Also consider the Sennheiser IE 8. It has prodigious bass and a surprisingly "open"/"spacious" sound for an IEM. The low end was a bit much for me, but it definitely made for a warmer sound.

You should be able to get into a UE4 for around $500.  Solid choice in a CIEM.

Has anyone heard the Tzar 90 and 350? I'm curious about the 350 specifically because it's supposed to be neutral and all plus the impedance allows for a bigger headroom on my DAP since I listen at very low volumes.

Any love for Tralucent 1+2 IEM (bundled with T1 amp) over FitEat TG334 if my requirements were to find a drastic improvement for Vsonic GR07? Smooth treble, wide and deep staging, sweet mids, and also some bass?

Thanks.

The Tzar 350 is not neutral by a long shot.

I have had the Tzar 350 for about 4 months.  I generally agree with MF that they are not neutral.  Please take my opinion with a grain of salt, unlike MF and many of the other fine members around here, I am fairly new to the hobby and am still learning.  That being said I have really enjoyed my experience with the 350. 

I would say that the 350 are on the brigher side of neutral.  The treble does have a tendency to get harsh, and I am not overly sensitive to treble issues.  I notice this especially with cymbals.  They sound quite tinny/harsh and lack the appropriate timber and resonance to be realistic (neutral) with cymbals.  Granted, this is probably one of the most difficult instruments to accurately portray, but if you listen to a lot of rock or older jazz records then they will likely become fatiguing.  On higher quality recordings I don't notice the sibilance as much and they are the nicest IEMs that I have heard for classical music.  My only real reference for these is the HD800 (which I own) and a number of other headphones which I tested out. 

Besides the cymbal and overly bright treble I like them a lot.  They have a solid natural sounding bass and fairly neutral mids (they may sound a little recessed due to the treble).  I won't get into extension because I don't feel I have enough experience to adequately comment on that.  The 350 has the best soundstage that I have heard for an IEM.  They sound is clearly projected in a 3D manner compared to the other IEMs I have heard (the worst of which tend to sound mono by comparison).  The HD800 they are not, but they are adequate for my portable listening.  I also think they are very strong in imaging and low level resolution.  Sometimes I feel that they image better than the HD800, though this is more likely a limitation of the rest of my gear with the HD800.  The low level resolution is enough to keep me intrigued.  I have no problem hearing details in recordings that I can hear in the HD800.  I also think that they do quite well in portraying accurate tonal qualities of the instruments.  I have played musical instruments all my life and played saxophone in a big band for a short time, so I do have some experience in this regard. 

One last thing, they are immensely improved by using comply foam tips.  They do a good job of cutting out the harshness from the treble.  While they don't improve the tonal qualities of cymbals, they definitely make the 350 more versatile for all types of music.  I listen to them for 5+ hours a day while I am at work. I listen at fairly low levels as well, which also helps avoid fatigue from treble.

I think overall it will depend on the music you listen to and whether you can deal with the treble.  I am not talking about the harshness of the beyer T90s or T1, it only really bothers me on cymbal heavy music.  Are they good value for money?  At $400 I am not sure that they are.  I have a feeling that others may be able to recommend something better for less.  I like them because they are universal, they have replaceable cables (I got tired of my other IEM cables breaking), and like you said the high impedence allows you to have more headroom from your DAP.

I hope this helped
