Class D is just Dandy!

Offcourse it has always been about synergy and preferences,that should be a given.

VERY interesting. :) Please elaborate on the amps you are using, and how the speakers are configured (bi-amped? etc.)

Thank you!

Hi Kenny,

Just to be clear so that there is no misunderstanding that I am not here to advertise my product.  I am the manufacturer of the H2O AUDIO amps as some of you here know.  But since you are asking, for over 10 years I have used the icepower modules, and specifically the 500A and 250A modules to drive my Apogee Scintillas.  These are rated at 500W/4 and 250W/4 respectively. Recently, I have the implemented the NCore 400 modules just to see/hear what is the rave is all about.  And it appears that the NCore 400 drives the Scintilllas just fine with one caveat.  I have not really push it hard like I do with the icepower modules.  And the NCore is still relatively new and is still being breaking in.  As for SYNERGY.  I really think it is very relevant in any discussion especially with any audio discussion.  I will elaborate at a later time as this can take pages to get my point across.

Erik,

I use the icepower 500A and 250A modules.  The 250A module which is rated at only 125W/8 but can drive the Scintillas with no problem.  For those who are not familiar with Icepower, these modules do not come with the integrated SMPS.  I design the H2O amps with my own home brew power supply using these amp modules.  Biamp is always better with apogees which I have tried occasionally, but my system is currently configured as single amp with biwire.

That's fascinating, for two reasons:

1 - I did not know any ICEPower modules were rated for 1 Ohm
2 - The output impedance is quite high at the top octave

Have you measured the speakers with those amps?

Best,

Henry,
Keep us informed with the pairing.I wish you the best of luck.

I have'nt been involved with panels of any kind in a few years and now don't have the room for them anyway.But I did recently over the Christmas break try my pair of nc400's with a friends pair of Infinity kappa 9's with not very good results when pushed a little.The speakers sounded very strained and soundstage collapsed.I know these speakers well because I gave them too him about 15 yrs ago and I bought them new in the day.
The pair were restored by me 3yrs ago,doing the usual surround replacement on the woofers and I replaced all internal wiring and rebuilt the crossovers with better caps.We also tried my pair of ref600m with slightly better results.
It would have been nice to try a higher pwr ice on them nether of us own any.

Henry,
Can you give us any details about your special edition amps?

Kenny.
