I personally love the NT5's for overheads- they are "big" sounding without being overbearing. One mans gold is another's tin, personally I wouldn't (and didn't) take the gift of an NT-5 or it's stereo cousin the NT-4. I beta tested them, and they sounded so aweful I sent them back for another set, thinking they had to be defective, but alas the replacement ones sounded exactly the same through a variety of mic pres and converters, thin and brittle, with nothing usable below 100hz, and painfully bright between 2.5-8k, so much so they hurt to listen to even at low volumes. Check to see if the Oktavias are russian or chinese made. If they are the russian ones, buy every last one, that's a steal, and they are incredible mics. If they are the chinese ones, while still a good price, don't expect them to be that fantastic. In either case, listen to every one before buying. Oktavias weak point is quality control. Some will sound remarkably better than others. If you're looking to get a pair, use this simple trick to check for a decently matched set. Plug two into a console, put the mics side by side, even on a table or whatever is fine, but so they are physically touching, and the front of the mics are perfectly lined up. Now, with gains set identical, solo both mics, and flip the phase on one. Ideally, you should now hear nothing. The less you hear, the better they are matched.
