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!

I’m sorry, I meant platter. Far as I can tell, it’s made of aluminum but was hollow on the bottom.

I used expanding insulation and trimmed it even with the bottom when it dried. As far as electrical, I used to have a large tv with a 5.1 system years ago where I have my audio things now. Never experienced anything similar. Mitsubishi tv, Pioneer Elite processor, Klipsch speakers, several dvd and bp players.

Check to see if the hum is/isn't there when the tv, refridgerater, etc. is on/off

The only thing that’s changed, I moved my audio equipment to the basement a couple of months ago 

Everything plugged into one outlet?

Thanks. I just tried that so it wouldn’t be on my mind. I was lucky that the general contractor, (must’ve been an electronics junkie like me😎), suggested separate breakers for areas where I pictured electronics placed. He also installed a breaker box with eight extra breaker slots for when I finished the basement. Don’t laugh, but I’m using a tv antena installed in the attic in 1994 for the tv in our bedroom (1080p/Fire stick) and the tuner in the basement. About thirty miles across the lake from Chicago and great reception!
