Tubes for Magnepan’s.


I think next up on my acquisition list is a tube amplifier. I'm not looking for the be all end all, cause I don’t think there is a definitive "Best", so am looking for as good as I can get for $3-4k.


Because tubes drive speakers so much more efficiently than solid state I am only looking for 40-50 watts to drive my modded Maggie’s, 1.7i's. (Or what you have when you add a new crossover and planer tweeters to 1.7i's.) Maybe 2.7x? I haven’t settled on that yet. And I have some Zu Dirty Weekend's upgraded to the max coming in in 2 months to replace my KEF's.

Anyway, I haven’t had a tube device since my Halicrafter short wave radio, and reviews are not the same as advice from people that own something. There is a Rouge Audio dealer in my area, last I looked, (opps, they no longer carry them), so I may have to go to another market to hear something, or get a try before you buy from a manufacturer or dealer.

You folks have taught me a lot, and I think asking users is the right thing to do on this change in direction.

Thanks in advance.

not to be argumentative here, let’s put this issue in perspective

maggies are a flat panel speaker, low impedance, resistive load (not highly reactive) - different models run big and small, they differ in how they need to be driven... in the bass frequencies they need significant current drive to move the panels, move air, develop even a modest sense of drive and ’slam’

no doubt up the frequency range, they are exceptionally pure, and not hard to drive - thus if not asked to play loud and develop a convincing bottom end, tubes can sound utterly wonderful

the critical issue here what is needed to get the bass drive and slam out of maggies (make the speaker move alot of air in a hurry) this is the key weakness of the maggies and needs to be dealt with ... so, typically very good systems with large maggies owned by tube amp lovers use serious upper end tube amps (pricey and run very hot, burns through tubes - think vt200’s or big vtls, that league of tube amp)

the issue here in this post is the OP posted he is ’getting into tube amps’ and has a budget of $3-4 grand... so given that, i say, stick with good solid state at that price level -- for example a $3000 hegel h190 or h360 will properly drive a set of m 1.7’s top to bottom much better than a $3000 tube amp imo -- at proper listening levels and with proper bass response

maybe a higher powered primaluna tube amp with 8 power tubes can be had used for $3000 (eg dialogue premium hp, for instance), but of course, that amp has tube-i-ness in spades but not the best resolution/transparency.... perhaps an older vt100-2 at 3 grand would be better top to bottom, but even with its 4 ohm taps, the bass response will not as solid, deep, controlled and taut as if driven by a hegel

my 2 cents

We have already settled on a tube pre into a SS amp, I think. 

But thanks so much for you detailed response. I want to buy a used A23 just to gauge the difference between the Parasound Halo line and my Benchmark AHB2. I can always use that in my studio, since my Adcom 555 is dying.

I was thinking a Parasound A21 or a Hegel 20 or 390 used for a high current amp.

Let there be Peace in this valley.... 😉
Have you tried a Sunfire Signature amp on them? Among the best sound I ever squeezed from MG 20.1’s and reasonably priced.
