Should I got full tubes or stick with hybrid amps?

I currently have a Jolida 1501. I like it but I think I have upgraditis. I originally bought it (hybrid) because I’m really sensitive to highs (get a headache). It’s been good to me and I can listen without fatigue.

To help with upgraditis, I just bought a Yamaha AS801 to try out and although it definitely sounds good and has nice detail it is creating a little fatigue for me. I’m still in the break-in period so this may smooth out a bit.  (I definitely like having bass/treble controls).

Thinking about picking up a full tube amp or another hybrid for comparison. I don’t know much about other manufacturers of tubes/hybrids.

What’s the difference (sonically) between a hybrid and a full tube amp? Any recommendations?

Thanks!!

Curious as to whether you have tried different 12ax7's in the Jolida.

The Jolida uses the tubes in a buffer stage (the preamp section is passive) but, they will still affect the sound.

I've tried a few different tubes.  Right now I'm using GE 5751 from 1955.  I had Mullard 12AX1s from '67 before that.

Room acoustics are probably not great.  Hardwood floor with an area rug covering most of it.  Hard objects everywhere....

Am I right that the hybrid should have the warmth of the tube amps and the bass of SS?  So, the best of both worlds?

Onix Rocket RS750. I really like them. Laid back.

Really depends, but the general practice of using tubes for color and warmth, with SS amps for better speaker control is often the right approach, but not all tube pre's or SS amps are the same.

Do this experiment, throw some blankets around the room, and pillows. Especially include the floor between and behind your speakers.  Also experiment with the walls.

I suspect your opinion about what you need may change if you do this.  Let us know. :)

Best,

Erik
