I was hoping for more replies but that's ok. This can be a space where I just think out loud and if anyone wants to jump in and tell me how crazy this all sounds then that's fine.
The computer idea is getting a bit more traction. I would give up SACD compatibility unless I wanted to buy something like an Oppo BPD-93 (which sort of defeats the purpose of this exercise). Then again I only have about 50 SACDs and most of those are hybrids, so the investment in SACD that I have is not huge. I have much more content in the DVD-A format and 24bit FLAC downloads.
The computer can be used as my main PC rather than a dedicated audio device. The computer on my desk is about 30 months old, and will be due for replacement soon. Might as well kill two birds with one stone.
The cost for what I have in mind, however, is high and comes in at about $2,900. That much dough would buy a screamin' fast computer with a six core i7 processor, 24GB of memory, Nvidia GTX 570 video card, audiophile sound card, Blu-Ray burner, 200GB solid state system drive, and a 2TB 6G SATA hard disk for application data and music. I think I would get much more value out of the computer than I would a universal Blu-Ray player (which I have already said I would go as high as $3,500 for).
I could sell the Denon 5910CI and Transporter, perhaps recouping a sizable portion of the cost.
