The 210 does not have analogue output or its own DAC. The 218 does. Same form factor. My existing kit is Cyrus 8XPDQX DAC/integrated amplifier + Xpower Power amplifier + PSR power supply feeding B&W D805 D3 speakers. I’m happy with the sound.
As in previous reply I was just trying to get a future proofed reliable way of integrating ROON in to my set up to replace my Sooloos kit. As in any technology I was enticed by MQA as a free feature only to discover it’s not so simple. I like the concept of MQA, but whether I would notice the difference is another thing.
