How would you say the Gryphon compares to the DAP with the IE 900? I'm very curious about how it sounds, now that I've heard the Go Blu.
That is a very tricky question/comparison. I don't own the Go Blu so I can't compare with that particular device I'm afraid.
The N6ii is also fairly unique in that it offers several different DAC modules as you probably already know. All the DAC modules are subtly different. I'm using the N6ii + A02 with the Gryphon at the moment, its the best I've heard from that card, the amplifier in the Gryphon is very good and I like the XBass+/II feature too.
N6ii with the R01 probably has the best synergy with the IE 900 so I think it beats the N6ii + A02 + Gryphon but the Gryphon has enough power to drive more power hungry headphones, on paper it has twice the power output over its 4.4mm output compared to the R01, so there is that.
Gryphon beats the original xDSD too, if only for flexibility, but probably slightly on overall sound balance/quality too.
Personally I usually find very little differences between various sources anyway so you can see my dilemma here, for me I had to get the xDSD Gryphon because it was exactly the device I'd been looking for because its so versatile, it basically had everything I was looking for in a portable DAC/amp.
Apart from the habit it has of catching me out with moments of full blast output (two so far and not nice with a device that is capable of 1W output), over USB the source I can't fault it. The problem is source volume controls the master volume, that is not what I'm used to with the original xDSD.
The Gryphon is probably perfect for me and I think we will have a long and happy relationship.
Help
I’ve just purchased IE900. I really like them and don’t want to listen IE800s after them.
However there is a problem with fit. Usually I always use Medium stock tips.
With IE900 I have good isolation only with Large foam tip.
Please recommend alternative tips which may help me resolve fit problems.
In manual it’s written that foam tips are usable for 3 month.
I can only advise what worked for me, at first I used the Comply SmartCore Audio Pro tips that only come in Med and Large Sizes, fit was good with medium but I knew the life of these tips would be measurable in weeks so I persevered with the included tips. I couldn't get a seal at first with any of them even the large size, then I tried the medium size on the outer position for a slightly deeper insertion, now fit is perfect.
The outer position is a little trick the included tips have that allow them to detent/lock in place further out from the IEM body, try it with all the included silicone tips you may get a good fit too.
