this is the guts of my amp. it has all 99.999% pure silver in teflon in the signal path, vishay s102 resistors, auricaps, panasonic electrolitics and much more. the results have been increased dynamics, more neutrality, a wider and deeper soundstage, better imaging, better bass slam, smoother highs, more fleshed-out midrange, quieter background and a much more musical presentation.
