Do you think that iRiver/AK might have changed or tweaked the software digital filters in-between firmware versions? I grabbed an RWAK120-B last fall (2014) that had 1.40 pre-loaded on it, and it provided a very "liquidy" sound that, while hyper-detailed and nuanced, sounded slightly...

I've had this same issue when trying to setup my AK120 as a "USB DAC" as well, since it seems as if the AK120 lacks a true/dedicated USB DAC audio output device capability, even though it is marketed as having "USB DAC" functionality (only up to 24/96, though, since iriver has never released a...

I agree with this... when combined with the Sennheiser HD650s (balanced), I find the ALO Rx Mk3-B+ to sound a little distant, with mediocre soundstaging and imaging, being overall a generally boring sound-signature (with or without the bass-gain knob turned on.) However, when listening to the...

I didn't have to install any drivers. It works great as a USB DAC in the latest OSX Yosemite. Streams native DSD via DoP in Audirvana+ over the USB. Selectable up to 24bit/384kHz in Audio MIDI Setup. I do have it connected via a Schiit Wyrd USB Decrapifier, though... but I'm assuming it should...

Try to unplug the USB cable and hold down the power button for 5+ seconds. If it still doesn't turn on, plug the USB cable back in and hold down the power button to try and turn it on. I had a similar issue as well, unplugging the USB cable from the charger and holding down the power button...

Just received the Calyx M in the mail earlier today from Poimandres for an amazing price... the device is in excellent condition, practically like new. Been enjoying it ever since I took it out of the box, especially the USB DAC ability of the Calyx M on my Macbook Air. The internal XMOS USB...

Any idea when the ALO Rx will be restocked (and black color options available)? Hope I'd be able to pick one up soon.

Fairly interested in this player to use mostly at my desk as a secondary USB DAC (connected to my MacBook AIr), and a DAP as well with my IE800 and K3003is. Does anyone know how the USB DAC section/ability holds up in comparison to its DAP ability? I'm assuming that with the latest firmware...

I've just had to send back my IE800 recently as well, due to the right driver dying. I also had issues with stiffness of the left earpiece cable, but didn't want to wait for the RMA/repair shipment just to fix a stiff cable. However, after the right driver stopped working, I pretty much had to...

How does the SR-71B pair with the K3003i?   I've been looking for a slightly smaller amp to pair with my RWAK120-B that has a balanced Kobiconn line-in, and the RSA SR-71B seems to fit seemingly well with the RWAK120-B form factor judging from the pictures I've seen posted of them stacked...

The K3003/K3003i is a nice compliment IEM to the IE800. While the IE800 sounds more organic with a full, lush sound that doesn't lack in any aspect from the lows to the highs, the K3003/K3003i has very crystal-clear/detailed mids and highs (i.e., slightly bright) with probably the largest...

The free-market vs. state-economy (or command-economy), lol. Oh well, what can you expect from those that embrace the free-market except the desire to make money/earn profits and planned obsolescence, lol.   I'm still hoping AK will release a new firmware for the AK120, maybe addressing the...

I believe the K3003 sounds better than the IE800, although the K3003 can be a bit too harsh sounding/bright at times, along with the bass dynamic driver sometimes sounding audibly slow in decay compared to the mids/highs. The IE800 can sound more warm and "organic" in that regard (vs. the...

  What kind of interference do you suspect it to be?   I have had cellular network interference with the Theorem 720 on my iPhone 3GS and iPhone 4S on AT&T (AT&T uses lower >1000mhz spectrum frequency, if I recall correctly), but once I switched over to T-Mobile on my iPhone 4S (1800-2000mhz...

Hello,   I currently have the Cypher Labs Duet amp and have been enjoying the sound overall, it's very detailed with a great mid-range, and doesn't hiss at all/has a perfectly black background with IEMs. Compared to the ALO Rx Mk3-B+ amp, the Duet sounds a lot cleaner, and in some cases more...
