Zu speakers with Atma-Sphere M60 amplifiers

Regarding impedance, which is what is important when discussing matching to Atma-Sphere amplifiers, the Definition and Druid are two completely different speakers.

Definition MK2 - 6 Ω nominal full bandwidth; 8 Ω nominal from 40 Hz - 35 kHz equal weighting

Druid - 12 Ω (nominal full bandwidth)

Considering these specs, and the fact that the S-30 has a higher output impedance than the M-60, it stands to reason Ralph would prefer the Druid with the S-30.

M60's (HOT) in Canada will work just fine with Zu speakers but here in FL. the S30 will have to do.

The AS/Zu combo will be a treat to hear everytime you fire them up.

Tvad,

Read the thread again; Ralph preferred the M60s with the Druids, not the S30. Not sure how that corresponds with the respective output impedances. I agree with you that the science says the S30 would be better with the Druid, but his statement seems to contradict that. Maybe the extra power and headroom overcome the effect of the impedance mismatch.

Tvad,

You're right. Can't explain it. Maybe Ralph can.

More than ever, I'm convinced in audio that 1+1 does not necessarily equal 2.

as an aside, I have heard the Pass X-30.5 isn't a perfect power match with Definitions as well. perhaps it's related.
