Hi everyone,
I am testing my new preamp and I have some questions, maybe you can help me.
In order to test the preamp behavior, I send a sine signal of 1 khz at -18 dB to the preamp. If I want to preserve in the DAW the same level od -18dB I must set the preamp like this:

obtaining this signal:

So, at this point, trying to test it without clipping, I put the preamp in Line mode in order to obtain the cleanest signal, con this configuration:

and this signal (very clean).

But, If I want to obtain more colour, boosting the output transformer, I get this:

It's almost the same signal, without any harmonics.
Is this normal? Maybe I'm doing something wrong?
Thank you so much for your advices!
