How's the resolution with ES-1A compared to 009/S or well driven 007?

You should read head-case Stax thread from start until the end. You can find answers to every question you have there. Bonus:

In this forum people do not care about giving recommendations to new people. Just saying. Head-fi is the place to get recommendations, share your impressions etc. If you want to know more about Hifiman, here you go:

Susvara is slightly behind of Stax Lambda Signature in terms of detail & resolution. That means, 007 is clearly more resolving than Susvara. 009 is significantly better resolving than Susvaras. I haven't listened to any of those Shangri La models. I don't know how to compare subjective mumbo jumbo like liveliness, musicality etc. That's something for you to decide after hearing both. That said, anyone who says Susvaras are better at imaging than 007 shouldn't be taken too seriously.
