you are definitely a guy who has tried a lot of gear and most likely researched a lot of stuff too. I am at that point where it’s time to upgrade my Dac the New Ontech Dac 07 a $2500 deal..I keep dragging my feet, I would like to get the Meitner MA3i but that’s a lot of clams. I have been researching the Whest Mastering Buffer model BII, have you researched this or tried it?..supposedly it cleans up the output to the preamp from a Dac or phono stage..the person I talked to said no reason for a expensive Dac..is it snake oil?
