K & K phono pre compasison

The only phono pre that I have heard that betters the maxed out is Kevin's 3 stage differential design still in beta release only. For all you maxed out owners there is a mod you can do to the PS that will improve the performance at no cost. Just rewire the PS choke as shown on the Lundahl data sheet for better common mode rejection (diagram at bottom of sheet). This will involve cutting a trace on circuit board and adding a second twisted pair from the choke to the CB. I've done this to both my diff. K&K phono pre and a friend's SE K&K. Quieter backgrounds and better sense of flow.

Thanks for the info. This is just the kind of stuff I'm looking for. It appears that Kevin's maxxed out pre with mods is terrific. We're only talking about electronics, here, not voodoo. How do you get better? This is actually a question. You can only go so far, right?

Kevin told me in a phone conversation that the day he stops learning new tricks is the day he dies. I'm sure in a few years we can look back and say that the "old" maxed out wasn't even close to "maxed".
