apparent but I would say that they are fairly extreme opposites when it comes to amplifier sound and most amps won't make such an obvious difference.

Personally, I prefer LS3/5a's to NS10's

The Yamaha P2160 would surely have been a suitable power amp for the NS 10's if you can still pick one up?
Or maybe not powerful enough?

The older Hi-Fi Denon amps were a great match as they were built to UK specs/sound and tended to slightly tame the high mids and boost the low end. When I replaced ours with a newer version of the same amp it didn't work as it sounded too harsh, so after some experimenting I switched to using a Roksan Caspian amp which is a great match.

With NS10, the amps matters a lot. The better the amp, the better they will sound. An ex BBC engineer use to come to the studio to test various prototypes of high end tube amplifiers he was developing with the idea of selling them to studios with NS10. The amps were in my opinion to week matched as they transformed the NS10 into incredibly good sounding speakers, defeating the whole point of using NS10!

As Flow says.
I've never met any speakers that have sounded so different with different amps and wires... from pretty good (Denon), better yet (Carver) to awful (Quad {sorry!}). Speaker cable also makes a big difference over long runs, again more difference than with many other speakers.

Don't forget to run them in... ;)

I thank you for your replies.

Unfortunately the responses here are similar to what I've already got from friends and colleagues, That is people recommend old discontinued amps or hard to source equipment.

I didn't explain fully. My existing amp (nondescript HiFi model) has broken so I thought i'd take the opportunity to upgrade. But i'd like to buy something now and I want something that's guaranteed to last (i.e., with a guarantee and therefore new).

Any suggestions on something new and readily available?

Unlike some here, I actually found the Quad 405 (hifi) or 520 (pro) amps worked very nicely with NS10s. Yes, they are discontinued, but they are easy to source second hand, built like tanks top last a lifetime, easy to maintain, and Quad will still service them to as-new condition for astonishingly little outlay, if necessary.

if you want something new, then the earlier suggestion of Class D amps in the US is a good one -- I've heard other positive recommendations for them -- and you can save money by building a kit yourself, or buying one ready made. Different mains voltages and balanced/unbalaned input options are available.

Failing that, I've had good results over the years with Rotel hifi power-amps...

I am a big fan of Bryston (1st choice) and Hafler (2nd choice) amps. A used Bryston 2B or Hafler P3000 would work very well.

Bryston amps are fantastic professional tools but it's a huge outlay. The Class D Audio stuff sounds, for me, clearer than Bryston, but it's not quite the same calibre of product. For example, it has gain pots on the back of my unit which need to be aligned to balance left and right perfectly...I do it with a volt meter and tone. The build quality of the cases is clearly not the same as a Bryston either...what is?....but it's 1/10th of the cost and I wouldn't trade mine for the 4B that a mate locally is running on his NS10's.
