I'm going to buy a sub later today; the Velodyne CHT-120 (I chose it over Polk and Definitive entries). I can try it for a couple of weeks, then I can exchange it for some other piece if I do so desire. It will be used with a set of MartinLogan Scenarios. Sadly, I won't see those speakers for at least a month; the importer said he'd have to order them from the States. The amp will be an HK6650R integrated, with 100W RMS at 8 ohms. It's the beefiest, sturdiest integrated I've ever seen, and currently powers a set of JBL LX66 tower speakers easily. Do you think the whole setup is sound? As I said, I won't be able to listen to it all together for a while, and when I do, I won't be able to exchange any piece (except the amp, of course). Thanks!
