Best Pass amp

MikeW · 3rd November 2005, 04:38 PM

Out of all the Pass amps built from this forum, which is your favorite?

What are you building now?

I've built an Aleph 5 (so it's my favorite for now). I have an Aleph 4 in process which means the main boards are stuffed and tested. I also have the chassis nearly finished. I have boards ready for the Aleph 2 as well. After that will come the Mini and the A30 and the Aleph X. Then I should be able to answer your question more fully.

Jam how do your DIY's compare to your X-600's?

Hi Mike,
I like my mini better than my 30 for a few reasons. Mainly I think it sounds better.

I'm currently building a BOSOZ, all home done.(long project)

Next is an Aleph X with~ 31-32v rails and an old ~3kva EI traffo. My heatsinks are all saved up and um, I'm gonna use a lot of output devices. Probably a number somewhere in the magnitude greater than that of a Pass commercial amp! My garage heater doesn't cut it as I get older

(longer project)

Mike, you suggested I make something big. Will that suffice?

Why on the axe spreadsheet does it NOT reflect a power increase at rails above around 28v. The sheet seems to max out around 144w into 8R. Do I have an old sheet??

The best amp is the amp that one finishes... and learns from : )

(i prefer my Aleph 2's)

((i learned the most from my Zen)

My favorite is my MiniAs...inspired by Pass.

They are my only Pass amps for now.

I have built most of the Zens. Some of them sound pretty good. Most get taken apart for other projects. Good thing he goes step by step so he doesn't loose me. There is a lot to learn. Dual differential cascoded jfet bridged balanced single ended class A. Sounds like a new Aleph-X.

I still like the little Alephs (A3, Mini-A). I am sure there is something better on the way.

Why don't you try F1?
With Aleph current source . . .
With a little bit feedback . . .

Hmmmmmmmm . . .
