New Bel Canto REF600M using NCORE

Hey Audiozen... Good find! I'll have to check this Bel Canto REF600M baby out.

Meantime, here is the REF600M home page:

From Bell Canto REF600M specification/features page:

"The Bel Canto Impedance Optimized Input Stage is a balanced high Common Mode Rejection, low output impedance driver that is critical to the amplifier's performance, ensuring that the refined dynamic qualities of the recording are preserved."

This is what will give this amplifier its "bell canto flavor", and separate its performance from the rest of the Hypex based designs.

BTW I listened to a system using the NAD M22 two weeks ago, and wasn't impressed. The comparison was against an Accuphase integrated costing twice the M22, but not a lot more than M12 + M22 combined.

Is it just my experience, or Hypex (in general) requires very, very careful matching upstream? (downstream they are as speaker independent as I ever heard).

I would love to hear other users experiences.

One minor correction regarding the price, the new REF600M mono amps list for $2,495 each. They are currently shipping but I haven't had the opportunity to hear them yet.

Sebollo, M22 and Bel Canto Ref600 are completely different designs... Different manufacturer, different circuits, and likely different modules. I would not venture to guess sound of REF600 based on listening to M22.

In general, NCore tends to have a high input impedance, hence compatibility with upstream devices should not be an issue. REF600 in particular, seems to have an input impedance of 200KOhms.... So upstream compatibility should be a non issue.

Downstream, NCore appears to have a damping factor between 500 and 1000, so it is possible that it works best for speaker with normal or lower input impedance... For my Vienna Die Muzik, NCore is a wonderful match.
