And I think that’s what makes it difficult to buy a used OG Pendant. You’d have to ask the seller when it was originally bought, and try to get one as close as possible to late 2020. I think I have the latest OG, which replaced the 300ohm output with 100ohm, and therefore has all the advantages that brings, along with some other changes to reduce the noise floor.
Zach listed some of the OG updates in this post.
The Pendant SE will still be better of course, but a used later-model OG will be great value for money.
