Schiit Mani - Sent in for repair, no response. Looking for rec's on a replacement preamp

Hi Everybody - first time posting here.  I've run into a serious issue with Schiit.  My Mani ran into a hardware issue (dead left channel).  I mailed it to Schiit on July 3rd, they received it on the 10th and emailed me confirming they had received it and would get back to me in a few days, but to no avail.  I've emailed them a couple of times and just called their number and no response.  I'm getting the feeling I'll never receive my Mani back at this point and I'm not sure if I have any legal remedy to get them to respond (at this point, I don't understand why they didn't just send me a replacement unit). 

So I started looking for a replacement phono preamp.  I have a VPI Prime mounted with a Nagaoka MP-110. Budget is set at 500ish. Any recommendations that will wipe the floor with that piece of schiit?

Thanks in advance,

George
