dev...yea..canada would be a stretch....all of your concerns regarding the amps ability to handle the qualities you mentioned are valid for any amp /amps one was considering buying.i can't speak about keith's room / setup ...although danial barnum , who used to own a very highend audio salon in illinois, thought it was superb. he is the dealer who sold keith the amps as well as his tidal speakers.i can speak about my room and the amp qualities mentioned above and i can say..as can everyone who has heard my setup / room, including doug white who owns 'the voice that is ' outside of philadelphia, that that the 'grails' easily shine with regards to all the above concerns..what you can't see in the pics of my room ..which is 25' x 18' x 25' high..is that the ceiling is an exposed redwood beamed, vaulted area where the beams are situated every 5' and extend into the room 2' at each attachment..this does create a pseudo-diffuser effect. i also have the back wall treated...bass traps in the corners and panels at the corners of each wall's
connection..all this done professionally.the entertainment center notwithstanding, the room is pretty good...could it be better..sure...but all of us, who do not have dedicated rooms , have issues..hopefully my amps will be back by this weekend as i am going into withdrawal...if you haven't read adam goldfine's, of Positive Feedback, complete review of the amps , on the Chalice website, it does go into most of the qualities the early 'grail' amps had. click on the 'full review' link at the bottom of his partial review. keep in mind that what he says was noted about what was, at that time, the prototype version. they have been significantly improved since..
