Having owned that 801s3 I’d definitely go with the Rowland. That tweeter can get a little on the bright side with some gear. The Rowland model 8, which I also owned but with different speakers, is a fantastic amp. It’s not overly warm like the older model 5 was and has great control that you need to really get good bass out of the ported 801. This will also come down to system matching with your preamp cables and other components. What is the rest of the system like?
