Changes in DAC Presentation - Need Advice
Hey all, I recently purchased a Denafrips Terminator II, and ever since I've noticed that some days the sound is sweet and natural, and other days it is forward and bright. I've even heard the sound change mid-song. Could this be due to fluctuations in my line voltage? Any other reason this may be happening?
System:
Mac Mini running Roon core
Sonore ultraRenu
Denafrips Terminator II
Pass XP-12 Preamp
Odyssey Audio Kismet Monoblocks
Focal Sopra 2
+1 @lordmelton Break in period can be "interesting" to say the least. My tube amp was so bad at time I just had to leave the room cause I couldn't stand the sound. I would think the Dac would be as bad but it will be noticeable. OTOH, it "might be changing filters", as @mahler123 suggests. Problems with new electronics tend to show themselves in the 1st 3 months IME. |
I have a voltage regulator on my line and notice a fluctuation of up to 10v. It is rare that it will fluctuate more than 1v in a short period of time. For a significant increase in voltage to occur, either an auxiliary power supply we need to go on/off line or a huge number of people would need to do something simultaneously. Not sure this is terribly likely. Could be break-in, especially if it is going in the same direction (bright to warm or Warm to bright) every time your hear it change. Do you notice a difference if the system is on for a while prior to listening or if your turn the system on fresh? Another obvious spot to look is the weak link in your audio chain which is that Mac Mini. I talk to lots of people and more often than not, if something bizarre is happening in their system, a Mac Mini is involved. Does anything else run on that Mac Mini? If something else is taxing the processor, that could be your issue. It would also explain why you might hear a change mid-song. |
@verdantaudio, my system is on 24/7 so I can't imagine there is much warming up as I listen. Regarding the Mac mini, nothing else is running on it except for Roon, but I'll definitely do some research on this. Thanks! |
@sbank, the OS/NOS light does not change. |
I have a T2 + upsampled you didn’t mention how long you have had it it takes over 600 hours to fully stabilize with these OX over clocks ,one reviewer in Europe documented this , you are supposed to not shut it off , or putin stand by , you should have a dedicated 20 amp line if possible . Are you in the u.s ? If so look up my user name and send me a message 8 can fill you in ,and you can tell me what you have or din5 have what kind of line conditioning, and usb cable ,if using a computer buy the Iris, or Hermes reclocker ,then you can run it direct the best I2S |
