The drop for the Massdrop version of the THX AAA headphone amp goes live March 1st at 6 am. This may sell quickly so you might want to register if it is something of interest?
It’s powerful (2 x 6W at 32 ohms) and quiet (136 dB SNR) with a record-low THD of -140 dB at 300 ohms, 100 mW. That’s four times the power of the Objective 2 amp, for example, with far less distortion. Massdrop x THX AAA 789 Headphone Amp
