[Note, I also posted this on the ProAudio forum; if against the rules please delete this one.] (Note: I'll only consider new mics.) C 414B-XLS is flatter - which I want. C 414B-SLII has a rise for vocals. Either can be bought in a matched stereo pair. I thought I had decided on the XLS matched pair, for $1,999 per four online sources. The problem is I just stumbled across that new 414 LTD at Guitar Center for a great price. AKG recently released a “limited edition” C 414 LTD which I believe is technically identical to the XLS, just some cosmetic difference and a couple hundred bucks more expensive because they are playing off the collector’s item thing. Unfortunately they are not available in matched pairs. Here's a link describing the 414 LTDs; http://www.akg.com/site/press_center/powerslave,id,107,nodeid,0,_language,EN,nodeid,33.html Today I was in Guitar Center and noticed they had 414 LTDs on sale for $900, which is $300 below their usual discounted price of 1200. (retail is supposedly $1500.) So now I’m trying to decide how important it is to get a matched pair. AKG site SNIP: The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 300 Hz to 8,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program. (end snip) Then I looked on Neumann’s site and their mics are not even available in matched pairs. So maybe getting matched pairs really doesn't matter that much. (Then again, perhaps it’s because Neumanns are made to tighter specs than the 414s.) I’m using them to record classical piano, a new 9’2” Bluethner grand, in my home, also acoustic guitar and voice. Today I just have a lowly Mbox, but will eventually upgrade to real preamps. So should I grab two of these (non-matched) 414 LTDs for $900 each tomorrow, or pay $200 more to get a matched set of 414 XLS? Thanks.
