Jeff Rowland to what?


I currently own a Jeff Rowland 625 S2 amplifier. I'm curious as to what amplifiers I should listen to below 20K, new or used. I'm not unhappy, but I'm curious. The amp will be driving Monitor Audio PL500 II's. The preamp is a Jeff Rowland Corus.

Hello G.,
A little birdie told Rowland will be releasing a new amplifier....735 mono-amps. 
Very interesting indeed. The 735 will be Class AB mono-amps. When my local dealer receives them, I'll be sure to go listen to them.
