Of course, if you’re digitizing records, all you really need is an ADC, like a Scarlett 2i2. RIAA can then be done in the playback program.
Heck of a lot easier to de-click pre-RIAA as well.

Presumably analog, but tbh, it’s not something I tested.Is the overload performance in the analog or digital domain?
I bought the coax output version a few months ago. I like it. I just wish the input cables didn’t stick up.
Re: overloads, the issue isn't just recorded velocities, but also ticks and pops. Morgan Jones did some measurements to look at actual cartridge outputs, and he saw much bigger peaks from vinyl defects than from any signals. Now, if recovery from overload is essentially instantaneous, then no harm, no foul. But I'd rather have the headroom.

The upward cables are handy for access, but, man, do they mess up the aesthetics.
Thanks! Hadn't realized that Shannon had added the "magic" feature (along with a bunch of others), so I did the firmware upgrade tonight. Tried it out on a very beat-up Lou Donaldson Blue Note (BLP 1566) and, while it wasn't exactly magically, it did make it somewhat more listenable.
I also have those same Mediabridge connectors, which do help avoid the weird octopus look...
First up, the noise spectrum, generated with a Stanton 881 as the source:
So what is the 18.5-19kHz spike? Why doesn't it show on the 5mV input spectrum? The input loading with the cart would be pretty close at low frequencies to the gen but becoming a full blown inductor at HF wouldn't it- what is it picking up? An LED/CFL/SMPS on/above your bench? The cart is in a metal box with short leads I guess and I'm sure you don't have nearly 50 things hanging off your power outlet like I do...
So I'm only left with speculation- as you surmised, I have all kinds of things plugged into the same power strip, And indeed at that high a frequency, the cartridge is an effective antenna. The physical placement of the Puffin and cartridge for the retest is pretty close to the same spot, say within a couple of centimeters. Any ideas?
Thanks for doing this, @SIY. @scott wurcer did you still want to play with it next?
That might be fun, I can run the usual set of test LP's. Drop me an e-mail.
I'm curious which test LPs you like...
I've got the HFN and another I'm forgetting...
I have the complete set of CBS Labs STR series, but the best pink noise track is on the CH Precision 45rpm calibration disk. Of course being a 7" disk all the tracks are mostly inner groove. That's IMO an overlooked problem with test LP's, if you want serious precision with a conventional tone arm the radius of the test track matters. The STR series has some sides with tracks repeated at outer, center, and inner grooves AFAIK the only case of this (I might be wrong).
Where in the word did you find those disks?
No I don't.Do you have any of the CBS CTC test records Scott?
