Wes and JimmyT,
I don't think the C-1 and the C-3 sound at all alike, at least not on the "Studio Sessions" CD that I got from PMI Audio. They are both good tools, and I learned a lot from listening to the sample CD (for instance, that a mic that renders a rather awful vocal track when "dry" -- in my opinion -- can still sound great in the mix). To my ears, the C-1 and
the Neumann U87 have a similar character (not the same, just similar) that I simply don't like on dry voice.
When I listened to the promo disc, each of the three Studio Projects mics was a clear step up. The C-3 puts more space around the singer and renders (to my ears at least) a more natural sound. The T-3 improved on the C-3, but the gap between the C-1 and C-3 was larger than between the C-3 and the T-3 (which I hope helps to answer someone's question about how much better than very good can the mic be). I think someone here once said (if I may paraphrase) "use a regular condenser with a tube mic pre, and use a tube mic with a solid state pre." I disagree. I don't think a tube pre is going to make the C-3 sound as good as the T-3, for instance, or that the T-3 wouldn't sound good with a tubed preamp. Again, each had a distinctive sound, and the T-3 was a clear step up regardless of which pre was used, in my opinion.
I should add that the disc was also useful to me in auditioning the recorded differences among several preamps, most of which I was unfamiliar with. After posting my preferences, I then found out how much the ones I liked best cost! Yikes!
So it depends what you want to do. If you like the cuts through the mix sound of mics like the C-1, great. If you want something that will cut through the mix and still sound great on simpler, more acoustic recordings ("acoustic" is probably the wrong word, but you know what I mean), then $130 more for the C-3 is money well spent.
If you've got enough in the budget to bump up into the tube mic range (around $400 or so), then consider the Rode NTK or the GT
AM62, which was covered in another thread today. I don't think you could go wrong with either one.
And at $700 the competition really heats up, with recent sale prices in that range on the AT4060 giving the similarly priced
Studio Projects T-3 a run for its money. Unfortunately, my finances were such that I had to let go of
my AT 4060 before I got my T-3 so I wasn't able to do a side by side comparison (rats!), but I can tell you from experience that they are both incredibly great mics!
Also at the $700 price-point, you've got
the Shure KSM44, the AKG 414 BULS, and the Neumann TLM 103, all of which have been used to create some great recorded music, and all of which have fairly distinctive sonic signatures. (My wife and I are divided on the KSM32: I like it, but she thinks it's "too polite"; but we agree that the KSM44 is wonderful). I haven't had a chance to hear
the AKG Solid Tube, but it's also in that price range.
Above that, I start dreaming about a forgotten uncle leaving me an inheritance that will enable me to buy a U47 and U67, maybe a nice Manley Gold Ref, and some stereo recording sets from Bruel & Kjaer. Of course I'll need a stable of good pres and effects units to go with them. Uncle, if you're reading this, you don't have to die to bestow your wealth on me.
Finally, Wes, I think the difficult choice is NOT between the C-1 and the NTK, but among the C-3 and the NTK and the GT AM62. I have NO idea how to sort out that group of bargains. Which will hold its value best over time? Which will serve your various recording needs best? Which just sounds better, richer, fuller, more magical to your ears? Personally, I'd take a chance on the GT, just because it's a $1500 mic that became a $1200 mic that became a $875 mic that is now being carried by some dealers for as little as $400. But is it really *better* than the other two, regardless of price? Maybe you'll be able to tell me!
(BTW, I just noticed that ZZounds.com has the GT AM line at these sale prices, which means free shipping as well.)
Best wishes,
Mark H.
