Not enough info. When you use HDMI audio the sound is actually being produced by your AVR. That's where the digital audio is being converted to Analog. So the question is, does your AVR produce sound as good or better than the Analog outputs of the 95?
On interconnects, you can spend a ton of money on exotic cabling. I'm a skeptic (to say the least) when it comes to the claims of equally exotic performance from such cables. I think you should get a decent quality set of shielded interconnect cables from a reputable company like Monoprice or Blue Jeans Cable (both AVS Forum sponsors). Then AUDITION any more expensive cable you might find interesting.
If you can't hear an improvement, send the more expensive stuff back.
Note that listener bias is a big factor in such stuff. Simply put, buyers WANT more expensive cables to sound better. So get a friend to swap the cables for you without letting you know which ones you are listening to.
