recently noticed issues with my xlr in's on my Eden WT-1000 power amp. audio is faint. need to crank up the volume along the signal path just to get a decent level from the amp. when i use the 1/4" in's, all's well. no problems. anybody ever run into this problem with their eden power amp? am looking for a local repair shop to check on it. or is it a 'simple' fix that can be done at home? any help is appreciated. thanks!
