I have obtained a pair (could not find singles) and one of them has sat in my DAC 1 since before Xmas
It leaves the stock one for dead and is slightly better at detail retrieval than my Tesla, although not quite so good at ambient detail. The treble balance is slightly higher but a worthwhile improvement and at about 30 squids for the pair not too bad a price
Yep many Russian valves are great. Older the better
