Yesterday I had the privilege of playing around with 4 BC215’s and 2 TH118L’s from Danley Sound Labs.

First we did a polar thing with 2 of them on a turntable to see what the response would be from them off-axis in 10º steps.

NO SOUND

No time to explain but here are the screen captures…..

SMAART I/O ended up displaying a 0.1dB offset to 94dB but was consistent over the full “gain range”. The Evo4 and the UA1010 stayed within level 1 specs AFAIK (i never read those spec but this is from “hear say”).
