I just bought a Toshiba 30'' widescreen HDTV which has HDMI input.My current receiver is a Rotel RSX 1055.I am considering replacing it with a pioneer VSX-56Txi in order to have 1)Auto set-up/calibration , and 2) i-LINK.Ideally,I would like to have all components connected through digital input/outputs.My concern is that I am taking a step down in terms of sonic quality, or is the Pioneer comparable to my Rotel? Also, do any other manufacturers use i-LINK or am I limited to buying a Pioneer elite dvd player in order to make use of this connection on the receiver? And, is there such a thing as an i-LINK to HDMI cable that would allow me to connect a dvd player with i-LINK to my T.V. which has HDMI input?
