New equipment from Jan Meier is always an occasion. In the last few hours Jan announced technical details of his new DAC in the Meier Audio Stagedac thread. More information at his website.
Some notable differences from the Stagedac., e.g. looks like careful attention to jitter control; USB up to 192kHz/24bit; a third preamp level up to 6Vrms (useful for those with harder-to-drive amps); AD797 opamps - used in the Classic and IIRC Concerto amplifers - replace the LM6171; and the digital filter modes are no longer exposed.
