Like every Fidelity Research cartridge the tone of instruments is amazing and lifelike and this cart takes that way beyond what I have experienced before.
As for frequency range the cartridge goes down very low indeed and is very solid. Bass notes slam you in the chest. Nothing flabby or bloated at all. The upper frequency range is more prominent than other Fidelity Research cartridges I have owned, but it is very smooth and not at all harsh. It was a little harsh at first but now the cartridge has been broken in it is not harsh at all.
Soundstage and imaging is phenominal to the point it is holographic.
Best of all it is musical and engaging and allows you to get lost in the music without analyzing everything.
I absolutely love this cartridge and I’m so glad curiosity got the better of me and I bought it.
