Running headphones out of my DAC's pre-out using an RCA -> 3.5 mm female adapter. This... sounds good. Sep 6, 2022

        Are you using high impedance headphones?

        Singxer sda-2 (10 ohm output impedance), and I’m using phones ranging from 32 ohms to 300 ohms. The iFi Gryphon (100 ohm output impedance) is also good with 300 ohm headphones and IEMs.

        All dynamics (hd650, ms-pro, es-r10, aliexpress r10 clone) of course, no planars.

      The Fiio FD7 might be the most plankton-rich earphones I've ever heard.

      Hmm... the vali 2+ is actually a rather nice preamp if you use the headphone out instead of the preamp out (which is really mushy sounding)

        Preamp into what exactly?

        Another tube amp (3-stage 45 PP). It has its own volume pots (highly inconvenient dual mono "stepped" pots), and for whatever reason, it did not like having the Sys in front of it either. Then again, neither did the Magni 1.

        Ok, I have definitely exaggerated the differences. However, I still detect a decrease in bass definition and softened treble from the preouts (but not with a very high level of certainty... and I'm tired of AB-ing). Would be nice to have more data points.

      Just realized that putting two pots in series really fucks with your sound, even if one of them is maxed out, at least with a 1k ohm source.

        I'm following @atomicbob's SOP of passive attenuator and amp pot set at unity gain. Does this count as 2 pots in series? Maybe it's anti-synergy of the source and pot impedances.

        @crenca significant loss of detail and immediacy. Having a Sys between the parasound dac2000 and magni/45 tube amp significantly worsened their sound. I first noticed this with the Magni, actually.

        Although cable length is a possible confounder, the setup with Sys had 1 m cables, while the setup without has a 2 m cable.

        @gixxerwimp Yeah, its possible that lower impedance sources won't be quite as badly affected. The Theta Gen VA (which happens to be available locally...) with its 1 ohm output impedance probably wouldn't care as much.

        The setup you described is exactly how I had previously configured my own setup. The dual mono pots on my amp are such a pain in the ass to use.

      Have replaced the motorolas on my Pioneer M22 with original Sankens. Slightly less bass, but feels more "real". Harmonics sound nicer too.

      I have a 45 push pull with ef86(triode)+6cg7. Would 6CG7+6H30 work with 3A on the 6.3V supply, and will it increase open loop LF response?
      1. Tachikoma
        Tachikoma
        ... the need for more open loop LF may have been alleviated by swapping in a pair of Shuguang CV-181Z from my stash. Still rolls at 20 Hz without feedback but wtf is this bass. Anyway, the answer to my question seems to be "nope", much too close to the max rating.

      Head-case has been down for a few days now. I know most people here don't like them very much, but its still a bit of a loss.

        Yes, I was eagerly waiting Kerry's take on the CFA3. I hope they survive.

        I was checking periodically. It's working again.

      I got a 45pp amp, but it won't fit EML45s (only 5cm between the center of each tube socket). Can I tilt one of the sockets to make room? >_>

      If anyone has ever wondered, yes, the Pioneer M22 is quiet enough to run Grados.

        Also, the MS-Pro scales surprisingly well with amping. Wasn't sure it was a keeper until I had done this.

      If you own a pair of Stax SR-003s, find an old pair of foamies, rip out the inner jacket and stretch them over the tips.

      Auditioned a few chifi IEMs on a whim. TFZ No.3 Ti: disappointing, Fiio FA7: bad, Fiio FH7: I might like this better than the ier-z1r
