Thanks for chiming-in Jeff. If my calcs are correct there are only 4 sets out there. Yours, mine, Terry's and the set Eric keeps. Pretty small user group! On the hours, Eric says both the Ulfs and DI SEs have a pretty long break-in period due to the higher quality drivers. That said, I'm trying to envision them improving from where they are now. But I'm looking forward to it. I know my DIs improved a ton.
And I went through the upgrade cycle with the DIs before the Ulfs arrived. Since settling on the Lyngdorf there isn't a lot to upgrade. Maybe my Phono Pre? The 2170 is basically just one big DAC with a 170 watts PWM at the tail end. I didn't think anything would pull me away from the SS Analog side, but this piece did when first Ken, then Bill said I should audition it. As far as the front end... the Ulfs will bring out whatever sound you prefer. And everyone likes something different. Certainly, to each their own.
