Doing set 1 pre 1 and set 2 pre 2 tells me nothing tho I want to hear each pre with the SAME MUSIC PASSAGE
The only way to really do this fairly is to have (2) of the same mics running within an inch or two of each other on the SAME stand running to the SAME recorder with each of the "contenders" in between. Regardless of how good a sound tech is, running at separate times tells us nothing (as Bean kindly points out). People standing in different spots or some slight EQ / instrument change in the mix is enough to throw off any other A/B comparison.
It has to be simply the same passage at the same time.
Unfortunately I only have 1 set of B3s, and I don't know of anyone local to borrow some from. I might be able to borrow a couple sets of CA-14s though...
I intended to open tape UM last night at the Ritz in Raleigh. I forgot what a terrible steel and cement barn it is, and opted to leave the comp in the bag. As much of an omni freak as I am, even I had to concede that spread omnis would've been ruinous. Plus, I ended up taking the taper GL spot, so I didn't want to be monkeying around with things and potentially screw up the primary recording.
SCR is playing tonight, but I'm not 100% on going. Either way, I'll get another set of samples ASAP.
