I know this is an older thread, but reading some of the submissions has stuck in my craw. I have one of the original 301's and I love its sound quality. The soundstage is huge and mates well with the Revel Salon2's. The sound is definitely more euphonic/liquid than analytic. There is no reason at this level of implementation to badmouth Class D, for one it is very ecological and efficient and Jeff has done a great job with the execution of this design. One caveat that deserves mention I have had to include a transformer in the line source to knock down the NZ 240 V to mate with this 230 V design. This has resulted in an audible reduction in the noise floor. I have owned JRDG amps since the mid 80's starting with the Model 7 and 9T and while I use Meridian Reference gear for the front end, I find the combination harmonically rich and musically involving. Are their better amps out there in 2020? Absolutely, but are they more musically satisfying? The answer would be based on a subjective assessment.
