I listened to this combination yesterday down at the waterfront. Used my Android streaming Amazon HD as a source. I've come to the conclusion that this is likely the equal of my home stereo setup that cost roughly 15K or so. Love this amp!
I think it could be even better if I upgraded the cable between the dac and amp. Right now using an Amazon special that cost about 25 bucks. Anyone recommend a reasonably priced upgrade cable?
Any idea about what should be theoretically the best line in voltage input in balanced mode ? I can choose with the A&K Kann Alpha balanced line out set to 1.6V, 2V, 2.5V or 4V ?
I don't ear any background hiss at any input voltage and high or low gain mode.
I would say from 2V, it sounds powerful enough to move a DCA Stealth with the BX2+ (High Gain).. but difficult to say if at 4V as line in with BX2+ in low gain mode, there should be some improvement with Class A mode.... or even if I should have a better battery life.

I'm far from the expert but as I understand it 4V is basically the standard for balanced connections. If you can run that way and then keep the amp on low gain to increase battery life it seems like a win-win. Battery life is the only disappointment I have with the Romi but I'm willing to accept it for the great sound. The way I listen the battery actually lasts long enough but that's probably not the case for everybody

I think some other amps recommend 2.1V even for balanced input.
As I couldn't find any info specific to the Less Bx2+, I was wondering if SQ could be affected by using 4V and low gain.
I don't know with the Bx2+ but for other amps in low gain, less amp's modules are activated so instant juice can be really restricted too when needed.
I am using it at 4V low, I didn't find any real improvement for battery life (I just know that I get 3 hours or even less in 2V input and high gain).

These are my observations of high gain versus low gain using the Dunu Zen with the BX-2 plus. I do find the high gain to sound more energetic but there is an audible hiss. It only seems noticeable when nothing is playing. I've been using low gain because of this, but I think I'm going to give high gain another chance based on what I have read here
I seem to remember a photo that showed one opened up and it looked like a standard battery that was just a simple unplug. I'm not 100% positive however. I would send an email to Romi. They've always been good about getting back to me whenever I had a question. Eventually we'll probably all have to figure out how this works. Although my Chord Mojo is several years old and the battery still seems as good as new. Just thought of something, did this happen all at once or gradually? If all at once maybe the battery isn't bad, maybe some kind of a connection has failed inside. When plugged in to charge, what is happening with the green and red lights on the side? Have you tried a different charger and cable? I've seen several chargers and cables go bad. Good luck, let us know what you find out
The battery is glued to the case and connected to the pcb with a connector, no soldering needed. You just need a new battery and to be careful when ungluing the current one.

I’ve acquired it recently and despite it having seen low usage by a couple of previous owners, I think it’s been sat idle for long periods at a time. I’m not convinced that isn’t perhaps an issue with the charging indicator being wrong. As it currently stands, I can run it connected to power, with all bar one LED lit. If I remove the power, the blue LED around the volume wheel goes off and the sound it puts out sounds like you’d expect it to if it were on its last ounce of juice! I’ll try do some full charge/discharges to see if I can coax a bit of health into the batteries.
why such awful color ???
I wouldn't go out and use it in trains or planes with this bling bling color.
Now, I really hope the Fiio M17 will be sufficient to power my low sensitivity headphones on the way (DCA Stealth)
