37 Years and counting………

Our very first amplifier modification the MKH-200  for the Hafler DH-200/220 debuted in 1980 following the original 1979 products designed for the Hafler DH-101 preamp. The MKH-200 was met with high praise from those who owned it. From that meager start we have expanded the modifications to other brands, and finally we have added custom modifications for most any amplifier, including the likes of CJ, Krell, Levinson, McIntosh tube, Marantz tube, Sonic Frontiers, Muse, Nakamichi, VAC, Harmon-Kardon and too many more to name.
