Ortofon Salsa LOMC resistive loading?

I don't have a specific suggestion but when you say "a good balance of acceptable bass" are you saying that you go from an either to much bass or to much highs? Or do you mean that you are unable to get the bass up enough to match the "very detailed high end"?

If your answer is the latter than I would check the VTA again. If the back is tipped up to much you will get a very detailed sound that is thin on the bass no matter how you load the cartridge.

I'm looking at the tone arm now and the front of the tonearm is ever so slightly higher than the rear and I'm not talking much.
The high end is really nice. Maybe it's just a different cart sound signature that might do it.

Need more info. Whats your table, phono preamp? Do you have other sources that don't have the thin bass issue?
