Have not heard it with the upgrade. I did own the preamp at one time though. Sold it and found a Pr16 that I enjoyed quite a bit more for a number of years.
Also thought about doing the upgrade to my CT 6 before selling it. At the time I was given the same advise that I gave you. But I preferred the Pr16 to the CT5. Won't name names regarding the person who gave me the advise but the company that he worked for had the initials CJ.
