I had a Doge 8 that was in my system for about a year and a half. I loved it and couldnt say enough good things. Read with interest about the improvements in the clarity and contacted Joe. The phono does not employ the jfet any more and according to Joe uses the same tube compliment of 4 12ax7. I asked if I could see a schematic but he said Doge would not make it available. I question how quiet the phono can be if its gain is increased to work with MC. Ive had a fair amount of experience with ax7 phonos and cant imagine how it could be quiet at the higher gain.From Emorrisiv's post it seems the mc improvemnt is minimal. I was considering trying one but the no schematic policy has me put off.
