Have the SS Paua and Hyperion MR cartridges. SS recommends on a loading above 470 ohms and states that below this level upper frequencies will be rolled off. My phono is adjustable between 25 ohms and 1750 ohms in 25 ohm increments. After my Paua was rebuilt a year ago it took a while for it to settle (about 15 hours at least) and initially was not happy with the minimal loading settings above 470 provides. Ultimately, after a little experimentation and a lot of listening, it now performs best at 725 ohms in my system. My Hyperion MR loads best at 525 ohms.
I'm new to Step Up Transformers
I've recently become aware of the existence of SUTs (step up transformers). My initial thought was " why do I need an SUT when my phono preamp (Zestos Andros PS-1) has a circuit for Low Output MC cartridges?
But many people seem to think that an SUT plugged into the MM channel of the phono stage will be a massive upgrade. I'd love to hear the opinions of anyone who has experience with SUTs. Thanks!
