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.

I’ve heard the original KWA-150 & really liked that amp for the money. It had excellent build quality, sounded clean, resolving, tube-like and had excellent low level information, so it is a great choice if you like to listen at low or high listening levels. The SE model improves that further, and is apparently more open, dynamic & has better bass. The other benefit is, if you find you need more power later on, you can add a second amp & use the bridged mono mode. That amp apparently has good synergy with the ARC Ref 5SE and Ref 40th Anniversary preamps which I would prefer to Dan’s pre’s. Fyi, there is KWA-150SE fs on the ’Gon right now asking $3700. The seller has 100% positive f’back & is the original owner - https://www.audiogon.com/listings/lis93gc1-modwright-kwa-150se-silver-original-owner-pp-fees-include...

In terms of a an alternative upgrade path, I would check out Audio Analogue. They are releasing a new pre & power amp in July fyi. The Maestro Anniversary model is also a very nice 150 watt integrated fyi & is warm and rich sounding - http://www.audioanalogue.com/en/news
