To be fair, me alone cannot really say that the TS 6BE6 would be better than the the TS 6485. A few people heard the 6485 and only me the 6BE6. From my point of view, the TS 6BE6 (EF91/92 setting) wouldn't be any worse than the TS 6485. If you have the suitable cans, I would imagine you could say that the TS 6BE6 is better, or you could say I don't hear a big difference. But they are differently loud, so it is more difficult to compare them than tubes of the same family.
Yes, 6AU6 and 6AH6 use pin 2-7 strap. For 6BE6, I suggest the EF91/92 setting. Hear for yourself. :)
