the best was the Audio Innovations amps (made under the second, tube management, between Qvortrup leaving to found ANUK and AI becoming merely another crappy silicon brand). One of the best amps AI ever made, in a notably distinguished lineup, was a PP 2A3. It might have been called "The First".

Well, you seem to be psychic because the Pure Audio 2a3 amp that
sounded so nice at this years show was designed by Guy Sergeant, who
had a hand in the exact Audio Innovations kit you describe. Shows how
much changes in 20 years or so in the business. Mind - Audio
Innovations were at that point pretty innovative in bringing out a 2a3
amp.
