Got an SPL Phonitor Headphone Amp w/24bit/192kHz DAC (Black)
Plugged everything in and powered the system up with a brand new pair of Sennheiser HD-660s.
Smoke started pouring out of the top vent on the SPL Phonitor and as I reached over to unplug it,there was a tremendous POP in my left ear that blew out that channel. A cap exploded and destroyed the headphones. My left ear rang for a half hour. My retailer replaced the Headphones with an open box unit. The SPL Phonitor was sent back to Germany. After a year in service with SPL, my retailer
gave me a refund. Complete scary nightmare !
