Sermo: I, too, do not see any such "bump" on either the L or R exterior of my Arya's.

I have been interested in audiofile headphones since first joining Head-Fi in 2005. Over the past two decades, like many Head-Fiers, I have bought, sold, and traded a number of products. My current collection includes: STAX SR404/SRM313, Senn HD650, Sony CD3000, AKG AK240DF, Westone W4, and now...

I own the USA-6S.MKII and can report that is an excellent DAC/AMP. Previously, I had an iBasso D-Zero that was noisy (GSM, et al.) and encountered lots of unacceptable interference, especially using the USB connections. I got "zero" help from iBasso tech support. They continued to insist that...

  FWIW, I have a non-rooted Galaxy Note 2 and use mostly Pandora, Plex, and Winamp (Shoutcast radio) as players. I run the Westone 4's through a Leckerton UHA-6S.MKII (DAC/AMP) via USB audio connection on the Note 2. 

  That has certainly been my experience with the Comply P100's - excellent insertion, comfort, and fuller sound (deeper bass) than with any other tip I have tried. 

Quote: I am a huge fan of the Comply P100's (Med) which are deeper and provide outstanding penetration and sound.   To keep them in nearly pristine condition, I clean my ear canals before insertion and it only takes a few seconds.I wet my pinkie fingers and gently moisten each canal...

Quote: UPDATE:   I sent an email to Nick Leckerton asking about optical audio processing with the UHA-6S.MKII. Below is his informative and enlightening response:    "The UHA-6S.MKII does not decode compressed audio formats such as Dolby Digital. I think many TVs output this type of...

Quote: Once I detected that it worked, I disconnected and didn't listen long enough to develop any impressions. For the few seconds that I had the headphones on, it sounded clear, but the channel was set to a morning "talk" show, which would not be the best test for SQ. I'll try again when...

Quote: False alarm! I tried the same connection on a different HDTV using the attached soundbar's optical cable. It worked great! Clearly, there must be something wrong with other HDTV's optical port or the cable I used.   Ken

Quote: Well, tonight I tried to connect one of my HDTV's optical OUT to the Leckerton UHA-6S.MKII optical IN and could not get it to work. I switched the TV's audio signal to "External" vs. "TV Speakers," but there was no sound through the Leckerton's attached headphones. I then tried the...

Quote: I was wondering if I could connect the optical out from a HDTV and then listen to the audio via headphones through the Leckerton.    Similarly, under what circumstances would one ever use the COAX connection? 

I did start a new thread and just updated it with some new information covered in the following post:   http://www.head-fi.org/t/673710/intermittent-usb-audio-interference-on-galaxy-note2#post_9685461   Ken

Further Updates and Bizarre Occurrences:   I recently decided to upgrade my iBasso D-Zero (For Sale) to a Leckerton UHA-6S.MKII primarily because of its better internal shielding design against interference of all types. I purchased a HakShop micro-to-micro USB cable to use with the...

Problem: Intermittent RF-like interference with USB audio streaming Equipment: Galaxy Note2 (SGH-I317) connected via USB (OTG cable) to iBasso D-Zero Carrier: AT&T ROM: Stock (not rooted)   Has anyone else noticed this problem? I posted this issue to another thread for Galaxy Note2, but...

UPDATE:   I just discovered that there is a setting in the Galaxy Note2's Advanced Wi-Fi to check for Wi-Fi availability when connected to Airplane Mode.   So, there is no need any more for that Airplane Mode Wi-Fi app -- uninstalled!    Ken
