Ja, Audyssey werkt ook zo.
Maar wat ik mij afvraag, waar is de aanname (DAC UD + 6 analoge interlinks = beter dan DAC SR + coax) op gebaseerd?
ron
Ik heb een 5.0 setup, dus max. 5 analoge interlinks. Ik meende ergens gelezen te hebben dat de DAC van de UD7006 beter was dan de SR7005. De UD heeft een 32-bit Texas Instruments PCM1795 en de SR7005 een 24-bit AKM AK4358 DAC.
