Atma-Sphere M60 or David Berning ZH270?

Hi, fellas:

I apologize for answering this thread late due to busy and laziness. Here are my impressions of the amplifier and Coincident SE:

I think they are very good synergy at least in my environment. I don’t have much experience with varieties of amplifiers to try, but so far I have been very impressed with the sound of this combination.

The Berning ZH-270 seems to possess strength from both world of solid state and tube amplifier without their weakness. To me, it seems to remove a veil between the sources and your ears. It’s clean and clear as those good solid state amps do yet retains the harmonic richness of a tube amp. It makes musical instruments more life-like and less artificial. The high frequencies are clean and smooth and the lows are ample without exaggeration. Listen to the opening movement of the symphony no 7 by Mahler (Tennsted/LPO/Angel LP). The sound of the tenor horn has body and weight yet rich and smooth and the sound clearly comes from right and rear corner of the orchestra. The mid are rich and smooth too as demonstrated on violin/fortepiano by Luca/Bilson playing the Mozart’s violin sonatas (Nonsuch LP). You can clearly hear the musicians breathing of beginning of a phrase as in Mozart B-flat string quartet (Amadeus/DGG LP) or breathing between movements/CD tracks of a piano sonata (Brendel’s Beethoven sonatas Philip CD). I can listen to ZH270 and Coincident SE for a long time without listening fatigue.

Again, I'm very impressed with these two combination.

Thank you for your observations Laoyuap, I'm glad you are happy with the synergy and the sound. I find my Atma-Sphere and Coincident combo to be very much as you described your setup with the Berning in terms of the musicality. Cheers!

This is a great thread! I'm also looking at the Berning vs. M60 choice for Coincident speakers. The high impedence of the Coincidents looks like a natural for the M60's, so I'm glad to hear some positive experiences there.

Another choice that has just come on my radar screen is Bruce Rosenblit's new OTL design, the Transcendent Sounds BEAST, only available as a kit for about $3700.

I'm a OTL believer, altho I've got a few transformer tube amps around too. Right now, in my upstairs system, I'm using the Transcendent T8 OTL with a pair of North Creek Eska speakers, with an impedence "twister" that keeps them around 7.8 ohms, plus/minus 2. These make very nice music, especially believeable on small-scale chamber music, male vocalists and ensemble groups/folk music.

When my Coincidents arrive, I expect they'll be much more efficient, but I'm still looking to upgrade to a higher-power OTL, and I hear the M60 calling my name. So thanks for all who shared perspectives on this thread! Happy ears!

i always believed janson caps to be the best caps you can,
buy except the ultra expense durland mega caps at over $1,000,
each???
