Michaelson & Austin TVA-10 power amp? Generally positive comments!

Just came across a Michaelson & Austin TVA-10 power amp. I Googled it and found a connection to Tim de Paravicini and his EAR 509. Has anyone here actually heard one of these live and would be kind enough to share "their" experience? [Runs for cover for the old grammar police]
