I want to echo Whitestix for his praise of Don Sachs restored HK C-1 it is one of the best preamplifier ever, especially for analogue playback. Guys like Sachs, Jim McShane, Jeff Day (Positive Feedback/6 moons) and the like, have state-of-the-art systems, great hearing, know what they are doing when it comes to modding, restoring vintage gear, as well as listening to much of the latest, greatest, modern top shelf stuff. When they make statements of high praise for something like the Harmon Kardon restored C-1, or restored and modded ARC SPC 6B or 6C, or McIntosh MX110z, I wouldn't be so knee jerk dismissive. So, Whitestix, you have a stellar preamp; the Sachs modded HK C-1, that is a Wow! I'm on the hunt for one. Best, Rob
