This is my third audio interface. I previously used a Black Lion Audio Signature Digi002R, then moved on to a Universal Audio Apollo Duo. The Avid HD Native and Omni combo is in another league. I use it with a quad core i7 mac mini and it works flawless. I recently recorded vocals on a session with 80+ tracks and experienced no hiccups. Sound quality is amazing compared to the interfaces that I have had before. I record at 128 sample buffer @ 48k and there's no discernible latency. The preamps on the omni sound great as well. Way better than the pres on the Apollo and my BLA Digi002. I was hesitant at first because of its price, but as soon as I recorded vocals through it, I realized that it was well worth the buy!
