Boulder’s Sales Manager, Steve Huntley, says that the DAC section inside the 866 is largely derived from Boulder’s flagship 2120 DAC which uses a fairly uncommon delta/sigma DAC that requires a lot of external circuitry support and is not one of the usual ‘plug and play’ DAC chips that most companies use. Boulder also uses an external digital filter of its own design, rather than one of the ‘off-the-shelf’ filters built into the DAC. "We use this DAC chip because we wanted to create a truly optimised DAC section and are not afraid of the complexity required to implement it ourselves," he said.
Lumin U1 Mini or Lumin T2 with Boulder 866
Despite Boulder 866 being a Roon endpoint, wanted to add a network player with many streaming protocols. I honed down on Lumin with just one advice needed. Should I go for just a transport (U1 Mini) or a streamer with DAC (T2). Those with a Boulder as well as Lumin might be able to shed some light here. Is T2's DAC superior to that of Boulder 866 or the opposite, in which case I could save some bucks and go for Lumin U1 Mini.
