I have a Rogue Sphinx v1 upgraded with Mullard cv4003 (12au7) tubes. It sounds awesome. Tons of power. It's a hybrid Integrated amp with two tubes for preamp and solid state for the amp. You may be able to get a used one for around $900 to $1000.
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?
