Jolida JD-9 MC-High issue with severe distortion/clipping


Hello! I've emailed Jolida but won't hear back from them until Monday at the earliest, so I figured I'd run things by this forum first.

So, here's the issue:

My cartridge is a Benz Micro with a 2.5mV output loaded at 47K. However, when I hooked it up to the high output connections on the JD-9, the speakers would play nothing but severely distorted signals, not even music at all. This was at ANY volume. In fact, I would set my amp's volume to its minimum and when I turned it to the first volume notch, the severely distorted signal would emerge at high volume.

I can only play my turntable (VPI HW-19 Mk4) through the MM setting, with the IC's running through the MC Low connections. I know the specs for the Jolida settings in terms of what mV goes with each, but should the MC High really cause that issue? It didn't use to at all. I've tested cables and different inputs on the Primare i30 the Jolida feeds and the same thing happens regardless.

Many thanks for any advice.

Hi - yes, I set everything to the MM output/Low MC input. The distortion and clipping vanish, but is still there at the other settings when it wasn't before.
Thanks for that MM rec. Yes, I've done so. I'm just wondering why the other settings - the High MC or the Low MC - are distorting so much when they weren't before?
@yogiboy Yes, the MM is working fine. Thanks for the reinforcement. I'm just still curious why the High MC is producing such a blatant garbled signal. Could my Primare i30 be so different from my previous amp, a Hegel 160?
Thanks for the advice all. I've gone back to using the MM setting and the high output RCA's. @soundermn has a point with the tubes - the GE 5751's are higher gain than the stock 12ax7's that came with the unit.

But another factor is the Primare i30. I think that's going to have an effect on the sound, even if it's 60 watts less powerful than my previous Hegel H160.
