I agree with above sentiments.
If you are interested, I got my XLR to RCA cables at Guitar Center. I avoided the "Monster Cable" that I suspect you might be referring to for $60and opted for a less expensive one that is good quality and built nice. I think it might have been a HOSA brand or something similar. I recall that they were less than $20 each for a heavy-ish 3' cable. (I needed four and it did not break the bank.)
