That is a pretty open-ended question -- a good one. The Z4 you are planning should do well. I'd probably pull out my PP EL34 amp and tweak it up Allen Wright style (about 10W). If you were going SS you'd perhaps want a little more power since a SS amp typically isn't as graceful when pushed -- a nice little 25 W amp say.

It wasn't the 21 inch woofers that got the askance looks, they were hardly worthy of notice.

Venturing up to the sales counter with 65 bags of dacron stuffing in four shopping carts caused the store regulars to gawk and gossip, however.

Kent,

Sounds like you're planning a pillow fight as a sleep over event. It would be more fun with feathers

…because the Aleph 3 and zv4 share nearly the same output stage. They have the same constant current Source…

I wonder why Nelson Pass is deaf to this.
Aleph 3 and ZV4 have active current sources, not constant.
The active current sources have the function to characterise
amp’s damping factor.

If the amp’s DF mismatches with a speaker set, tweaking
the fracture of the active current source could cure it. This
is a great advantage for us. Detail about the tweaking is in the
Nelson Pass’s article on ZV2.

Probably, someone was too busy to tell somebody the tweaking.

“Fraction” must have been better than “fracture.”
Silly…

Well, the feedback from the “Jordan 92S TL + ESg2 ribbon” thread seems very positive. I think I shall most definitely build the Jordan 92S TL and add the external ribbon later, as time and money permit. The only problem I have now is that, a few days ago I was shore that the ZV4 was the right amp for me. Now I’m not so shore anymore. I may build the zv4 or the Aleph30. I just hate it when that happens. Every one who has built it seems to agree that the Aleph30 and ZV4 sound very much alike and that the Aleph30 definitely has more base because of its lower DF. The question that I must ask myself is, is the extra cost of the caps for the three rail power supply and the extra cost of buying more mosfets and matching them worth the extra octave of base I get. You don’t have to answer that, I’m just thinking to myself.
