I am very grateful for you taking the time. I am a big fan of your reviews and measurement reports which I think provide a very important balance in your magazine. I note re the resolution issue that the Society of Sound website displays the following quote: Malcolm Hawksford, Professor of Psychoacoustics at Essex University, reckons that, CDs digital specification was almost good enough for audiophile music reproduction. It was near the limit, but in my view probably a bit marginal. Ideally, at least 20-bit resolution at 60 kHz sampling frequency would have been better.
