Thanks Peeder for letting us know about the issue with hum, since I wouldn't have known to buy that better power supply until after the fact.
Yes I think it's an outstanding product and a very solid value, don't get me wrong. Clearly better, via a 2192 at least, than the SSL Duende Bus Compressor. They nearly null, but where they don't null, the 7720 kicks its butt. I got the Smart emu on the Liquid Mix to null even closer, and that was a closer match but I still preferred the hardware. The HPF knob rocks.
Please repeat my noise test (just send digital black in from a converter and back out into the converter, then raise the gain digitally 70db with a Sonalksis FreeG or two...the comp doesn't even need to be engaged for the hum to appear) with both the included line lump and the CPS-1, and if there really is no difference, then by all means send back the CPS-1 for a refund with my apologies and report back. As my sound clip shows, the difference should be unmistakable. No Ebtech Hum Elimintor, Hum X, or de-racking the unit and holding it in my hands, tying the chassis to ground nor anything else would fix the hum, which is AC-based and not RF-based. Only the CPS-1 fixed it (90% of it anyway).
Plus I would also suspect the CPS-1 is providing more and better power to the unit...
