Original owner. I use this CMA600i as a headphone amplifier. It a beautiful piece of gear and it sounds great. This amp has a lot input output options like analog RCA XLR inputs, single end and XLR headphone outputs, RCA preamp output. Digital inputs include USB toslink and AES. I don’t use its build-in DAC but please be aware that because of the CMA600i’s firmware support issue, its USB DAC input has compatibility issue with certain MACOS, Linux OS and Windows 11. So if you want to use the build-in DAC and only can use USB to connect to it, please look elsewhere.

This is a high-end desktop headphone amplifier/DAC. Do a Google search to see how positively reviewed it is by many audiophile publications/websites. It sounds amazing and is built like a tank. Its spotless and it comes with all accessories and the original box. Im also including a new, unopened, audio USB cable.
