Does anyone if when the UHA 6S Mkii is plugged into USB, but charging is off, does it run off of USB or off of battery? Thanks!

I'll try to remember to check tonight and post here, but I am fairly certain it runs off battery.

Looks like it runs off the battery, but you can still use it as a DAC and charge at the same time, if you want.

Great! Thanks for checking!

Has anyone tried the Burson Audio V5i opamp with the UHA-6S.MKII? Does it fit and how does it compare to other opamps?

 

[Noor Al-Tamimi]

I've owned the UHA-6S.MKII for a few years now which I upgraded to from a FiiO unit and I have to say the the difference it makes in audio quality is astonishing.

It was definitely a big investment but one that has really been worth it.

I'm curious if there's anything worth upgrading to from the MKII or whether there wouldn't be any noticeable improvement?

For reference I am currently using the Sennheiser IE800 IEM.

Are ya'll liking this amp for IEMs? Thinking about going with the AD8620, which I liked in the JDS Labs C421 years ago for it's soundstage depth and end to end frequency extension.

Hey Noor,
Which opamps do you have in it? Another thing you could do for fun is to try some other opamps for a slightly different flavor. Not sure if these are the best for IE800, but I run AD 4627-BRZ opamps in mine and have kept it because it is just a solid IEM amp.

Yes, 8620's and I still use them today. I've had quite a few small headphone amps and they always seem to end up with a pair of 8610s or an 8620. I even had the older iBasso balanced amp and dac, 8620s ended up in there too.

 

[Jmop]

Is the amp section only still on the warmer side with the 8620 or is the consensus that it's closer to neutral?

 

[Jmop]

Bump again for 8620 info!

 

[Bazirker]

It's been a long time since I had this amp, but I recall it being fairly neutral.

Quick question about the UH6SMKii and an iphone. Should i turn the power on the Leck first and then plug into the iphone (via usb + lightning to camera kit)? Or should i connect them and then turn on the power to the Leck? I felt like the iphone used more power battery life with the Leck than with the lightning-3.5mm dac. Since the Leck was doing the DAC work, i expected the battery to last longer...

Not much traffic here recently. Ha. Got a used Leck UHA6S-MKii if anyone is looking: https://www.head-fi.org/classifieds/leckerton-uha-6s-mkii-and-gear-purge-stuff.54025/
