it really is unforgivable that they didn’t include Bluetooth.


Aye a slack release by iFi I reckon a BL with a 4.4mm…new stuff buy iFi in the new year I reckon :+1:

Anyone have this new release that can fill us in on SQ and overall performance? Especially when compared with black label which can be grabbed new for about 200 less?

I’m looking for a portable Dac/amp I can use to power my 990 600ohm, as well as future proof to planars or anything other that is crazy thirsty to drive.

Is the sound signature typical ifi? Warmer, full bodied sound at expense of soundstage and separation, or is this Dac/amp a whole other animal?

I just got the Signature and have had the BL for a while now. For the most part I can agree with Zeo’s review.

Breaking down the differences the things I noticed right away were the following:

  • better instrument separation
  • large wider sound stage
  • better control over mid-range
  • less congested sounding over the BL with certain tracks
  • better control over the bass
  • improved control with xBass (doesn’t sound as bloomy with some headphones)

I would say it’s definitely worth it over the BL if you’re buying new.


Wait, what? BL is still like $500 if you can find it new and 300+ used.

EDIT: Am dumb. You mean the the nano iDSD, not the micro

Since apparently you can use the xduoo XD-05 Bt reciever as just a BT in optical out, I ordered one to give it a try with my BL. I’ll make a thread for it in DIY once it arrives next week

I just cant wait for it to be $500 used in like 6 months. Thats when ima probably jump (assuming the xduoo balanced doesnt somehow blow it away or the red micro come out and be better in basicaly every way)

not really looking at or wanting a work around. someone just needs to slap iFi for being so stupid!

I mean, yes, they absolutely do, but a work around may actually make it a more viable device (at least for my use case it certainly will)

Did you end up making a thread for it? Interested in ways of making it bluetooth. Another option would be the topping bc3.

Just too bad they did not incorporate. But I need something portable for more power. Have some planars laying around. Sundara and gl2k that can use more power than my current fiio q5s provides. I’m quite unimpressed by these headphones on my q5s.

Could also be I’m just no fan of these type planars…

The BC3 may be a better shout. I got the xduoo one (only one at tge time) and the ldac support is just horendus. Jitter so bad you think it’s intentional. Litteraky can’t hear the music over it. You have to turn ldac on and off a dozen times for it to finally catch. Right now I’m just using a pi with a battery pack yo stream roon too.

The Bass in God is a Woman (Ariana Grande), Dancing With a Stranger (Sam Smith) and Magic (Kylie Minogue) …are… SUBLIME with the Black Limba’s and the iFi iDSD Signature on normal gain @ 1 o’clock on the volume dial! This is how POP music should sound. MAGIC. :yum Loud in yer face and thumping.

That’s where type 1 or 2 woods truly rock! Type 4 Wild Chechen can’t compete with the kick, power and warmth of the Type 1 Black Limba where you just wanna feel da bass… and that’s without flicking the xBass or 3D switch on the Amp. Type 4 with the xBass come close to the Type 1 but still lacking a little warmth. They are still great though for rock or more complex music, or Jazz where you need a little more articulation in the bass.

Love the sound of the Signature which has now certainly replaced my RME ADI-2 DAC for ALL duties!!

Great companion for the iPad mini with the short camera kit cable - anywhere around the house or the train, plane, bus and automobile! (or just while goofing off on the interwebs!)

Did you get to try out the Diablo too? Or have you only tried (and clearly are loving) the Sig? I’d like an upgrade to my Zen stack sometime soon and am debating between both.

I listened to Diablo and it was a bit more aiming for neutral and pure and I was looking for something more musical as I already have an RME ADI-2 DAC for that neutral clean purist sound and the TH610 even with Lawton chambers could still do with a bit of warming up, which the Signature does perfectly!
