I was all set to get the 950/7100 combo from outlaw audio and they discontinued the 950. Now I'm going with the 990. This is my first pre/pro and amp. I always used a reciever and I never had to deal with balanced vs unbalenced connections. Can I use the 990 with the 7100 amp even though the 990 has balenced inputs and the 7100 doesn't? Thank You for the help.
