l have to say this is really bad review, very unprofessional.
Surely if you had tested, or if there was issue, letting JK respond, prior to this its is poor review.
l normally enjoy your tests, but this seems so personal.
In the sprit of fair play, why not ask JK for a review sample, then test.
For what it's worth, l recently tested his ISODAC Supercap, l found the sound far superior to my RME Adi-2, l can't profess the technical reasons why, accept to say the ability to hear details clearer.
Lastly, can l ask why there is never an opinion on how the items being reviewed sound?
l only ask, out of interest.
l look forward to a proper review in the future, rather than a personal attack on a persons business model
