Both these tubes offer an improvement over regular new stock 6SN7's, however both are left in "the sonic dust" by NOS Tung Sol Blackplate Oval plate 6NS7's. They offer sonic beauty and give the illusion of sounding just like real music. If you want details on their sonics go to my review on the Flora preamp when I put these tubes in.
They are very hard to get and are not cheap by any means, but there worth every penny you would spend on them. You might contact Brent Jessee to see if he has any matched pairs for sale.
