Sabre dacs versus other dacs

Like nonoise says, it's all in the implementation.  You ask about Mytek.  IMO, poor quality low cost power supplies.  Analog chips.  At their prices, not for me.

One can give you the facts. But if you have beliefs that are generated by high retail prices you are at the mercy of the manufacturers.

I was writing about the Mytek Brooklyn+ which retails for about $2400. Though Mytek gives its products a USA cachet*, they are manufactured in Poland. This $2400 DAC has a switching power supply, much more inexpensively implemented than a linear one. In fact for best perfomance the manufacturer provides a power input for an expensive linear PS and one reviewer insisted that to hear it at its best it was necessary to listen with his $1000 linear supply. Also, Mytek does not use the latest Sabre 9038 chip (as, for example in the later Oppos); they use the 9028. And IIRC they use ICs in their analog section, not discrete components. That is a cost saving choice, and likely one that impacts unfavorably on SQ.

*They name them Brooklyn and Manhattan, not Śródmieście or Mokotów.
