Default Which Pass Aleph diy board choose for no compromise headphone amplifier?

Dear Pass Diy Forum,

I’m an Italian student who would like to use a Pass Aleph as amplification of my main listening system: reference headphones.

Very unpleased of commercial products (under 3000 Euro), I’ve already build some good sounding amplifiers; but now, with the “knowledge” headed up, I would like to build a “no-cost-object” class A headphone amplifier. (Something like Rudistor RP010 for example)

So I would like to ask You if one of the Aleph diy boards could be useful for that utilization (possibly with 20/30 watts on 8 ohm, 10 mV, able to drive headphone impedence from 32 to 300 ohms), or if I could look for something different, or if some modifications are necessary on the boards, power supplies voltage, ect., for an high-end result.

Thank You very much indeed in advancefor any suggestions or advices,



with kindest regards,


Davide

If you don't need voltage gain I would go with EUVL's DAO JFET Follower.
If you need some voltage gain I would probably go with something like an F3 or possibly Pass DeLite with depletion mode Power Jfets.
However you could make an Aleph J or F5. If you like experimenting build all of them.

If I could only have one amp, my vote would go with the DAO JFET Follower. The Denon AH-D5000 or AH-D7000 headphones are a great match for this amp

Edit: If you want to use this amp for both speakers and headphones, then probably go with F5.
The M2 is also a very interesting design as well as the J2, however only basic circuit topologies are available so there are no guarantees on how good the end product will be.

It might come down to whether you want the absolute best headphone amp or the best compromise for both headphone and speakers.
If you want absolute perfection, I would build a dedicated headphone amp.

Or you could...

go back to the headphone section of the forum where you have asked the exact same question

where you have about 11 replies already

where we have asked you on two occasions which headphones you actually want to power

where you still have not answered that basic question
