I'm already convinced of their quality...the title was just to get attention : ). But I do have some questions. I'm looking at two heads on sale at ebay- one is the R600 and the other is the R1000. I have a 800 watt Dr. bass cab,and I was thinking about going for the R1000. Problem is, the R600 seller gave me a second chance to buy his item. So what do you guys think?? R600 or R1000 for the cab? Oh, they're both going for 280.00, by the way.
