I owned the Opus 21 and now own a TRL modified Sony NS900. It is his best mod with battery powered digital to analog section. The TRL unit is so much better you would sell the Opus 21 after listening for 10 minutes.
TRL modified units are stunning and I say to you - go for it with Paul/Brian at TRL.
I have never heard digital sound as wonderful as my TRL Sony player.
