I’ve been using a Sugden A25B (34 watts in class A/B) for quite some years now and it does quite the task you are refering to... for the price I paid (200$ used), I doubt there’s anything that can even come close... it sounds warm but it's not the last word in transparency and details...
SS Budget "Tone" Integrated Amplifiers
In your experience, what are some good, inexpensive solid state integrated amps that give good tone / density? Is there such a thing? I'm done with tubes (for now) and spending $$$ chasing unicorns instead of listening to music. But I like instruments to sound like they should and not have poor recordings (which IMO are most) ruthlessly revealed. I can think of Sugden but it's all but Covid unobtainium right now. What else?
