Music Reference RM9 Hi end getting edgy.....

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Over the last week or so, it seems as though the high end in my system is breaking up a little.. Feels like it's always at the edge, and sometimes over. I checked it out and it happens with all sources, so I assume it's the RM9 (preamp is FT Audio LW-1 passive.) Tubes are: front, RAM matched pair; rear, Russian NOS from Upscale. The power tubes are 3 month old EH 6ca7 fat bottles....
Where do I start to look for the problem?
Thanks.
