Driving 1 ohm

The Scintilla does not need a lot of power. We drove it very easily with a set of MA-1s and a set of our Z Music autoformers (we no longer make that product, but something similar is sold under the name ZERO). Its not normally a load that you would put on a tube amp but it worked great!

I have been using a Hafler 220/ bone stock built from a kit in 1979 to drive my Acoustat 2s.
It has never been touched and sounds fantastic.
That said I would like to go the tube route and I think that it could really reveal some magic,,,,with the right amp.
I have heard and read folks talking about low impedances but I know the "nominal" load for this speaker is 6 ohms.I understand that the lowest impedances occur in the extreme high frequencies, not the bass.
Also I read that current is the key to these speakers. So can someone explain to me why a tube amp is not what I want? Also, the original Acoustats had tube amps for transformers, so there must be something there.
thanks in advance

The Acoustat 2s aren't supposed to drop below 3 ohms and only require over 50 watts. Maybe a fairly powerful tube amp will work fine with them. Hopefully you can try one before buying.
