I compared the VX to the 64 Audio Tia Fourte. I felt the bass was better on the VX and a bit smoother Highs ( I was using Cayin N8 in tube mode by the way). The Fourte is a great IEM, but that treble can get sibilant fast, especially if you like listening to Adele. I also compared to Custom Noble Encore and the universal VX had equal or better bass, a nicer midrange and both had excellent treble. I would say the VX was a bit more detailed without being sibilant in the treble. I love my Encore, but the VX was better. I would not make this switch though if only universal was offered. I expect the improvement to grow once I have the custom as this is what occurred with the Encore. I also then tried increasing the bass on the VX and this was interesting. I did not have time to stay all day and listen, but the controls on the VX might actually be valuable. We will find out once I own it. I compared to the Khan as well, though I had returned these already. So this is only memory, which is never really reliable with music. But as I felt my Custom Encore was right with the Universal Khan, the VX was more musical in the midrange and did not have any noise when connected to my iPhone or Dragonfly Red as the Khan did.Cool, thanks and good to hear. The inability to try them out is a little bit disappointing but the feedback from impressions and reviews has been pretty positive so far. Unfortunately it sounds like they're not going to Axpona, Canjam Socal or RMAF this year so a demo for me won't be possible. Just curious which TOTL IEMs you compared the VX to?
I also tried out the VE 6 ( the VE8 was not there to try). I was very impressed with this IEM. I felt the VX superior, but I would like to someday test their new top of the line universal. The AAW Mockingbird was also available to test, but I was not a fan. It just did not have the bass impact to even be considered a competitor to the VX. I like tight impactful bass when the music calls for it. The Tia Fourte had much better bass than the AAW. I own the Fourte, Andromeda and the Encore. I did not have the Andromeda with me at the time though, which is why I did not mention it. In the past I have owned the Shure SE846 and the Westone W80. The Fourte, Andromeda and Encore are all superior to both of them which is why I do not own them now. I hope this helps you a bit with your decision.
