Default Class A amp dilema

Hi friends,

I built an Aleph 5 with no exotic parts and a liked a lot, never listen nothing like that. But i want to build another class A amp . What do you recomend, Aleph 3 or JLH ? An Aleph 3 (with original bias) sounds better than an Aleph 5 (with original bias) ? Could you help me in this dilema ?

Nice to meet you and best regards.

By the way thanks to Mr. Pass for his beautiful designs an a wonderful sound !!!!

The application of this second amplifier will be the determining factor.

The Aleph-X is popular and would be a nice step up in difficulty from an Aleph 5. It also happens to have a different set of trade-offs that many prefer around here. This amp is also easily scaled up or down. If you're interested look at the wiki, or this link http://www.facstaff.bucknell.edu/esa...s/aleph-x.html as the Aleph-X builder’s thread is somewhat overwhelming

The Mini-A or Mini-Aleph is also a nice job to dispose of some left over parts in a very productive manner.

I would also recommend a look (perhaps a brief look) at the Son of Zen. If you have an appreciation for minimalism this schematic is really a work of art. I have dismissed this topology due to the $/watt final costs of the amplifier.

Cheers and best of luck.

Give us some feedback on your speakers, your room, your listening preferences, your goals, and your budget and MUCH more specific help will be able to be given.

Thanks for plugging my web site! I'm still pretty early in the process for building my Aleph-X and am trying to document everthing that I do so that others can easily build their own. The Aleph-X wiki is a great place to start, but for someone with little experience (like me) there are still a number of things missing from it.

I prefer JLH, but Aleph3 has better low end and works better with more speakers.

Default thanks for the replies felows

Nice Aleph-x site, maybe in the future i will build an Aleph-x.
In truth, now i prefer the small projects , less power (cost) but best dynamics and bass i guess. Maybe i will go for a jlh, to taste some diferent sound of Alephs. By the way, i´m very happy with the sound of my hot Aleph 5 (now i´m changing some parts , better parts).

best regards.

If you like the JLH, you might want to wait a couple of weeks
for the PLH.

You are assuming bipolar devices, it seems. Maybe, maybe not...
