Problem with block audio is the input imp. is low 10K unbalanced. Will not work well with a lot of tube preamps. Thats why I like Krells they are 100K. Gryphon is also low.

Yes, Gryphon is 10K unbalanced and 20K balanced. In my case, the CJ GAT 2 (tube pre) is 100 ohms or less...but i could see where 100K might create more flexibility (theoretically speaking anyway as I am no techie).

Things won't work without feedback. U can have no global feedback, but defiantly not " no feedback "

Thanks for the many replies and wisdom.
Excuse my ignorance... my question comes largely from that source I suspect.
Anyway, I’m looking for new amps to replace current BAT bridged VK55se used to drive my new Giya G2s. Was talking to MSB who touted their amps as not using feedback as though that was a great thing... hence my question. FYI, I just posted some pics in the member system section.
