atacgene,
I have no experience with a modded Oppo 205, but I'm suspicious of such mods. I do have an unmodded 205 and 105D. I think the SA-60 sounds superior to either as an SACD player. I recently replaced my SA-60 with an Ayre DX-5 DSD universal player that sounds a bit superior to the C-5xeMP, plays BDs, and does Roon via USB. I think $1500 is a fair price for the SA-60. If interested, I'm dbphd@cox.net.
