Thanks to all of you for your advise. One thing I neglected to say was that I had already switched to using a Mullard 5AR4 and Sylvania 6sn7 GTBs; sorry for that.
I had read elsewhere in Audiogon forums that the Mullard can be a bit 'overly-sweet' sounding, which I take to be overly-rich? So I was looking initially to change the rectifier tube for something which would give a crisper top-end. I read in another forum that the EML 5U4G has a more more open top end. Has anyone tried this?
Jwn, thanks for the benefit of your experience with the Oppo. I did think about this but then stopped when I read the following thread, where their observation was the the Oppo was fuller and warmer sounding. I am sure your experience was valid in your system; I guess that's the thing with our hobby; there are so many combinations and permutations and different outcomes in audio.
