In case someone is considering picking some up on sale: I just installed 0.1 uF 600V V-cap CUTFs caps in parallel with the 10 uF ClarityCap CMR coupling caps in my Beepre. Listening impressions with zero break-in are a first for me: everything seems improved - more definition, separation, musicality, attack and decay, from high to low. The added bass detail is most striking - not in the sense of being more emphasized than the added detail in the mids and highs, but b/c I had come to assume that bass notes are simply inherently less defined to the ear than treble and that there was little additional bass detail to be had. Not so!
cheers,
Derek
