    NAD 3020i driving capability

    Thanks, Gasolin. Today I went out and bought a set of cables similar to those you posted above. Convertion, too, to 110 v, has been a simple task. (I didn't know there's a fifth rubber foot inside the case, fixed with glue under the transformer.) As for the question...

    NAD 3020i driving capability

    Hi, My first post at What Hi Fi? (2020) was followed by very useful suggestions, so I'm here again for some light on this impedance issue concerning the NAD 3020 amplifier, specifically the "i" version. I've just received a second hand NAD 3020i amplifier, bought online. It's in excellent...

    An issue with vintage amplifiers

    Belated thanks to those who helped with suggestions. Distortion issue was solved with the DAC and the attenuators. Distortion virtually disappeared when I connected the CDP to the DAC (Soundavo HP-DAC1) via a toslink cable, no sign of overload appearing on the DAC's clip LED. The same didn't...

    These I've discovered right here on the thread.

    An issue with vintage amplifiers

    (y) There's this thread of communication with unknown and distant people, and all of a sudden listening to music is a fresh experience to me.

    An issue with vintage amplifiers

    Thanks everybody, it's been very instructive. The CD player is a Sony M27 (1989! Not much used and still working). If the DAC shouldn't eliminate all the noise, next step will be the attenuators. I'll discuss the matter with a friend who builds his own amps and pre-amps, and upgrades old ones.

    An issue with vintage amplifiers

    Thank you for answering, 12th Monkey. That's it, distortion occurs mostly on louder passages. I've noticed it first on some mellotron laden Moody Blues passages. The same problem doesn't happen on my more modern amps, less powerfull than the older ones, and with less input sensitivity. (But I...

    An issue with vintage amplifiers

    An issue occurs when I hear music from the CD player through my older amps (from the mid-70s). It's a kind of distortion on certain snatches (not the whole records), as if those passages are partially saturated with sound. (Sorry, it's not easy for me to describe it in English.) The same CDs...
