I can whole heartedly agree, that adding an end game preamp was a game changing experience for my system; and I tested your BAT VK-80 preamp....and it truly is world class IMO. I chose another preamp, because the BAT's $10k was a few thousand dollars over my max budget.
I had recently added a couple of great amps (Aric Audio Transcend EL34 "push pull" and a CODA S5.5), and a new set of Clayton Shaw Caladan speakers.....and those were HUGE leaps in SQ; I would say my first "hi fi" and not "mid fi" components
However adding a an Aric Audio Motherlode XL preamp, just made everything nearly perfect. I'm not sure I would have thought that prior to owning the Motherlode, but that is because I had never owned a high end preamp. I am now a believer, for me the preamp was a great addition to any high end system.
I also believe that room acoustics is critical, and will have a dedicated and properly treated room finished by the end of the year.....with dedicated power of course.
