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 @mijostyn  it’s definitely in the 1k - 2k region. The Sutherland 20/20 doesn’t have this forwardness and after going through everything I can only think maybe the gain is off or a cart mismatch.

 

 

@pinwa they sound more alike then different but the Spinstsge is more lively. I like it a lot otherwise I’d just send it back. What it does right it does beautifully. What it does “wrong” keeps me up at night.

I bought the ipower SMPS but also tried a LPS. They did relax the sound but not how I wanted.

i bought it as I was curious about current injected phonos. I was pondering the Lino C but now not sure what to do.

the few dozen jazz LP’s I have sound great, as do the handful of classical. But rock music where lots of guitar and vocal fall into that 1khz to 2khz zone sound annoying. The Cult’s Love album. Ian’s vocal is right in that pocket as is lead guitar. It’s annoying.

@mijostyn @lewm  unfortunately I DK t have another cart to test.  The album I specifically mentioned I’ve owned in cassette, cd, Lp in several versions/masterings. It’s always been a good sounding album. It still is a good sounding album other than this issue. I have been trying to see what interaction is causing this.

i have a few things I’ll try tonight when I get home. 
 

after that, not sure what to do.

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.
