ExplodingAmoeba Cancel that! You want an iFi GoBlu! Actually, on second thought, what you really want if you can make it happen in any way, shape, or form, because it may be the last DAC/amp you will ever need to buy (it will do everything you ever need...) get the iFi Gryphon! They both support LDAC which streams up to 990kbps. AptX only goes up to 384kbps (Classic) 420kbps (Adaptive) or 576kbps (AptX HD). I'm guessing that it probably isn't AptX HD, that's normally only in high-end products like my $1100 Kanto TUK speakers, all other Bluetooth speakers that Kanto makes for all models less expensive than their flagship TUK's only support AptX Adaptive and Classic...
AptX HD isn't that bad at all... It at least supports 24 bit playback, but still max 44.1 or 48khz sampling rate. LDAC is what you want for your streaming needs! Even on "Best Effort" which is the default, it will dynamically go between 990kbps (Best Quality), 660kbps and (worst case, of you are far away) 330kbps. I always go into my developer options, or on Windows before I started rockin' Ubuntu I used something called the Alternative A2DP Driver, and on both computer and phone forced it to always stay at 990kbps! At that bitrate, it is as close to lossless as you'll get!
On 330kbps, AptX wins, but on 660kbps and 990kbps, LDAC cleans the floor! The unique thing with the GoBlu, and the Gryphon is the great LDAC support. If you run Windows, search up the Alternate A2DP Driver, to get LDAC on Windows, and then you are golden for both phone and computer as well! (Linux does LDAC natively)
On my nice TUK speakers, I use my iFi xDSD Gryphon as a desktop DAC/amp when at home, it's DAC is better than the one in the TUK's, so I use the dedicated 2V line out from the Gryphon to wire into the speakers, and that way I also get LDAC 990kbps transmission! It's the best device if you can handle the upfront cost. I have thought to myself 1000 times at least over the year I've had it (every time I've pulled it out and many times while using it, every day!) that is is one of the best purchases I have ever made! It does absolutely everything, and slips into any pocket to go out with you!
Otherwise, the GoBlu also has the same BurrBrown DAC chip as is in the Gryphon, just I think it runs 1 vs 2 or 4 in the Gryphon. Don't know for sure, but I think it's half the chips, and less power in the amplification stage. Very good high quality DAC chips. But it can be used as a Bluetooth receiver, with LDAC, and also as a standard DAC.
The Gryphon played nice with my Campfire Andromeda's, which are notoriously sensitive headphones. To eliminate the (slight) background hiss, I used their IEMatch feature. Then I user the built-in XBass to boost the bass back up to neutral! Both the Gryphon and GoBlu have XBass and XSpace (soundstage widener), both implemented completely in the analog domain, not digital!
Gryphon can be used as a desktop DAC/amp as well, and it also powers my Dan Clark Audio Aeon 2's. These are notoriously hard to drive, with very low impedance and low sensitivity both... (13 ohms and 92Db) Yet the Gryphon has power enough for them, it will also drive most things you will ever throw at them! It takes optical S/PDIF input or output, does line input or line output. Can be used as amplifier only, or DAC only. It's my audio Swiss Army knife!
GoBlu is more of a good standalone DAC/amp, and a great Bluetooth receiver/DAC/amp. It has less power but will still drive a lot!
