Upgrade from my Modwright KWA 100SE


I am considering a KWA 150 SE, but not sure how significant a jump up it is from my current amp. Any experiences shared are appreciated or alternate upgrade paths. My speakers are my own Open baffle design (Satori MW16P and TW29) with a GR research H frame subs with AQ370 Amps. preamp is LS100. Thanks.

@jimbones nice! The Wells amps are indeed impressive. People that choose without giving them a shot are missing out. My Innamorata Signature is completely free of any solid state artifacts. Lovely amplifier.

I am VERY happy with my Wells. Although the amp has gotten good reviews it still flies under the radar. I prefer it to Pass as it has character. If you are looking for bold this is the amp. I find many higher end amps to be uninvolving. This amps sucks you right in to the music and wont let you go!
