2nd Rowland Model 1 to improve my Aerial 10Ts?

My first day and post here, so pardon me if I stumble a bit!

I have a pair of Aerial 10Ts, Wadia 6 CD Player going balanced in to an old Rowland Model 1 (60 watts @ 8 ohms, 120 watts @ 4 ohms or 360 watts bridged), with interconnects and speaker cables being Synergistic Research that are essentially matched for the gear. I thoroughly enjoy what I hear, which is why there have been no purchases in 5+ years. However, I sometimes think about adding a second Rowland Model 1, but have no idea what benefits, if any, I would get. My room is adequate...not bad and not great. I listen at moderate volumes, generally listening to blues, jazz, and classical. What improvements might I get by beefing up the power with a second amp? My thanks in advance!
