All done. All signal wiring in silver/teflon, and Speedball boards back in. Bypassed the Dayton film caps with .01 uf FT-3's Even with the 'stock' tubes, this thing sings thru' the HD600's No Sennheiser veil to my ears. Great detail, more air around voices and instruments, fingers on strings, long woody decay on bowed bass notes, great tone, the whole enchilada. The soundstage is surprisingly wide, and imaging spot on. I know this sounds unlikely, but I recently auditioned the Audeze LCD-X's on the Wu SA6-SE amp, and the Crack w/HD600's is a contender. Righteous, Paul.
