Atma-sphere M60 II.3-Any good for 4 ohm speaker?

711smilin, against conventional wisdom, my Atmas have sounded great with a 4 ohm speaker - Frieds. Actually, they are the best amps I have come across for Frieds.

Now, understand that the series crossover (presenting a resitive load) might be the reason, but since your sensitivity is high enough, you might want to give it a shot. The other thing is that a lot of loudspeakers specify a nominal impedance of say, 8 ohms, but the actual curve shows them to be quite demanding. I hear the Reimers are a kind load to an amplifier.

Incidentally, have you bought a pair of Atmas yet? I have an ultra modified pair that I might be able to give you a really good deal on (not yet sure that I was going to sell them). They are MKII.3, plus A LOT of upgrades, such as the 12SX7 (instead of 6SN7 driver - better than any 6SN7), and some other unique things.

Trelja, I have not bought them yet, I was thinking of buying the pair for the tsunami auction, for a good cause, and a write off. Email me about yours if you would. I just sold my pair of cardinals, and received the DK today. I also have my VRD's kt88 mono's. But am obsessive with this journey. Call me an audiophool, if you will. I do.

711smilin, I might be the guy you should be talkin' to :-)

Brian, good suggestion, why did I not think of it.

Can anyone tell me the difference between the new Rendition Audio Monitor 60 and, the Atmasphere M60?

The Monitor 60 is one beautiful piece. I am assuming both these amps were designed by Ralph.

711, an auto-transformer will solve the 4-ohm issue. I used an Atmasphere MA-1 on my Magnepan 3.6's with the auto-transformer with excellent results.

But that Monitor 60.......it sure is nice looking....
