I had Klaus’s top of the line Kismets mated with Rogue RP 7. Sold them and wish that I didn’t. Currently have a Coda CSiB but certainly doesn’t have the magic that my prior set up had.
I have had a Candela pre and a few other Khartago configs. It can be frustrating dealing with Klaus as communication can sometimes be challenging.
He is a one man show and not getting any younger so service down the road may be in question. Also his packaging is probably the worst in the industry. Considerable damage to 3 different pieces that I have had shipped/received.
