For mechanical relays I use the Axicom D2n*. https://www.te.com/commerce/Documen...hENG_SS_108-98007_H_D2N_0614.pdf8-1393792-5
But there are a bunch of good options: Panasonic, Takamasawa, Omron, etc.
That relay has a minimum recommended contact load of 10mA, which is far more than you'll normally see in audio. The one I've linked to has a more useful 10µA minimum load, its not relying on arcing to clean the contacts of oxide build-up (I presume because it has decent thickness of gold)
