      Just finished restoring an old Onkyo A7 for shits’n’giggles. Not bad, actually.

      All harmonics on Pioneer M22 were below the dynamic range of my HP analyzer. Just bought QA401 to go fishing with more bit depth

        Hardly surprising. Which HP ?

        HP3561A. It has a nice noise floor several dB below its -120dBV (1uV) spec, floating ground, and is capable of handling full power amp output up to 22V RMS without extra attenuators, but it’s buit on a 13-bit DAC, so the dynamic range is limited to 80dB.

      After 3 months of detailed rebuilding, careful component matching, and design edits, my Pioneer M22 is singing beautifully.

        Can you detail this in a forum post, or link to where you have? I'm interested to read.

        So I have determined m22 is still not ready for prime time. It’s good, but my pass labs is cleaner so I’m going to do more work on the m22. Stay tuned.

        Oh, that's hat you have to do to post there?

        Reading that site is so painful that my account has only managed to make it to 3 posts after two months. Don't even bother checking the sales forum there anymore.

        Yup. But since the trolls just challenge you on every point, it's easy to just reply to them with some factual information. I even managed to saturate my troll to the point where it shut up. Small victories.

        Maybe whoever set it got confused with the DC balance, which is 80mV

        Yeah, I wanted to keep it but I *know* I’ll be dropping it. My SE has survived over a dozen drops. I seriously think the X & 8 designs are a scam by Apple to extract revenue.

        The thing is that the back glass is so much grippier than the aluminum is. I never got used to the size of the 6 and the instant the SE came out I switched, had that till the X launched. Even though the C is bigger than the six was, it’s size never bothers me

    I like a laid back, detailed/textured sound that is not fatiguing. I listen primarily to older jazz, piano trio, bebop, and classical. Sucker for a bit of warm tonality provided it doesn’t screw up timbre too much.
