I too use a laptop in my main system, no isolation as it just sits on a glass shelf. An external hard drive where music files are stored is connected to the laptop. No complaints so far.
I have isolation for all my other equipment and speakers.
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?
