Does BTR7 have dual clocks (oscillators) like BTR5 ?

I need advice, I want to buy either BTR3k, BTR5 2021, BTR7 for convenience but sound quality is the primary consideration. I really hate ear piercing treble, I like the sound presentation of the iPod video 5.5 and Fiio Q1 MKII (kinda warm signature). which one of the above can you recommend me...

I also noticed iPhone audio (through USB) is not as sweet as audio from PC. In using iPhone X ios 13, dragonfly black, FiiO Q1 MKII, odac revB. All sound good on PC but on iPhone the sound is degraded(sounds a little harsh and not as spacious). Did you find why? Or how to rectify it?

After being disappointed in the audio quality from dragonfly black I decided to track down the source of audio degradation. I opened the device (by cutting the housing) and bypassed the headphone amp by connecting an external amp to the Ess DAC output and I was stunned by the resulting sound. I...

I currently have ODAC RevB by JDS Labs I want to use it on my iPhone 6s can I buy aheadphone amp (Fiio E12)? or Audioquest Dragonfly black can be better? my primary concern is sound quality

I googled it and I found a review where they said it has circuit that removes DC offset. I then did measurement (using multi-meter) of DC on iPod output and compare it to amp output (which read 0 mV). I concluded it's safe to remove the caps for E7 and E17 you can try the same (I can't do that...

Hello! after doing some research, I found that FiiO E11 removes DC offset so, I made DC measurement on the FiiO E11 output after removing caps and I found: 0.00mV while the input had 1mV (left) 1.2mV(right).  I removed LOD caps completely and I'm enjoying full quality ( I can notice the difference).

I terribly sorry! I tried to upload pictures but it failed, maybe later on.

That's what I did. I cannot open the LOD cable agai since I have glued it already but that's the cap I used inside it

Finally, I modded my iPod 5.5 and this is  what I did; I removed the caps near the DAC, removed inductors near the dock and routed the signal as directed in this thread, I could not find "black gate" caps so, I took caps I could find on the computer motherboard (47uf 6V) because of their size...
