Class D is not going to give you tube coloration unless you explicitly add it. VTV has a tube buffer, but it isn't cheap.

Designed by Andrew Sparks of Sparkos labs, the buffer features a direct coupled dual triode driving a four transistor Wilson current mirror. The output of the current mirror feeds an I to V converter stage featuring a discrete opamp (of your choice). The board is compatible with almost any dual (or two single) opamps.

There are NO capacitors in the signal path.
The VTV Tube Buffer is compatible with all NCore and Purifi models and installs just like the standard VTV Custom Buffer.

Thanks for the suggestion. I don't need a tube buffer, though, since I use a very low distortion differential tube preamp (Vacuum State RTP3C).

  Really nice with one of the popular Class D amps. My Hypex Nilai's sound great with my Masterpiece 300b preamp.

    It would only work at its best into an amp with a balanced input, though. My current 300B amp is 100% differential. I feed my Hypex plate amps through the XLR connectors too.
