Initial impressions of Hagerman Trumpet MC with an AT740ML (mm) cartridge:
Wow!!! Ballsy. Bass Supreme. Simply better in every dimension from top to bottom than the Phono Box RS with an outboard power supply. First off, it’s much louder than the Phono Box RS...this with a quieter noise floor. My AT740ML never sounded better. Lot’s of nice detail/timbre.
Jim Hagerman was able to make a wall wart PS quiet. Brilliant. I suppose you can get an outboard powersupply...but he basically solved the problem with the circuit topology.
I’ve always hated fussing with the load settings at the back. That’s another pain point gone (the first being noise).
I will post more detailed impressions after it settles in and I can get the AT33PTGII cart in there to see how quiet the MC settings are. But for now...so very happy. Can’t believe this thing costs about a grand. Ordered it on the 12th...so fairly expeditious shipping.
I think this phono preamp is going to change the performance/cost landscape.
