    DAC rec for H/K AVR 70 (1996)?

    Hi, I have a 1996-era Harman/Kardon AVR 70. All RCA. No HDMI, no optical in's. My Panasonic TV only has optical audio out; what is a good DAC to use?

    Hi there - first post! Recently, I bought a Harmon Kardon 330C as part of a vinyl system that I'm setting up for myself. I have the opportunity to buy MB Quart 280s for a little over a hundred, and am considering it. Not sure if it will work, though. The receiver outputs 20 watts per channel -...

    DC Offset Issues - Harmon Kardon HK580i

    Struggled for several weeks off and on with an HK580i that had 6.7-7.0 VDC at the speaker terminals on one channel and neither the Offset or the Bias POTS had much effect. Issue was the OEM glue on the back of the Amp board holding down C431 (electrolytic). Over the years the glue had...
