Wow this thing is amazing just initial impressions are the soundstage opening up quite a bit. Wonder how it will sound with more time

That's odd.. Mine keeps fluctuating. I'll continue looking for the source of the problem.. Maybe it's the DAC chip that's faulty?

also, what do you mean by 'gone through the reset buttons"?

which direction should i use to solder the Silver mica caps, to headphone amp? They are substitution for the snipped one near the opamps.

richard, your HDAM position seems ok! I had mine in similar position. But you might want to secure the HDAM properly with cable tie,in case it slide off the board and short on the chasis. Try not to use flammable material, it kill all the bass..... just kidding, it's just simply safety concern.

Since I'm in Taiwan now,today, I've got many fanciful caps from almost the entire common caps range( except Blackgate) to try out to mix-n-match to get the sound i like. ANy recommendation for thick, warmer mid vocal, current treble is too sharp and plenty of peak.

Shrink Wrap

Does anyone know where I can get the proper sized shrink wrap for the green russian caps? I'm located in CT USA.
What size shrink wrap is it?

Would it be worth while replacing all those capacitors labelled 100n100v (0.1uF 100V) (the little yellow ones) in the headamp section around the opamps, and around the DAC, with the equivilent of Wima MKS02?

Well, it should be ok to replaced with the red wimas.
imho, i think the main thing is to do up the franken mod first, any other fanciful stuff can come later.

Do I need to solder the caps from the top and the bottom of the board? If so then why does the original caps only have solder from the bottom of the board?

Thanks

Wow good work guys...the SQ's just get better and better past 150 hours. It's really a whole new ball game after the mod with the stock unit sounding rather bad by comparison. No BS, honest

Peete.

PS Love the Stealth Paint Job. Is that just flat black enamel (spray can) ? Did you have to rough up the front plate a little to get a good stick with the paint ?

prinz they are non polarized like the PIO and yellow box caps. Doesn't matter which way to install them.

I wouldn't bother...those yellow EROS caps sound better than the WIMA's IMO.

Elna Cerafine or Silmic are the ticket. BG are very detailed and Neutral.
