The Wire is certainly a very fine amp indeed, got say that I swapped op-amps and output caps on my source after logging about 50hrs on the Wire. Each change to the source has been clearly audioble, both good and bad... Super happy with the Wire

Was very tempted by the LPUHP amp, but the only spair speakers I have are 25W / 8Ohm... looking forward to whatever opc offers-up next.

Regards,

Paul

Owen, can you post BAL-BAL measurements? I have shoveled the thread but found only BAL-SE and SE-SE. Just curious to see fully BAL.

Op-amps: from JRC5532D to LME49720MA.

Electrolytic caps: from Elna Tonerex to Elna Silmic II, Cerafine and now Nichicon KZ.


Now wondering about bypassing the caps!? More research & questions to ask about this...

Anyway, it's all fun. I can disassemble, swap caps and rebuild the player in well under an hour now

I'm only just about to start procurement of parts for my bal-se but you might be interested in some of the posts in this thread from late Dec around this very issue - "The Wire" Ultra-High Performance Headphone Amplifier - PCB's

Cheers for the link, it answers part of my question

Was looking on LC Audio's site [XO3 clock] and they list other possible upgrades, bypassing the output caps being one. Looks easy enough to do & normally I ask the 'why & is it dangerous' bits after the doing part. This time I'd like to know what the bypass does [how & why it works] & can implementing it be harmfull, before doing the mod

Paul.

p.s. I wasn't looking to remove the caps [directly coupling the outputs?], but adding a bypass cap & resistor. Probably easier to directly couple the outputs though...
