Art Dudley reviewed the Kit One a few years back and his AA profile still lists it as being part of his system.Dick Olsher made the following comments on his web site in November 1995:
"Even after only a brief audition of Audio Note UK's Kit One, I'm ready to declare this single-ended 300B based stereo amp as the greatest SE amp value on this planet. The kit retails for $1,200, yet in my estimation it bests amps costing three times as much. Hell, let me be even more emphatic: this baby is competitive with amps costing ten times as much.
My sample came fully assembled from the US Distributor, (former distrib name excised - currently Audionotekits.com). However, looking over the construction manual, this project should be a piece of cake for an experienced home constructor.
The Kit One will not win any beauty contests. But this "Ugly Duckling" can sure sing. The music flows with gusto and verve. It squeezes instrumental images into incredibly palpable outlines. Soundstage transparency and microdynamics are outstanding. The upper mids, though, lack the sunny disposition of say a 211-based SE design. Harmonic textures are painted slightly gray in color."
These two gents both know what music and great gear sound like . . . .
