EMT JSD High Output - Charlie Byrd Direct Cut

My JSD has about 1mV ouput. Yesterday i heard the direct cut and the trumpets on the A-side were distorted at the loudest peaks. With my second cartridge, an AT-OC9 there was no problem. My phonopre makes 64dB gain and plays with the EMT clean, because i have connected a headphone amp to it. I think the input of my Pass Labs INT-150 is overloading. Same on RCA-Inputs.... Pass tells me the INT can go until 8V RMS on the symm. Inputs.

It is the first vinyl with this problem, but i am a little bit confused about this.

If you go to what you list as chain 1 and swap just the cartridge (Put the AT in place of the EMT), the system should play fine. Even if you don't plan on using your setup this way, it will be a good check to make sure that nothing in the system is damaged.

Going back go chain 1 as you list it. There is one simple thing you can try. I would give it a 50/50 chance of working. Remove the xlr IC's going into your Pass, install the jumpers between pins 1 and 3, and use a pair of single ended rca IC's instead. Going single ended will lower the gain of your source, and may be enough so that you can use your EMT. This is something that you really should try. I think it has a good chance of working.

Lower the gain on your phono pre. The EMT has twice the output of your AT.

You should list your system and explain how its all connected. It looks like you have quite a few options to work with. Someone may have a solution for you.

"OK, this record has the only piece of music that maked problems."

Once your audio system knows it can get under your skin, it will continue to do so.
