Your comparison between the Rx MK3 and SR71b is interesting, but I disagree that the SR71b (in balanced mode and with low gain) has sufficiently comfortable low volumes that were also channel balanced, at least with sensitive headphones like customs and the Edition 8, and with a hot source like the CLAS or HM-801.  With custom IEMs, there was literally one tiny notch on the dial that I could get which wasn't too loud for me and was channel balanced, and with the Edition 8 there was just slightly more room to manoeuvre on the knob.  

That said, on the stock MK3, there wasn't any comfortable setting on the knob with customs, and one tiny notch for the Edition 8.  I'm getting my MK3's gain lowered, I'm really looking forward to getting it back and seeing how much more range on the knob I'll have.  Also really want to see if the hiss can be lowered.  

In spite of these issues, while I enjoyed the SR71b, I felt like the MK3 was a definite upgrade for me.

Hi there. I think this is where differences in individuals hearing come in to play. My ears are 48 very hard years old and I think they are simply not as sensitive as yours which is probably why I have to have the volume turned up more and don't experience the imbalance issues that you have. Also I think what I am listening with is not as sensitive as your equipment. I can totally understand where your coming from in balanced mode, it does require quite a bit less volume than single ended mode in my experience. I wonder what amp would be able to do what the blackbird and ALO do but with a much lower noise floor and lower gain for the more sensitive IEM's?

As to the bit rates, There really is no difference of note between the lossless files in my experience but I find enough with lesser rates not to use them. If I was pushed and if it was a good day and nice and quite and on very few recordings I would say there is a tiny bit more air and space to the music between ALAC and AIFF but it is so small and fleeting that it really does not matter. I guess its just that my rig as it is now just digs so much information out that hard drive space being so cheap and I had time on my hands then why not re rip it all totally uncompressed, who knows what the CLAS will be like if they end up making a balanced version, then maybe the difference would be greater. But most certainly there is a difference in emotion, texture and dynamics between 320k and lossless/AIFF even to these tired old ears to warrant having uncompressed files.

I am glad you have found the RX an upgrade, I think as I said at the end of my last post. Between all four we can all have our own personal audio nirvana. For me it is not about better or worse, just different but all good different!

Thanks for the info!

any inputs against the mk3 vs the national? I have both but the national is still in the burning-in phase. I know that I should hear it for myself to judge, but I would just like to know people's input on this matter.

I'm not sure if it's been asked but can the amp be used while charging?

Yes it can.

I've asked Caleb at ALO about this and he said that there is no problem using the amp and charging it at the same time. The only thing to think about is that if you have the charger plugged in and using it at the same time, say as a desktop amp, you should sometimes discharge the battery completely or the battery might loose some of its capacity.

 

Just something to keep in mind.

 

Happy listening!

Help! Is it ok and possible to charge the RxMK3 using the Algorhythm Solo's charger? Apparently, my Mk3's charger suddenly short circuited and is not working anymore. Please help me out!

No they are different voltages. Each has its own specific charger.

even if the CLAS charger is at lower voltage it won't charge the mk3? because with an iPad using a lower voltage iPhone charger, it does charge but takes longer. So I was thinking that maybe this also works for the MK3 using the lower voltage CLAS charger :(

There a lot of pages devoted to these devices. Somewhere in there was a discussion about these power supplies and the fact that you cannot use them on the other device. Each must use its own specific power supply. Sorry...

Better than damaging a great piece of gear by accident!

reading this forum, many people have said that this amp may not be so good for iems due to hiss when listening at low volumes even when some people got theirs amps noise floor lowered. Is there another portable amp that is just as good as this one but are better suited for iems like the togo 334?

I guess the ALO audio National would be your best bet for that. But I think the RxMK3 will have not much the same problem with the To Go 334. I had the Sony XBA-3 and there was no hiss or imbalance problem
