@sakso136 Which server are you moving to?
Regarding the new driver break in, I'd check with Cube to see if they ran those drivers prior to shipping to you...as that might be a factor.
They should sound good enough as you have a week and a half on them. You could try higher volumes and a break in specific disc / tracks?
Here is a response I sent to @toetapaudio on my personal experience with break in:
"....Cube, if memory serves me, felt a few hours of runtime would be sufficient.
Jon Ver Halen, the US importer, put it at 40 hours or so.
Based on my experience, I peg it at about 150 hours before the Nenuphar start coming into their own. They definitely started sounding better after Jon's recommendation of 40+ hours. So take 40 as a minimum, minimum...with 150 as my personally recommended minimum.
For 'full' break-in around 500 hours for musical beauty, wonder and engagement.
An industry person I respect and who has significant experience tuning analog gear, felt 1000 hours would be needed. I realize 'hours' of burn-in are a hot topic with folks falling on either side of the divide. I took his feedback and pushed for that 1K mark, after which I consider break in to be complete. However, If I were advising, I'd stick to the 500 hours with folks generally being happy with the results post 200 hours."
