Speaker recommendations wanted for Quicksilver M135 amplifiers


Hello All!

I just acquired a pair of Quicksilver M135 amplifiers and line preamplifier. I wasn’t in the market, but they came to me in a trade. I am wanting everyone’s recommendations on speakers new/used under $5000. Room is 16x22, however I listen from about 7 feet away. Music preference is jazz and some light classic rock.
 

My current system consist of a McIntosh 240, Fisher CX-2, and Triangle Comete 40th anniversary speakers. 
‘Thank you in Advance,

Rob

@thermionicemission Rob, your current TC Anniversary shows 8ohm nominal impedance and 90db, how about trying those first?  You mentioned listening 7' away, might be worth a first try, see how it goes, 'eh?

Vandersteen Model 5, 5A were paired up some times with the QS MX-135 amps years back, and forward. Said to be "consequently, can be driven by a mid-power amplifier despite its modest sensitivity of 87db". Also helped by its built-in sub, etc. Worth looking into even if they are older and require some type of refresh, updates - considering the desired price range. As recommended, check with Johnny R.

I've seen MX-135s on sold years later at my local dealer, and discussion around driving various electrostat speakers there too. Some transformers in them, fwiw.  

 

 

@sutts If you ever decide to sell the M135 monos please let me know- thanks!

Hey, "Get in the back and form a line" as they say.  Just kidding. 🤣 Some of the bigger QS amps have become somewhat collectible. The M135s are unique and desirable to some in their own way. Then came V4s, and Mono 120s, now becoming more unobtanium too. Maybe check over on the Quicksilver Facebook group, more  Some QS folks hanging out there too. 

 

@thermionicemission  are your MX135s running the KT88s or EL34 output tubes? If so, which ones. Originally I believe they came with EH KT88s. Can taylor the sound some from there or with the smaller 12FQ7, 12AU7s if you choose. Good sample of different type speakers you have there too, should be fun. Enjoy! 

@thermionicemission nice setup and choices for tubes. I’m a huge EL34 fan myself, in the right amp with good transformers. Curious to know what you think of this particular M135/tube setup now - compared to your MC240. Which is simply more engaging to sit and listen to music for longer listening sessions, and why?

+1 @bdp24 i've actually heard both the LFT-8b and LFT-16a speakers through various older generation and recently new Quicksilver amps at my local dealer multiple times. Interesting how the ETs are very low efficiency yet the QS-ET combo sounds very nice together. Heard them with my QS M120s too, very nice!   

@thermionicemission how are those Magnepan LRS speakers coming along paired up with the Quicksilver M135 amps?
