Based on the direction of the $500, I'd say your dealer is jobbing you too. Fer a 100.2 and $500, I'll consider trading you *two* black D240 Mk IIs and even throw in a spare silver faceplate!
ARC 100.2 vs. D240?
My local high end dealer offered me a swap of my 100.2 plus $500 for a mint condition D240. I'm currently running a pair of B&W 640i's with an eye toward uprading to the JM Lab Electra 946. I also use an Aragon Soundstage pre-pro. I probably listen to 70% music (mostly acoustic jazz) and 30% movies. My listening room is an open floor plan that measures 20'x 30' with 10' ceilings. Which one would offer a more "tube like" sound? Is the the D240 a significant upgrade over the 100.2 or is my dealer full of it? Any advice or suggestions is greatly appreciated!
