Speaker recommendations wanted for Quicksilver M135 amplifiers

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!

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

No disrespect but loudspeakers should be chosen by ear and then a determination should br made as to whether your amp is s good match. I don’t understand asking for loudspeaker suggestions based on a given amp. The opposite I do understand-asking for amp suggestions for a given loudspeaker. 

@decooney Unfortunatly I haven’t had much more than an hour of listening time with the Quicksilver and LRS+ pairing. It may be some time before break in is complete. Remodeling the kitchen and my listening area is currently full of new appliances awaiting install.

I lent my Mc240 to my brother to pair with his Klipsch Cornwalls. It is a nice match for sure. We listened to this combo for hours with non fatiguing joy. 

@fsonicsmith1 The situation is that the amplifiers came first. I wasn’t in the market, but the deal on them was too good to pass up. 

I have been an audio enthusiast for decades and have always enjoyed buying, selling, and repairing gear. Mostly vintage tube units. I am pleased with the Quicksilvers with the Triangles together.  Just thought I would solicit other’s opinions. Thanks to everyone once again for your responses.

Thought I would give the LRS+‘a a shot  to see what all the hoopla was about. Besides they were only $1k and I didn’t even have to get on a waiting list. My local dealer had them in stock.   I have never had an amplifier(s) that I thought was capable of dynamically driving Magnepans.
