Excellent - Passes GradeA++. Lower noise is possible from 24-bit, but figures below -75 are not likely to make any difference.
A problem was experienced with the output being badly unbalanced, causing one side to overload the measuring input. After consulting Sonifex, two capacitors were removed, producing a centre-grounded non-floating output with very good balance (Lindos preference) |
