I'm a bit of an audio doofus, so I would appreciate some expert advice on the particulars of my variant of the Lampizator gain issue.
I have a Lampizator GG v1, and I recently swapped in a new integrated amp . I'm now using a Pass Labs Int-60 and I immediately encountered what appear to be fairly common problems with static and distortion. After asking the folks at Pass, I was advised to try a 6db in-line RCA attenuator. As a short-term fix, it definitely worked, and the noise is now gone, but I'd like to get some input on a more permanent solution. I'm open to swapping out the GG for a model with low gain/volume control or getting a power amp instead of an integrated, or just adding a passive preamp to my existing chain.
A couple caveats: I live in an older apartment building that's not grounded, so wondering if I need to factor that into any possible solutions with the excess DAC voltage Also, I have pretty painful fatigue issues and so I don't want to add anything to the chain that will be too bright or forward.
1) Amplifier: Pass Labs Int-60
2) Music server/renderer: Antipodes CX + EX;
3) DAC: Lampizator Golden Gate V1(R2R); single-ended, no volume control; Tubes: KR PX25; EML 274B
4) Speakers: Verity Amadis S
Thanks for your assistance!
