Hello All,
I also thought the RNC put a gauze type sound over the tracks I used it on. My solution was to mod the unit by replacing all the electrolytic caps (which are xicon brand, not really great for high frequencies) with panasonic FM caps (105C,low ESR,high frequency). The veil was gone and I find the RNC to sound more transparent. It was worth while to do. It would be nice if FMR would just put Panasonic FM's in it stock, but I bet it would cost them a lot more money to do so on a large scale.
I spend about $10.00 on the panasonic FM caps, you can get them from digikey. Also the bi-polar eletrolytics (these would be the dark blue colored caps, the xicon's are light blue colored caps with a polarity strip on them) in the RNC are pretty good panasonics so no need to replace these.
Out Here,
Robert
p.s. I am not an audiophile weirdo, I just recapped my whole studio in November and I did the RNC as an experiment.
