Used f10 M5 hifi

[ds666]

Looking at buying a used f10 m5 . Why is it hardly any for sale have anything other than the std stereo ? The one I tested had the HK upgrade which I thought was good . Is the std system ok ? Is the B and O very good ??
I always enjoyed the logic 7 in my e60 m5 , how does a std F10 system stack-up ?
Any feedback appreciated .

Can personally vouch for the setup, having had it in my E70. Mindblowing.

Thanks for that link , very interesting .

I think I need to listen to each the options to see if it is worth searching , or just basic plus aftermarket .
