USB to glass digi out (Off Topic)

The only thing I can really deal with are the cigar and the Bushmill.
To find out what a Behringer U202 is it needs the Russian language I
think.

huh

Going through a DEQ2496 means molesting the sound (the DEQ lowers the
volume in the digital domain)

I actually have to drop the gain by 3db

> analogue inputs only, you will be going out of the DEQ analoguely. That

means two D/A conversions (and A/D) which can't be the best thing to do

The DCX2496 is connected to the DEQ with AES/EBU XLR

Again, what the U202 is doing I can't tell, but probably it only converts
USB to SPDIF.

That's my interpretation also

Having a Behringer for the DAC (that would be the DEQ) is IMO by itself
not a "decent" way to produce audiophile audio, so ... what to do ?

To my personal (!) experience, something like a DEQ isn't needed. I mean,
if you are bothered by standing waves or whatever anomalies in room
response, this should be attacked at the source (somehow). Too difficult
to explain, and for now please believe me.

I believe, I believe
I use it mostly to tame some of the worst recording I have. Just a little decrease between 3 to 8khz. I used its room correction to mixed results. Still playing with it.

When the DEQ is out of the way, you best have a crossover which works in
the digital domain from the beginning, hence no A/D conversion needed.
This way you will need a crossover with audiophile DACs.
Best would be a crossover operating in the analogue domain (does it exist
??), so you can use the best audio DAC you can pay for, that outputting to
the crossover.
Note that a crossover is different from a speaker (phase) correction
system, and if you actually need a crossover only, just build a proper
filter.

I'll have to learn how to do that. Not my expertise

When you have the DAC right behind the PC, and not molesting the sound
after the DAC by digital processing (starting with A/D conversion, and
ending with another D/A conversion, with the latter destroying your first
DACs efforts), it's time to look at how to connect the DAC to the PC;

IMO outputting from the PC with USB, while the DAC doesn't have a USB
input, is more or less useless, and the USB to SPDIF conversion might
destroy things again. However, you will be avoiding a soundcard then,
*and* you will be kind of avoiding XP molesting the sound.
Another way of doing this, can be outputting to an external soundcard with
Firewire being the best option for guaranteed transfer (opposed to USB),
the external soundard reclocking the data near to the DAC, and the
soundcard outputting in SPDIF (an RME Fireface400/800 will allow this).
This needs the "expertise" to avoid XP's sound molesting features (but can
be done).

This is gold thx for the advise (boy am I learning lots..take it slow I am a blond)

There are more ways, but the most important is that you shouldn't have a
bit molesting device in the chain (like a digital crossover), because then
you can do one thing only : have that one or two existing crossovers with
proper DACs (which IMO even don't even exist compared to the bunch of
normal audio DACs).

I am using the DCX for the sub only

So concluded : yes you certainly can achieve things by another route to
the DAC, but first throw away all the other stuff.

Agreed I have been a big fan of a minimalist approach in the past. I'm starting to learn that I've made some classic mistakes trying to achive good digital audio. My biggest mistake has been not putting enough effort into the source first.

Except the cigar and the Bushmill of course.

Well I got that one right

:wacko:

Thats me

Thanks so much i take all of this data to heart and welcome it

:wacko:
