For the hum, make sure the TT is not close to one of the speakers. Mark Mark, Thank you . In my current setup the speakers are very close. About 2 feet or less from the TT. I'll move them further in the weekend and see the difference. This worked for a friend of mine. Let us know how it goes for you. Mark

Let us know how it goes for you. Mark My TT is almost a foot away from my tower and I’ve never had a hum from it. My speed control box is at the maximum distance away from the TT as the cable will allow.

You won't get HUM because a turntable is too close to a speaker. You get HUM when the turntable is too close to a power transformer or a power line... Or when the cables between it and the phono preamp, or the preamp itself, are too close to one of those... Hum is the 60 Hz power line frequency leaking into the cartridge or some of the preamp circuitry - which is quite sensitive to it. You can also get hum if there are grounding issues between the turntable, the phono preamp, and your other gear.
The reason that phono gear is sensitive to hum is that the signal it's working with is about 1000x lower at 60 Hz than a normal audio signal. The cartridge puts out a very tiny signal - to which the phono preamp then applies a HUGE boost... And, because of the RIAA EQ curve which is applied by the phono preamp, low frequencies are boosted even more than high frequencies... As a result, if even the tiniest amount of hum, or other low frequency noise, gets into that system, the results tend to be audible.
What you tend to get if the turntable is too close to a speaker is usually some sort of acoustic feedback... The sound from the speaker causes the turntable, or the surface of the record itself, to vibrate... This vibration is picked up by the cartridge, boosted by the phono preamp, and ends up coming out of the speakers... Basically, the combination of record and cartridge acts like a giant microphone... picking up vibrations from the air.
Those vibrations are picked up, amplifier by the phono preamp, played through the speakers, and the cycle repeats itself...
The sound can come directly through the air, or the floor, or whatever your turntable is sitting on...
Depending on the exact situation the result can be anything between a roar, a howl, and a scream... But it is rarely a steady 60 Hz hum... And the solution usually involves mechanical isolation...
Isolation from airborne vibration usually means moving the turntable further from the speakers...
Isolation from vibration in the floor, or whatever the turntable is sitting on, usually involves things like isolation feet, and noise-isolating shelves...
Welcome to the joy and the challenge of vinyl reproduction.

Post your latest purchase that made a connection that you did not expect. Go beyond what was latest. How did it impress you in ways you didn't expect. This Canon 7D for me has.

Thanks Nic.. the Zunsp we speakers arrived and I'm happy so far. They were burned in for 100 hours prior to shipping. The bass is great. Mids very real.. especially vocals. Drums are amazing.. music featuring great drumming shines. I did a capacitor upgrade to a Jupiter, and the highs are very relaxed.
These speakers are supposed to play well with anything.. but I listen to mostly jazz and acoustic stuff.. these speakers handle this genre reallu well.

How interesting. I had to look this earbud up. Turns out it's a mono only headphone with a frequency response of 100hz-6khz. It must be an older model. What do you plan to do with it?

My barely 2 year old Asus router died the other night, so I purchased the Tp-Link M4 Deco "mesh" WiFi system yesterday.

Do you think it can handle a large amount of smart home devices? Oh dear, I just read that the terms of agreement allows them to collect all your browsing history and credit card activity and sell it to their third party companies.

IF you use their cloud service, and if you have a couple of other features enabled, that may be true. I don't think it is an issue otherwise. Plus I highly doubt they would be looking at anything I do.
With that being said, I am actively looking for a VPN and/or firewall hardware solution to run between the Tp-Link and the modem. Any thoughts or suggestions would be greatly appreciated as I've never really looked into VPN/firewall solutions until I got this new WiFi system, knowing that it doesn't have a built-in firewall.

This is a router which means all your internet traffic goes through it, a much greater breach of privacy. Google, amazon etc, it's only what goes through their services or cookies. I may be wrong as I only saw it mentioned in the reviews and I don't know the extent of the details. But this is a lot more scary.
