Wondering what the current state of Class D amps is? A year ago I replaced my aging class AB amp with Orchard Audio GaN mono blocks, which
was a major improvement in bass foundation and low volume resolution. After living with these for a year still pretty pleased but have realized that in high treble
they could be improved on, as they can accentuate irritants causing me to keep a tube pre to smooth them out. Reading reviews in the past, this seemed to be the
one criticism of class D. I'm wondering if any newer technology has emerged for class D that resolves this?
