Thank youHi
That I connected the RU6 to the LP6K was more for fun, for the photo.
I bought the RU6 in mid-December, and was so excited about the concept of being able to listen to my music "mobile", that I bought the Lotoo.
The RU6 is already for sale on EKA.

Using low gain, NOS, I find that 40-55 on the volume is loud enough.That's good to hear! I have a cable I use with LCD-2 currently that terminates to mini-XLR and utilizes short (~6") interconnects to swap termination types.
How's the volume headroom when using with the LCD-XC? I've only tried the RU6 with IEMs so far (Timeless and Nio) and I haven't felt the need to go higher than 45 on low gain.

This DAC/Amp has impressed me so much I think ill upgrade my headcans. But, only after doing a bit of research as to how to match the characteristics of this DAC with over-ear closed-back headcans. Some of the concerns here in this thread have raised at least one question as to how far I can go.
Those concerns are about the limitations Apple has apparently put on the lightning connector regarding how much power it can supply. That is, last night I experienced some cutouts at higher volumes than used the night before. Those settings were gain=low volume=75, and provided a relatively high volume level for my Shure SRH940 over-ear closed-back headcans that are impedance rated at 42ohms. I dropped the volume only to 70 and no more dropouts. My thinking is that I’ve most likely reached the lightning limitation, and that’s my first question(?)
My second question is about using a balanced cable with the new headphones. The RU6 specs state its balanced output wattage almost doubles its SE output. Does this imply better efficiency and less power draw, and a possible answer to the power dependency problem, or does it mean the RU6’s balanced output will exacerbate the problem?
I’ll have other questions about best matching the RU6 to headphones, but first things first…

Did anyone experience EMI noise with the RU6? I'm gonna order mine tomorrow.
And how much better is the Balanced Out on RU6? Wondering If I should get a Balanced Cable for CA Honeydew IEM along with the RU6.

Haven’t experienced EMI while playing musicfrom my iPhone on Wi-Fi. RU6 doesnt not have a balanced architecture so unless you need extra oomph for you IEM you don’t necessarily need it.Did anyone experience EMI noise with the RU6? I'm gonna order mine tomorrow.

It just adds a 2nd amplifier to boost output. In my experience if you are worried about power draw, best stick to the 3.5mm.

I experience EMI when used with my iphone 12 mini quiet often, not as often as with my W2. but it sucks…
I had emi noise only in the change track when ru6 is joined to my phone. Otherwise i had no interference. About balanced in my opinion the difference in terms of sound presentation is small. Of course you have more power but again the difference is smallDid anyone experience EMI noise with the RU6? I'm gonna order mine tomorrow.

I'm not sure you can strictly class the noise we hear at the end of each track as EMI. It's more of a residual noise. If it was EMI you would be able to hear something during the track say if you brought your phone closer to the DAC. What we hear has nothing to do with electo magnetic impluse and doesn't interfere with the track until right at the very end.I had emi noise only in the change track when ru6 is joined to my phone.

so you would hear the emi even if playing music with high volume?I'm not sure you can strictly class the noise we hear at the end of each track as EMI. It's more of a residual noise. If it was EMI you would be able to hear something during the track say if you brought your phone closer to the DAC.

Thanks for explanation. In this case i have no EMI issues lolI'm not sure you can strictly class the noise we hear at the end of each track as EMI. It's more of a residual noise.

The RU6 is not a true balanced output, as there is only one DAC feeding Left and Right. It looks like there is another separate amplifier feeding the right channel at the output to the 4.4mm socket. However I am really enjoying my RU6 4.4mm output to Elegias and LCD-XC.

I seem to prefer the NOS setting on the RU6, however I wonder if Tidal Masters are oversampled when they are processed by Tidal?
Sorry to bring up MQA again.

I imagine I could be wrong in thinking the dropouts was a power problem. Is your M11 your only source of music and power? Or, are you augmenting a smart phone too?"Balanced":

Have you compared both outputs to your Focals?
