SYSTEM a My friend has just sort of started a HT setup and so far has gotten a pair of JBL S310s, JBL SCenterII, JBL E30s on an Onkyo TX-SR502 Receiver. his sub is a 10" dayton. This winter he has about 400 bucks more to add to his system... My take is that he should jump into the Higher end sub market and grab the new SVS with the 10" driver for around 400. He is dead certain that his receiver is more in need of an upgrade because his new floorstander mains can handle way more power and this receiver doesnt have it. What do you guys think? Any other suggestions? SYSTEM B Also...coincidentally Ill have about the same amount this winter. My system is 4 Polk RTi38s, 1 CSi30, on a Pioneer VSX-812 that is hooked up to a Carver AV505. I too run a Dayton 10". What would jive best with my stuff?
