One more comment; I agree wholeheartedly with Kinsekd above, and recommend a quality sub. I had good, but not great bass with stand alone 1.6's. I craved more low end. So, I added a Vandersteen sub. I understand that unofficially, the Vandy is the sub of choice for Magnepan. The Vandersteen takes it's signal from the amp and utilizes a crossover to feed only signals above 80hz to the mains (relieving 1.6's from trying to reproduce the lower frequencies). I believe this is explained on Vandersteen's website. You won't lack for bass with a pair of subs! I built HT this year, and added second Vandy sub; awesome low end!
Of course, amplification will partially dictate quality of bass.. But what everyone says is true, give Magnepans Power Power, Power and Whoa! Great sound!
