RE: Todd hears things most of us can't ;-)

Posted by E-Stat on March 8, 2017 at 05:55:43:

Digital noise, RF, radio stations, signals from space, ultrasonic echos from flying bats. You name it, Todd can hear it. ;-)

Does seem that way! I take a break listening when the ISS passes overhead. :)

Indeed the EAR is a simple three tube MM preamp with an added SUT stage for MC duty. The SP10, by contrast employs a single eight tube stage for all the gain. Adding a SUT doesn't bypass anything.

The current REF Phono 2 takes a similar approach using four 6H30 tubes and JFETs (similar approach to my SP20 but with more tubes). I prefer using a single stage optimized for higher gain.
