SimAudio i3.3 vs Naim SuperNait

I have an NAD 375BEE currently powering my Dynaudio Focus 220s and REL Stadium II. I'm looking to upgrade the integrated.

I love SimAudio with Jazz and Rock and the Naim with Classical and Acoustic Music.

Wondering if anyone has done a side by side comparison of the i3.3 and SuperNait?

Thanks!
