I too have the little preamp from SP.....The last 2 shows I tried to record with it I got a lot of brickwalling...one loud..one not so much....Been tempted to get one (9100) from CA to see the difference...but unfortunately de fundz are low....Got a 3 wire batt box to run between the mics (AT 943 and 853 ...both 3 wire trs) and pre but haven't had a chance to test it at a show yet.......
Both Chris's are very nice to deal with but Chris from CA is a regular here and he has many happy customers (here).......Chris from Sp also posts here from time to time but not nearly as often as Chris from CA
I hope this makes sense...I ran out of my pain meds
and have had to resort to drinking heavily
..
Peace ,
