Any other companies like Schiit and JDS that offer modular desk-top boxes?

Trying in vain to put together a desktop setup and wonder if you guys can recommend any companies besides the two above that sell little boxes that stack well and have small footprint? Need DAC, headphone amp, phono stage at least. I am probably missing out on a bunch, but seems like this would be in high demand. Thanks!
