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)...

I can't see how comparing $700 IEMs to $200 over ear headphones is a fair comparison.  To my years the best sub $200 headphone I've heard is the AKG K553 Pro and while sounding fantastic for the price of a closed headphone doesn't compare to my Earsonics Velvet at $600 which is what I paid for a...

I'm absolutely loving the overall sound including the sweet and punchy bass in my Earsonics Velvet.  I have them half way in between 1 (tight) and 2 (balanced) setting and the bass is still pretty amazing.  The fit is a little uncomfortable at times though.  I'd love to know recommendations in...

I'm sorry if this was asked and answered before, but I can't find it in this thread...   I'd like to know if the RSA/ALO Kobiconn 4-pin output of the X7 is planned to be configurable as a balanced line out, or will it only be amped by the internal amp?  I have an RSA SR-71B and I'm looking for...

Never mind.  I gave up on Windows...  I loaded the songs in iTunes on my Macbook Pro and then copied from the iTunes folder to the AK120 connected as a USB drive and the tags show up fine now in the AK120. Windows + iriver Plus 4... meh.  I'm not sure what iTunes did automatically to the files...

I recently picked up a used AK120 off the for sale forum and so far I really like it.  One thing that has me scratching my head which I could help with resolving is about AIFF file tags not showing up in either iriver Plus 4 nor the AK120.  I've tried downloading Kid3 to figure it out.  In Kid3...

The guy I bought my AKG K1000 from demo'd them on a S.E.X. for me plugged in to the speaker binding posts with the AKG supplied adapter wired to some Monster banana plugs. I'm not sure what impedance the OT was tapped at.  It sounded really good.  I bought them...  I remember the bass being a...

I'm doing burn in now by running it off of an old Android phone on infinite loop and driving the AKG K553 Pro which also need some burn in time.  I've read on the BH forums that caps need around 100 hours of burn in.  The nice thing about the K553 is that I can flatten them with the drivers down...

I finished my Mainline build.  I did the resistance and voltage checks, plugged it in to my Schiit Bifrost Uber and it worked without issue!  It's completely stock other than the paint and wood varnish which you can see from my previous post earlier in this forum (reposted below).  I did no...

Whew, I finally finished my mod. It took me long enough!  Here's a quick breakdown of my mod.   Step 1 - breakdown I disassembled the headphones, unscrewed the plastic cups from the headband, opened up the cups, removed the drivers from the cups, removed all the current cabling, and marked...

The ATH-m50 turn both ways, which is nice.  When wearing them on the airplane, I can quickly take them off, turn them to rest on my chest, order my drink, then flip them back on again... Super convenient.  At my office desk, I listen to HD650 with a Valhalla amp and Bifrost Uber DAC.  These K553...
