buget used amp ?


I would like to find a nice budget amp to compliment an Adcom GTP-500ii, the amp will be power Thiel cs 1.6.  The Pre Amp and Speakers will not be replaced.  Thoughts? Thank you.

Nakamichi PA7. The Nak’s are nice old amps and it will drive your Thiel’s no problem. Your Adcom is going to set your bar, meaning the Nak is capable of more revealing preamps. Not sure you’ll find one for $500 but probably closer to budget than finding a Parasound A21 as mentioned which is a very nice and the better amp. The A23 isn’t as good as the A21 and I’m not sure it will drive your Thiel’s that great but with its limited power your Thiel’s may sound a little thin and bright... I do have experience with your 1.6’s.  Depending on your taste of music, a Aragon 4004 will open your Thiel’s up no problem. I wouldn’t call the Aragon the most refined amp, but it’s still very good, but a brute with authority. Your Adcom will probably sound really good with the 4004. Your 1.6’s are more efficient than the bigger Thiel’s, but being a 4 ohm I’d  find a brute to open them up. If you can find a McCormack DNA1, that would be a nice amp too.

Parasound if you can find one.

An Adcom. I have a 5800 that I retired quite a few year back, they will push a speaker and sound quite good. The 565 MB had leaky caps when they were fixed they were a beast. The 5800 or 5802 were a good sounding unit.. 4-700.00.
The 585s not so much..
5500 were great if they were reworked a bit..

I liked certain Adcoms, I had them all.. I used Mac tube gear as a pre amp, Mercy they would liven an Adcom right on up.. Amazing..

There are two Amber Series 70 amps available now on eBay. $325 + free shipping. $229.99 + $61.25 shipping. I own one myself! Outstanding SQ and able to deliver high current into low impedance speakers! An easy recommendation for you! Why pay more? The Amber amp was very favorably. reviewed by The Audio Critic. 
Hey Guys,

Thank you for all the replies I will be doing some research today.  Keep them coming.  Unfortunately due to COVID Ive had to sell all my McIntosh :( but what I find odd is since using the Adcom Pre with a GFA 5300 I have more volume and bottom end than ever before.  But I lost some soundstage and air hoping i can find a good band aid until I get back on my feet.
