USB 3.0 gives +50 mega SFS . My listening is relaxed sound and better ....

Thanks to you  Peter 

Recently , I changed the RAM bank in this old Laptop of mine .
For long had the suspect that the little system suffered some "bottle neck" effect from some side .
So that , changed the 2 gig to a more comfortable frequency ( higher than the previous ) and it started to manage well some obvious things , like the better audio and video .


The " non up to speed " systems mentioned in your reply above , reminded me to try again the " power settings " which are in the laptop ( every laptop? ) and under W7 , by pushing the battery icon .
And what I found? ... that the cpu was working at almost 40% of its possible speed . I never pushed to full speed before , simply because the old ram bank - by my point of view - was not "interacting" well for the system .
Now , with the CPU at 100% XXHigh End  to an SFS of 80 , has been able in Unattended mode to let me listen almost the complete album with only one interruption .
It's not perfect yet , but the sound is starting finally to go out through the speakers , more depth and bass and detail , and ...  in Special Mode .
Well a good achievement for today , and let say the problem is "solved" for now . 

Nice learning experience , and looking forward for a new PC anyway .

I may add one thing : it *sometimes* happens that when Unattended is not pushed , and soon after the request for "play" the player gui disappears from the screen , and can't be recovered . It will be still in the processes , then the music starts . After some minutes , but not always , the gui returns as if it was minimized on the bar .

Hi Peter , I am back after a test :

Dac needs are 32 bit , and I confirm that the playlist area is composed with just one album of the same format . Then let's try .

Buffer Size =1024
Q1=14
PP=low
TP=normal
Sfs=150 , SC

I am able to tell you that sometimes it goes wrong also in the middle of
a track .
@Unattended the same problem happens , and even during the playing of the single track , then I have to stop by the means of hot key .
Sometimes the system plays the full track completely well ( it depends probably on the memory settings imo )

Looks to me like the system is close to its limits , since it tends to "loose synchronization" also when I -touch the player- ( it does means when I scroll the playlist menu or the settings menu during the playback ) .

In Adaptive mode , everything works perfectly also with very long playlists .

Thanks again

Stefano

Hello Peter and All ,

From my current and limited system ,

all works fine itself , except when I try to listen to the special mode .
At a given buffer size , say 1024 , scheme 4 , sfs 150 mixed contiguous  or straight contiguous  ,well I just could listen one song at a time correctly .

When XX goes to the next track in the play list , distorsion occurs as very low pitch and rumors .
If I play stop and play again the "new" song it can be reproduced well .

This just in special mode .

What could I do to address the problem ?

Thanks

Stefano

Hello Peter and All ,

I have a question for the next version . since the last one is working so well now in my pc ;
Will I have before install to turn the system back to the original state from the minimized os ?
I guess the instructions will explain me all , but I am getting curious for the new changes 

While Battery power probably offers more " isolation " ,it  doesn't *necessarily* work for better noise and sound specs .There are few examples of experiments  where it is demonstrated that Batteries can be more noisy than Power Supplies .

That said , in my laptop I changed a little bit the grounding scheme , for good reasons .

I guess in my case , the interface would process 32 bit data , then the dac "only" 24 .

No idea really , if there is truncation or not or ... editing post , yes ...there is . Anyway I will set 24 bit needs and listen .

Hi Peter and all ,

the situation in the attacched screenshot , does denotes if all will be going alright? I mean not knowing if the dac really processes 24 or 32 bit ?
Anyway I seem to hear some difference in sound when the DAC is 32 bit 96K , rather tha 24 bit 96k while the dac need is still 32 bit .

Thank you

sb

For me XX high end is much much better than c-play . Better focus better and correct dynamic . Soundstage !

By the way I have "got " c-play working under linux , with asio driver . Crazy no? :-)

Nice reading Peter ,

I think we should be documented in consoles and their inside circuits to have an idea of what was happening after all the manipulation ( and this is the thinking of the analog era ) . Me-today I tend to listen with relatively low gain amps , most of the time no-negative feedback and as a result surely not op-amps . I am not talking about chip amps which I decided to not put in my listening experience todays ( diy guy here )  . Many of the market-level amps are after all op-amps themselves around their circuitry , and there is still confusion about polarity of the signal , which seems to be a problem for some designers to respect or advise of .So it's not so difficult to back-imagine what are the results of op-amps manipulation just when listening with a non-operational amplifier , but this doesn't happen everyday .  I remember once I had to work with an all op-amp mixing console and recording ( analog ) , and it was absolutely impossible to obtain a good result out of it . The excessive gain of the stages with further use of negative feedback rendered the sound unusable .
In the Non oversampling design ( back to digital ) but also in the oversampling zone , using output stages with no feedback is very interesting also , especially cascoding the Current-output DAC . I must say today I would be very curious to try that together with XXHigh-End player and listen .

Hello ,

It is a Genuine Intel  T2130 @ 1.86GHz  1.87GHz .

Having it from year 2007  I am still pretty  with 

Yes indeed !!!

Received this message though : "interrupt mechanism out of order ; notify XXHiHend development ( restart playback ) .
Then I stop playback and press "ok" on the message .

I am playing  minimize os now , but left on the wasapi services .


stefano

Jaja ,  it's ok now !

Good question , not sure if I respond correctly but probably not , I didn't received the messages in that situation .
Now I understand better the function of the new Off button ; anyway is it possible that after Off function activated , the playback just doesn't start anymore , but  *it will* after lowering the SFS without rebootin ?

Just guessing

Stefano

Edit , Have try the off button , and start again the playback and it plays , SFS 70 MC , SFS 70 SC and also SFS 90 SC . So that seems good ...
