Tube amp for "difficult" speakers,,,

Yep, its the load, impedance-wise on the 2+2's. I should have been clearer. When I talk here about driving a speaker, I tend to talk about impedance/sensitivity together, until I'm absolutely forced to talk about technicals. BTW, I still liked the MA-1s on them. Then again, I'm an SET guy these days, so dynamic compression doesn't bother me as much as most. What are those Dynaudios we are talking about here - 4 ohm load? That sounds familiar in my head.

I've got a second system with 88db (or, 89, I can't remember) sensitive LS3/5A's, but they are 15 ohms, so I can run them quite well with an Air Tight 300B 10W amp. You wouldn't think so, but its works quite well. No head-banging, but its not meant to be that way, can't be.

Anyway, 83db/4ohm speakers I think are going to suck up some serious real estate. To be honest, I think someone you wants those types of speakers should go for a Pass 200 watter and be happy that that's as close as he's going to get to SET, or OTL, mids, spacial rendition and harmonics.

I assume the sans-ZERO MA-1s could do the job, but, then again, he's coming off of 600W of Krell...

Hey, o Holter, what do you say about some big OTL's? Ralph Karsten is here and he's the man...OK, I'm changing my mind...anyone who has Krell on a 83db speaker and wants to go SET MUST be willing to get into the deep end, right?

Ralph, I hope I just helped you with a sale!

I am on holiday and not able to follow this thread so often, so this is just to say, thanks for more advice and suggestions, and also: I use the Aesthetix Io, so I am not exactly new to tubes.

O holter, understood. My apologies. So, then, what about that MA-1?!

They're no longer made, but you might look for a Mesa Baron. Here's one available on eBay.

A couple of years ago I heard two models of Dynaudios large floor standing speakers driven with ease by VTL 450 monos.

On other occasions, Dynaudio Temptation were driven by the superb Atma-Sphere MA-1s.

The Atma-Spheres, VTL and Sim audios Rock solid state amps were a very good match driving Dynaudio speakers.

I would like to add ,I purchased a pair of Dynaudio Special Anniversary 25s in 2004 to use as a second pair of speakers in my system.
I found the Atma-Sphere M60 MK11 monos a thrilling match for the speakers. Even the 30 watt Atma-Sphere amp drove them with no noticeable problems.

For sure I prefer tube amps driving Dynaudio speakers.
If you are going to keep your currant speakers, perhaps try the VTL 750

I have listened to the Temptation on a few occasions and have seriously considered them at one time, a used pair however.

O holter, this may sound crazy for the price difference, however it is for real.

For a fraction of the price the Canadian Grand Veena Reference 3A speakers is a must listen.

Right now I am in the city where the 3As are made. I have listened to them ....Absolutely stunning for the price.

What I heard, I like them better then the Temptations including a few other expensive brands on my shopping list.
