Two versions of commercial Aleph 3 ?

[Sony]

I now own two commercial Aleph 3 that have some differences:

1. The aluminum chassis of the older is true black, exactly like Pass Aleph 0, while the more recent one is a sort of dark violet (uncoloured?). The recent one also seems more polished.

2. The led on the older is blue and fades away when disconnected (like Aleph 0); the led of the more recent is bright violet and goes off instantly (like vulgar amps 😀).

So, these seem to be different versions.

Should I expect other differences - design, parts, ?

Thanks and regards

There was only one version.

Perhaps I should clarify - the circuit never changed, but there
were pc artwork revisions.
