Curious. I had been using an Ortofon 2M Blue and vocals were not quite sounding right, they sounded off a bit, not as deep as they should sound, if that makes sense.
I swapped in a Goldring E3, a less expensive MM cartridge, and that helped, not the last word, but pretty good.
I am sticking with MM cartridges as I have a Decware ZP3 MM phono preamp. My TT's are Technics 1210 & 1500. I like direct drive, as well as bayonet cartridge mounting, as I have the option of swapping out cartridges.
I did use a Hana EH cartridge. I managed to damage the needle (dropped it or what happens when you have the option of swapping). Vocals were vastly improved, especially male vocals, most noticeable on Elton John (live in Australia) & Neil Young (live at Carnegie Hall).
I have no experience with Hana's MC line or with the LSA amp, so I can not offer an observation from experience. Can't imagine you going wrong given that you will be doubling your investment in your cartridge. It is cheaper than doing the plunge into tubes, which was actually the game changer for me years ago.
Best regards,
Rich
