I use a Music Reference RM-9 tube amp (KT-88) on mine. 100wc/ch in a small/medium room. Sounds great! Use the 4 ohm tap.

I'll second Elgordo's comment on the Hafler 9505. I've used one for 7 years or so with Maggie 1.5's, 1.6's and now 3.6's. Outstanding sound IMHO and excellent durability. 250wpc @8 ohms, 375wpc @4 ohms. Rave review in S'hile in '92, including Sam Tellig, and many other publications. Now sold mainly for professional use and used in many a recording studio, since Hafler has exited the consumer market. This amp deserves more recognition.
Thanks everybody. Sorry for the delayed reply. I was in an auto accident last week and have been trying to deal with the insurance company, etc.
I still didn't get a clear answer of whether a slightly lower rated (wattage) tube amp delivers the necessary voltage to drive the Acoustats or if it's strictly wattage and current that make the 1+1s go. Audiokinesis?? (Duke)
Anyway, I've contacted someone who appears to be parting with his TNT-200. I might try that first and take it from there.
Elgordo - those 9505s are hard to find. They come up very seldom and seem to go pretty quickly. Is it that much better than the TNT-200?
Plato - I like the idea of going with a tube pre and sticking with ss for amplification. I'm hearing some thickness in the midrange, particularly on female vocals, and I'm also hearing some graininess in the upper registers. I was thinking that it was probably the amp, but now I'm not so sure that it isn't the preamp. I'm using the GFP-555II preamp. I know, it sucks, but I picked it up on the cheap. In fact, my net cost (after trade) for the Adcom 555II amp and 555II preamp was $200 for both!
Add the $650 I paid for the Acoustats and $55 I paid for my Sony ES cdp, and it comes out to be a pretty nice little system for only $905!
Thanks again everyone.
I think you need lots of current for the 1 + 1s. I had a pair in the mid to late 1980s and loved them. I also used an Adcom 555 amp but also used a Janis W1 subwoofer - made a huge difference as this freed main amp from a lot of work. With a properly set up sub (I now use RELs and run main speakers full range)and cut off point at around 70-80 HZ, you should be able to use a number of amps. I would stick with SS (yet Im a tube-a-holic) with these particular speakers but would seriously consider a good tube pre-amp and even no pre-amp - go passive - Placette Audio is an excellent choice and I use one with my 300B amp.
The 1 + 1s do not have much bass and what's there does suck up a lot of current. You will have a much broader range of amp choices if you get a good subwoofer and cut off the speakers at 70-80 HZ. I think lots of current is needed more than high voltage. Good luck, these are great speakers for a large room.
