WARNING: DO NOT REPLY TO OR COMMENT ON THIS POST, IT WILL BE DELETED. 

 

I'm going to have to step in here and fill you guys in on a few things. First, someone posted something like "I'm sure the mods will step in if he has done anything wrong". We get 2000-3000 posts made on the site every day. We don't read all of them, so now I've ended up deleting 2+ pages of posts that came from a single one that broke the rules after another post was reported. 

 

Our primary Terms of Service, which contains the rules for Members of the Trade, are here: http://head-fi.org/a/terms-of-service. If you read them, you'll find out that what a MOT can post is very restricted. They basically can't post at all about their products or services beyond answering questions or clarifying information, unless they become a sponsor. I think it is in everyone's interest to read the TOS and see how strict we are. Sometimes I see people post on other forums that Head-Fi is "full of shills" or the like, and don't realise how laughable that suggestion is.

 

Second, I think everyone should read the Posting Guidelines again. I'd say that 99% of the problems we have with discussion in threads going awry is due to people replying to inappropriate posts instead of ignoring (and flagging) them. It's obvious, but self-moderation is better than moderator moderation. :smile:

 

Third, I wouldn't normally make this kind of post, but I'm going to this time, because going back and PM'ing every single person whose post I deleted will take too long. It's off-topic to the discussion, so nobody should reply to it or discuss the topics in it, hence the warnings (to ensure nobody ignores it, which people did in another thread). If you want to discuss it, feel free to PM me.

One reason I believe the Hugo and DX90 are similar is because, IMO, they are quite neutral. I don't know if anything is exactly neutral, as I don't know what that is, since there are so many variations in recordings and what did the original sound like but in sound, in reference to multiple songs listened, there is a neutrality I hear with a slight warmth, that is life-like, not cold or sterile. And yet there are details, a great combination of slight warmth and intricate details.

Back to impressions - Listening to The Who's Tommy - other than the odd transitions from song to song due to the DAP cutting off the end of tunes (it would be nice to have that fixed soon) the soundstage is more like SOUNDSTAGE.... the instruments are all over the place - John Entwistle's bass is so rich - the interplay of acoustic guitar and electric is crystal clear - Moon's drums pound in my noggin...

 

This is FUN (oops - didn't mean it like that) I'm having fun.....

Ryan Adams & Emmylou Harris - My Sweet Carolina  will probably sound amazing on the DX90, too.  I'm really keen to get one so I can join in the listening fun

Why does this happen if it is supposed to have gapless playback?

After several failed attempts to contact iBasso to locate my tracking information, I was very pleased to receive a DX90 before traveling this week.

I've been excited to listen to and review the new iBasso since it was announced last year. I was very interested to compare it to the new Fiio X5, which one of my associates received this past week. Both of these players had the potential to take reasonably affordable high resolution DAPs to the next level.

A little background: I've been an audiophile for most of my 46 years, with a home system built around a pair of large Quad electrostatic speakers. I listen primarily to jazz and pop, and value equipment which provides real intimacy and insight into recordings. I began taking headphone listening more seriously when I had my first child thirteen years ago, when late night listening sessions became a problem.

I've listened to many headphone/amp combinations over the years, and have settled on two headphones which satisfy enough of my critical criteria to turn auditions into actual purchases. My headphones needed to meet my critical listening needs with regards to imaging, soundstage, resolution, and low level inner detail- but for my needs I require closed back headphones as 1) I don't feel right keeping my wife awake all night when I listen in bed and 2) I do a lot of writing in public places so noise leaking in both directions would significantly diminish my listening enjoyment, and probably annoy those around me. I know that closed back cans bring a few compromises, so I've settled on the two sets of headphones which give me the most bang for my buck, and the least amount of perceived compromises. My first set is a custom set of Westone 3 armature IEMs made for me by an audiologist friend of mine. The second set are the controversial Beyerdynamic T5p's- which I will discuss further in a minute.

My most recent playback rig included an iPad loaded with AmpliFLAC connected to a Fostex HP-P1- a combination itself a compromise as FLAC files played back on an iPad, while better than any other file format you can play on the device, were all digitally 'dumbed down' by the digital output of the lightning connector. That being said, it was the most convenient high end option for the iPad, and has given me tremendous enjoyment for the past two years.

I am happy to report that I feel very good about replacing the HP-P1 with the iBasso DX90.

Some listening observations I've made over the past several days, with some comparisons to the X5 for good measure.

Bass: The DX90 has very well defined bass, with just enough punch to not be overwhelming. It's ability to reproduce complex baselines without getting bogged down and congested is reminiscent of much, much more expensive digital gear. There is good separation between notes played on the double bass and the sound of a kick drum- which are often muddied together on inferior gear. Very impressive.

Midrange: The midrange has good resolution, without the artificial boost so many devices rely on in an effort to make them sound more lively. The best word I can use to describe the midrange is 'neutral'. Vocals come through with natural timber, and on better recordings you can hear a richness missing in many DAPs. Ella Fitzgerald's take on 'Signing Off' from her album 'Clap Hands, Here Comes Charlie!' has never sounded better to my ears on any portable device. By comparison the X5 has a more 'in your face' midrange presentation, which while more exciting at first listen, can become fatiguing over extended sessions. Through the X5, vocals can sound glarey and over pronounced- which some people find preferable- but it's not natural.

Treble: This is the one area where the DX90 truly excels. The treble is extended without being harsh. The decay of cymbals is natural and clear. The attack of plucked guitar strings and and drums/cymbals sounds as it should- fast and well resolved . Interestingly, this is one area where the DX90 and X5 sound remarkably similar.

The areas where this player really stand out are in the areas of resolution of inner detail and soundstage- which typically go hand in hand. The DX90 punches way out of its class, and bests even the far more expensive AK120in this area.

Earlier I mentioned the Beyerdynamic T5p's- one of the things which make them controversial is that they sound very differently with different rigs, and some amplifiers make them almost unlistenable. With the DX90 they sound glorious- having almost the clarity, resolution, and dynamics of the Beyerdynamic T1- itself a reference level product. This is an incredible match, negating any need for a external amplifier, and making my portable rig all the more portable. As for the Westones- this player is optimally suited for IEMs- the DX90 having sufficient power to drive them to dangerous volume levels.

All in all, the new iBasso is a remarkable player- besting several devices much more expensive than itself. I like it much more than the X5 (I preordered both- so the X5 will be going back.) In some ways, it beats iBasso's more expensive brother, the DX100-sacrificing a little maximum power output for better low level detail and 'blacker' background. I've never heard the previous DX50- but by all accounts, the 90 is far superior.

Much like the OPPO 105 player (which actually has a very similar sonic signature to this portable player which makes some sense when you understand the basic design principles behind both of them), the DX90 should be regarded as an incredible bargain- offering a real taste of high end sound for a little more money than an iPod.

Now who wants to buy my HP-P1??

A couple more thoughts-

-This device handles Apple lossless files brilliantly, I suspect largely due to the enormous processing power afforded by dual DACs.

-I'm getting about 7 hours playing FLAC files with Beyerdynamic T5p's.

-I wish the back button on the tough screen was a little larger.

-I'm not as worked up about the variable line out. The volume change happens in the digital domain, and appears to be a lossless process. The variable line out will allow me to match the relative output to the other sources in my system.

-There is a slight improvement in the sound when the DX90 is plugged into a USB battery source, probably due to more on demand current being available (this is just speculative)- but all of the people I played it for with and without the external battery heard the difference. The difference was not as clear when charging via USB wall mounted power source.

If true, then that may tally with some people's claimed experience that the DX50 sounds slightly better with certain brands of battery (some of us have speculated that certain batteries may have lower internal resistance and may thus supply marginally higher current, on demand).

Dont know. Seems to happen to a few people. I have not experienced this, to me gapless works flawlessly
post #384 of 3032

I'd like to hear more impressions with all-time great albums like DSOTM, Pet Sounds, Sgt. Pepper's, Kind of Blue, etc...if anybody can speak to this, I'd appreciate it.

Does you track counter goes all the way to the end before strating the next track? This is not noticeable if the song fades out or has silent notes at the end.

But if you look at the counter it always cut the last 2 seconds.

Not using gapless - would that the premature endings of songs cease?

post #387 of 3032

Just put the DX90 I received on Friday up for sale, http://www.head-fi.org/t/715395/ibasso-dx-90, Going to stick with X5.

post #388 of 3032

Has anyone checked if the truncating of playback for the last few seconds of each song is occurring perhaps only with specific sample-rates? e.g. 24/88.2, 24/176.4, etc.?

 

Or only with specific codecs, perhaps?

 

 

It might be helpful if those of you suffering this issue were to post the exact file parameters (sample rate, codec, tag spec, embedded or seperate or no artwork, etc.) so that a pattern might be collated on the basis of multiple users' reported file parameters.

 

 

Just a thought...

I have 16/44.1-48 FLAC and ALAC with embedded artwork no other files in my folders on an exfat formatted 64-GB uSD card. All files I play just cuts off the last 2 seconds. It's the same card I used on my DX50 and has the same behavior on stock 1.2.8FW. Apparently the same card doesn't have the same behavior on Rockbox in DX50.

Edit:

It also happens on 24/96 ALAC files on DX50. I have not tried it yet on DX90 though.

It happens to all my music - and all I did (since I came from planet Apple and have never gone off-world) was drag and drop each artist and all of their albums and songs onto the "untitled" SD card with my mouse on my Mac - all tunes (maybe a straggler or two) are Apple lossless. This could be why when I sort music, if I sort by album - it lists every song (500+) by album alphabetically; if I sort by artist, it lists every song by artist alphabetically; if I list by song, it lists every song alphabetically by name of song - I don't know how to tag these songs so that when I sort by artist, only the artist shows up in the search (alphabetically) - or tag the songs so when I sort by album, it shows the albums, instead of 500+ songs.

 

Some have album art, but really ICGAS
