Anything anybody does with tubes is simply slow and very colored.Nonsense! The output section of our amps is 600V/uV. Most solid state amps aren't that fast.
We've been working on our own class D project for the last 4 years which is now in Beta production. Its nice to be able to say that they don't sound significantly different from our tubes amps although they have considerably less distortion (most of it in the case of either amp is lower ordered harmonics). Put another way tube amps can be quite neutral.
