Is DEQX a game changer?

Psag: "Drewan77, I didn't realize you were using the DEQX mate, which does not have the digital inputs."

I am not using the DEQX Mate, that was a reply I gave to Ozzy as he was looking for something with only speaker correction. My DEQX is the HDP3 which has both analogue & digital inputs, including a DAC which I no longer use

I tried the a/b without DEQX/with DEQX online demo at the deqx site with a pair of decent headphones. Glad to say most of what I hear at home off my OHMs with CLS (Coherent Line Source) Walsh style drivers sound much more like the with DEQX samples, as I would expect. Also I can relate to how things degrade from there in some other cases I am familiar with to various degrees, though the "without" samples in the demo sounded pretty extreme.

No doubt the "with" DEQX samples are much easier to sort through than the "without" samples.

Drewan77 if you are using the HDP3, then you are utilizing its DAC. The device operates in the digital domain. The last step is digital to analogue conversion.

Partly true...I will explain:

The internal DAC for processing incoming CD or streamed data is not used as the processing is handled by an external DAC & these sources enter the DEQX as analogue signals (via balanced input)

You are of course correct that once inside the HDP3, digital conversion takes place but this is to process the crossovers, speaker calibration, phase, timing etc which is entirely different to the internal DAC handling the initial music processing. That is a separate standalone component of DEQX which I am not using

Drewan77, so you are taking the 'raw' digital data and converting it to analog, then feeding it to the DEQX, which then converts it back to digital for processing, etc.

I do the same for CD/SACD. My CD/SACD player has digital out, but the analog out seems to sound better to my ear. However for computer audio I prefer running the digital computer signal directly to the DEQX, rather than introduce additional digital-to-analog and analog-to-digital conversions.
