In a system friendly to passives including a good autoformer type the music can be very good indeed. To some the sound is ideal, and based on personal preference, better then actives they have tried in the same system. Reasonable conclusions based on preference.
My experience is a great tube active has sounded better in my system with components that are indeed passive friendly. I have tried several good ones from Placette, Lightspeed and Bent. The active tube has won out in my systems and to my tastes. Simply more natural, meaty and fleshed out if you will. This is just my experience and I cannot claim you or anyone else will reach the same conclusion.
Fun to try for yourself and experiment.
