Dtanclim, Actually I am bi-amping with a pair of 201s for the bottom end. I use the Model 10 for the top end. The 201s are perfect in that application. I have never experimented with the 201s on top, but my ear tells me the 10 is sweeter, warmer and more tube -like than the 201s. Like my original post stated, I ask about a potential upgrade more out of curiosity than anything else because frankly its hard to imagine where an improvement may be had. If someone has replaced the 10 and has never looked back, I'd like to know what with.
Upgrade path from Rowland Model 10
Just out of curiosity, have any of my fellow Audiogoners upgraded from their Rowland Model 10s? I think this amp is spectacular, so I am left wondering in what ways it can be improved upon. Have any of you moved on, only to find that what you replaced the 10 with was not truly an upgrade?
