Pre amp/interface upgrade for location recording

Postby Reuben Anstey » Sat Aug 11, 2018 3:32 pm

Scouring various forums, there are such differing views on the hierarchy of mic and preamp/interface. It makes my head hurt.

I'm going to conclude that these opinions are based on many years of trial and error, and the conclusions reached are personal to each engineer, thus equally valid. So with my relatively limited experience, I think I should just try to obtain the best of both within a price point and treat them equally.

I am currently using DPA4006 mics into a Focusrite 6i6Scarlett interface into laptop DAW.

Assuming impeccable mic placement and all else being perfect in the signal chain (!) what would I have to pay to obtain a significant upgrade in audio quality from my current interface?

Many thanks for your time!

Mostly upon what you regard as "significant".

You can spend a small fortune in an almost infinite number of ways to obtain an almost infinite number of differences. Which, if any of these differences are significant will vary from person to person.

You have decent mics, and decent interface. Inches of variation in mic placement will produce much bigger sonic differences than changing either of those.

Are you looking to change something for a reason or is it just a matter of curiosity?

You're right in your conclusion, btw, and I'd suggest that you've got the kit balance about right. Your mics are amongst the best available (personal preferences may vary but they're great mics), and your interface offers a very good balance of features, sound quality and price. Ok, there are definitely technically better interfaces which, in an A/B comparison with the 6i6 could produce technically/audibly 'better' results but, taken in isolation, if you can't produce an excellent recording with the 6i6 then it's very unlikely to be the interface's fault. You could pay a little or a lot to get a difference but your present interface isn't likely to be a a significant limiting factor in the quality you can achieve. If I were in your position I'd worry more about getting as much experience as possible with my existing setup before I'd bother with changing anything. With more experience you'll be better placed to judge whether any 'problem' you hear is consistent and due to a particular piece of kit or just a changing personal preference.

There's a lot of bobbins talked online, particularly about preamps, and they're often ascribed magical properties to which they simply can't live up. My feeling is that unless you have the funds to indulge a bit of gas, so long as the preamps you have to use aren't actually significantly degrading the signal, or imposing a strong sonic character that's against your prefernces there are so many more important things affecting sound quality than what preamp you choose. Same goes for converters, etc.. It's nice to be able to spend the money needed to optimise (to your tastes) each stage of a signal chain but the law of diminishing returns applies with a vengeance and it's very easy to spend far too much obsessing over really insignificant changes. Also, how different bits of kit perform usually depends heavily upon how they're used and the context of the rig surrounding them. (Check out the preamp comparison article on this site (which was done by people who know how to produce a valid comparison) and the followup article and threads on the forum. )

However do try other things when the opportunity presents itself (preferably without it costing you anything) - you might find another interface/preamp/AD/whatever that really stands out for you as an obvious improvement but be aware that differences are very beguiling and it's easy to spend a load of time and money jumping from one setup to another every time you hear something new and interesting. That way madness lies. Not to mention an empty bank balance! And trust your ears more than internet opinions ('specially mine!) and random forum sonic comparisons, many of which are flawed and produced by people who don't even realise why they're flawed. Definitely don't spend money or doubt your ability to hear on the basis of the opinions of people you don't know and trust, no matter how many posts they have on a given forum.

Enjoy the kit you have without worrying about it until you know what, if anything, it's doing that you don't like.

About the only weakness I can see for your current preamp is that it is noisier than some of the other alternatives. A state of the art preamp could give you a nearly 10dB improvement but if you aren't recording quiet sources you are probably OK with what you've got.

Perhaps you could explain what you mean by ‘location recording’.

Having only omnidirectional microphones available to you (albeit very good ones) will obviously restrict the number of miking arrays available for use.

Is portability an issue for you?

I’m unfamiliar with the Scarlet preamps, but personally have tended to use more esoteric preamps for critical applications such as classical music recording.

These days portable location recording is having something of revolution with availability of the Zoom F series of recorders or, even better, the new Soundevices Mixpre series, which have exceptional preamps as well as a very good headphone amplifier.

Thanks for all your replies, and sorry for my late response.

In short, my query has provoked responses confirming that which I already know...I need to get more recording mileage under my belt. It really stems from being shocked when comparing the recordings made by a friend with his £80.00 Zoom portable recorder thrown down on top of a piano, and that with setting up the gear that I mentioned....there really wasn't enough of a difference in audio quality I felt to warrant the extra expense. So felt a bit crestfallen......

I also have a pair of rode NT1As.

I am mainly recording very small ensembles and choirs, plus experimenting with sampling of acoustic instruments various (piano, trumpet, cello, even pipe organ!) to use as software instruments.

The general rule of thumb is along the lines of the following in terms of decreasing affect on the recording:
1, Material.
2, Performance.
3, Environment.
4, Microphone position.
5, Microphone choice.
6, Pre-amps and other esoteric gubbins.

Assuming you're recording someone else's material then 1 is out of your hands but learning how to get the best out of your performers, the environment and your current kit will pay much larger dividends than any cash investment initially. And it's free. :)
