I'm afraid you're not going to be happy with the answer...
Audyssey is DIGITAL room correction... so it's done in the digital portion of your AVR's audio circuitry.
In order to use Audyssey, but not the DACs in the AVR, the AVR would have to have:
DIGITAL AUDIO OUTPUTS *AFTER* THE ROOM CORRECTION AND OTHER PROCESSING.
To the best of my knowledge no "normal" modern AVR or preamp/processor offers this.
On a normal AVR or pre/pro, if it has digital outputs, they're going to be BEFORE the decoding and processing...
So the output on those digital outputs on the AVR WILL NOT go through Audyssey...
The digital outputs on many AVRs and pre/pros are also resampled... which may or may not further degrade audio quality.
The ONLY outputs you're going to get that go through Audyssey are ANALOG.
(Preamp outputs go through the internal DACs and some line level circuitry; speaker outputs ALSO go through the amplifiers.)
You CAN find external DSP-based room correction boxes, and external DSP processors, some of which may run Audyssey...
But I don't know of any AVR or pre/pro that does what you're thinking... you might be able to program a DataSat or a Trinnov to do it... and you could do it on a computer.
But this is just not an option offered on normal AVRs and pre/pros.
The only way you're going to access the Audyssey in a receiver is to use AT LEAST its DACs and analog outputs.
If you were to put the XDA-3 BEFORE the receiver then you would have to use both its DACs and its A/D converters - which would be worse.
You can run a sub by connecting it directly to the other pair of outputs on the XDA-3.
You can then use the crossover on the sub to adjust it.
Another option would be to use a PASSIVE LINE LEVEL CROSSOVER on the output of the XDA-3.
That would give you a full set of outputs for your main speakers and sub, with an actual configurable crossover, with both hi-pass and lo-pass filters.
A product like this one would do the job and actually offers some pretty flexible configuration options.
(It's unbalanced but, being passive, it shouldn't have much if any impact on audio quality, and it doesn't cost much to try.)
You could also use something like one of our Flex Subs... which include a full crossover in the sub.
Both of those options would obviously get you Bass Management but not Audyssey...
NOTE that the XDA-3 is a STEREO DAC... so you can add a crossover and a sub to it...
But it will be treating whatever content it plays as Stereo... with no discrete LFE channel... just Bass Management...
XDA-3 and two XPA-DR1's ordered, pending delivery.
I'm currently using an old Marantz SR7002 receiver. I like the Audyssey and Crossover features.
I'm wondering if I can configure a setup that allows the features, but still gets a clean signal to the XDA-3?
Or will any use of the old Marantz SR7002 before the XDA-3 cause the lower quality of the Marantz DAC to be in play?
Marantz SR7002 Receiver Review | Audioholics
The receiver does not have XLR's.
I'm using Amazon Firestick for source.
Perhaps a digital connection from Receiver out, to XDA-3 in would work? Would this perhaps give clean signal to the XDA-3 and without interference of the Marantz DAC?
I could still use Receiver LFE to the single subwoofer?
I'm not sure if Receiver > XDA-3 digital will bypass the EQ and crossover function?
Ideas? advice?
