I concur. Get low ppm Caddock IMO, or PRP 9372 TC50
More resistance @ tx instruments, more costs.

Hi. I replaced all my signal path PRP resistors with Caddock 132's in the 1m
position, TF020's in the 220k position and TX2575 in the 220R position. The
sound is a lot smoother and detailed and the imaging improved a bit. As Dart
Vader used to say: "most impressive"!

Currently I have Nichicon FX 4700uf and KZ 100uf capacitors installed. Will
replacing any of these with "better" improve the sound much? I thought of
replacing the 4700uf's with Nichicon KZ Gold or Mundorf MLytic AGs? The Nichicon's
arent too expensive, but the Mundorfs are.

Would it be worthwhile to replace the KZ's with Elna Cerafines?

Mundorfs are simply the best caps you can use there but if they're too costly don't worry much about it...

IMHO yes but the best thing you can do is to try...Cerafines have reasonable cost.

Did you up the bias beyond 200ma? That brought imaging up substaintially in my setup, which looks a lot like yours now. Some day I will go for the Mundorf's - if for nothing more than to express what I think of them for the masses.

The 100UF KZ vs the ELNA's is a good one. slightly different tonal charachter. Elna smoother, and Muse sharper. Get both and solder in just the leads a bit, and try them out. Of course the Elna's certainly like a lot of back in time so consider that. Leave it running for a few weeks.

Enjoy!!!

I have some Sikorels on the way that i will pit against the Nichicon KG. I also will be trying PRP. If i can tell a difference over Kiwame, i will go for Tx2575.

nice work on the enclosure Evan, you really should make yourself an LOD for the ipad to replace that mini2mini. if you need instructions or a dock connector let me know i'll send one to you. ive started working on mine again for a bit of fun, mainly to use up some tx220 in 4R i have acquired an abundance of and also because ive stuffed it with such premium parts it would be a shame to not use it before deciding whether or not to flip it on. as ive said before, i dont really need a buffer, but its such a cool OTT design

Cool way to mount it in a wooden board. Nice. Big speakers, efficient doublets I suppose. What is the voltage gain of the amp and the speakers SPL/1W? Is the volume range practical with a buffer?
