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!

asvjerry, THAT would be a climb. Nah, I always had trouble with the coach light at the curb, I was lucky to get a month out of a light bulb. I bought an led bulb for it over five years ago and it’s still going. That motivated me to switch the whole place to led. To my surprise, My face does not appear orange in photos 🤣. Don’t want a Finnish basement, too lazy to learn a third language...

In the midst of all this banter, someone else up above was trying to get to the point I think of saying that all your audio system components should be plugged into one electrical outlet, ideally. This is because otherwise you could have been dealing with a ground loop situation, where ground on one of your circuit breakers is maybe a few volts different from ground for the other circuit breaker. That voltage difference can cause hum. This is the reason why you want to plug everything in to the same circuit, and nothing else goes into that circuit.  So If your problem returns, that is something you might think about.

My apologies for mentioning this earlier. I will certainly try that. I’ll see what’s in the market. Of course, I’d certainly appreciate suggestions if anyone can afford the time. Thanks.

@lewm, that could be one answer, but there appears to be 'ho's' all over the board on that.
Personal stuff is running on 2 different circuits here; both with 'upstream' GFCI's.  For a time I had an annoying 'background' *hmmmmm* that started a quest....
Turned out to be a faulty cable with a bad ground side.
Swapping out the ballast on a fluorescent just elimated the *mmmm* of it.

Like Italian sport vehicles, audio is a cruel mistress.... ;)

@badapple, me neither on the third language.  Native english can be misunderstood with the drop of a verb, my spanish is limited and ghastly, and any 'off-planet' ones require mouth parts I don't have..... 

The only LED that I don't like is the streetlamp that's too close for comfort.  I'd slingshot it, but I'm the obvious 'perp' to do so....

Oh, btw....Coming here for knowledge is sometimes asking for a drink....
...and getting hit with a firehose....;)
