Two digital components that have particularly impressed me. I've bought both, one on the basis of a review (a first for me) followed by a home trial, the other because it was available cheaply on the used market and I was curious about the benefits of its wordclock input.
First is the Aurender music storage and player. Used with downloaded hirez material, it provides the best digital content I've heard. Mine is the s10 unit which I connect using asynchronous USB; next step is to replace it with the w20 which has direct clock input.
Second is Squeezebox Transporter. Bought on a whim but I must say, sound when wordclock locked to my DCS Scarlatti, is outstanding. I use it for streaming Flac files from Qobus.
