I had the priviledge of hearing all of the audioquest interconnects and speaker cables on a pair of 927BE's starting at the diamondback and pikes peak. Each step up interconnect was better until we got to the cheetah and sky. These two were in a league of their own, I bought cheetah as I could not justify the cost of the sky. As for speaker cables the Monte Blanc produced the fullest, smoothest most unbelievable tonal balance I have heard from a pair of sub $20,000 speakers. The volcano, kilimanjaro and everest were better still but they were out of my budget. If you can afford the cheetah or sky interconnects with Mont Blanc I assure you, you will be pleased. We were using a Bryston SP1.7, 4BSST, Arcam entry level CD player.
