-scratchy sound when turning the volume pot;
- at different gain settings, using iem, 70 ohm headphone, HD600, and the DT880 600 ohm, music cuts off after 9:00, bring it back below 9:00, music comes back
- on the iem, from 0 volume to 9, muffled sound, beyond 9... Theres music but mono and no bass. Just highs.
After coming back, the sound is nicely louder. Detail is alot better even on the National. Initially, I thought CL was doung a fix on my unit. They changed the innards and maintained the same chassis.
Again, as I have always mentioned, CL and Dave conducted the transition and exchange with the utmost professionalism and stood behind the problems in a swift manner. He got my R on saturday, and shipped it back monday.
