Upgrade path from Rowland Model 10

I had the Model 12's and chased my tail with other amps. Looking back, I should have kept my 12's and a bunch in my wallet. Unless you have $ to burn, if you are happy with the 10's, keep them and enjoy them for a long time. You have a great amp.

Spend your $ on new music, improving the AC that feeds your amp, source, cables, speakers, tweaks etc. or any other weak link.

Feel free to email me for my experience with power cables for those amps.

Enjoy your 10's and don't fear that you are missing out on anything, unless you need more power.

I agree that the 10 is likely a little "warmer" sounding than the 201's.

For the fun of it, you may want to try and flip-flop your bi-amp arrangement. I think that the 201 might offer more openness & "air" with greater high frequency extension than the Model 10 gives you.

Have you tried running just the 201's without bi-amping? You may be happily surprised.

Considering the amps that you are using, in a bi-amp configuration, I think that you are wasting your time and flushing $ down the toilet, trying to improve on what you have going on.

A Model 302 would be the likely choice in moving up. However, the trade up will still cost you a bit-o-cash.
