D-SONIC SOA Class-D Core Amps. The best Class-D ?

Ahem. Audiozen, just want to set the record straight and that is H2O AUDIO has been and still is around...Alive and kicking :-). H2O have never went out of business. Not sure where you read that but I just want to set the record straight. And thank you for the praises. While I still have all of your attention :-) I'm willing to send a stereo H2O amp with all the latest and greatest tweak for a tour if anyone or a group of you is interested. Thanks

Audiozen,

The Website has been running fine for awhile now. It used to have a few problems but that had been corrected. I just google it and it came up fine. The 804 area code is when I was still in virginia. The current website has my current contact info. oh BTW, the H2O is still the best class D but of course LOL! Just kidding there :-).

Audiozen,

I just noticed that you still haven't recognized that H2O is me, Henry. So yeah! It is me Henry of H2O AUDIO :-)

Audiozen/Tom,

you guys must have tried iceh2o. Iceh2oaudio is the website address. It is there. Thanks again for your interest Audiozen and Tom.

I'm not sure what is going on but It works fine for me. What browser are you gents using? I use google chrome. However I just notice that some of the link is not working. Links to all the reviews next to pictures seem to work but not for the pictures to get the specifications. Guido when I click on your link you provided, it does take me to website's homepage fine. But like I said, some links just doesn't work. Looks like I need to talk to my web hosting provider. Thanks

Henry

derailing the original thread was certainly not my intention. Audiozen, I still used the B&O modules. Thanks again for who alert me on the H2O website problem.

Audiozen,

All is good now. Thank you all who alert me to the website problem.

Audiozen,

Thanks for the interest. Yes 8k input impedance is low but not too terrible low. One has to be a bit judicious in choosing the preamp. Of course, most if not all solid state preamps will drive the amp fine. The only exception is those with open loop design and/or some tube units. Changing input impedance is certainly an option but I'm not equipped to work with surface mount components. But more importantly, Raising the impedance would introduce more noise, plus I like to keep the original designer's intent of how it should sound. I have not tried either Abletec or the Hypex, though I have customer who have listened to the Hypex Ncore so I have a very good idea of how they sound. I have intention of getting a couple the Hypex Ncore to try but discourage as the lead time is exceeding long, plus the fact that that the modules are extremely expensive so I have put it off so far. Someday I might try it. So currently I'm still using the Ice modules without the integrated switching mode power supply. I use traditional linear power supply for my design.
