Is DEQX a game changer?

Thanks very much, Roscoe. Yes, I noticed that the HDP-5 has the "low noise" switching power supply, presumably similar if not identical to the one used in the PreMate, rather than the linear supply used in the -4. Just speculating, but perhaps the reason is simply related to internal real estate, with the touch screen and its associated circuitry taking up too much space to allow the presumably larger linear supply to fit.

As far as I've been able to tell from the website the only difference between the -4 and -5 besides the ones you cited is that the -5 includes the USB interface module as standard, within its $1K higher price, rather than as a $500 option.

Enjoy! Best regards,

To Al & Roscoe - when you get your DEQXs' I am happy to help with any aspect of explanation or setup if you need it...

Yes, many thanks Drewan. That is very very much apreciated. I will likely be in touch after the DEQX arrives. You rule!

DEQX is here! Did an initial set-up quickly using the DEQX wizards. But will probably tweak a bit today. Some of the measurements suggest I might need to get some room treatments behind my listening position, and might benefit from some different speaker placement.

Drewan77, I'll be in touch once I've got this tweaking worked out.
