Fery few multi-bit dac's left really.Not really they are more than ever now, as in the hi-end they're realizing now that to do PCM conversion right it has to be done with Multibit.
Hi-End ones like MSB's flagships, Total Dac, Metrum, Schiit (has upgrades to multibit) Aquahifi and many many more.
Here is the latest from Aqua.
