Couple comments I would like to add to this thread. 1st, the transporter is/was part of a music system that consist of a variety of network players, and open source software which streams music across a network to the above mentioned players. The system offers a lot of other services which creates an extremely powerful and flexible music front end. There are several types of network players, all of them have both analog and digital outputs
Sean Adams was the CEO of Slimdevices prior to the logitech purchase. Sean and his team of engineers designed and created the transporter as a statement product in 2005/2006. From all reviews I read he suceeded. The transporter ( transport & DAC) were considered a bargain for the price/performance and flexibility they offered. I use past tense, because I believe Logitech has discontinued the product.
Like most people, who have contributed to this thread I have not actually have had the opportunity to listen to the transporter, but I do have the squeeze center software installed on my Linux server and have 6 of the lower price squeezebox's distributed though out my house. My 2 channel and home theatre system both use all Bryston components. (4b's, bp25, SP1,) and PSB and PMC monitors. My 2 channel system DAC is Benchmark DAC 1 and I use the SP1 DAC for music in my multi channel system. Both systems have squeezebox's as transports. I have done some comparisons lately between the Benchmark DAC1 and squeezebox built in DAC. I can't hear the difference, and the DAC1 does employ a jitter buffer system. My 17 year old daughter could not tell the difference either.
I really enjoy the flexibility and sound quality I receive with my squeezebox's. I love the fact that I can synchronize the players if I am having a party, I love the fact that myself, my wife, son and daughter can each simultaneously and instantaneously access the 1.3 TB of music we have from any system in the house, or I can stream numerous music sources off the Internet.
There was a comment made earlier that "less is more" when it sones to bells and whistles with the transporter. I don't believe this true anymore than the Bryston players ability to play mp3 files reduces it performance with 24 bit material.
James has done a great job explaining in several threads what the BDP is and what it is not. I am pretty confident it is a fantastic performer, but at the moment I am not prepared to give up all the flexibility I currently enjoy with the squeezebox's. Plus I don't have any 24 bit material

.
Does the BDP sound better than the transporter? I don't know, like everyone else on this thread I have not yet had the opportunity to compare the two. I would certainly be interested in reading about a comparison, hopefully using a
common DAC (Bryston DAC perhaps?).
Does anyone have the capability to do this in the near future? The results would be most interesting.
