Hello,
I guess this is a proper circle for this.

I use Behringer DEQ2496 as a source selector and room EQ. I connect turntable (analog XLR), CD (dig XLR) and DVD-A (dig optical) to it, then I take signal from digital OUT at DEQ and put it into digital IN at DCX2496 which is my active crossover. Later comes analogue volume control, amplifiers and speakers.

My main focus here is CD, or better 16/44 source in general, it applies to streamer or computer as well.

Fact is that DEQ does not resample, I checked. I red that DCX upsamples everything it receives at DIG IN.
If this is so, is there any reason to add SRC2496 before DEQ for improvement in sound of 16/44 source?

Now I have this - 16/44 > DEQ > DCX

If I add SRC it would be - 16/44 > SRC > DEQ > DCX, all connections digital.

In this case the difference will be that all EQ operations will be done in 24/96 instead of 16/44. Is that the only difference?
If it is should I expect it to be audible and beneficial? Is there anything else?

Thank you

Welcome!
I agree that this does seem to be the best circle for your question after looking around the site.

To be brief, I doubt you'd notice much difference between the standalone SRC and what Behringer has built into the DCX.
I could be wrong as I have not compared the two myself, but my educated guess is that you wouldn't see much improvement.

Just curious as your DCX crossover is before your volume, do you have multiple analog volume controls for your system? i.e. do you have to adjust everything to the same level for each channel?

I've got my PC spdif output going through a DEQ (actually two, as I needed more PEQ than one allowed) then to my DAC and then to the preamp. The volume is adjusted in the preamp, then the signals are sent to the active crossovers. This way I don't adjust volume for each channel. I put a lot of thought into my signal path prior to building it out, and am just interested in how your system is arranged after the DCX, maybe I could improve mine a bit!

Hello,
thanks for the answer. I was afraid that actually nobody have tried this...

As for volume control you asked, I have a semi-DIY four channel Goldpoint Quad Mini-V attenuator, controlled via one knob.

It is installed into their SA1 box without any connectors on the back. Holes are large enough to accept all eight cables which are soldered directly to attenuators, although these are quite thin Mogamis so they fit easily.

My idea was that if I use digital EQ and crossover, then I have to keep signal in digital domain as long as possible and at as high level as possible all the time. So I have only one D/A conversion total for digital sources, and also one necessary A/D/A for turntable. My sources are well level-matched. With EQ scheme that I use, for digital sources there is -1dB offset, for turntable -2. I never hit digital zero, but keep it very close.

Comparing to a modern preamp, downside is a lack of volume remote control.

How come you had not enough EQ power with DEQ and DCX when you actually have 4 EQs with this pair?

You can use GEQ and PEQ simultaneously at DEQ, then third EQ at DCX input, and fourth at DCX outputs, or that still was not enough?

My crossovers are XLR analog, and despite both GEQ & PEQ I still needed another 5-6 PEQ filters to tame the worst room modes.

Thanks for sharing about your setup!

I get it, I misunderstood that you have DCX.
