To each his own, but you might actually want to hear the 45's before making judgments like that. This kind of debate can go on forever. Personally, I fail to see how the stock Ascend Sierra-1 is worth twice as much as the SM45's OR my new Aperion Intimus 5B's. IMO, the improvement is nowhere near worth paying over twice as much (And I actually listened to all of those speakers in my environment). But that's just me. And there are a ton of people on this board who would disagree with me on that. To each his own.
By the way, SM450's go new for $299 to $350. You can get a pair of new SM45's on ebay for $360 out the door from a certain seller, or $400 everywhere else. Not even close to twice as expensive.
I agree...all subjective. btw, I got my SM450 new for 179.00 from New Egg, now about 1 year ago.
