Primare,
Yes, I reduced the volume at the pre to compensate for the 6db boost when testing. However, given that the output of my SACD player has been reduced and my pre is passive, the 6db boost merely gets me back to the output level before the mods to my player. It you're worried that the 6db boost would be too loud for your system and settings on your pre, contact Burson directly. While shopping for the buffer, a Burson rep told me that the 6db boost is adjustable to zero gain (or unity gain). Since I didn't have the buffer at the time, I didn't ask for specifics on how make the adjustment, and after I got the unit, I didn't feel the need to adjust the output, so I never followed up on the adjustment. The rep was very responsive to my inquiries and assured me that they would assist whenever needed. I hear you on the volume control adjustment on the pre. I would try the Burson in my system to see how it performs and then make any adjustments. And you might drop Burson a line for answer your questions
