It feels like the Avalon has settled now as I haven't heard any major changes to the sound signature of late.

While using the black/black filter arrangement, the main changes I observed was the steady increase in the depth and strength of the bass. It got to the point of overflowing into the mid frequency and as a result the vocals and instruments started to lose some sharpness and clarity.

I thought it was time to start playing around with the filters then. I used bass filters ranging from red to black and upper filters from purple to black.
I'm now finally settled with blue/blue. Blue bass filter tames down the bass, but doesn't take away the nice sub bass and detail. The high frequency blue filter gives me nice clarity and reduces the brightness somewhat. Mids sound clear and concise while still retains nice sparkle at the upper regions.

My favourite tips are still currently the Final E-Type (purple) sm . Next favourite is the IMR tip sm. Both tips are comfortable and I can wear them for prolonged periods. IMR bore size is slightly wider in diameter and I will get a little more brightness in the sound with these.

Comparing the Avalons to the Semper, they both produce great detail. Vocals in the Avalon are set much more forward. Semper vocals are set back more and I find that vocals blend in with instruments in the background more. For this reason Avalon has a sound stage with more depth. I feel that there is more distinction and discreteness between instruments and vocals overall with the Avalons. I think sound stage width is similar. If I go for a wider bore in the Avalons the soundstage width increases a little, but it's not "starfield". Perhaps more burn in? Unless starfield is referring to layered depth?

The difference between the Elan to the Avalon and Semper is in the high end detail. The detail in the Elan is there, but I need to keep the volume output relatively higher. For me, at good volume the Elan sounds rich and dynamic. At lower volumes, higher end frequencies start to lose their detail and liveliness.

The low end volume output is where I find the Avalon and Semper work beautifully. In a nice quiet room with little ambient noise interference, I can up the volume on the player by only a wee bit and I still get wonderful detail through the range and still get an adequate warm linger of the lower end bass and sub-bass to accompany.

Avalon is brighter than the Semper. For me, I hear it as an uplifting brightness and it suits me fine. I don't hear sibilance. Elan is perhaps somewhere in between these two.
The soundstage of Semper is more recessed and more like what I'm used to. I think especially nice for instrumentals and electronic.
The forward vocals on the Avalon is growing on me as it does give me a more layered depth to sound stage.

So blue filter takes the highs more than the stock filter

There isn't much between the black and blue for me, but I can't help thinking that there is a little veiling with the black high filters. To experiment later I might try taking the foam out of the black filters later.

Is there any other way to solve driver flex?
Any of the following may help:
  1. Using foam tips,
  2. Using one size smaller tips,
  3. Inserting the IEM slowly to allow air to move out form your ear canal,
  4. Opening your mouth and pulling your earlobe up with the opposite hand to widen your ear canal while inserting the IEM, then slowly lowering your ear and closing your mouth.

Looking for an upgrade to my Fiio FD3, which is a DLC single dynamic. Would anyone be able to list the differences between the OZAR and the SOG? My preferences are detailed/extended treble, fast clean deep bass. Currently the Serial meets my needs for bass, but not as treble forward as my FD3.

Moved on to Whizzer SS20 L tips and shallow inserted them. This solved the driver flex on my IMR SOG. Is there any other way to solve driver flex? Full seal always results in driver flex on my SOG.
You can sewing thread and get it through the tip opening, attach tip, cut extra. Also can get it through the tip canopies with needle. The thicker the thread, - the more venting you'll get:smile_phones:.

No problem with the 2 pin fit with the iem? i find with IMR iems, it can be hit and miss.
No problem with the IMR SOG
