Hi,
I don't want to get into either side here but I'd like to know the opinions on the ECC802S, which as far as I can see is a somewhat SQ version of the ECC82 (12AU7).
Using my "leet" paint.net skills I overlaid both ECC802S and ECC82 curves with transparency etc, lined the scales up, and they seem to be very similar.
Does the 802 have some sonic qualities that differ from the bog-standard 82? (I should point out that things like 'sound stage', 'muddy', 'tight' and other terms I see around here mean nothing to me! )
I'm thinking of using an 802 in a driver stage, and they're not a great deal more expensive than 82s so I was wondering what the differences really are.
Cheers

difference (guaranteed) is just longevity ;
every other difference is just random (all that mambo jumbo fifi things)
Morgan Jones test summary
Scroll to page 189. 20 Vrms, so scale by about 10% for 2 Vrms. 12AU7 has higher overall distortion at all levels and greater proportion of higher-order harmonic distortion than 6SN7 family. Can 12AU7 sound OK at 2 V? Sure. Better than most solid-state designs probably. Can 6SN7 be audibly better still? Yep.
