Stehno: I have had no problem with low end. In fact I pruchased W5 to replace Bryston 4BST (a bass master)based on reviews in both Sterophile and the absolute sound, both of which raved about it's phenomenal low end. In fact even in passive mode with the Adcom Pre, the low end is tremendous. I would like a little more midrange liquidity. Using Classe CDT-1 and DAC1 front end and B&W CDM7SE speakers. MIT top of the line cables all around except for illuminati balanced digital.
