Listening Impressions
My system has evolved from solid state to all tubes to the current setup of tube preamp, Class D amp on the mids/highs and Class D amp on the bass. As much as I love the sound of tubes, I think the Class D amps are the wave of the future in that you get the warmth and detail of tubes with a totally black backgound and much lower noise floor. Hence, more detail. With Class D on the bottom, the bass is much tighter, faster and gripped better than with tubes on the bottom. I'ved always battled brightness and edginess in my system thinking it was the true ribbons but my system couldn't sound sweeter or more musical than it does in its current configuration.
