Hello! I'm sorry if this is in the wrong forum. I did a search but didn't find anything useful, which I guess is because not many use the 58A for recording vocals. It fits my voice like a hand in a glove. I've been using a 12+ year old 12 channel mackie mixer (don't remember the model name atm) at least 12 years connected to my faithful old servant M-audio delta audiophile 2496 pci dac and this setup has been fairly noise free IMO. I've never had any reason to upgrade this setup except upgrading my desktop pc but now I think I want to be able to replace my desktop with a laptop/ultrabook and therefore I need an external audio interface. And if I can remove the mackie mixer in this process I'd be more than happy to. I don't need 12 channels, I only need 2, preferably 4. I've had bad experiences in the past with USB interfaces because they've been noisy. I don't want to spend a fortune, top 220 euro (about $200 VAT excl) but noise is the most important factor and it is impossible to get any clues reading reviews (which imo rarely mentions noise) or specs. I only need 1 (preferably 2) xlr inputs with 48V (for when I use condenser mics) and 1 hi-z input, 2 is better. The beta 58A needs a fair amount of gain, which my mixer has been able to provide without adding any noise that surpasses the noise from the m-audio card. So this is the most important thing, gain without noise, so the preamp needs to be decent. I don't NEED to replace my mixer, but it would be nice freeing up desktop space. I've been thinking of a Line 6 UX2, a friend have the UX8 which isn't produced any more and I've measured the noise level on that one and it is really good, less noisy than my m-audio card but the ux8 has external power which I think removes a lot of noise compared to usb powered. Sorry for TLDR factor! Appreciate any input!
