The pandemic has been very good for the audio industry as a whole, they are getting record sales. So many popping up taking advantage of this or the ones that were smaller are now larger due to larger sales etc. i suspect it will deflate soon enough as the pandemic come to and end and people start doing more out side their homes.
The vintage market has been especially crazy with silly prices and that's going to crash soon enough. I suspect. Hopefully not as I've got a bunch of stuff I'm going to be unloading soon lol.
