@decooney I am running NOS RFT EL34’s biased at 40ma. 12AU7’s are RCA clear tops and 12FQ7’s are RCA as well.
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 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! |
One reason for that @decooney is that the ET’s have a relatively high modulus of impedance. If you bi-amp the LFT’s, the planar-magnetic panel itself is an almost purely-resistive 11 ohm load. Maggies on the other hand are nominally 4 ohms, dropping to 2 ohms at some frequencies. Tubes don’t like low impedances. By the way, one of the few of his contemporaries Roger Modjeski respected and saw eye-to-eye with was Mike Sanders of Quicksilver Audio. Another was Tim de Paravicini of EAR-Yoshino. But then Roger was known to be somewhat ornery ;-) . Both Maggies and ET’s are very low-sensitivity designs (low-to-mid 80’s), but as with all dipole planars that measurement ignores the back wave of the loudspeaker, half of their output! |
