Anyone drive a power amp from the DI on Trace Elliot Elf or GK MB200? Asking for a friend. Just purchased a PLX1804, ran across a good deal but dont have anything to drive it with (dedicated preamp). I do have the Elf and MB200. Results? Opinions? I will probably end using the PLX for PA but thought I might give it a whirl. I had sold my 1804 a few years ago and regretted getting rid of it.
