The Stillpoints ERS can be fixed to the interior of component cabinets and it can also be positioned anywhere without fixing it in place - permanance is not a requirement for use.

Stillpoints ERS can be ordered in different sizes and/or cut to a size requirement. The HARApad is hard acrylic and A'zon comments suggest it cannot be cut.

The HARApad is designed for laptops: "protects the laptop user from harmful electromagnetic radiation and EMF" and "The HARApad uses lead- and tungsten-free, military-grade electromagnetic radiation shielding to attract the extremely low frequency (ELF) radiation emitted by laptop computers." Do audio components emit ELF radiation? Using specific materials does not make the product "military grade".

ERS is meant for EMI/RFI, known issues to audiophiles. The HARApad advert does not mention EMI/RFI.

I have not used the HARApad, but A'zon comments suggest it doesn't measure very well with a Trifield EMF/RFI meter. I'm not saying it does not work, just that there are other options from a well known company.
Tima... I appreciate your post, and suggestion. I already own, sell and use Stillpoints ERS cloth, however it did nothing to reduce this specific problem. Furthermore, it is no longer available in sheets; only rolls.

I also own a Trifield EMF/RFI meter. The fact that the HARApad solved my issue is the purpose of this thread, nothing more. I did my research, tried this product and it simply worked.

Thanks for bringing this product to our attention Ivan. I'm putting one in my cart. Just because I don't have a hum issue today, you never know what tomorrow will bring.

This device: HARApad EMF Protection - Radiation & Heat Shield really works. It will support heavy weight, and doubles as a heat shield.

Simply place this under the component(s) you feel are being adversely affected. At only .25” thick it becomes an invisible shield, and will solve your problem. As long as the hum is not volume dependent (gets louder with your volume/gain control) you more than likely have an EMI issue.
Ivan would this be a good addition to place under my MX150? it has some hum you can hear in the speakers at low levels or when nothing is playing.

However same rig and all the same amps if I am running the 500c 500t Vs the MX150 to drive the 601s it is dead quiet. My guy tell me it is a 60hz hum and the MX150 with all the added cables and maybe not as good of internals as the 500 rig are the issue as to why it picks up the hum.

Also thanks ivan for your time on this post for all of us buddy

Dave... I don’t believe this will help your issue, especially if it is a 60hz hum. This blocks radiated EMI fields that can cause hum.

Have you tried to verify it is a 60hz hum by temporarily lifting the ground to your MX150?

If it disappears, then I would use a Humbuster device.

Yep does not leave, but I think it is the city transformer that is bad. I have very bad line noise in the past year, we are moving soon and that will resolve that issue Ivan.

But this still may help since I am sandwiched the 150 between amps etc. I am going to stage everything different in the next house. So maybe I will be OK.

I have thought about taking the MX150 to my girls house and a 601 just to test, but man that is a lot of work

I will book mark this thread thank you Ivan for the help!
