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!!

Those speakers 88 sensitivity put you in the category of more power needed, I think you might need more money in your budget. 

Spread the difference over several years, then it seems easier.
How would you treat this room?

I gather you listen quite a bit from your desk.

1. In my office, I re-configured my desk, no drawers on the right, so that I sit off-center of the desk, thus centered on the speakers, and the monitor also centered on the speakers for all the music videos I stream.

Never better sound/imaging in my office.

2. Next: dogs OUT, the breathing, scratching, licking, lip smacking, farting of large dogs is not a good mix with concentrated listening.

3. I might try tilting those speakers up some, just to hear if any difference.

4. Do you pull that black chair out in front of your desk for focused listening? Slightly angled up might reduce tweeter’s output, may be advantageous regarding fatigue from such close focused listening.

5. Tubes: I say yes to all tubes, perhaps try something you can return or sell without too much loss.

two concerns.

a. speakers 88 db sensitivity, needs more power, i.e. 4 power tubes each side,

b. thus more heat. It seems like your equipment is behind those closed cabinet doors? Tube amps, especially that size tube amp wants lots of air for heat to escape.

6. Integrated Tube Amp, with remote volume, tone controls, and preamp bypass to bypass the tone controls if you want. Tone controls may be the best solution to your fatigue issue, neutral or adjusted for particular music.
Tubes Harsh? Huh?

I’ve used Tubes since 1973, 47 years, harshness never entered my ears.

always in the 30-35-45 wpc size (4 power tubes total)

Fisher Mono Blocks 80Z (EL37, substitutes)
Fisher Receiver 500C; 800C (7591, substitutes)
Current Cayin A88T 6550 or KT88

I think I put EL34’s in the Fisher Mono’s, -5 wpc, a vauge memory

Fisher’s used lots of 12...
Cayin uses 6....
Other Cayin’s now use 12 ....

I found both the pre 6’s and the Power tubes brands definitely sounded dirrerent/preferrable, but none sounded harsh.

I’m thinking I like the 6.... better than the 12 ....
