Oh, and I have to admit that I did something very risky that could have cost me dearly.
I set the EAR 834 to mm and ran the output of the phono stage directly into the input of the Dynaco ST-70 with no volume control or mute switch. My Zu-modified Denon DL-103r has an output of .32 mV so I thought it might be worth the risk.
It was not enough gain, but it sure did sound nice.
I then lifted the cueing lever on my Tri-Planar arm and set the EAR 834p to mc to try the same experiment. Well, I instantly heard enough hum coming from speakers to realize that I should not even drop the stylus on the record. There was way too much gain.
Yes, I realize this is the "Done For Now" section of virtual systems, but all of my moves are pretty much tweaks now. The EAR 861 amp was the heart of the system for 5 years, so in Audiophile sickness terms, swapping out an amp after 5 years is "done for now". :)
In the future, I'm going to get a cartridge that only outputs .1 mV or .2 mV and then try my bold (crazy?) experiment one more time.
