Ifi has some intresting products which solve unique problems and this device is essentially the combination of all those products into a single portable(Not Pocketable) unit.
-The power output is amazing for almost any kind of headphone
-There is no hiss in extremely sensitive iems when using iem match
-Xbass is amazing
-really good battery life
-as a dac its pretty sterile and open, if sterile sound is not your thing then it can be "fixed" with xbass
-really good to use with planar magnetic headphones which have low impedance and low sensitivity
I don't think there is any other comparable product in this range which can work as a high quality dac & amp
So glad to know that you love them:) We look forward to serving you again.
idsd Signature has a great dac which I wasn’t expecting as I brought this for its desktop like amping strength. It gives a sense of effortless play specially guitar strings are buttery smooth.
On contrary some tunes have peaky treble, I think need to see the power and sensitivity switch combinations with eq settings.
Overall very good ‘not so portable’ dacamp which can beat atleast half of bulky desktop amps coming around its price range.
Let me just quickly throw a disclaimer here before I begin —‘I am not an Audiophile or an expert on sound’—therefore consider this review layman at best.
I got IDSD Signature as an upgrade to my ageing yet faithful—Fiio Q5. Although Q5 pairs exceptionally well with my Hifiman Sundara; I have been wanting to upgrade to a more solid and ‘does it all’ kinda DAC/AMP that would not chicken out when pitched against big boys like hifiman Arya if opportunity calls for it. I also based my decision on portability. You may rightfully call IDSD Signature as ‘transportable’ ; but anything that I can fit in my palms and gets me going without a mess of too many wires is portable at best.
I had wished if these were black just like their predecessor but upon unboxing they came off quite handsome in person. They have a faint blue metallic sheen to them and I think I can happily live with blue especially after considering what they did to my Sundara.
Sound wise, IDSD Signature offered me a very welcome change. I find Signature to be neutral with a slight touch of mid bass in lower mids and it’s apparent the moment you switch it on. I have to say I am loving that tiny smidge of bass in lower mids. The general airy-ness, clarity and separation coupled with an occasional flirting with XBass switch make this blue-brick a real DOPE MACHINE !!!
Take it from someone who hates bass boost implementations. But on IDSD Signature, I only had to flick the XBass+ switch just over a few times for me to like it. XBass+ does the bass just right for me on most tracks if not all. It’s a sweet switch to enable fun sound if you are not in a mood for serious listening. For most part however, I keep it off and I am happy that it’s there.
I wasn’t adequately impressed with 3D+ switch. It only makes some sense to me when I enable it on a recording that has Minimalistic arrangement of instruments and vocals like jazz. My bias for uncoloured sound makes me want to reject it almost immediately. I am sure people who are more open and unbiased than me will definitely find 3D+ fun to engage.
I found IDSD Signature to be very solid in terms of sound, built and use case. I love how they impart their musical spirit with my Sundara without being overbearing. My only gripe with IDSD Signature is the volume dial. It’s very sensitive and allows for a very fine dialling ‘which is great’—however I wish it offered a little more resistance while it was at it. Other than that it’s a very fine unit.
We are glad you had a comfortable shopping experience with us & it is delightful to read such positive reviews on your product! Cheers & Welcome to the club!
I had bought few DAPs before adding iDSD Signature to my collection, but none are as versatile as this portable DACAMP. You need power? This has loads of it. Which is quite an achievement for the product of this size. You need one device that will gel well with both your IEMs and Headphones? This is it. It sounds fantastic with rich and full bodied sound, has excellent details, wide soundstage with very good extensions in low and upper frequencies. I had used quite a few IEMs like JVC HA-FDX1, Sony IER-Z1R, Sony IER-M9, UM Mest MKII, Audeze LCD-i4 and headphones like Focal Clear, Sennheiser HD560s, HiFiMan Ananda with it, and all of them had great synergy with the Signature so much so that I prefer Signature to my DAPs(HiBY RS6, Shanling M8) for my Focal Clear & Sennheiser HD560s. Not that it's better than the said DAPs, but Clear sounds best with the Signature. DAC implementation is excellent, and for me this DACAMP performs at par or even better than most desktop DACAMPs in this price range.
And not to forget the XBass feature in it. This is a great feature to have for any basshead or for any guy who wants high quality thumping bass. Focal Clear, which already has good bass performance, gets even more bass thump when XBass is turned on! It's also very useful with headphones such as HD560s or even Arya(yes, this does have very good synergy with iDSD Signature too).
And coming to cons, this isn't exactly portable but it's kind of transportable. There's channel imbalance at lower volumes, which is an accepted thing by iFi. But it's perfect after volume reaches 9'o clock position. And lastly there's lack of proper battery level indication, while on charging or while using. All these are nitpicking when its performance is topnotch.
A highly recommended portable DACAMP for IEMs and Headphones alike.
We are so happy you took out time & elaborately reviewed the product. We are sure this will help our customers to make an even better & informed decision.
It has ample power as well as analog sound settings to personalize sound. I highly recommend it. I pair with an extremely source picky headphone in the HD800S, and with Xbass and 3D+ turned on with a minimal treble peak dip EQ on my laptop, the headphones sound incredible.
We thank you for this lovely review & we are glad you are enjoying it! Keep the music playing.
