Transimpedance has too much gain?

I’m running an AT33PTG/II through an Andover Spinstage. Overall it sounds amazing but there definitely an emphasis on the 1khz region that makes some records hard to listen to. Its louder than the 20/20 and I have been swapping out parts to find the cause.

could the phonostage be adding too much gain?


Thanks @lewm  I will run a couple tests tonight. 

I know little to nothing on things electrical but what you said makes sense.


should know more later.

@gochurchgo I wasn't familiar with that Love album but listening to it on streaming it is easy to see how that guitar could quickly become irritating.  I don't listen to that kind of music but I have had other preamps that produces what I call glare in that same frequency band.  It would only happen on 10-15% of the tracks I played but I couldn't stand it and I ended up selling that gear.  Sadly, all I can tell you is I'm not hearing that with my Spinstage.  Assuming you like everything else about it I would return the unit and get another one.  @lewm's suggestion that there might be a faulty part effecting the RIAA curve is plausible to me.

Also, I think the Lino C only takes balanced inputs.  No idea if your turntable supports that but it has stopped me from trying one.

pinwa, Any tonearm can be easily adapted to provide balanced output from the cartridge, because nearly all cartridges in common use are naturally a balanced source.  We use them in single-ended mode most often, but that is just because we ground one side of the output in order to use the RCA inputs on a typical single-ended phono stage. And of course, the turntable is an innocent bystander, when it comes to the signal output.  It's all about how the tonearm wires are terminated.
