Yes, I believe that everyone who has listened to the Earthworks TC-20 matched pair has liked the sound. I like it because the sound is natural and neutral. That is to say, the mics don't add any coloration to it. It's as if you were sitting in the room while the recording was being made. But I admit I would surely love to have the Earthworks TC-30s! They're best known for recording piano. But it's $1,749 for a matched pair, so I doubt I'll upgrade anytime soon!
I find it easy to get caught up in this technical stuff. A concert pianist once reminded me that despite the piano, recorder, cables, microphones, room acoustics etc., nothing happens without the pianist! I think he had a very good point there.
As I mentioned in my reply to Monica, the Baldwin will be tuned next week, so if I have everything running, I might be able to make a recording sooner than later.
