Mani, did you have a chance to listen to some good quality Tripaths (t-amps)?
No tripath chip is able to power his electrostatics. Hmm, even Virtue Sensation? (65W per channel) I guess you know better, I haven't got any contact with electrostatics so far. I wonder though, how come you prefer the old Pass integrated amp considering what you wrote about Hypex Just curious..

I know of a company who just put into production a linear PSU at the size of a matchbox, especially made for PCs (ATX connections). No fan in that matchbox as well, hahaha.
I am not sure it is too early to tell about though, and I don't think they have a sales channel for it yet. But since I am a customer there already ... who knows. The price is (don't laugh) around a 100 euro. The "inventor" of it is an audio freak himself ...
I don't know how good it really is, as I didn't have it in my hands myself. IIRC 5Amps can be drawn from it.
That's great news!!! Update us if you find out more pedal, you could always buy a Pico PSU and feed both, p4 and p24 with the linear psu like Peaktech 6080 through the pico psu. It's very easy to implement and quite cheap as well. I would probably go with Pico+Peaktech combo myself unless Peter reveals some revelations about linear ATX psu available soon

Peter, you know, I've found the culprit of that mysterious buffer problems. Windows changed power settings without a notice although my power plan was still set to performance! I had to change to power saver and then back to performance again. Stupid, but that did the trick. I've been experimenting more with number of activated cores and discovered another mystery. With 2 cores enabled OS' performance is somewhat better - apps load faster and dpc latency is about 20% lower in comparison to 4 cores. I don't know whether it's a system issue or my platform's rather. Anyway, one core sounds the best and I am able to achieve the same buffer sizes regardless of sample rate used. I also added a second PSU for 4P socket and all the dirty components (hdd's). My primary (better) PSU supplies 24P socket only - very good improvement, but that's just the beggining of my pc-audio trip. Dedicated super efficient audio server with linear power supplies to come...

Peter, I get your point and totally agree with you, but assuming my PC "lives", I can't control it or predict its behaviour for sure. That's why PC audio is so complicated. Another funny thing, now that's everything is back to normal (in my opinion), I like invert more. And all my findings are backed up by my girlfriend and she knows when sth is right Have a nice weekend! Marcin

Maybe a little extra tweeking and maybe let John Kenny do some surgery on the hiFace and you'll never hear from me again! This trip never ends..., Remember me writing about buffer sizes and losing my rabbit? Guess what? After I deleted XXHE config files, made a clean install, I'm able to listen at 1024 samples again!!! Why? What happened? Peter would probably say - your PC is faster- but no, it's not faster, I got 4 apps running, 40 tabs in Firefox open and my dpc latency varies from 200-350us. Maybe to low os latency doesn't allow for low buffer sizes with my drivers? That's magic for me. I won't reboot ever, afraid that my rabbit'd run to hole and I won't catch it again... The sound is 100x better now. Again - why???

I haven't stopped playback nor quit app normally before rebooting my PC and that's what happened after the restart. I am welcomed with these "pleasent" messages. What now? I can't start XXHE, so I can't listen to music ;/ Tried fresh installations (z, za, zb) - nothing changes. Installing elsewhere doesn't help plus I get a "demo version" popup before errors appear.
I'd appreciate your help asap Peter,
Cheers, Marcin
