Cables do make a difference! In this particuliar case, the substitution of a quality (Blue Jeans Cable http://www.bluejeanscable.com/) digital coaxial cable for the stock fiber optic cable to the digital connection between a Squeezebox3 and my Panasonic XR55 resulted in a very discernable improvement in overall sound quality. Granted this was not a direct comparison because it is also a switch in the type of terminal used (digital optical vs digital coaxial) but it is a relatively cheap, $20 or so, improvement that results in a substantial increase in SQ. The 340SE's are so sensitive that, sometimes, just a minor change in equipment can make a difference. I believe that the digital jitter was reduced from this upgrade. BTW, IMO, the Squeezebox is one of the most cost effective improvements that you can make to the enjoyment of your system. http://www.slimdevices.com/
