After having Matrix X-Sabre Pro and Matrix x-spdif2 for quite sometimes, I have different setting now. Just sharing what I found. Initially, I am using Async, filter 7, dither On and Jitter Off. I like it a lot as it sounds like my Chord Qutest but better in vocal too. All these changes are relatives too. When i was using filter 7, i am using wireworld starlight 7 usb cable initially but the synergy was too clinical so I bought cardas high speed usb cable then it was better. Then i have not change any settings.
During these Covid-19, I have a lot of times to play the setting and adjust my system. After reading from forum, I change the Async to Sync. Immediately, I hear the change in sound and I like it a lot! It sounds more holographic. I realize i miss so much joy for so long.
Then I am curious and starts to play with all the filter setting. Then I notice filter 6 sounds more natural. Although filter 7 sounds good as it is more neutral, clear and very good soundstage but some songs seems too clinical that I have to turn down the volume. As for filter 6, I don't hear the clinical sounds. When I change from filter 7 to 6, initially I may find the filter 6 is a bit too round off in high treble but after a while, I hear filter 6 is more natural. Then I also change the Jitter On as the vocal sounds better.
I am using piano music to test as I want my system to sounds as real as possible to real piano. Using filter 7, it sounds nice but lack of weight for the piano. Using filter 6, I hear more weight on the piano and more natural. I also use violin music to gauge the filter. The violin sound clean and squeaky using filter 7. No wonder, i need to turn down the volume as it sounds too clinical. Filter 6, i can hear the violin have the resonance from the body of the violin instead of just the string only.
With the new setting, I realize that even trumpet and bass also sounds more real too. Without the weight, although it sounds good for filter 7 but can be fatigue and not so real. With some weight in filter 6, the music sounds more real now. The timbre and tone is more accurate to me now so it sounds more real to me.
