What would you change?


I have a system consisting of an EAD Ultradisc as transport, a Benchmark DAC, an ARC LS-15 preamp, Gamut D200 amp and VR4jr speakers, and find I am hearing some "grunge", for a lack of a better word, in the leading edge of vocals. There seems to be an edge to the sound, not a sweetnes , and I am seeking some ideas of what I might change to rid the system of the sound.
I realize the description is a bit week, but all comments will be appreciated.

Thanks for the suggestions. I'll try a good cleaning of all connections, and the tube sockets. Time for the ProGold treatment!and the Nordost.
I've got a dedicated 20 circuit, actually two of them ,but power conditioning might help. I'm in an rural area and have no interferance from condo-type problems, or neighboring buildings, but other than that I may still have power probs and not know it.First a good cleaning. Thanks for all the helpful advice.

Stop re-using that Q-tip you got at the beginning of the year. Splurge for a box! They're cheap!

LOL.Ya mean I need to bust the budget again this year???...Damn!!..No Ferrari again this year!!
So, did you get rid of the grunge by replacing the Benchmark with GNSC Opus21?
