@lewm , isn't that something. I can't count the number of times I did something thinking it sounded better only to realize it did not. Expectation bias?
OP, you need to try another cartridge. If it works fine the Hana has shorted out. Please check the cartridge pins again. Are the Hana's color coded. Make absolutely sure beyond a shadow of doubt that you have it hooked up correctly. If the Hana's pins are not color coded it is very easy to make a mistake.
