This is not right

[Andy Bergstrom]

I built this passive preamp and just threw together this test bed in the garage. Due to COVID, the wife and I have been spending some time with friends passing time in the garage listening to this. It sounds way better than it should. What was a 2 hour experiment turned into a 3 week residency. Trying to figure out why it sounds so good? Simplicity is the highest form of art?
Thanks,
Andy

Sorry. It’s just an old Magnavox 6V6 with minor mods, a DIY passive preamp, an old Panasonic DVD player, and some QSC cinema surround speakers. All marginal stuff. I usually borrow out the Magnavox to friends to try out tubes.

What impedance is the pot in the passive? I'm guessing you put a piece of wire across each 47K resistor at the input?

It's good to see short cables between the passive and the Magnavox. You could just drill a hole in the front of the Magnavox amp and put the pot there.

Pot is a 10K. Experimented with a 50K and a 20k. This just sound so good with “average” equipment. People remark on how good it sounds. Just trying to figure out why.

Great idea on the pot in the Magnavox Paul. Just built the passive pre to use in my good stereo. This was just an experiment to make sure it worked correctly.

I really don't know why Andy. But your experlience just sounds cool: just getting into it, sharing and enjoying the tunes.
