Suggestion for Amp to 2 ohm loads?

Look, first of all the 2 ohm load is more than likely in a very narrow frequency range. I don't know of any speakers that are nominally rated at 2 ohms. Secondly, the sensitivity (efficiency, if you like) is another consideration. Thirdly, the phase angle of a speaker should be another consideration. Some other posts mention room acoustics, etc. So it seems it is not such a simple answer.
Of course, you could always by some brute force amp and probably not concern yourself.

My own experience is using 60w tube amps to drive Acoustats and Magnapans to very satisfying levels.

The speaker mfg certainly could suggest the best type of amp, but any good amp that is rated for 4 ohm loads will probably work just fine.

If 2ohms are in the common spectrum for yr speakers, I would make sure my amp is optimised down to about 1ohm (see garfish above) or go with products that take low loads into account; Symphonic Line RG4 is one such product (see Rulee, above). Of course, you need to like the sound too!

If 400 watts into 2 ohms would work for you, a CODA Continuum Stage+ amp would be an excellent choice. It's stable into fractions of one ohm. Has powerful, tight bass and great delicacy in the mids and highs, too. See this site for more info:

pass x250.

The McCormack is nice as Craig suggests. I would add the Sim Moon W5 and the Blue Circle BC26.
