DYNAHI-- since buying this gorgeous piece of kit, it would appear that my hearing is aging faster than the rest of me! So it has literally a couple hours use, and has just sat on it's shelf for some two years. It is a beast--and heavy, it is FULLY Balanced internally, dual P.S./Transformers--and even switchable voltage! I am confident it will hold it's own against ANY flagship brand gear, but sadly I cannot experience the sonic splendor with my Chronic Tinnitus & 40% hearing loss! I ship ALL my goods double-boxed/bombproof & insured, so as to protect us both. I also have a pair K1000 AKG's with wood box + "pig-tails" for your power amp--which I will give first refusal to the successful buyer.
