Well I guess I will roll my own.
And stamp out a few more PC boards along with it.
Some real world experiences using this for transfers made me think that de-clicking flat material is the way to go.
I also have this strange habit of wanting to look at X-Y vectors as I listen.
Clicks and warp are definitely - more often than not - a Side (L-R) thing.
You see these huge clicks at right angles to the mono line.
That realization came to me late but it makes sense.
A boulder in the highway is going to deflect your car upwards as it hits the oil pan.
The stylus is no different - the microscopic boulder or pit in the groove causes vertical modulation.
We had a reader here make that point for warp.
The vertical mechanical vector is Side.
Once I started capturing some test tracks I realized I needed less gain.
Lots less gain.
The A/D has a +10 dBu dBFS.
Input to the converter was hot.
And those clicks need some extra headroom.
I took 6 dB of gain out of the preamp overall.
This gives with my cartridge and most material about 10-15 dB of headroom on audio, less on major clicks.
I also lowered the RIAA EQ path gain from +8 to about +4.
Along the way I had to figure out how to make Cool Edit's DirectX 9 plugins run under Win 7 x64 DirectX 11.

I just revisited a couple of Steely Dan tunes.
"Ricky Don't Lose that Number" had some bodacious clicks during the low-level intro.
I did a flat transfer, de-click, and then applied software-defined RIAA EQ with an FFT filter:

What I need to do for comparison is record it with RIAA EQ, de-click and then compare the files...
