Roberto so I'm assuming from your signature that you are using the Apple Mac Pro for the Source into the DAC? And are you using Roon?Just before had the Exasound E-32. And before and still with me an Audio Research Dac 8. This new DAC belongs to another level. It is a jewel to use. My ears are very happy with the amazing results.
I'm willing to give the HoloAudio May a try to see how it sounds in my system. Was really looking to go with the NAIM NDX 2 Network Player I demoed but I'd be willing to check the Holo out first.
