Eleven Rack's Mic Preamp

[XCorrupt]

Hey guys, I was wondering how the 11r's mic preamp is. I am thinking about using the eleven rack to record vocals and acoustic guitar, so would the 11r's preamp be good enough for good recordings? Or should i still get a tube preamp like the presonus tubepre (I dont have that much to spend on a preamp)? Also, taking into account the new expansion pack that is coming out that has additional vocal processing addons, will the 11r be sufficient to record good quality vocals/acoustic guitar or should i still get a preamp?

Thanks!
