This is a very old thread, but since there are a few new posts, here's my recommendation buy a
Oppo 105 (which has built in VVC)
You can buy used 105s ~ $900. then upgrade
Im not a DIYer by nature, but the Asian company I purchased the following from has easy to follow photos on installing the upgrades
Go to eBay and select whichever Linear Power Module you can afford, also get the 110/220 jumper and replace your IEC with one that has a superior IEC (mine has Furutech with a silver jumper that connects to the LPM.
It's so good that I no longer use a preamp
