Understood. So how exactly are you doing the analogue level reduction - which Meridian item are you using? ... you seem to have a lot of it :-) RMAA uses normalisation to address exactly what you are doing by re-recording - to get an accurate apples-to-apples comparison. Even if you get to within 0.1dB it will still normalise during the test. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
