I just updated my Opus1 to the latest firmware and dumped some new digital high rez FLAC songs on to it which are appearing as duplicates and sometimes triplicates in the Artist and Album view.  Anyone else experiencing this issue?  I tried rebuilding my DB, but didn't fix it.  My next attempt...

Well that settles it!  It appears the tag problem I am having is because the Opus1 doesn't recognize tags for either AIFF or WAV.  I discovered one more dowloaded album wasn't showing tags right and it was all WAV files.  After converting all my AIFF and WAV files to FLAC, all my tags work...  ...

  You don't need a driver for Mac or Windows with the Opus#1.  The driver on their site is for the Opus#11.  All you need is the firmware file.   Go here: http://www.audio-opus.com/pages/firmware-update/   Download the firmware file for the Opus#1, currently ver.1.11.00.   Copy the...

I fixed my issue with the Opus1 not reading tags.  The files that it was having a problem with are AIFF.  I converted to FLAC and now they're fine.  So maybe it's an issue with the Opus1 not recognizing tags for AIFF files.

  There's no line out function that I have found.  I've been using my Opus1 from balanced out to my RSA SR-71B and single ended out to my Bottlehead Mainline with good success.  I don't max the volume on the Opus1, but leave it at 140.  I find I get a little bass distortion at max volume.  ...

I tried using Kid3 on my Mac Mini, but since I can only access files on the Opus1 using Androidfiletransfer on the Mac, that didn't work either. I ended up using brute force method by copying all the files to my local HD, cleaning up files with Kid3 on the local drive, and copying them back to...

For some reason I can't open files on my Opus1 in Kid3 when mounted to my Windows 7 machine.  Does anyone else have this problem?  I guess I'll try using my Mac, but I don't have Kid3 installed on my Mac...   Anybody else having problems like this?  Or does anyone know why I can't see files on...

  Yes, I just read that somewhere else the goal of turning the volume up as high as possible on the source device is to get the best signal to noise ratio as possible on the output.

I use my Mainline at the office.  Yes it gets occasional stares and questions about what kind of weird science kit I have going on.     A recent post in another thread about TheBit Opus 1 DAP has me wondering what people over here think about double amping.  The Opus 1 does not have a line out...

  The specs are really close on both, great SNR, low THD, low crosstalk...  The Plenue 1 slightly beats out the Opus 1 in SNR and THD, but at normal listening levels, you wouldn't be able to hear the difference in the distortion between the two.  The Opus 1 uses Cirrus Logic chips (two, one per...

  I don't have an adapter yet.  I am ordering the parts to build one.  I've built high end balanced cables for all my headphones.  The hardest part to find is a 2.5mm 4-pole right angle male jack that is a high quality connector, gold or copper.  First impressions with my Earsonics Velvet are...

I just got my Opus 1 from Amazon today.  I am updating the firmware and loading it up with songs now.  I know why the leather case comes with holes on the corners.  It's a functional problem.  If the corners were covered with leather as well, it would be difficult to push the unit out of the...

It's a bummer for California residents because price with cover, shipping, and tax from Massdrop is only $4 less than Amazon.  I bought from Amazon because I can get it in two days with Prime...  Instant gratification wins!

Unfortunately I don't contribute a lot to Head-fi.  I'm more of a consumer.  I feel compelled to chime in and state how much I love these headphones.  I haven't done a side by side comparison to all of my cans, and I have quite a few including Audeze LCD-2.2, AKG K-1000, Hifiman HE-500...

I haven't seen this info in a single place, so I thought it might be something others besides me are interested in knowing.  Here are the list of DAPs that have a balanced output both in current production and planned.   Current Astell&Kern AK380 Astell&Kern AK240 (incl. SS variant)...
