Thanks guys, I will try those, price is very reasonable... telefunkens are 400-500 USD on ebay for ‘matched’ pair...
I’m very curious (regarding all positive comments here) about ’75 voskhod 6n23p also; price is ‘round 100 USD on ebay …
Did you hear ’75 voskhod on your systems? Can you tell me difference between JJ’s and ’75 HG?
What’s bothering me (I have HD 650; pretty warm, thick sound+ MARANTZ SA player - also very ‘warm’ sound) is: will get some clarity and space, more details with those tubes.
When I played ‘easy’ jazz on this system (with stock Russian tubes) sound is very pleasant, but when I put some classical music- all ‘picture’ become very blurred, ‘heavy’…
Or should I just buy HD800 for classical and more dynamic music?
