Tube-amp for Magnepan?

Guys, in living with a strong willed and regal female German Shepherd (I won't go into the lineage here), I understand the German thing.

For what it is worth I run Manley 250 W mono's with my Maggie 3.6. The tubes are Electro-harmonix 6CA7. I believe I have a wonderful warm sound, with an incredible sound stage especially its depth. As tube amps go, these have more than enough power to get down to the 34 Hertz the Maggies are rated. Enjoy your search.

I used my Tad 1000 monos (sadly no longer available) on "Gunned" 1.6's and SMGA's and the results were outstanding, even John, aka Peter Gunn oddly enough thought the bass from the Tad's sounded better than his Pass 250 The 1000's are rated at 100 wpc but have excellent dynamic range and wouldn't hesitate using them with maggies

I also run Manley mono 250s with my 20.1s. Using SED Winged C EL34s, Marconi-Osram A2900s and RCA black longplate 12BH7s. Don't have any trouble with bass extension and with my tube preamp have been able to dial in a just-the-other-side-of-neutral warm sound....the way I like it.

I lived with a pair of highly modified MG IIIA's for many years, and tried many different amps with them, both ss and tubed. I always returned to tubes, and settled on Manley 200's, which I use to this day (with different speakers). For me, the issue was always one of excessive leanness with ss amps. Only tubes would make the speakers sound dimensional enough, and with enough fullness to sound realistic. But when they did, they sounded glorious. The other issue was that ss amps, regardless of pedigree, made worse the Maggie's main flaw (for me). That is, the obvious discontinuity between the ribbon tweeter, and the planar midrange. With ss, the ribbon's superior speed and resolution was laid bare, and became an annoyance. With tubes, there was much better integration of the two different frequency ranges. I always preferred the handling of dynamics with tubes.

MG II's don't have a ribbon tweeter, so continuity between tweeter and mid will be, in theory, better. A good modern ss amp might give you a needed sense of clarity in the very top end, but I doubt that you will be able to get the kind of dimensionality that a good tube amp will. My Manley's put out 100 watts in triode, and it was pleny of power. Good luck.
