A few years ago I built a two chassis dual mono K+K first generation phono stage with the seperate channel boards and used S+B step up tranformers.Previous to this I had been using a Pass x ono.I kept the Pass for over a year before deciding it was not getting enough playing time and I sold it to a seemingly happy guy in Denmark.At this time I was using a Bent S+B passive.Wanting to simplify, use less cable and up grade in late 2008 I had Kevin build me his absolute best attempt at that time regardless of cost phono with a line input and stepped attenuator volume control and cartridge loading control he decided on the cardas caps and LL1931 transformers.The result was an eye opener for me and I sold my prior pride and joy to a friend of a friend with less decision time required than dumping the pass.Knowing Kevin I am sure he and his crew will continue to tweak and improve the product even further.My very humble system of VAC70/70.s Quad 989,s and Dais table, Benesch act2 arm and Benz ebony lp may not have the ultimate resolution its not so bad. and The new K+K has been huge step foward in improving it.
