I tried the Abyss on the Woo mono blocks at RMAF - not planning to buy one. Sorry, it's not my favorite. It was ugly, too heavy and stiff, uncomfortable, and bland sounding. My SR-009 via my upgraded KGBH amp with custom CCS have fantastic bass impact and dynamics, with great tonal balance, detail, soundstage, and imaging. They excite me in a way that the Abyss could not.
