Hello,Am just brought an E30 with the (S/N:2101)
Would love to know if it has an AK4118 or a CS8416?
From what I had read before this thread,it seems to works fine in 44.1PCM from my BW-BR4 bluetooth receiver spdif out,just the volume is a bit low.
Haven't tired it on my laptop on-board spidif out tho
Here's what I understand:
The 1st two digits of the serial number are the year of manufacture, So S/N:
20xx... is 20
20, SN:
21xx... is 20
21
All E30s with S/N beginning 20xx... will have the AK4118.
According to JohnYang, (and he wasn't 100% sure at the time of writing), but
any E30 with a S/N below 2103xx... should have the AK4118, and anything after 2103xx... will have a CS8416.
As I said though, he wasn't sure where the exact S/N cut off was.
I guess the best test is to hook it up to a stand alone cd player via digital coax (not a blu-ray player, dvd player or cd drive in a laptop)
and see if it plays a cd without intermittent sound break up - that was the fault I got with the CS8416. This wouldn't be totally conclusive
as you may still have a CS8416 inside your e30 that works with your cd player, but I think it's a pretty good test without having to take the E30 apart.
-that's what I know. This bit is now a guess:
if the 3rd & 4th digit of the S/N is the month of manufacture, then you might be ok with your S/N 2101 as (if I'm right) that'd be January 2021, and I don't think the change happened until around March (S/N 2103) - that's if my guess about how the S/Ns work is correct.
