@roxy54 ..."he dropped it to a 9. I think that the best that you can call an amp of that age is a 7. What do you guys think?"
Functional condition and age matters too, not just appearance for ranking. It also depends on whether it’s been updated or not with 34-40 year old caps, and other updates. A local gent partially guts the amp, replaces caps, all wiring, bits and more at a cost $. While the SA 1,2,3 "E" Series can be interesting, some of the same owners also upgraded to Pass X150+ amps later on. Worth reading up on with other Threshold-Pass owners. The desirability may be more of a personal thing, and for me, I’d want to consider the upgrade costs as part of the total investment or perceived value of paying extra for an E series amp. All part of your own personal scoring and ranking for consideration.
