Dear Nelson,
I couldn't find a better power amplifier than my X250.5 simply because you haven't built one yet.(stereo not in monos form, space is premium for me) There must be a super stereo amplifier from Pass within 10k-20k usd range. I don't know how you will manage this but it has to be done soon. Or teach me how to modify a X.5 series stereo amplifier, I ,seriously, got fed up with changing power cables for fun.😎

Is it too soon to start an "Official F5 builders thread?"
Maybe just a hint Nelson? What type of PS will we need? A typical Aleph type PS, or perhaps a regulated front end? Or something like the ZV5 PS?

Well, shall we start the F5 thread and leave it blank for you to fill in when the time is right? Or invite the Pass forum regulars to speculate a bit on the topology/design philosophy? We're like children you see, cannot wait, become anxious etc...

Ultimate: something, Pure Class A, 100 watts per channel 8 ohm, doubles in 4 ohm, very best internal parts, pure copper heat sinks, .........but ofcourse in STEREO!

That's the purpose of the DIY Progress Report thread. Or at least what it has turned out to be.DocLorren said:
mert,
This is not a Pass design but could be what you are looking for,

take the 4 to 6 weeks wait and build a couple of mono block cases!
probably big with good heat sinks 🙂
then the hard part will be finished - and you'll be ready for the circuit!

i love aleph-x it sound good space bass highend every thing you name it but some time you have to change the cable................
nothing better then that a pair of aleph-x

...or not...that's a pretty complex schematic

No, it's not.
(though only worth the extensive heat combined with a <10ppm pre-amp deal)
Lovely design, but the link has no business in the PL section.
I'll take Moe's advice and start prepping a chassis for the all-JFET F-amp.
