Modern Class A SS Integrated Amplifiers

As above any Luxman *Used only* will meet your price. Rare to find , but There are 2 right now at listed at US audio Mart For great price. Excellent stuff. If you want new, Power Modules Belles Soloist 1 is $2900 masquerading as a $5000 INT. Amp. 100 at 8ohms/150 at 4ohms. Very stable, Black background, wide S/N ratio and channel separation. And 2000 damping factor if that means anything to you. I have owned both after too many others auditioned. NO BETTER bang for the buck than Luxman used or a  new Belles.

Plinius SA 103, 102 or 100.  100 watts into 8 ohms, switchable between Class A and Class AB.  I use an SA 100 mk III on Class A when listening to music and AB when using it in the HT system.  Plinius has a nice smooth "analog" sound that is great!

Cal3713-

how did you like the Pass Labs/Thiel combo?
what cabling did you use?

Surely look at First Watt

I don't know if this will be in your price range but take a look at the Grandinote Solo, 60 wpc of pure class A, remotely controlled and you can select streamer-DAC or pre-phone built in...The price is out of your request but perhaps you can find some other model at a lower price.

They make the very acclaimed Shinai, 37 wpc in pure Class A but you will need an external DAC/ Pre-phono. A lot of very very good reviews on their website... 

Hope this can help,

Good listening!
