Is DEQX a game changer?


Just read a bit and it sure sounds interesting. Does it sound like the best way to upgrade speakers?

drewan,

Though the Premate unit was purchased as used, I was told that it was never used just the box was opened up. Perhaps it was used as a demo. Everything about it looks brand new.

Thanks for your comments on the BSG QOL. Tomorrow, I will try the high analog output from the DEQX into the QOL with the QOL then going to my amp. My logic is that I have the speakers and room set up with the DEQX, so I should be able to hear what the QOL adds. But, I also intend to try it the other way too, that is before the DEQX.

I changed the fuse to the SR Black, but I am confused. The unit says to use a 2A fuse but what was in it was a 1Amp.

I also changed the jumpers settings, while inside I noticed that the mother board says HDP-4 which is perhaps a good thing. But, on the power cables going to the IEC there is a cheapo snap on RCA ferret, perhaps a bad thing.

The logic behind my response is that DEQX corrects the speakers (+ Amps) & room whereas the QOL appears to deal with phase anomalies on the source recording. Adding this component between the Premate & amps will upset the measured relationship so I would not do that. 

drewan77,

Thanks, If the QOL is placed before the DEQX Premate would I need to run the measurements again?

"Thanks, If the QOL is placed before the DEQX Premate would I need to run the measurements again?"

No, the DEQX processor measures the effect of the speakers/cabling/amps downstream & the QOL is going to address source material upstream. This has nothing to do with in-room measurements.

The PreMate microphone measurement is based on a rising frequency plot created by the processor & will have no correlation with anything beforehand in the rest of your system (which is the correct way to do this).

Then, during normal listening, it will be fed a ’corrected’ source signal & it will phase & time correct everything for the speakers & room afterwards based on the chosen calibration.

.....If you added it after the PreMate (especially if you then took a measurement), the two separate phase corrections may give strange results & it’s definitely not as DEQX intended.


drewan77,

Thank you. I did place the QOL before the DEQX and I did do a complete calibration including speakers, subs and the room.

At the end of the room measurement I got these confidence levels.

L sub 27

R sub 26

Right 30

Left 33

Is this acceptable?

I must say I ’think" I have an understanding so far and I am up to chapter 12.

But, there are so many confusing graphs and flash forwards, flashbacks.

I have taken deep notes and each time I revisit the settings and notes I understand a little more.
