The problem is that turntables produce very little output, and not only do they need a lot of voltage amplification, RIAA de emphasis has to be provided or it sounds terrible. If you do not have a vintage pre amp a phone preamp will do this for you.
Here are the needle doctor's offerings. Prices range from $12,500 to $29!

Jerry Raskin the Needle Doctor has been in business in Dinky Town near the U of M in Minneapolis long before the net. He is 100% reliable, and the best source for anything to do with turntables. I have known and dealt with him for years.
You won't believe how much better it will sound with one of those preamps. The LP is a high fidelity medium make no mistake.
