Quicksilver Mid Mono - power matching


Looking at a pair of QS Mid Mono tube amps. It looks like they put out 40-50 watts depending on the tubes. I'm trying to figure out how much speaker I can power with these. I've heard sensitivity is an important concern and that I should be looking at speakers with 91db or more? Is that good advice? Do folks have thoughts, guidance on this?

I own the non remote linestage. If you need two outputs all you need is a y adapter. I use this when using a subwoofer. BTW, I have also owned the remote 6DJ8 linestage!

I'm no expert but I can list a couple things with confidence.
  • I love the non-remote Line Stage and have seen it for $895 used, out there.
  • Having a second out wired as decooney describes has been super helpful. My Line Stage is able to send to (a) my REL sub if I want and more importantly, (b) to another amp. Mike at QS made that mod for me for $50.
  • I've heard from multiple people that non-remote is better. Since I stream a lot, there's a volume control on the streamer, anyway.
  • I swapped tubes in the Line Stage and it pairs extremely well with a couple spare solid states I have in addition to my own QS Mono 60s.


I love QS gear.....  Mikes new headphone amp is incredible....  all Quicksilver components are a huge bang for the buck

These are what Sam Tellig (Sterophile) has and loves (his favorite amp) and because they only need 1.2v input for full power output, they only needed my Lightspeed passive pre which he uses with them, as nearly all sources will have more than 1.2v output, cd is min 2v and even phono stages are over 1v
