I bought my Khartago new from Klaus years ago and it has been back for a couple of upgrades. After a lifetime in this hobby I have to say that, although I turn my gear over frequently for the fun of it, I have never seriously consdidered selling my Khartago. My current love affair is with a marvelous low powered tube SET but from time to time the Khartago goes back into the rig for a few weeks. It's like putting on a comfortable pair of old shoes. The music just flows but the detail, clarity and "rightness" are all there. And on a value vs. price scale Klaus is practically giving them away. You're gonna love it.
