Hi Anthony

I would just like to point out that I think your build quality is far superior to the Classe Audio, I've been doing some A/B testing of the 2 x Classe CA-M400
( http://www.e-hifi.com.au/classe/Amplifiers/cam400.aspx ) and the nxV500's.
I think the nxV500 are better, the M400's are $10.9k each!
You have made some fine amplifiers :)
