Acoustat model 22/2200

My thinking is with the Acoustats is that they put out only as good as they are given. The best I ever heard was a set of 2+2 with ARC tube gear. That was back in the 80s.
I don't have a tube amp but that is the way to go. I hear that the ultimate is a set of KR SETs. BIG MONEY!!!
That said I have a friend with the Dehavilland SETs that put out 50watts.We are going to try them on my model 2s soon.

Rageorge: I think your 22s are more efficient than my 2s. I would audition 100 watt tube push pulls or better still 200 watt push pulls like a ASL Hurricane which can run in triode mode over 100 watts.
Personally I have never been a Mac (amp) fan.Too expensive.Good build quality,ok sound.BIG MONEY. Better sounding gear out there for less.But if you can "steal" it for a song, go for it.

The amp you have is a excellent choice for the Spectras,you may want to upgrade what you have and put the rest in a tube preamp/phono front end. This may make for a nice combination of strength and beauty.
It all depends on what you want and what you listen to.Personally, tubes are the only way to go.

These speakers only repeat what signal they are given, so the better the signal....

Thanks everyone for your good advice. I do like my current set up but am always wondering about improvements that could be made. (FYI: my pre amp in a Lazarus Balanced Deluxe from the same era as my 22s (1990) and I have an Acoustat Spectra SPW-1 subwoofer as well.)

I'll probably take a look at the Macs just out of curiosity but I won't bite unless they're an absolute steal.

I've found a great guy here who is rebuilding my Lazarus and wonder if I should have him take a look at my Hafler also as it's been years since anyone has been inside of it. Good idea??

Rageorge: check out Musical Concepts for your Hafler. Also there are others out there that do Hafler mods. Indeed, next to the Dynaco ST70, the Haflers are the most modified amps out there.Says something for the design.Also says something about the late great David Hafler since both the Dynaco and the Haflers are his.

You don't need a monster amp, you only need a GOOD amp, Classe - Krell - Mark Levinson - Threshold - Bedini - Paslabs - Plinius - and many many more, if i was you i would stick with solid state BUT with a good tube preamp, i owned a Classe DR3-VHC & Conrad Johnson preamps premier three & premier ten for thirteen years with four different models of Acoustat's it was a match made in HEAVEN.

Acoustats have a synergistic love affair with MOSFET amps. If you want to make those panels sing in a manner you will not believe find an old Sumo Andromeda II or IIA, or better yet biamp with them. Run 1 channel to the panel and the other to a bass module or sub. Add a tube pre and heaven.
