"How does the user know which sample rate is being streamed from Amazon?". 

 

I don't understand. If you click on the Ultra HD square it tells you. It also tells you what your device is capable of. So if I play from my iPhone using the Apple dongle it recognizes it's only capable of 48/24. If I plug in my Dragonfly it recognizes it's capable of 96/24. And it always says it's playing at the resolution it was downloaded at--unless it's 192/24 and it has to downgrade it to my device's upper capability. So if I download a 96/24 album it says it's playing at 96/24 with the Dragonfly but only 48/24 when I rely on Apple's dongle or my Bluetooth headphones.    

 

I'm not an audiophile expert, but I'm not understanding the issue. Unless Amazon is lying, aren't these tracks already playing at the resolution they are supposed to be playing at?

 

The information Amazon Music HD provides when you click on the "Ultra HD" square is not correct. My external DAC tells me what sample rate is being sent to it and even when I stream a 192 track from Amazon Music HD Windows shared mode down samples the file to 96 which is the sample rate I have set in Windows sounds. Same with a 44 track it is up sampled to 96. This is why we need exclusive mode playback bypassing the Windows audio stack.

Bluesound node 2i into a Zodiac Gold and the dac always shows the correct sample rate matching that of the file.

Also comparing Amazon to Qobuz I can’t hear any difference in sound quality.


Setup:

Amazon Music HD >Bluesound Node2i> Antelope Zodiac Gold with Voltikus PSU > Austin Trew AT5000 > Focal 806

My experiences:

  1. The interface is awful. I gave it a chance to familiarize myself with Amazon Music (as I've been a TIDAL subscriber for years and I'm used to that interface) but it's just poorly designed and visually confusing.
  2. Downloading on Android is a terrible experience. The downloading often has to be paused/restarted just to work, and will frequently stop. Never had this problem with TIDAL.
  3. Having to constantly pay attention to Locations (all music, cloud, or offline) is a pain when removing things from My Music.

 

I'll stick it out a while longer to see if they make improvements, but I doubt a niche market like hi-res audio is a high priority to them.

Folks shouldn't get upset over 16 bit as opposed to 24; there's nothing extra there that you can hear anyhoo...

Oh!  I get so tired of neh-sayers telling me what I can't hear, what I don't need, hi-res is BS, etc.  I hear differences in resolutions!  So, replace 'You' with 'I', and be done with it!

I respectfully disagree— but let’s discuss why in a different forum topic please.


I don’t want to derail the main thread here which is:

“what is the scope and quality of the new Amazon Music HD service and to integrate it into people’s audio systems.”

 

And I’ll ask the folks want to discuss the value and cost and their judgements of Amazon as a corporate entity to also discuss that in another topic in the forums.

 

Folks please  let’s keep this topic, on topic- it provides valuable objective information to those who are using or considering using Amazon Music HD.

You're right, of course.  My apologies.  He just hit my hot button.

I have been using it with alexa for awhile...i love it.......i have been using it a long time...even before ultra hd...the convenience with alexa makes it well worth it....rarely do i pick up a device, turn a knob, or do anything other than to speak where, when, what, volume, etc...

I have been trying Amazon Music HD using an Echo Link connected to the coaxial input of my T+A PDP 3000 HV. I've used both an Echo Dot and the Amazon Music App on my iPhone or iPad to select and play music. The lsound quality is better than both Spotify and Apple Music. Because I'm legally blind I don't always know what sampling rate or bit depth is displayed on the T+A. As I recall the Echo Link is supposed to support "HiRes" up to 24 bit 192 KHz. 

 

When I auditioned an Aurender N-10 in my system last week, tracks from Tidal  from the Aurender sounded better than the same tracks played from the Echo Link. This was not an exhaustive comparison so there could've been factors such as volume mismatch contributing to the differences I heard.

 

The Amazon music app is clumsy compared to Spotify or even Apple Music, but since I often speak through my Echo Dot to select music for "casual" listening this isn't a big deal to me.

 

I believe Amazon is working to open their API to other server vendors such as Aurender, so if that happens more meaningful comparisons for SQ may be possible.

 

As for Amazon Music HD in the marketplace, this is a positive direction because they have the resources to support the platform and hopefully increase the popularity of at least "CD quality" streaming to more people than audiophiles. If Amazon Music HD leads to more people showing an interest in better sound, we will all benefit in the long run.

Great to finally find another leagally blind person on this site.  Perhaps one day, I can pick your brain to find out about your use of various hi-end sources and/or streamers.

Meanwhile, I'm O.T.  So back to lurking.

So it's half baked...It's not even half baked.  What is it then?  Is it a checkbox  - some committee got together and determined "Hi Res" serves a purpose and the IT boys came up with this effort but neither the committee nor the IT boys know or care if it actually works??

 

Really scratching my head on this one.


Hey MQA, if it is not all $voodoo$, show us the math!

I run my Node 2i into my PS Audio DAC.   The DAC indicates the resolution!  BlueOS needs improvement.  Sometimes I have to search Amazon Music on one iPad and then load the music on Blue.  So it goes.

 Hi, I was hoping that too, but unfortunately it doesn’t support 24-bit at all and peaks out at 16/48 from info on amazon’s own help pages for digital output to an amp etc:

Supported Digital Connection Formats

  • Digital Audio Inputs (optical TOSLINK and coaxial RCA) - Uncompressed PCM audio (16bit/44.1, 48, 88.2 or 96kHz)
  • Digital Audio Output (optical TOSLINK and coaxial RCA) - 16bit/48kHz Uncompressed PCM stereo


It’s interesting (or disappointing) that the Alexa app doesn’t show or tell you the quality when streaming to the Echo Link, unlike the Amazon Music Apps.

 

It’s also telling that they have only just listed their Echo Studio speaker under supported kit on their splash page - no sign of the Link.

 

I think what’s becoming clear is that their own Amazon Music apps aren’t up to the delivery of their UHD service - hopefully they’ll address that as this, and other forums, are clamouring for improvement.
