I'm in Greensboro NC. Ex opamp and cell phone chip etc. designer. Also designer of a fairly well known DIY phono stage and the SoTA phono stages.
Current main system is ML, Benchmark, RME, HSU and VPI/Miyajima.
Yes, J!m has done a remarkable job in all respects. It's been interesting to see how enthusiastic a number of builders are, despite the relative complexity of the task.
