Can you tell me what is the Ugreen cable you’re using and how long it is? I’m quite into these dac/amp lately, and will also run it through my ipad, yet a usb-c hub and that long blue thicc cable seems like a cluster setup.

Just measured and its just over 7 inches from end to end.

Ugreen

I used a usb c hub at first and it caused weird problems that disappeared once I got the straight Ugreen cable. May just be related to the usb c hub I was using though.

Hi fellas. I don't recall that this has been discussed already but I connected my iFi Signature to a transparent external DAC (specifically SMSL SH-9 THX) and it was a revelation. It really opened up the iFi Signature sound and the improvements brought about by X-Bass and 3D were more audible. They drove my Empyreans to new places. The Empyreans are great headphones but what's really good about them is that it really showcases the qualities of any DAC/AMP you connect it to and boy did the Signature + THX get showcased.

A couple of days ago I was auditioning the whole pro idsd suite because I wanted to see what an upgraded iFi house sound would be like (compared to my ultimate end goal Chord TT2 but I digress). Thankfully I didn't purchase anything yet because apparently all I needed was an inexpensive THX amp to maximize the Signature's DAC capabilities. Signature is definitely my favorite portable (prefer the house sound over the more analytical Diablo) and it's reaaally good as a portable device but apparently its DAC portion is capable of so much MORE than what its small amp portion allows it to do. On a transparent desktop amp the soundstage increased and the details and imaging significantly improved. Do yourself a favor and try it out because if you like the iFi Signature now, you should listen to the big improvements to its sound.

So X-Bass works when used in DAC mode too? 3D in pre-amp/line-out is the one meant for speakers I believe, no?

TBH I probably I probably attributed the overall improvement to include 3D and XBass because I had them switched as well. Sorry I got too excited to share!

Was just going to question this myself. I sometimes use my Signature as a DAC for a hybrid tube amp and I notice no change when toggling Xbass and 3D. I know the Black Label had a direct or preamp toggle for the analogue output and if you used preamp then Xbass and volume control would work, but I don’t believe the Signature has preamp functionality.

Please help, I’ve accidentally uploaded the pro iDSD firmware (v2.08) onto my ifi micro idsd signature. My laptop identifies it as Pro iDSD and won’t play any music (Via iPhone/laptop)or let me update the firmware.
Is there a way to reset the unit to factory firmware?

Since the internal battery cannot by bypassed, is it safe to run it as desktop solution plugged 90% of the time?
Constant charging may wear battery pretty fast...
This is only thing holding me back, and it looks its the same for the new Diablo.
I think "Desktop" mode which would power the device directly from the AC is what we need.
Maybe that's just me, but this device seems more like an "easily transportable" but still "desktop" device, with possibility to run on the battery as a bonus...

@iFi audio, any comment on desktop mode or battery lifespan?

Hey there,

Our battery lifespan for the Diablo and the Signature is as follows:

turbo = for the most demanding headphones (~6 hours).
normal = for medium-sensitivity headphones (~9 hours).
eco = for high-sensitivity IEMs (~12 hours).

These are just estimates, and it's important to note that some users have gotten longer hours out of each setting - it all depends on your usage with the rest of your system and your headphones.

There is no way to bypass the battery for a "desktop" mode, and it was made to be easily one or the other (portable) depending on your needs as a user.

I hope that helps!

Just switched turbo and Eco around

Whoops!!! Corrected. Thank you for catching that on my end, my dyslexia got to me!

Are there any streaming services that the Signature’s PCM filters won’t work with due to different audio codecs (Apple Music with AAC, etc)? If so, is there a “base” filter that is used by default when played from these sources?

What do you mean....?

The device is always fed PCM or DSD, that's it.

Thanks for the answer, but what I mean by battery life is how fast will battery wear down when a device will be connected to the AC almost all of the time.
Some kind of battery protection could be implemented, like keep charge it to 80% and let it discharge to 20% and again charge it to 80%.
I think it would prolong the life of the battery, keeping it at 100% and charge it continuosly while it is using is quite bad for lithium batteries AFAIK.
