It's worth to swap Psvane Acme 274b to Elrog 274b/5UG4?

I probably have 200 hrs on my WA22 now. The hum I reported pages ago is nearly gone. It’s of course impossible to know what changed, but some aspect of burn-in seems to have corrected it. Tubes, transformers, who knows.

As an aside, I have been re-listening to my favorite music upsampled to DSD256 in Roon played via my Qutest. Not HQplayer…just Roon over my Nucleus. Holy smokes that sounds fantasic.

I am only left to wonder what a fully balanced DAC feeding the WA22 would add, if anything detectable. I get changing the DAC substantially changes the chain but, Cyan 2 I see you.

I noticed hum on my WA-22 a week ago especially when using sensitive headphones. It was a constant hum regardless what volume I put. It doesn't bother me when I listen to music, just in between tracks or when no music was playing. Eventually I found out it was caused by my GEC 6as7g tubes. Once swap them out, the hum was gone

I upgraded my AC/IEC cable and it made a difference. It wasn't even a pricey one, but it helped a lot:

I'm running a W4S DAC 1 with balanced and RCA outs. I can't hear any difference between the two. However, I do run balanced because of common mode rejection.

I saw this on Amazon and was wondering.

Hey WA22 thread!

I have spoken with a few of you about DAC choices, and I just finished writing up a comparison of a few that would pair nicely with the WA22. Though this amp wasn’t in my comparison, its little cousin the WA2 was. Just thought I would share it here in case anyone is interested!

Really nice review.
