Went to West LA Music on Saturday. I have to say, be careful, Customer Service is Excellent and they are very good salespeople. (David is killer) In a good way I mean.
I went in to look for something around $250-300. I walked away with this mic SE Z5600a II (not sure if it's "Mk"2 version) for $675. I really like this place!
So, on Sunday I recorded these with two singers. I had the SE5600a on the bottom and a Sterling Audio ST69 on top. Both on Figure 8 pattern. One singer in front, one in back. Going through Sebatron VMP4000 and Liquid Saffire 56. I also ran it through a ProVLA II because the singers were belting at some points of the song but I won't post the compressed versions so you can hear the mic better. (mind you the Sebatron is colored and smooth in my opinion) I'm also adding the music but keeping it low so you can hear the voices better. (and the music I got from youtube btw)
Also, these are raw, I haven't tweaked them so take that into consideration.
And to answer your question, YES, I do think that this mic has a smooth Top End. In fact, a Smooth everything. IMHO (in fact, the first singer I think benefits from this mic, and the second needs a brighter mic and I think the ST69 suits her better.)
