So i got the brick the other day and i only had a chance to work with it at a freinds studio since all my gear is on location where I am doing recording for a band. We ran an AKG c1000 thru the brick on acoustic guitar and on vocals. We ran the signal straight from the brick into his aardvark and also thru the board into the aardvaark for additional gain. We also ran the mic off of the Behringer board and the aardvark pre's for a/b comparison. The results: wow. The vocals came out silky smooth with much detail across the highs and lows. It sounded like it was mastered already compared to the other takes. Also the response seemed much smoother overall. There where less spikes and peaks in the EQ and the tone was alot richer. On the vox there was NO comparison really. On the acoustic, there was less of a noticable difference but it was definately different. The board pres seems to have and odd character in the high end that stands right out and captures my attention at first but begins to drain on the ears after a few minutes. the brick was much smother overall had more depth and warmth to the low end. After one day of tracking i must say the brick sounds awesome, but there are several things i dont like: 1 no pad. 2 no output gain just tube gain. 3 55 dbu of tube gain and i was still recording at -12 or so( i like to record hotter) 4 with limited features and only one knob it sounds the way it sounds and thats it. good thing it sounds awesome. for the record this is my second outboard pre along with my cheapo PreSonus tube pre and the pres on my Mackie board. im also wondering if this pre made a $200 condensor sound like gold i wonder what it would sound like with a BLUE or AT 4040 or better yet a Neumann (which i cant afford).
