To Erich Wetzel,
I read your review of the Rotel RB-1582 MkII power amp with much interest. When will the review of the matching RC-1570 preamp be published? I am interested in the DAC of this preamp for my Sonos Connect. How will its DAC compare to DAC separates such as the Rega DAC, Arcam irDac, or Audiolab M-DAC?
Currently I have the Rotel RA-1062 preamp and the RB-1080 power amp driving my B&W 805S bookshelf speakers.
I obtained an Arcam irDAC to listen to in comparison with the RC-1570 (the review will publish soon). I found that the Arcam would be a superior DAC to that in the RC-1570 if you are looking at simply getting a DAC. However, if you are in the mood to upgrade your preamp to something newer, the RC-1570 will absolutely be compatible with your amplifier and B&W speakers. The RC-1570 will definitely be more current as an integrated preamp-DAC combo, but I am not sure that the sound of the preamp section itself will be better than what you have now. As a result, I would definitely listen to the RC-1570 to confirm that you will be upgrading your system's sound and not just changing it. The Arcam as a standalone DAC will absolutely do a great job with the equipment you have in place already and will give you more accuracy and precision to your system’s sound without being harsh or sharp sounding.
Unfortunately, I cannot speak about the Rega or the Audiolab as I do not have sufficient experience with them to fairly comment. . . . Erich Wetzel
