The NS10 really isn't that fussy about the power amp. There's lots of decent second-hand pro and good hi-fi amps around that would do a good job. If you want to go down the (generic) class-D route then look at the Hypex modules and kits.

Thanks for the reply Huge! I was under the impression NS10s are very picky. I hear people talking about nothing under 125 watts a side etc..

Anyway, I have a few Power amps kicking around the studio but none of them where mentioned in any post I saw... probably because there all on the cheaper budget side.... would any of these do a decent job?

Crest Audio LA-901

Behringer KM1700

Crown XLS202

if not would your recommendation be to go new or something used if I had between $300 - 500 usd to spend? Any suggestions?

I appreciate your thoughts on this so much... so much chatter out there on the subject.. makes my head spin.

Secondhand Quad 405? At laser you’d be in period, they were quite popular with the NS10.

Okey, I see them. Decent price. I see that there are also new clones... any thoughts on those?

Any thoughts on the original Bryson 3B? Not the ST or SST version... the older 3B. They any good with the Yamahas?

Maybe I was unlucky but the Teac amp that we had in the studio really brought out the worst in them.

I haven't tried a new 405 clone although the modules are so cheap that it seems tempting. However, having just done a little searching, it appears that they are based on a very early version of the 405 and suffer from all the disadvantages such as high noise levels and a mistake in the Zobel network routing. I'd prefer to go for a genuine 405-2.

Interesting, clones no good then. 405-2 is the right model.

One other thought - if you are into DIY you could always remove the insides of the Crown or Crest amp that you have already and replace them with Hypex modules which should be within your budget. I did a similar thing with a noisy 405 a few years ago and it cost me around £250.

Don’t mind doing that at all. Can you link me to what you used?

The closest that I can find to my setup is 2 of these

https://www.diyclassd.com/product/ucd180hg-with-hxr/5

coupled with one of these

https://www.diyclassd.com/product/smps400a180/138

and the matching power supply cable set (I think I made my own amplifier cable set).

They only sell the upgraded amplifiers now which adds around 60 Euros to the total cost compared to my build.

I’d say you want to steer clear of lean sounding bright amps, the 405 is fine, it’s got some grunt and isn’t too bright. Audiolab 8000A is another one to consider, very nice amp, quite neautral.

Go on ebay or your local pawn shop and look for high quality old stereo equipment.

There is some great stuff out there.

Intriguing... define 'worst in them' please! ;-) I think I've only knowingly heard one Teac amp, and I wasn't enamoured. As I recall, I thought it sounded 'fizzy' and lacking control.

However, having just done a little searching, it appears that they are based on a very early version of the 405 and suffer from all the disadvantages such as high noise levels and a mistake in the Zobel network routing.

That seems a disappointing cockup. Which clones are these? I think there are a number of different ones about aren't there?

It was a Teac AX75 amp Hugh - originally sold by Thatched Cottage Audio to partner the NS10's. Plenty of power but with an exaggerated high end.

I just did a quick Ebay and Google search where it seems that the Chinese 405 modules are often proudly sold as Mk1 modules with NOS 301 op amps. Other forum comments turned up the issues with the early modules and mentioned the fact that the design was taken from a published article which presumably gets around any legal issues. I see there are also a few that are marked 405-2 which, if they are accurate copies, will have overcome these issues although they possibly could do with a few mods to optimise their sensitivity for studio use.

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.hugh

A bit late as I've been travelling down to the coast but Quad were not remotely interested in fixing my 522, or advising the engineer who was attempting to fix it (he failed). Thankfully Folderol has sorted it out for me (I have yet to plumb it into the studio and my period correct Kef 104ABs, sorry Foldy :blush: ). There were a couple on ebay in much better condition than mine, the cheaper went for about £250 IIRC but I wanted my 522 fixing partly for sentimental reasons, I've owned it for around 30 years, and partly to avoid another bit of kit ending up in landfill.

OTOH, I did buy a mint condition StudioSpares Titan 600 off ebay for £65 delivered a few weeks ago so bargains do exist.
