believe the factory installed tubes are JJs. Dont have the 6.5 but do have the 7.5. You may want to try installing some PSVANE T-IIs. most open and 3-D tube I have tried so far.
Thanks for the reply. The tube brand is not in the manual, and have been unable to get the info from VTL, though I'll be buying a pair from them, and will find out when I get them. Was just hoping to find out before purchase.
