Anyone know of some small class A/B or G but not D power amplifiers? Ideal size is W: 9" (230mm) H: 2 1/4" (65mm) D: 6" (160mm)

I need one for my desktop but don't need DAC or volume control or anything.  Don't really need more than about 25W but more might be better.

I know about Parasound Zamp but I am hoping to find something different, hopefully better, slightly smaller.  The Dayens Ampino looks good, too.

1U rack size is way too big, like double the size I'm looking for.  1/2 rack or 1/4 rack is about right if the depth isn't too extreme.  Again, ideal size is W: 9" (230mm) H: 2 1/4" (65mm) D: 6" (160mm)

I wouldn't dismiss the Parasound. Not for a second.

I have a Zamp.  It's ok.  I like the connector layout on the Spark better.

Dayton APA150 is very good. Don't let the low price fool you.

I too have a little tripathi. Pretty dang good.

For real.  I frequently demonstrated one in my system in place of my "good" amp.  It's impressive if you don't need more power.

Perhaps a Chord?

I had an Ampino with the better caps but sold it after I tried the TBI Millenia MG3 Class BD Integrated Audio Amplifier. This amp had better detail and more transparency. Not a pure D, but a BD amp. You can get this for $500, and sounds great even on Quads. Very small!

You can also run it on battery if you prefer. I never tried the headphone section, but it also has that option. You can run it on the side. I used it that way also.

I own some TBI products.  Nice outfit but I don't see any physical measurements posted for that.  Can you measure it, please?

I was reading that the APA150 was originally some Emotiva, which speaks well for it.  But @12" deep I'd like smaller.

I tried a Chinese amp with those dimensions and the depth really didn't work.  The amp itself also didn't work at all after a few weeks

I've had the Jolida 301 for some time and really enjoy it. It uses a pair of 12AX7s as the input gain stage.

I'm not interested in tubes.  Seems like a very slippery slope

+1 on the Ampino. I had one a while back. It fits your size requirements and sounds mighty fine.
