BTW, You can buy mono block amps using these same NC1200 modules, same Hypex 1200 watt supply and Weiss op amps from VTV for $3000 the pair ($2600 with best Sparko Labs input op amp). Not as good of output wiring and output connections, nor chassis nor linear power supply for op amps. Still, a wonderful value. These modules are the same as what Mola Mola uses in their $17K mono blocks. The Mola Mola uses Bruno Putzeys discrete input stage while the VTV and Apollon use the Weiss discrete input stage.

If you want the stock op amp buffer built into the NC1200.....then a pair is $1800.....Dang! Even with the stock op amp it sounds really good. The Atsah amps sold 6 years ago for $9K using the stock input buffer.
