Hi regarding insertion depth I personally find that you don't need to push them in at all, well barely. I use the over ear clips that came with the i20 and once you get a comfortable fit the tips pretty much give a good seal with little insertion at all. By the way I use the large silicone tips which for me offer a great seal.
So when I first got my iSine, I had the same feeling about the treble being spectacular but wasn't enthralled with the balance or mid/bass yet. The original non-groovy tips just did not work for me no matter the depth. They'd move around and were just not quite right. Then I found that I apparently love the way they sound with Comply tips. I'm pretty excited to get them back from RMA tomorrow and give the Groovy tips a go. Will report back on if I stick with Comply or move back to stock (groovy) tips. I generally prefer shallower insertion with Comply 600 Comfort tips.
As for the DAP question, the Cipher is probably made with slightly cheaper parts but also vertically integrated if you will, like an Apple design. It's simple to use, which is neat. The DAP should be able to get there as long as you have robust EQ control.
Thanks for the feedbacks!
I have further played around with the iSine 20 and I think it is a keeper
Interestingly, it took some parts that I don't use anymore to come up with a pretty nice combo ...
1) For DAP, I found the combination of Sony A15 and HeadAmp Pico gives a really nice source for the iSine. Cipher seems to be very U-shaped and whilst the EQ on the A15 is nothing to shout about, it has enough (esp. ClearBass for the low end) to give the iSine a very similar sound to the Cipher. As for the amp, Pico is known for its clean and precise soundstaging and this serves to give the iSine more control and precision over the Cipher. This combo also solve the "ringing" I get when listening to classic piano sonata. The whole presentation is also brought forward and more immersive, and in this regard, loses a bit on the layering when compared to the Cipher.
2) For cable, I have a spare Toxic SW with overmold (and rather lucky that it is overmold). Being overmold, I can easily cut notches to the connectors and I did it in such a way that I can connect the right connector to the left earpiece and left connector to the right earpiece... Why? So that I can wear the iSine as an over-the-ear
Much more in line with what I am used to... Also, I noted that with overmold, the pins are normally thinner as compared to pins from UE or Edolic connectors. With thinner pins, it will not enlarge your pin connector on the earpiece, else if enlarged, the original cable and the Cipher cable will be too loose to fit!
3) For ear plug, a pair of Muse double flange, fit nice and deep. Good seal, enough to cause a "click" sound when inserting on one of the earpiece (
sounds like driver flex, which is interesting. considering these are planars and opened-back... is this normal?).
