Default Aleph amp questions

Having completed the F-5, I am very pleased with its performance overall.
I would like to have more gain, so am looking for a more powerful Pass amp.

I keep bumping into the various Aleph amps people are doing
diy, and have a few questions:

For a more powerful Pass Amp, (and more gain as well) is the Aleph series the way to go, or are there others?

If aleph is the way to go, which one and why? I see links various places for the article and service manuals, but they go no where. Is there someplace I could see them maybe I could figure it out?

I see on the chip amps dot com site aleph boards. Can all the alephs be built from these? Or just one particular Aleph? does it have more gain?

I'm looking for more gain than F-5, will the Aleph get me there, or is there a better option. I have 25 watt amps that have WAY more gain, maybe its just more gain I need.

Thanks for any help with these Pass Newbie questions!

When anyone starts talking about more power, that
tends to steer them away from Alephs. It's not like it
can't be done, but usually it's more effort than you
probably want, and the performance will not be as
dynamic as many people expect from higher power amps.

Perhaps it's time to consider a high wattage DIY project.
Previously there was the "Pass Monster", instigated by some
member here, but they pooped out on it.

I guess I have to do it myself - the guru's work is never
done....

thank you for your response. The F-5 is too good! I love the thing, I just want as much of that sound as I can get in a higher wattage amp. I'll await the Gurus work......I take it from your comment it doesnt exist yet, so I will wait. Thanks for the interest.

Was there a thread on this 'Pass Monster"? I'll be searching!

Thanks again,

russellc

1000 watts is a "little" bigger than I'm thinking of. I was more along the lines of 50-200 watts. Shoot, its not necessarily the power I need, (My MC-225 will rock the speakers at question) More gain would likely do it.
But all that power may be the answer as well.

I haven't stopped rambling since.

As suggested earlier : Aleph 1.1 , does Push-Pull tricks for the hungry.

(add a JFET universal gain stage, go balanced, do some cross coupling, and...naah)

Jacco, where can I learn about this Aleph 1.1? I would need fairly clear instruction, but I'm all about jumping in WAY over my head. So, do tell!
I'm all ears!

And thanks for the response. i can build this sucker while the Master contemplates a higher power masterpiece!

I would probably build a high powered BA2.
In the process of buying the pcb's you will also support diyaudio.com
