I have found that the pre90, in my system, renders many recordings beautifully transparent and many other recordings thin and brittle. It seems that swapping op amps might be a solution. Has anyone done this? If so kindly report on your experience.
Does the pre90 remote work well on yours. Mine, as reported by others in reviews, works poorly. I wonder if this issue has been fixed in newer production models.
Just a follow up of using the tube buffer with the PRE90. I changed the stock Tungsol tube to an Allen 12au7 and the noise floor is dead silent now with a nice balanced sound. So you can have your cake and eat it too! I have a Psvane Art series 12ua7-s on the way to compare. Let's see what it brings to the table?
