Amount of feedback does affect gain but at the same time also output impedance, harmonic distribution, bandwidth...

Hmm I see. I tested for bandwidth between unmodified and modified channel, no changes whatsoever there but I don't have anything to test harmonics.

In your case the bandwidth change shouldn't have significant effect.

But who knows maybe you get the sound you will like more than you had with unmodified preamp:-)

I loved the sound before and don't really want to change it. I just read some articles about it being also a probable cause for instability, maybe this wasn't such a great solution (although it seems stable to me).

You can still try to attenuate the signal at AW60 input. Listen to both solutions and decide which one you like best.
Regarding the oscillations: the problem is that in most cases you will not detect them by ear because they occur at high frequencies. Far beyond from what our ears can detect.

I checked for oscillations by scope on a square wave as well as on a very high frequency on a regular sine wave, they both look perfectly clear of any oscillation.
