I recently purchased a Furutech "Odeon" power cable for my new Sony TV and will be purchasing Audioquest's Vodka 48 HDMI. The Sony is excellent as it is but i hope to see even more improvement - "blacker blacks" as the Furutech ad extols.
TV and upgraded cables
Have you tried good audio cables on TV or projector? Do you see any improvement compared to stock cable? If yes, what improvement and what cable?
