VAC is untouchable in its mids and highs. I have a 300.1a and the detail retrieval, refinement, and smooth nature of the mids/highs is best I've heard. The lower registers are there, just not very pronounced. Very deliberate and tight as can be, but gives the overall sound a tipped up presence unless your speakers are darker/bass heavy. I am only running one 300.1a on 89db speakers with nominal impedance of 6ohms but big swings to 3.7 ohms. The clean, smooth, clear highs and mids, with tube magic on imaging/dimension, is addictive.
