Hello,

I know and love that the M80V2s suck mega watts of power in the
pursuit of that real sound. Occasionally I get wistful for
the vaguely remembered warmth of those old 70's tube amps.
As a qualified non-expert I thought a tube friendly speaker
would have a relatively stable, high impedance curve, not
dipping much below 3-4 ohms. Our beloved M80s do not fit this
criteria. Anyone have experience with a tube amp M80 combo?

Thanks,

PB

They don't dip much below 4 ohms, so they might work.

They're pretty darn efficient, too.

Why do you think the m80s would not fit this bill, have you looked at the graph?

I tried my M80s with a tube amp from a local dealer who came over to demo a few years ago and they sounded great. I love the sound of detailed speakers combined with a tube amp for acoustical music or most music with a lot of ambience. A tube amp alone wouldn’t IMO cut it for movies but for the music I demoed (Bliss - Quiet letters, Rodrigo y Gabriela, Buddhabar - Chill out in Paris) it rocked. I wish I had the M22s at the time since I feel they actually do a little better in the midrange and the highs than the M80s and would even have sounded better.

PB, there's no apparent good reason these days to resort to an obsolescent technology such as tube amplification. Be that as it may, the M80s certainly don't "suck mega watts of power" but in fact are slightly more sensitive than average and require less power. They also have a relatively smooth impedance curve varying between 4 and 14 ohms, with perhaps a 6ohm overall average.

Sir Quack,

I have a healthy respect for my lack of expertise. Hence the
inquiry as to who may have actual experience with the M80V2
tube amp combo. I was intrigued by the back and forth with
audiosavant and the respected elders of this site. Please
enlighten me. What doth the impedence graph imply?

Gracias

PB.

John K.,

I get it. But some deluded simpletons like that distortion
induced warmth from tubesville. Hence the question.

Respectively,

PB.

A correctly designed amplifier, regardless of its output devices, exhibits no "distortion induced warmth" when operated within its designed limits.

Do you already have M80s, PB? Couldn't hurt to try 'em out with a tube amp. Me, I'd probably head more towards a higher powered tube amp (but I know those are godawful expensive). If you keep the volume relatively low, I think you'd be ok.

Having never really heard a tube amp, I can't say whether I'd enjoy the even order distortion. More power to those of you who do! (especially when you admit it's even order distortion...)
