Some thoughts on dust covers
You can buy lucite platter covers that have a hole for spindle and handles for lifting and placing for about $60 each, somewhere on the internet. They protect the platter nicely.    
Question about loading with an SUT
Adam, I’ve got two oscilloscopes, an audio signal generator, and etc. I’ve built and modified my own equipment, which includes Atmasphere amps and preamp. Even I would find Atmosphere’s suggested procedure daunting. There’s nothing wrong with foll... 
Question about loading with an SUT
A high gain phono stage can be an MM stage with an additional voltage gain stage tacked on to the input end. Such a topology can therefore handle both low and high output cartridges. Alternatively a high gain phono may simply incorporate a very hi... 
Declare the correct value on the Customs form?
I’m wit’ you, Gris.  
Question about loading with an SUT
You left out “head amps” aka “pre-preamps” which have been around since the early 70s. These devices are active gain stages that boost cartridge output voltage ahead of the phono stage. They do not correct for RIAA. Sutherland and Hagerman make go... 
Question about loading with an SUT
I just realized the 103R has an internal resistance of 14 ohms, as compared to the standard DL103 with R = ~30 ohms. Therefore I have to temper my earlier advice. Setting the SUT ratio at 1:36 would still be suboptimal but not as bad as I indicate...

I’m in.

These days, I advise wearing an N95 mask in any airport and on any airplane. You not only reduce your chances of COVID but also influenza.  
Question about loading with an SUT
The 1:36 ratio with the Denon cartridge gives you an impedance that the Denon cannot drive efficiently. About 50% of its signal voltage output will be lost to ground. So doubling the turns ratio from 1:18 to 1:36 gives you nothing in terms of adde...

Mclinnguy, wait until after Inauguration Day if you want to see tariffs in action. We ain’t seen nuthin’ yet.

Sadly, undecillion hadn’t been approved during my clinical training years. Then I went into the lab and never came out.

Undecillion is also used when penicillin doesn’t work.    
Where's the next weak link in my analog chain?
While I can’t agree that cables are a major key to audio happiness, I do agree they make a difference, and a highly colored cable like Cardas GC is likely to take you in a direction you don’t want to go based on your responses. Also I think cable ...

Art 9Xi and 1200G or G2 would be nice for you.
