Oh yeah Mike, your book is already in my Amazon cart. ;-)
Before I visited Walt’s Livermore shop, I went up to Berkeley to investigate a newly-opened storefront. I can’t remember what he called his place, but it was the 1-man operation of David Fletcher, later known for the Sumiko MDS-800 tonearm and SOTA turntable. The shop was a mess, like the desk of the mad genius he was!
I also visited Sound Systems In Palo Alto, where I heard the Infinity Servo-Statics. But the owner and his one employee were such a-holes I continued my search for a great high end dealer. I found him in Walter Davies, who was not only an experienced listener, but also a trained technician. A good thing, too, as when I turned on my brand new ARC SP-3 it made a loud "POP", and I smelled smoke. Yes, the pre-amp blew a resistor the first time electricity was applied to it. Welcome to ARC ;-) .
Roger Modjeski of Music Reference fixed a lot of broken ARC amps in his lifetime, so when building his amps used parts rated for ten times the voltage they would see in the circuits in which they were employed. Bill Johnson said he built his amps to last 20 years; Modjeski said 100 years. My Music Reference amps will outlive me. ;-) TAS reviewer Dick Osher thinks very highly of the MR RM-9 Mk.2, newly-returned-to-TAS writer Mike Fremer the same of the RM-200 Mk.2. If I'm not mistaken (@clio09, you there? ;-), Roger’s favorite of his amps was the RM-10.
