The 777 seems to be a fine player but I think if I'm going to go multi-channel I may as well get a universal player with video. At this point I'm thinking about just buying the T100 (for my 2 channel music only system) at a good price and use the price difference to buy a universal player for my HT room. I can either just buy something moderately priced like the Pioneer 47ia or Dennon 2900, or pick up something like the McCormack in the fall. If I really decide that I'm missing out on SACD in the music room I could run a set of balanced interconnects from by HT room to my 2 channel room. It won't be as convenient as having the player in the same room but it will allow me to use my tube amp with SACD/DVD-A.
I did a little searching last night and I'm amazed at how many post on various site I've see where people have already bought into and give up on SACD or DVD-A. Most people site a lack of software and being under whelmed after the new toy glow wares off.
One of the attractions of this hobby is the process of making trade-offs and building a system that suits some personal needs. I found that the process of selecting other components (tube vs trans amp/preamp, speakers, etc)and making trade-offs to be fun. With these components no matter what the choice you are almost guarrenteed they will work well into the future.
The whole SACD/DVD-A/CD issue has been frustrating since the future value of the equipment is less in the hands of the audiophile and more in the hands of the vendors. If for example SACD dies on the vine you will have just bought into the next divix or minidisc. If it flurishes and you invested your money elsewhere you will have bought one of the last beta machines.. maybe on that bad since CD is not going away but you get the point...
Well this has turned into yet another long winded ramble...
