Cartridge Question

I agree with Viridian and would add that if the same guy who told you that you needed a different cartridge because of the output level being too low on the Goldring, has done the setup;I would recheck it.
Get a decent protractor and a digital scale(this can be bought online for less than $30.00[not made for audiophile use])and check it yourself.
This is the level of the hobby that requires your participation and is some of the most interesting parts.
I would also use a vernier caliper (cheap at harbour freight)and make changes to the VTA until you like what you hear. Make very small changes and record your caliper readings.
This is assuming that you can make VTA adjustments with your arm.
Keep rechecking the overhang after each VTA adjustment.

By engaging yourself and learning to set up the cartridge,you will have a much better understanding and will become a better listener.

You will find yourself going to other audiophile homes and wondering if their VTA is too high or too low as you listen.

Personally I like line contact/shibata styli.They are always more detailed and revealing.What Transnova is saying about the Blue having more body and sounding richer is probably due to hearing the Black with incorrect VTA. They are definitely more sensitive.
Sounds like you have a nice system,enjoy it.

Brent it sounds like your scale should be alright. It needs to be accurate to at least two decimal points. Also, you will want to do your scale measurements beside the platter, not on it. Use a deck of cards to make the scale the same height as the platter,then take measurements.I would start on the high side of the recommended tracking force,and go from there.I would also get everything in the "ballpark" and let the cartridge break-in before fine tuning,otherwise you will have a moving target as it settles in.

I believe you can get a "Mint"brand protractor for about $100.00. They are custom made for your specific rig and are one of the best. If nothing else,download a protractor off the web,print it and then glue it to a piece of card stock.These can work just fine.Go slow and be careful.If you get scared, put the stylus guard on.
Pay attention to the VTA specs on your cartridge.The norm is about 20degrees,so there is a little rake to the stylus as it sits in the groove.Also, when you move the VTA the overhang will change,so re-check it.

In the long run you will gain a better understanding of how this stuff works and will also gain a better appreciation and enjoyment from the experience.

have fun,that's why we do this.
