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!

If you prefer the D240 with the Electras, I would negotiate the best possible deal to buy the D240 outright from your dealer. Then, you can sell your 100.2 on Audiogon and probably put money in your pocket.

Dealers are notorious for giving very low value on trades. You have to remember that they pay wholesale for new stuff, so why would they give you market value for used gear - especially if you aren't buying something new and way more expensive.

I don't want to be a dealer apologist. However, it seems like this dealer spent a good amount of time with you and gave you the sound that you were seeking. That doesn't mean you have to accept a bad financial deal, but I would haggle with him and/or try the option I suggested.
herb4: Have you tried your 100.2 at the dealer's place with the JM Lab speakers? That might be an interesting experiment. I'd be amazed if the D240 sounded better than the 100.2. And keep in mind that there's a D240MKII, which most dealers (and Audio Research) believe is A LOT better than the D240.

Anyway, I still wouldn't trust that dealer. Market value of the old D240 is at least $1,000 less than the 100.2. Happy listening.
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!
