Mic very close to speaker, yes?

Yes, the usual - about 9 inches, but not the usual mics.

And not directly in line with the

tweeter.

Correct - about in line with the bass units. (It was the *slam* I was
after!)

This the first mic recording of yours where the direct

recording has been brighter than the mic recording. So I'm guessing
you used the IMFs and a pair of cardioids, if not the ribbons.

Yes, the IMFs and my (cardioid) CAD GXL2400s - rebadged OEM Shuaiyin
mics which were cheap and which I use for 'dirty work'; not the ribbon
(also rebadged Shuaiyin) - I only have one of those and I wouldn't
subject it to that sort of behaviour!!



Dynamic range is good for vinyl at about 50dB, but there's still
better than another 40 to go before you would start seeing a CD
sweating.

That's *on paper* - anybody/everybody knows you get much better *phat*
slam in the real world from vinyl!! (This is about *sound* - not
*signal*; you can forget the figures when it comes to hosing the actual
noise about..!! :-)

I'm not sure I know what phat slam is, but I know what small changes
to frequency response sound like.

A few years ago I spent ages optimising the loading of my Shure V15/3
and the flatter the response became (within fractions of a dB,
measured with a test disk) the more it sounded like my CD player with
the same album. Very close in the end. So if your AKG cartridge
sounds very different from a CD player it is probably not very good.

I was never able to get the bass as punchy from the LP though (I think
LPs are quite restricted at low frequencies to avoid mis-tracking) and
of course there was always the crackle and pop in the background.
