Not sure why you folks want to keep plugging preamps into preamps? I only do that when I'm forced to do that, such as coming off of active microphone splitters. Active microphone splitters already have a microphone preamp in them. But then it's coming out balanced and microphone level, up 250 feet or more of cable, going into the microphone preamps of my console. Otherwise, I don't see much point in plugging a microphone preamp into another microphone preamp. Unless you have a to particular need for that particular flavor to be combined with another particular flavor you simply can't live without. You're just asking for more noise & complexity in the signal chain. I generally won't plug my API microphone preamp into my Neve microphone preamp or my Neve microphone preamp into my API microphone preamp. Just no reason for it unless I what that kind of sounding preamp when feeding the other preamp. It doesn't make you look any better as an engineer to be plugging preamps into preamps.

Not a thought, just a lecture

the bluetube is a tube pre, and i was plugging it into the firestudio as a line input and the firestudio was just converting it to digital...i dont think it had a pre into another pre

i just wanted to know if the setup i mentioned would cause any latency issues (or any issues in general)

dude I don't really think there will be big latency issues.
That's mainly dude to processing. There is still the same amount of digital processing.
should be no different.
Unless I'm missing the point.

Latency issues with what recording no. Playback thru the firebox, no. So as long as you monitor through the box no. Really there shouldn't be any issues unless you are monitoring direct from the daw and then it depends on your buffer size.

ok cool thanks for the info. Just wanted to make sure this setup will work before spending 1k on it haha
