RIght it remembers one volume level. I wish it would remember two, one for the last setting  for HO and one for the LO. Quite a shock when you forget you have it maxed for LO and plug in your phones. Potentially not cool for your ears or equipment.

They will need to redesign the DAP itself to do that. It's not something a FW update can provide. Maybe they might change the volume control in DX90.

Regarding 1.2.8, the Heaven VI produces a very linear left to right soundstage. As a result, any weirdness in the soundstage is immediately noticeable. There was a fair bit of that in earlier DX50 firmwares. 

 

I spent quite a long time last night listening to FW1.28 from the DX50 headphone out and the sound is just "correct". I am not talking about sound quality - which is good - I am talking about rendering the soundstage in a natural linear manner with nothing weird going on.

 

In this one regard, the DX50 now sounds like Foobar, or an iPod, or the X5 (which got this right out of the gate) etc. That is what iBasso has accomplished and kudos to them. I am pleased.

Not a deal breaker as overall it is a fantastic little device.

I am listening to Willie Nelson, Across the Borderline. . . my god the sound is spectacular now. I always enjoy this recording but with the new firmware, more spacial cues and very solid placement. Much fun!!

Edit: nvm just sent an email to ibasso regarding the question

Done with the update. Currently listening to Depapepe. Ibasso nailed it this time. Low is just right same goes with mids and highs. Soundstage is freakin awesome too IMO. Got no DSD/DSF files. I'm all good with my FLACs.
I love the changes with the touch sensitivity. It automatically removes the selection on a menu/item/artist when you scroll it.
Kudos Ibasso!!

I have to tell you, I picked the DX50, played it for a short while, then tell myself; is this the player I bought? To be honest how the hell have they done it, it just does not make sense on how tunable they can make this dap, it sounds like a different player now, spectacular is the right word. When I get a chance I'll have to try the earlier version again to see if I am not dreaming.

Save your money. The Audio Engineering Society demonstrated that human beings cannot distinguish between SACD (DSD) and CD-DA (16/44.1 PCM) in double-blind trials unless the volume is raised enough to make the CD-DA noise floor audible. There's no point to paying extra for DSD files unless you routinely listen to music at deafening volume levels.

DSD: DX50's new FOTM.

Well, no, they're not. Rather, your ears are, but your brain isn't. This is why the AES performed 554 double-blind trials with a variety of listeners. Tested listeners correctly identified the SACD source 49.8% of the time. Short version: they guessed.

If you genuinely can tell the difference in double-blind trials then please contact the AES. They would love to study you.

As for me... I'm using a Sansa Clip Zip with Rockbox more than my DX50. The Clip simply works better.

You have to keep in mind the methodology of the tests as well as what people in the real world do. The very paper you're referring to, and isn't mentioned in the Wikipedia entry for SACD, also stated*:
Quote:
Though our tests failed to substantiate the claimed ad-
vantages of high-resolution encoding for two-channel au-
dio, one trend became obvious very quickly and held up
throughout our testing: virtually all of the SACD and
DVD-A recordings sounded better than most CDs—
sometimes much better. Had we not “degraded” the sound
to CD quality and blind-tested for audible differences, we
would have been tempted to ascribe this sonic superiority
to the recording processes used to make them.


This is what people in the real world will do: they'll compare an album on a CD to the same album on a SACD (or even the CD layer on the SACD).

Here's what they did in the tests*:


In words, they took a SACD/DVD-A disc player and down-sampled its audio to 16-bit/44.1 kHz in order to represent their "CD-equivalent" audio. Most people in the real world won't do that when comparing the two.


This same thing happens with high-definition audio; there's no audible difference between 16/44 and 24/96+ formats per se in test conditions, but that's not what happens in the real world.

http://www.head-fi.org/t/415361/24bit-vs-16bit-the-myth-exploded


In the real world you can have different masters for a specified form of media. The master for a SACD can be different from that of a CD; the master of a 24/96 file can be different from a 16/44 one. It is for these reasons that people buy "higher-resolution" audio formats.

As for me, I could definitely tell a difference between the SACD DSD layer and the CD PCM layer for this album with this SACD player with a STAX SRS-2170; the DSD layer sounded much more natural and the soundstage was much more spacious.


Likewise, I can hear a difference between a 24/88 HD master and a 16/44 CD one (yes, this should be in the Sound Science section on Head-Fi). ABX Foobar2000 Test Results (Click to show)

The DX50 can support DSD playback now. That's great news! That means the DSD files I have can be natively played back on a device and I don't have to down-sample it to 16/44. I don't even know if standard music converters can convert DSD to PCM.

Soren please cut him some slack, he's a man of observation not experimentation and truly he is entitled not to act. biggrin.gif

Hi Friends.

A question:

what does DSD format extension ends with...DSF ?
