with a budget of approximately 800 $, what preamp would be a good purchase?
I have an ME-1NV and it gets a real workout in my humble studio.chris-from-ky said:I'll chime in with the same comment as Blue Bear... For $275 more you can pick up a Great River ME-1NV which I don't recall "ever" reading a bad review on. It's said to be wonderful and versatile. No, I've never heard one before but, I have read a load of threads here about preamps and Great River units are always held in high regard.
chris-from-ky said:People still like it I think. What turned me against it is that the maker of the RNP admits on the website that it has a higher noise floor than other pres and is a little noisy.
Yeah - in a lab -- on a test bench........ you'd never hear that in practical terms............chris-from-ky said:What turned me against it is that the maker of the RNP admits on the website that it has a higher noise floor than other pres and is a little noisy.

Start>>>WHAT SUCKS
Now I will violate a very important marketing rule by telling you what I think sucks about the RNP. Why? Because nothing is perfect and compromises always have to be made. By giving you some perspective on the RNP's shortcomings, at least you'll have some insights into the whys about my choices. Let your ears and application requirements be the ultimate guides (YMMV, right, Fletcher?!).
The RNP uses a wallwart. As I explain on our website for the RNC, the RNP also uses a wallwart to: (a) reduce internal noise induction, (b) to make the national/international regulatory compliance less costly, and, (c) to permit easy adaptation of the RNP to countries other than the U.S. The upside is that we've designed the RNP to use a range of wallwarts (see what's cool, above) instead of the pain-in-the-ass one used on the RNC.
The RNP is relatively noisy when evaluated by lab measurement. Many mic pres these days (including the really cheap ones) have very low noise floors (EINs of -127dB or better). The RNP's EIN of -120dB is obviously not as "good" as these others.
I decided that the sonic character (or lack thereof) and a decent price point were more important than the absolute noise floor. Why? First, many of the sought-after vintage mic pre noise levels are much worse than the RNPs. So in actual use, I concluded, many folks (particularly those "in-the-know") prefer good tone, even if it's slightly noisier. Second, even though we have internal versions of the RNP with a lower EIN, we'd have to charge at least $100 more for the privilege of meeting lab measurements that few actual applications would challenge. Third, the trend in microphone development has been to raise the output level of microphones, thereby reducing overall gain requirements of external mic pres. Are there some applications using the RNP that may be problematic? Yes. Will most of us encounter them? No.
The RNP has coarse gain steps of 6dB/step. Under ideal circumstances, when gain staging your signal path, you want to only use as much gain as necessary to do the job. Too much gain and you possibly run out of headroom. Too much or too little gain and you possibly get more noise than you'd like for a given application. So, why not use a gain pot or a switch with more positions to allow finer gain steps?
First, pots are notoriously inconsistent and imprecise for gain setting (see John Hardy's discussion of this) without using a two stage pot...one stage for low gains and the other for high gains. That's OK, but I personally don't like to have a "gain range" switch that can cause the gain to jump 30dB or more. This is primarily 'cause I've been known to inadvertently push the button at an inopportune time (don't tell anyone)! Second, 16 and more positions make for a very expensive switch. In an ideal world, I'd have a switch with an infinite number of steps to allow us to smoothly and precisely maximize the mic pre's dynamic range...allowing us to exactly dial-in the gain we need without too much noise or too low of a clip point.
Given these trade-offs, we've made the RNP with a twelve step switch. The lowest gain setting is 0 dB with a clip point of almost +28dBu. Each step then adds 6 dB of signal gain. Even though this requires that we (the users) are more careful in setting the maximum gain before clipping, its gain setting is a little less critical given the high pre-amp clip point. So, a user is likely to be more concerned with the signal being too hot further down the signal chain, at which point the signal can usually be attenuated to the appropriate level.
Of course, you can always get finer amplitude control by using an RNC in conjunction to your RNP. <<<END
All of you RNP lovers forgive me, please. I was only trying to help a dude pic a preamp.
