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

@d2girls, have you heard the Maestro Anniversary Integrated? That said, the amp I mentioned to the OP is a brand new (and much more powerful) model..

@jimbones Yes auditioning AA gear could be an issue, but you could talk to thier Canadian Distributor, Audio Alliance in Ontario who should be authorized to sell into the lower 48. They might offer a home trial + cost of shipping?

Another amp I can recommend is the Audio Flight FLS-4. That amp is well built, powerful, smooth sounding & musical. However you’ll run into the same issue with local Dealers, as the nearest Dealer is in Canada - http://www.audia.it/products/fls-8/stereo_power_amplifier-9/fls4-17.html.
Otherwise that deal on the minty KWA-150SE is hard to beat.
