Very interesting thread....Thanks...
Higher End DACs
I am looking for a DAC (potentially streamer&DAC) to be paired in a mcintosh system (c1100/611). Its my first foray into digital streaming and I have no need for a CD player.
I see a lot of love for Esoteric, however, most seems to be around their transports? Are they not as renowned for pure digital streaming and/or standalone DACs? I see DCS (for instance) often referenced for standalone DACs - how does Esoteric compare?

Or do what I do and stop the RF at it’s source (coming in through the windows from outside) and turn the entire building into one giant Faraday cage. Problem solved! 🤗 it’s not that difficult. Furthermore, while not widely known, tiny little bowl resonators are effective in normalizing pressure zones in the room for acoustic wavelengths AND RF wavelengths. They’re Two! Two mints in one! 👯♀️ |
@geoffkait I considered the problem as a DAC being an antenna. I analyzed the DAC outputs while the DAC and device-under-test was in a Faraday cage. So it’s quite clear that when a generator of RF is even just proximate to a DAC (no connection) the outputs of a DAC are affected. This means the energy gets inside the DAC. And I have the corollary that when the energy bis there (even a high MHz) the sound is less transparent. So the DAC’s designed performance is affected by: - the xtal clocking the output is perturbed - the multiple harmonics at MHz affect the noise floor in the audio band - reference voltage levels disturbances None of this is measurable directly. The audio band (to 21khz in my case) shows no added jitter or noise floor changes to 150dB. Even in my conversation with Rob Watts, he says he can see nothing to 190dB. But we’re talking High End DACs here...where these effects are plainly audible. |

How do you account for the fact that you consider the affects "plainly audible," but can’t show that with measurements? |
