Not the only option. Pioneer BDPs output 2CH DSD as 2CH PCM 88.2kHz via optical. You cannot pass DSD via SPDIF: the spec itself does not support it. My Pioneer 140 only costs me a little over $100: the cheapest that I know of to pair with ext. 2CH DACs.
Get a modded Oppo ($1500)
Get 3 x wyred 4 sound DAC2 ($4500)
Get a good SSP for less critical sources (satellite TV) (Marants / Onkyo?) ($2000)
Good digital cabling (essential! $1000-$2000)
This might do better and you get MCH.
But the cost of better DACs could lead you down the spiral...
If you have more to spend, replace the wyred 4 sound DACs with Bel Canto DACs...
(same source as above)
A stereo DAC that sounds as good as what is built-in to the stereo outputs of the DX-5 is probably going to cost at least $5,000 to $10,000. And you need four of them. So your $400 modification is up to somewhere between $20,000 and $40,000.
