I listened to ST1000 and this 'little dude' really has something: control, speed, never goes hot very clean and natural sound. They could play any music and you can use them for movies as well.
Definitely large step-up to Bryston and Parasound on identical power, not any worse than Krell that could set your place on fire and somewhat close to the Pass and BAT amps.
The other 'price buster' is Sunfire Signature 600 load invariant amplifier.
