Raul, perhaps take your trolling elsewhere. In case you read it, this thread is about tube phono sections, not some solid state unknown as you seem to always push; the one that you have that no-one else can get; that is a cheap junk store technique. Show some class.
You have no engineering expertise by your own admission; for you to declare what knowledge that someone else has whom you've not even met is gross hubris and simply absurd on several levels. You keep talking about your 3160 thingy but its obvious you didn't have anything to do with its design.
Put another way, if you can't get out there and show the rest of us how its done, then sit down and shut up.
