Isolation Feet for Laptop


It seems fairly common knowledge that vibration is a form of distortion in many electric components, not just for turntables and speakers. Isolation feet seem to work well in most applications.

I searched around and I didn't find any information to suggest that folks are using isolation feet on laptops or desktops, despite increased streaming usage. In a great many cases, there are indeed heavy vibrations coming from within the computer.  Whether it is the fan for the CPU or even GPU to the all the various chips/transformers, etc or even power supplies and batteries. If adding isolation feet to a streamer, DAC or power supply makes sense, then wouldn't it also make sense to apply isolation feet to your laptop; if you use it for music?

Well, I am going to find out. :)

I ordered some IsoAcoustics Orea Series Audio Equipment Isolators with a max weight of 16 pounds. The laptop weighs about 6.7 pounds, so it shouldn't be that much strain, even with all the cables creating some measure of down force as they dangle over the edge.

My expectation is that the DAC will be able to perform slightly better due to reduced vibration across the USB port and power filter. The DAC is a USB stick (Dragonfly Cobalt) so it has a very rigid hard connection to the laptop; so vibration is very easily transferred.

Has anyone else tried this?

LOL, you have to have an actual valid point to have an argument.

Sorry, insults aren't a viable point of view in a discussion. But hey, c-ya.

I don't have a fan noise issue. More like, fan vibration that vibrates throughout the entire laptop and reaches the USB port where the DAC is. Vibration has a negative affect on electronic output. Dissipating or reducing that vibration can increase electronic performance.

This is why people are putting isolation feet on their standalone DACs, Amps, Preamps, Streamers and other electronic equipment.  The computer is just another piece of sound equipment.

Guakus, your point is well noted.

I have thought about this earlier, to use some kind of isolation for the laptop. However, the laptop is too light for most isolators to work. I have some unused Finite Elemente Ceraball and Nobsound springs but didn’t try them under the laptop as it’s too light. I tried the Nobsounds under the DAC and the DAC is also too light for the Nobsounds to work. I end up with 2 units of FE Ceraball under the DAC with the stiff power cord lending some pull/balance to the unit.

Just when I think I've read something that is the silliest thing ever in audio, along comes something sillier.

 

Could someone explain how vibrations are transferred from a laptop (or any other source) to your pre-amp then to the amp (or integrated for us low-fi heathens) then to your speakers and be audible, using science and measurements, not "I know what I hear"? Preferably supported with studies and/or blind tests.
