Been using both the MF X10v3 and the Yaqin Tube Buffers in my Parasound separates system. Recently replaced my Parasound AVC-1800 processor with the Outlaw Audio 990. Having the tube buffers in place adds that tube warmth to my system. I would recommend going with the Yaqin over the MF. You can tube roll, upgrade the power cord and obtain a much better sound out of your system with the Yaqin vs. the MF using the soldered in 6112 tubes, and it's less expensive. Here is a link to a review I did on Epinions about the Yaqin and where I purchased it: http://www.epinions.com/content_312424107652 Let me know if you have any additional questions.
