There is more then you think.
1) Bel Canto Design follow up their very expensive NC1200-based Black system with the REF600 monos [$4'500/pr] which combine an nCore NC500 module with an NC1200/700 switch-mode power supply, 27/33dB gain switch, XLR/RCA inputs and 300/600W into 8/4 ohms. There is a high input impedance of 200K, peak output current of 27A and John Stronczer's custom fully balanced input/driver stage that provides very low output impedance to the class D Hypex power module.http://www.belcantodesign.com/eOne/products/amplifiers/ref600m-amplifier/
The Taranis Stereo Power Amplifier brings a new performance price point for Audiophiles. Based on the Hypex Ncore NC500, it allows audiophiles to enjoy some of the benefits of the NCORE and Veritas technology, at a lower price.
The Taranis is designed with ultra-low distortion from input to output, and employs a specially designed high end input stage with a high current drive; together, these provide the output stage with ease, speed, detail, and power like no other.
Using the Hypex Ncore NC500, which is an Ncore output stage, and a custom input stage the Taranis Stereo Amplifier is a high end amplifier packaged in an affordable, eye catching chassis with power meters.http://www.merrillaudio.net/taranis.html
There is more just look for it.
