Lee, you're correct that the T765 doesn't have an input that connects directly to your computer's audio output. Since you're considering a new receiver, I'm a bit curious about what would be impressive enough about the 765 that you'd get it rather than a unit such as one of the Denons or Onkyos that has such an input. Although the 765 is typically excellent for amplification, it has been around for a few years and some of the features are somewhat dated.
Be that as it may, I assume that your main interest is the streaming classical stations, as is mine. What I've used for about nine years to connect the USB output of my laptop to one of my receivers is the Xitel Hifi Link(now called MP3 Streamer
). Another product with a similar purpose, but using a separately purchased optical cable to make the connection is this
. For the use in question a simple device such as these, which allows a direct wired connection, is fine.
