I read up somewhere that a properly designed DAC can accurately output an audio stream.

There are a lot of music players that vary in price. Dual dac converters. Some are in 500- 1200+ range.

What is point of these? I always see reviewers point out they have "increases details, heightened soundstage and better instrument seperation" than other players.

How would this be possible? If how a DAC works is just to convert an audio stream. As long as the amp is also well designed.

This discussion of DACs misses the highest  technical points related portable music  player enjoyment. The first two technical specs that relate to portable player enjoyment are voltage output and source impedance.  In many cases, one or both are not given by the vendor's blurb, and sometimes they are great, but the vendor is unwisely keeping his light under a bushel basket.

Other factors like storage capacity and format of add-on storage, music file formats supported and ease of use are probably next. Then comes DAC quality which can be broken down into the two most important specs which are dynamic range and frequency response, but both of them are so cheap to surpass the reasonable requirements for that they might even be safely ignored.

Also, relatively sophisticated features like the DIY ear tuning provided by a little piece of software for Android called Neutralizer can be very significant to your enjoyment of your portable music player which well may be a phone or a tablet.

Good find, thanks for reporting.

Looks like these files got their last MPEG frames clobbered by tags; the tool actually to blame for this is either the encoder or a previously used tagger.

So, here's what happens-
Before removal of the tags, foobar2000 scans for the last apparent MP3 frame, finds a valid header but doesn't notice that the frame overlaps with the tags, and decodes it - though decoding produces nonsense as the payload is malformed. This also affects detection of MP3 stream duration.
After removal of the tags, foobar2000 rejects the last frame entirely as its signaled size exceeds the file size, hence shorter decoded duration.

I'm fixing this to prevent future confusion, editing tags should never affect decoded or reported duration, and we should not read into bad data if it can be trivially detected.

tl;dr
Nothing got lost, the data that foobar2000 no longer tries to decode was bad already, editing tags with foobar2000 is safe.

Opus / Re: Point of transparency of Opus 1.2

I think the biggest thing right now is getting it supported in software and hardware so it can be used more widely. It seems to be the way forward.
By the time Opus finally gets widely supported by car stereo manufacturers I'm in.

Though I may turn the tables on my own as soon as I finally upgrade my smart phone to one with external storage support, who knows.

Since then, are those "popclicks" still there with no delay option ?
Actually, I'm routinely using it for encoding video soundtrack. Don't use it for music.

Easy to drive headphones are not all earbuds or IEMs either (a common perception mistake people make far too much)

What about the other way around? I would be surprised if I bought an IEM off the shelf and found out it was too hard to drive, but threads like these are for eliminating unpleasant surprises.
But too loud volumes could be an issue, I guess? If you hit the pain threshold at volume level 2 of 10 (or was it 11?) and destroy the IEM at 5, you have a bad combo.

Is compatibility vs "any reasonable portable headphone" any issue nowadays?
Impedance / available output volume ...?

There's probably a few players that are designed for difficult to drive headphones but my opinion on those is that isn't as worth the money that could spent on other things that are much more worth it.

Easy to drive headphones are not all earbuds or IEMs either (a common perception mistake people make far too much), you can get some good full size headphones that are easy enough to drive.

You could certainly be justified in paying a bit extra for a better UI, larger storage and/or compatibility with more file formats.

Pretty much those are the points that are worth spending extra on.  You can also be justified paying more for a model with a better battery, too.

Storage and compatibility with more file formats are the ones I look at most.  The UI as long as it's half-way decent isn't as much as concern unless it's truly too crappy for me to use.  I usually prefer players that have wheels to scroll through songs, I hate the button scrollers.  If the UI interface is bad I check to see if there is working stable "RockBox" port available and if there's any issues with that port that could affect your enjoyment before passing it up if the storage is good but want to save a few bucks.
