Pure Class-A Amp under $2000 (USED)

@darkknight8586 I believe Krell KSA 150 and 250 operate in Class A and deliver plenty of power. There are some other Krell models such as sustained plateau biased models also operate in pure Class A. There is one KSA 150 available for $2,500 if you are interested. KSA 150 burn 300W when at idle! Class A efficiency is very low around 10-15% tops. For this reason, I purchased little brother in this series KST 100, but Class AB biased. Imaging, depth, spacing around instruments are outstanding.

It seems that Sugden is quite favourable by many users, and they look very nice

@pwerahera how do you feel about the sound of Krell? I heard they have a very forceful bass.

I have a LUXMAN 550ax2 in my tannoy system but just picked up jungson ja88 used for £400 ($470) and amazed ... Need to drop into the main system as think it could be as good as the luxman ... It's a bit more powerful

It does suck about 380w from wall and get warm which is fine here in Scotland ....

Built very nice but heavy at 27kg and big so you need space on a rack or sideboard.

whatever you do, steer clear of that Emoteva tripe.

gain is ultra high, you will have tweeter hiss

plus the service on them is a disgrace to audio.

they are ok for what they are entry level stereo separates .

nothing more.  i did hear the new flagship speaker was fairly descent, despite the very low Watts/current allowed. for such a good size speaker, i think its only 250W

i do like the folded horn tweeter if the source material is well recorded.

heavy metal through the Emo amps was painful, they are bright, even with a 92 1w/1m pair of old speakers i had 15+ years ago.

they were ok for country, or reg rock, but metal,...aaaarrrgggghhhhh shrill, i even switched speakers, and still shrill and molar grinding.

had the xpa-1 monos.  big bulky, and those knight rider like blue meters on the front were making the amp look cheap and low end. as it is. i had them shut off from first warmup.

if you know about class A, im sure you know about that Emo mess

KRELL KSA 50 or KSA 100, both fantastically musical amps, and when funds permit an Audio Research pre an SP9 or LS2B.

I know they are old uns but are good uns, maybe not as detailed as later models but more engaging and less Hifi sounding.
