Preamp suggestion for Quicksilver M120 amps

@agranttz OP12 posts05-04-2020 6:50pmThank you guys! Just bought QS line stage non remote current version. Very exited! Now need to figure out the tube upgrade.

Congrats. Good preamp match and it will smooth out the KT150s a bit too. Maybe let the LS and it’s coupling caps burn in for a few weeks then with the stock tubes - then report how it sounds to your ears on your system with your cables, speakers. It runs a pair of 12AT7s and Mike ships them with decent tubes IE or JJ for starters... not terrible.

Based on what you want more/less of, we can get you close. You could try various vintage and a few buddies pulled their vintage tubes and tried newest version PSVANE signal tubes recently with some success. What speakers are you running again with the Mono 120s?

I am getting a used LS, should be ready to go for me. Will report back on the sound. I am running JM Labs Utopia Diva Be speakers, 89 dB.

Looking at your speakers, efficiency, and knowing the amp/preamp signature in stock and semi-upgraded form, since it's 2nd hand, def worth trying it first and see what tubes and caps are installed now. Thumbs up!  

Will report back. Greatly appreciate your help!!!

AgrantthPlease don't forget many tube preamps invert polarity and the Quicksilver  does **invert >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>simply swap the positive / Negative speaker wires at either both channels of the amps or Speakers done!>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Normal Polarity is Positive amp to positive at speakers
Normal Polarity is Negative amp to Negative at speakers**Inverted is Positive amp to Negative post at the speaker**inverted is Negative amp to Positive Post at the speaker  Best JohnnyR Quicksilver dealer
