You should note that the MF buffer has only unbalanced inputs/output and may be an issue if you are using balanced connections with the BAT preamp. I use the buffer between my Arcam CD23 and Placette active line stage (using VD Nite interconnects) and it sweetens the midrange a bit. Also makes the sound a bit easier to listen to...less digital. Music Direct has a good return policy and I believe that unit is on sale right now.
