I have a Rowland Model 2. I purchased the Battery Power Supply (BPS) after I had the amp for a while. I would have to say the amp is so quiet (noise floor) to begin with, for me the BPS is overkill.
That's not to say it may not help to have the BPS if you're driving horns or big Tannoys, etc.
The BPS does reduce the current available, to me, in my bedroom system, it's never an issue.........
