1  Ultimate Audio Playback / XXHighEnd PC / Re: Phasure Mach III Audio PC with Linear Power Supply on: August 07, 2018, 08:46:48 pm
Hi Peter,

timing looks ok for me as I will be sailing until the beginning of September. So if the Mach III will be finished in September, that would be great.
So, please send me the invoice. Delivery and billing adress as always.

And I would like to try a shorter "lush", like 1m or so. Please put it on the invoice too.

Kind regards

After reading these post I did some tries with much higher SFS values for my Stealh Mach II and reduced Q1x significantly.

SFS = 140.19 doesn't work with the Mach II, it's pretty spurious
SFS = 70.19 brings amazingly good sound stage, but SQ? It sounds too loud, due to distortion I guess.
SFS = 35.19 works nicely when Q1x is down to 2 or so. That's what I am trying now.

SFS seems to be limited somewhere there with my Mach II. But trying such high SFS gave me kind of an idea what it could sound like, holographic, spooky, ....

So, Peter, I need a Mach III. There is no way around I think, althouh this would be my third Stealth already within 2.5 years  scratching
What will be the delivery time when I order one now?

Kind regards

Ok, Peter,

I didn't know that it's related to AP filter.
Custom filter works well with these tracks.

Kind regards

Peter, I had this kind of issues very rarely:

24 bit second stage crack dedect !  -> 34
playback has been stopped

But since yesterday it happend for 4 different tracks. I tried with different SFS setting and it still happens.
All these tracks play well with other players. Nothing strange to hear. I have downloaded these track from Tidal and Beatport, they are no rips (at least they shouldn't be).

Download from Tidal:
Artist: "KMLN", Album: "2015 - Alhambra"
The crack detect error occours for the first 3 tracks of this album.

What's maybe interesting: The first track "Alhambra (Original).flac" I also downloaded from Beatport in aiff format and then converted it to flac. Same thing: crack detect occours for both versions.

What to do about this?

Kind regards

Hi Peter,

after rebooting the max. speed is now 1.8GHz.
Is this value ok?

When playing unattended is goes down as described above.

Kind regards

Hi Peter,

on my audio PC Stealth Mach II (with XEON E5 processor) turbo boost looks like being on, because I see up to 3.3 GHz.
When playing in unattended mode the speed goes down as it should:
e.g. 0.86 MHz with Balanced Load set to 36.
Is this ok like this?
Or shall I try to disable turbo boost in the BIOS settings?
(I never changed anything yet in the BIOS of this PC)

Kind regards

Hi Zheng,

there another new album from March 2018, which is very good for comparing Redbook with MQA. Here in Europe both versions are available on Tidal:

Artist: Nakhane
Album: We Will Not Die

Again, in my ears the MQA version outperforms Redbook in an pretty impressive way: better soundstage, clearer highs, more natural sound.

My dropbox is pretty full, so I will find another way.

Kind regards

Hi Zheng,

hopefully this link will help:

If not, let me know and we will find another solution.

Kind regards

Yeah, I like the cover too!
The recording quality differs though from track to track. So don't losten to the bad ones too much, like the second track, what was recorded in Vienna with pretty strong hum on it  no

Hi there,

that's a very interesting topic for me. I enjoy it more and more listening to good MQA albums with XXHE and my NOS1a-3G. For me the majority of the MQA albums sound significantly better (bigger sound stage, clearer highs and more precise bass) than the redbook and highres versions. I believe to receive well the better timing and/or debluring of MQA in my ears, but that's subjective for sure.

Ok, it depends a lot on the mastering the tracks come from.
In this way I think, very new albums are good for A-B testing, like e.g. Melody Gardot's "Live In Europe" what was released 2018.
We did a-b-c testing of the track "03-Rain" with three versions:
a) redbook from Tidal
b) highres 48/24 downloaded from Qobus
c) MQA 48/24 from Tidal

These versions are most likely from the same mastering, as the track lengths are exactly the same.

The result: c) clearly outperforms a) and b).
There is not so much difference between a) and b) but a pretty big gap to the MQA version c). Especially the basses are much more precise and the highs too with MQA. Some blind testing confirmed these results. My girl friend Alexandra prefers MQA:  "The bass is much nicer...".

Peter, it's great that you implemented the MQA decoding!
Thanks a lot for that!

Kind regards
11  Ultimate Audio Playback / XXHighEnd Support / Re: How to play selected tracks of a playlist without losing the rest? on: April 12, 2018, 12:12:55 pm
Hi Peter,

I can see well all the goodies of the new UI for the playlist using the new right-click options.
Maybe it would be an idea to solve it this way:
- add one more right-clock option like: "Use selected tracks as playlist"
- and the Play button could work like before.

It happened to me a few times already that I unintentionally selected two tracks instead of one and lost the rest of the playlist when pressing play. I surely will survive that, but I don't like it, as I have to save and reload playlists now all the time.

Kind regards

Hi Peter,

I am using XXHE 2.10 since about two weeks now. All works well and is amazingly stable. And I like SQ a lot and MQA and so on...
There is only one point which I miss or maybe just don't know how to do it in the appropriate way:

With 2.10, when I press "Play" after selecting tracks in the playlist, the playlist gets reduced to these selected tracks.
Is there a way to get back the original full playlist?

With the previous XXHE versions I was doing it a lot like this:
- create or load a (long) playlist
- select some tracks and play them
- select some other tracks out of the same playlist and play them

With XXHE I didn't find a way yet to do that without reloading and maybe reorganizing (if not stored) the original playlist.

Kind regards

Hi Peter,

with 2.10 MQA is working well now in my setup, what's great.
Decoding is done well up to 96kHz.
Thank's a lot for your support and the software improvements!

Kind regards

Hello Nick,

all this is very interesting for me, because I had similar experiences with XXHE 2.10 since I installed it more than a week ago.
I agree with all the post above, 2.10 brings amazing improvements of SQ, but I too missed something in the low frequencies.

I have one question:  Do you use the same SQ paramenters for both versions: 2.09 and 2.10?

After reading your post today I did some intense testing again with both versions: 2.09 and 2.10.
I am using SQ parameters with large buffer sizes (see my new signature), very similar to Peter's settings. As many others here I changed to that because 2.09 was too punchy in my ears compared to 2.07. And I was very happy then with the SQ, especially for the bass range.
With 2.10 it went the opposite way somehow. With Peter's actual settings (SFS: 5.19, Balanced Load: 52) the basses didn't sound so well with my audio equipment: louder, but not precise enough, too smooth and mellow.

Today I changed some settings, which brought back the amazing low frequencies of 2.09, still using the high buffer sizes:
- SFS: back to 10.19 (as I had it most of the time with 2.09)
- Balanced Load: back to 43 (52 makes the basses louder but much more unprecise in my ears)
- Nervous Rate: between 10 and 20. I am using 16 right now (with 2.09 this was set to 100)
- I am now using AP (what I never did before)

With these settings I feel no need any more to switch back to 2.09. The punchy and precise lower bass range is back again. With 2.10 the mids and highs made a big step foreward anyway.
And it's amazing how SQ can still be influenced by small changes of Nervous Rate.

Kind regards

Hi Peter,

thx a lot for your detailed explanations!

On both PCs I have got the latest XXHE version installed. That's for sure.

Everything works perfectly for MQA 44 and MQA 48 since I have installed the latest releases. I am happy with the SQ of these MQA albums.
When I look into the ID-tags of these flac files, I can see that the tag ORIGINALSAMPLERATE (44100 or 48000) corresponds with the audio property "sample rate", which is always the same for these wELL working MQA tracks.

When I download a MQA96 album, like the Robert Plant album in the emailed log file, with my audio PC, it is like this:
the tag ORIGINALSAMPLERATE has the value 96000, what seems to be correct. But the sample rate of these flac files is 48KHz only. It should be 96KHz too, as I believe.
I cannot play these files with my audio PC.

kind regards
