depends on what you're using them for... also depends on what amp specifically, lol.
i have an Eclipse amp that is a couple of years old. it was from their model line when Eclipse was known for quality.. now they've sold out, went cheap quality and are now being sold in stores like best buy.... i wouldn't buy anything new from Eclipse past 2003.... however, their amps before that were very strong.
if i were in the market for a new amp, i'd definately go McIntosh... you don't have it on your list though, lol, so ill vote Eclipse for their older stuff.
