Sorry for my English, but as a child I studied Russian language only .
I use a google translate to make this message.Now it’s time for little review.
Your opamp is very melodic , captivates romanticism ,nostalgic sound (vintage or tube sound ? ) ,
slightly warms on top
slightly warmer bass ,
slightly cools down the middle.
slightly warm, soft , fast, low descends ,
seems to be recessed , nicely fills the space
I think this is due to the fact that the opamp has up to 140 dB in open loop gain
but is OK
broad, with a slight reverb adds color and personality to it
