OK, I've received my AQ Vodka cable and I was impressed immediately right out of the box, without any burn in time. It was a dramatic difference to say the least. If anyone ever doubted that a $300 HDMI Cable sounded any different than a Sony $15 cable purchased at Walmart, they would understand immediately after hearing the two back to back in my setup within the first 5 seconds of listening.
About a week after listening to the Vodka cable, I came across a deal at Music Direct for the AQ Mocha Cable for $200. That particular cable has the identical construction of the AQ Coffee, including their dielectric system that shields the cable from EMI/RFI. The Coffee cable retails for over $500, while the Mocha cable in the same length was $200, and is identical in construction to the Coffee. Needless to say, I picked up one and have been listening to it for the last 30 days. Although i didn't have time to adequately break in the .6m Vodka cable (only listened to it for a little over a week before installing the 1m Mocha cable). I wasn't able to determine any difference between the .6m Vodka cable and the 1m Mocha cable, and they both sounded excellent. Given that the Mocha cable is really the previous generation Coffee cable, just rebranded, I returned the Vodka cable and am now listening via the 1m Mocha cable. I couldn't be happier with the improvement in SQ over the $15 Sony cable purchased at Walmart. It was a reminder that cables absolutely make a huge difference in SQ.
I wish I had been able to get shorter length Mocha cable rather than the 1m, and make a direct comparison to the .6m Vodka cable, but they were not available. Given that both the Vodka and Mocha/Coffee all have the same 10% Silver plating content, the only difference is that the Vodka doesn't have their dielectric shielding system. In my system, I didn't notice any sound difference between the .6m Vodka and 1m Mocha, but that's not to say there isn't a difference. I didn't have time to properly break in either of the cables so I can't offer any opinion other than I couldn't tell any SQ difference between the two in my system.
