Pre-Amp for Class D Amp

Any decent tube preamp or buffer stave would go nicely with Class D amps. As mentioned, tubes are the key to a well balanced system using Class D amplification. We have been designing around Class D for several years.
The Bel Canto's have a high input Impedance, 100K/200K ohms so there are no concerns there. They do have a rather high sensitivity at 3V but again, most preamps will drive them to full power with no problem

Your are correct Charles1. It was not written correctly. Thanks for clearing that up.

Sorry Charles1.
You are correct. My wording was incorrect. The lower the number, the higher the sensitivity.
Sorry for the incorrect wording.
