buget used amp ?

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..

Respect

Yup that was the deal with me. I went with higher wattage amps on the Mac and they would just open up.. A C20 is the bomb for a great sounding Adcoms.. They all needed tone control, BUT good tone control. C20s have a Bass contour, loudness and tone control. The tube roll is icing on the cake.

Until then

Class ds are gonna be boomy and gloomy with that pre. Better off with an A/B of some sort..

What about Crown for the power and bang for the buck. You can always move it to a bass position and even go with a little valve amp for the mids and highs later on.. Keep the cost down but a plan for the future without breaking the bank..

Respect..
