I have only come here seeking knowledge...

Hi. Just joined Audiogon. In my first search here I didn’t find anything close to what I was looking for.

Background:

I gave up on vinyl when I bought my first CD player back in 1985. In early 2017, I got the vinyl bug again and bought an Audio Technica AT-LP5 based on my research, (the price didn’t hurt either). Overall, I’ve been satisfied with it, however, in the last 7-10 days, I’m hearing a pretty loud hum between tracks. When the new track starts, It either disappears or is masked by the music. Sound is as good as before this hum started.

My Rig:

Tuner- NAD C 427 (2016)

CD Player- Denon DCD-600NE (2019)

Turntable- Audio Technica AT-LP5 with VM520EB/H cartridge (2017)

Phono Stage- Alpha Design Labs GT40a (2017)

Homebuilt Windows PC with Creative Labs Sound Card, and  Exact Audio Copy,

Audacity software. (2014)

Integrated amp- Cambridge Audio CXA60 (2016?)

Speakers- Wharfedale Diamond 240 (2016?) and Wharfedale Diamond 225 on the way for Winter in South Texas. Tried Monitor Audio Bronze 2s (arrived damaged,) and Q Acoustics Concept 20s (one speaker was defective.)

Insight Quest:

Being both retied, the wife raises her eyebrows whenever I bring up the subject of electronics. The newest piece I have is the CD player.

I’m putting money away for a new turntable. Based on what I’ve seen so far, I got it down to two. I’m thinking of either the Pro-Ject X1, or the Audio Technica AT-lp7. I’d really appreciate any help and/or ideas. Thanks!

The big question is "what changed?". You mentioned that you moved things a couple of months ago, but you also say this hum began 7 days ago. So I surmise it was all quiet after the move to the basement.
There is the possibility that the hear wave means dirty (AC/mains) power.
There is a bigger possibility that something changed in the grounding: a loose wire, something you moved its AC to a different plug, etc.  MC already asked - but be aware that you ought to have everything plugged into (logically) one outlet.  Since you need many physical receptacles use a large, high quality outlet strip to break it down (or, as I do, make your own...)
But the bottom line is SOMETHING is not the same....
