SS amp with tight deep bass ?

Sufentanial,
The EE Minimax has very good bass. That's why i'm keeping it. I love that little preamp and i'm building the system around it. It's very fast too.

What speakers? This will provide a bit more direction in recommending an amp.

I have found few that can compete with the Krell's. Maybe an older Krell (KSA) at this price point (but I would want to know the caps have already been replaced in buying one of these or expect that you will be footing that bill).

While I don't care for Class D amps (let's just leave that alone and not hijack the thread), lots of people have good success with them and they are usually much "cheaper" price-wise. I'd check into some of those threads.

Legacy Classic speakers.

Good bass is more a function of the amp/speaker interface and the room than the amp itself.

IMO

Pay attention to Audiofeil's response.
