MC Output Voltage - Impact on Noise

I thought that the default factory loading for the HP-100 was 500?

The Hovland website says, 530

If its 500-530 that is a reasonable default (not completely unloaded, but not too heavily loaded down either). The HP-200 that my friend had allowed for something like five different loading options, with the factory setting at 100k. Actually, we didn't even realize the unit allowed for different loading (who reads a manual?). It was only when the owner switched cartridges that we noted the noise problem and investigated by opening up the unit.

I am using a Denon DL-S1 on my VPI Scout. The output is 0.15mv and they recommend a load of 100 ohms. But at that load I find the sound a bit thin, so I tried it at 1K ohms and 47K ohms. It does sound louder with the 47K ohms setting, but the 1K ohms setting suites me better. I was told that it would be noisy at the higher load, but I was not able to detect any hissing or noise while I play some records. At one point I turned up the volume without a record playing and I heard a lot of noise at about 90% of the volume setting. It turned out that the TT ground and Phono amp ground wire was causing most of that noise. I am using a Modwright tube phono stage, my amps and pre amps are tube, except my McIntosh MC402 amp that I am using in a bi-amp configuration to drive the woofers in the Legacy Audio Focus 20/20. I was also using a Dynavector 20XH and that is much louder than the Denon. Now I listen with the volume set at about 20 to 25% and that enough form my room and I don't hear any noise or hissing. Now I am considering a Dynavector 20XL, used if I can find one.
