Wow I am surprised how the "Clean Mode" took away the Boom out of your voice on the TD 510, the K669D sounds soooo smooth with that big pop filter on it, the K669C got real boomy in the "Radio" setting and was a bit sensitive to plosives, no different then most condenser type mics. Shame you were not able to do this with the Memphis Blue as well. The Bright setting was very bright on the 5 Core, the clean setting sounded the best on the 5 core. Keep up the reviews Clay, these are great. 👍
