"Thanks for update. How do they sound at low volume?"
My tube amps underwent a major upgrade recently, one of the goals was to enhance low volume speaker performance, among other things.
The .7's sound pretty darn amazing at low volume now. And I mean LOW. At moderate volume, the improvement over the "old amps" (which were excellent) is extraordinary. The most apt single word for the sound I'm hearing now is "effortless."
I've got a pair of Sonus Faber Cremona Auditor M's which I'll hook up in a week or so.
The amps are MFA M120's which I've had for many years and which have undergone one moderate, and now a major upgrade. Also, FYI, my preamp is a highly-upgraded MFA Luminescence.
I added a pair of Magnepan DWM bass panels. I run the panels and mains off the amps, meaning I don't use the "high out" on the panels.
The bass panels are placed about a foot in front of the .7's and against the side walls. Works great for me. Sound is much fuller and the DWM's blend seamlessly.
If you’re not married to the idea of Magnepans, look into the Eminent Technology LFT-8b. It too is a planar-magnetic, but while the smaller Maggies are single-ended (magnets on only one side of the Mylar), the ET’s are push-pull, which affords lower distortion (as low as an ESL). Maggie driver voice coils are wires glued onto the Mylar, ET’s m-p midrange driver (which covers 180Hz to 10kHz, with no x/o!) has a layer of vapor-deposited conductive film sprayed on it’s Mylar, resulting in much lower moving mass. The ET has a ribbon tweeter, and an 8" sealed dynamic woofer. The LFT-8b plays considerably louder than the smaller Maggies, and on less power. The ET likes a tube power amp (it is an 8 ohm load, 100w/ch is enough), the Maggies solid state power (a 4 ohm load needing as much power as you can afford).
The LFT-8b retails for $2499 (an absurd bargain, which may be why it is not taken more seriously), but can occasionally be had for $1500 used. So there is no misunderstanding, I love Maggies, buying my first pair in 1972. I now own a pair of the Tympani-IVa’s, and just heard the world premiere demo of the new 30.7, the updated, contemporary incarnation of the T-IVa. If there is an Eminent Technology dealer within driving distance of you, do yourself a huge favor and give a listen to the LFT-8b, the speaker VPI’s Harry Weisfeld says has the best midrange he has ever heard, regardless of price.
