i'd recommend buying the audio innovations alto integrated amp (audio innovations is a subsidiary of audio note) currently being adwertized on a-gon for $275 (retail $500). i had one driving a pair of thiel 3.5's in my 26x28 kitchen, & this 35wpc amp aquitted itself quite well in a large room, driving these wery-power-hungry 4-ohm-load speakers. much better sound, imho, than comparably-priced nad, etc. admittedly, the kraken amp/pre i'm now using on the thiels, w/a class-a amp putting out ~100wpc, does a better yob than the audio innovations, but the retail price is $2160, & the thiels are wery hard speakers to drive. i'm amazed that the alto worked at all driving those speakers in that room!
in an office, w/91db/1w/1m speakers, yule have great sound w/the alto. and, the alto looks way-cool too - kinda like a spaceship - good for an office enwironment.
pick up a decent vintage luxman or sansui tuna for ~$100-$200 later on, & yule be set; or get a more recent adcom or nad tuna for about the same price...
good luck, doug s.
ps - for a foto of the alto go here - it's the top-unit, prolly in black, not chrome...
