Functionality and Balanced aside, How does iDSD Signature compare to the Gryphon? Obviously, because of the higher power it will drive bigger headphones with authority but, what about the sound with easy to drive headphones & IEM's?
Could you please take some time and compare these 2 devices with IEM's and share your impressions?
If the Signature is still the better sounding device, then I'll keep it and get the Cayin RU6 for portable needs.
I've waited too long to make a decision and would like to make one and order a more portable DAC than the Signature by next week. So far, I've narrowed my decision down to Gryphon, RU6 & XD-05 BAL. If someone has heard the BAL and can compare it with other iFi devices, that would be great.
Sure. If you still have the chance to return the micro iDSD Signature, I prefer the Gryphon in every aspect, and here’s why.
The micro iDSD aims to straddle the lines between the desktop amp and the portable. It has dual Burr Brown chips and a bit more powerful amp compared to the Gryphon. But like all the micro iDSD iterations, I think it fails to satisfy either niche. It’s too bulky, heavy and clunky with cables to be an ergonomic portable, especially if you’re using it with an iPhone and all the CCK requirements involved to hook it up. It’s a mess of wires and isn’t really practical to use with a phone—it wants to sit still in a hardwired configuration.
And as an authoritative desktop unit it cuts corners with the faux-balanced circuitry and battery-dependent operation, and honestly I never got used to any of the PowerMatch and ieMatch tweaks—I felt overwhelmed with options and got lost in trying to decide which constellation of settings got me the best S/N ratio. It was a pain. And I definitely didn’t enjoy the accidental switch between modes that blew my ears out. Finally, I have always had issues with the channel imbalance problem that occurs at low volumes with the micro iDSD line—iFi offered explanations for why this occurs but the bottom line is that it isn’t an issue with other amp/DACs and they failed to solve it through a string of upgrades.
The Gryphon on the other hand is perfect as a portable but functions perfectly well in a desktop configuration. It has plenty (more than enough!) clean power for any IEM and for all but the most hungry over the ear headphones (such as a Hifiman Susvara). It’s exceptional measurements belie any need for dual DAC chips, and there are distinct advantages to a full balanced connection—my Focal Utopias and Sony Z1Rs sound powerful and authoritative connected to the Gryphon’s balanced pentaconn jack, and they sound nice and quiet through the 3.5mm S-balanced jack as well. And this time they simplified the ieMatch option very successfully—there’s a setting for 4.4mm balanced connections and one for 3.5mm S-balanced single-ended, with “off” in between. No guesswork involved and it works great.
The circuitry on the Gryphon is quite brilliant. There are separate USB C jacks on the rear for charging and data that isolate the two to keep noise contamination at zero—and they function simultaneously. There are not only 3.5mm and 4.4mm headphone jacks on the front, but an ADDITIONAL set of 3.5mm and 4.4mm jacks on the rear that can act as both line outs OR line ins depending on whether you have a USB signal connected to the rear. If you have the unit in Bluetooth or S/PDIF mode for a signal input then the jacks act as line-ins; if you have the unit in USB mode connected to a phone, PC or streamer, then the rear S-E or balanced jacks act as analog line outs to run to a separate amp.
This is how it can perform brilliantly as a desktop option—you can connect a PC, phone or streamer to the USB port for your signal, then run the 3.5 or 4.4mm line out to a desktop amp (ifi’s own Zen Can and Pro iCAN Signature handily have a pentaconn input to facilitate this nicely), and use the unit as a top notch DAC with the benefits of the analog xBass II and X-Space options passed through to the amp—that’s a first as far as I know. The line out only functions in variable volume mode but at full volume the S/N ratio is equal to line so it doesn’t matter.
And, you can have the unit connected to the separate USB power at all times to negate battery woes—it still runs off the clean DC power at all times, but keeps its charge via the AC hookup. Another first in this category and price point.
The graphical interface on the Gryphon is also very well-done. You can switch between inputs, xBass and XSpace settings, see the signal sampling rate right in the window, MQA, etc. And the analog volume knob is also extremely satisfying; it has a wide range to avoid accidental jumps and its color tells you where you are in terms of gain. This is an enormous win for iFi compared to the original xDSD’s too-complicated volume potentiometer, which tried to do too many things and got confusing.
I also love the bimodal analog tone control they added with the xBass for added punch and the new “presence” option to push up the high mids subtly, and you can have either one or both active by a switch on the back. And it comes with a full complement of high-quality OTG cables for every imaginable phone or PC—no more Apple CCK kit necessary. It has a lightning to USB cable included that connects the two with no fuss, and a similar cable for Android along with a longer USB C cable for charging.
In terms of sound quality, the Gryphon sounds amazing—certainly no less immaculate than the micro iDSD and with far more versatility. The noise floor is zero—it’s deathly quiet even at full volumes, and the resolution and soundstage are as fine as iFi gets before you jump to their Pro iDSD/iCAN line.
And they solved the channel imbalance at low volumes!
Finally, if I had to choose between the two I’d go for the Gryphon—and I did. I can’t imagine you not being satisfied with it; it truly does it all and I think it’s the most innovative and feature-rich offering iFi has released to date. It’s built with military-grade precision and confidence yet feels weightless and effortless during use. They knocked it out of the park this time and I love the thing.
Hope that helps…
