Upgrade from my Modwright KWA 100SE

@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.

@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..

Ok so I got a recommendation for a bel canto 600m. That's class D. Is it any better than my KWA 100?

Same amp basically so not much point

 
Not true at all. Different designs. The 100SE is a MOSFET amp. You will get better detail and resolution out of the 150, which will bring bigger more spacious soundstage. Also more refinement and much deeper low end.
