Just an update on optimising my system. My Rega went back for a minor repair-a known fault on the On switch-it was jammed in-now back and fine.
The combination of the Proac's and the Osiris is quite potent-it can get loud very quickly with the Oppo set at 100 on the volume output. The Osiris has a passive pre.
Using the variable option I found an output of around 75-80 on the Oppo gave me great sound in my set up with a bit of leverage on the amp control too-the fine notches on the Oppo can adjust the volume very nicely.
I asked on the AVS Forum about any negative effect in doing this-one poster suggested that below a 75 output the noise floor is increased but it is not particularly noticeable-from 75-100 he said it has no effect. Not sure how accurate that is.
But going direct from the Oppo into the direct option on the Osiris even with attenuators you can not even get close to 75-so possibly that has had an impact on the noticeably inferior sound I hear.
I don't know how accurate this might be-it would be interesting to hear what output setting those using the Oppo direct in a power amp are using.
