Waamamps ampifiers?

Is anyone familiar with Waamamps? I'm looking at their 2A3 / 45 SET and need some references about build quality, sound quality, etc.
I bought one of his amps a while ago (2009), single ended 807s. Good amp, but after I replaced the output transformers it sounded much much better. I used James HS6112 transformers @ $150 for the pair. Maybe you can get Wayne to use OPTs that you choose?
