I'm always surprised that the PreSonus Studio 68C is not on a list. Usually the lists include one or two PreSonus interfaces on either side of the 68c price point of 300 dolla. The 68c is a very nice interface with an I/O layout that is very desk friendly, and it runs on it's own built in power supply, no load on any USB and it has a power on/off switch! With stepladder led front panel metering for gravy. Works for me, it is one or two on my list, the little Focusrite Scarlet 2i2 is nice too, more portable for iPad use, sounds great, yada yada. I like 'em both and they work together so well in an aggregate setup.
I think if I were to step up it would be to a Focusrite Claret
Have you considered using a "Cloudlifter"? I am curious to find someone with first hand experience with one. Seems like a good idea, except for when it doesn't.
I believe that if I got another interface
(not happening, the ones I have sound better than I do) it would be some kind of Focusrite Clarett.
@Many Moons uses some kind of Clarett and it sounds great to me!
I have a cloud lifter.
Used it for years on my sm7b
Sounded good worked great!
It's not in use at the moment.
Keep in mind........the cloudlifter uses 48v phantom, power to boost the signal so, you need to make sure the interface has phantom power on the channel you intend to use.
I'm now using a RME Fireface UFXii with 75db of gain on the mic pres.
Stepped up from a Focusrite Clarett (which was very good)
Some interfaces fall short of that requirment and come in around 50 - 60 db of gain.
The Cloud Lifter provides an additional 25 db, so it's a great tool if your interface is lacking gain.
Aside form the gain on my interface, I also use an external Pacifica preamp for my main vocal mics and guitar DI.
That unit has two preamps with 72 db of gain.
Even the SM57 & SM 58 need a fair about of gain from the preamp.
I think they need around 50 - 60 db, so if your interface only has 50- 60 db of gain , you're really pushing it to get what you need and very likely introducing more noise in the process.
When asked for my opinion on interfaces, I always recomend checking the preamp gain specs, but many people think they can get by with low gain........until they figure out that need more and they are dissapointed.
Do your home work when shopping, more gain is usually a good thing.
The cloudlifter is one of a few such in-line gain boosters that can save the day with low powered preamps.
