Well I got 6hrs on this cart so far. It has very similar dimensions to the Dl-301 so instalation was a snap. Oh, I stuck a little dab of blue tack on the nuts and stuck in place on the cart so screwing the screws from the top was a breeze! Oh man, the magnet on this thing could pick up nails from a roofing job! Anyways the first thing I noticed was the soundstage; how huge it is! And the soundstage on the DL-301 is no slouch. The ART9 has better highs, detail and bass than the DL-301. But then again its in a different snack bracket! And everybody kept asking me how much better can it get? It was hard to imagine cause the Denon is a great cart for the price. I just wanted a cart to end my quest for a great table/cart combo; to retire with. I read that it takes up to 100hrs to fully break-in. Oh, the first thing that I noticed when I played a old Nancy Sinatra record was the BLAT from the horns! Just great!
Cheers, Doug
