Hi Peter ,

did try your setting last night , and it was very much more musical . I did listen to "steely dan - alive in america " and " Ed Motta - Poptical " among other albums .

Only one thing was that it didn't play the complete album , instead it stopped it randomly at the end of the second track or fouth track and so .
My settings were in unattended , minimized , and running time .

Glad that I have been of help Ed , and also glad to hear that the WAVEIO driver manages the ArcPredict , I guess then the upsampling to 88.2KHz will be fine .

Very interesting ,

thanks

stefano

welcome Ed ,

it depends , if it is a Windows driver or a "propretary" driver from Buff ...
To understand that better , try also
a) set DAC is... say... 32bit 96k
b) use Antiimage filter and set 96kHz or 192kHz only button .

That should allow KS for more than 1X upsampling .
c) try 24bit  only dev.  button .

Imo it should work , otherwise the driver would not allow anything but 44.100 , which is rather uncommon by my point of view .

Edit :
I see there is an USB to I2S interface , so that enlarge the options to where to look at ...
d) realize the effective "format" of the receiving BUFF dac
e) re-apply a) b) and c) to the USB to I2S interface .

Hi Ed ,

Did you try some Q1 and some buffer lenght settings in #4Engine ?
Also which KS Mode ?

Hi Peter and All ,

I have a question regarding the buffer size .
The device ( M-Audio , Fast Trackpro ) has the latency slider seletcable from 128 to 4096 .
From a forum I did read a thing about a 2x "effect" on the latency settings ( which I didn't quite understand ) so after that trying the XXHighEnd trik , I did try to verify the latency of the device by the means of that method .
Then to 128 buffer size , Adaptive Mode and Q1=0 there is some buffer error ( audible ) but without XX telling me .
Letting the M-Audio buffer to 128 and encreasing the buffersize on XX to the next level , 256 , it does plays without audible errors .
This until reaching say 1024 or less , I believe .

Should I conclude that I have to consider the buffer size of my device with a "2X" on the XX side?

Thanks

stefano

PS : will 09-z7 include the button Arc Predict and PeakExtend ?

 

As and example , I very often put thermistor in the mains ,in my amps and sources ,  and it works for me . Did today for the monitor and the pc PSU.
CL-60 I have got them from Allied Elect.

Yeah , that is the nature of ground loops , you don't need the hum at the speakers to recognize it .

I will investigate also to my monitor , or build myself a dedicated ps for it ... The major problem is that we are not able in pratical to modify the PC grounding scheme (imo) or at least that would be too dangerous to do .Well not so much for the PS , but more for the MOBO ( and I would know what to do lol )  But many things here are depending on other things ; cables ... amps ...

But when we listen to music , we know that IT IS a very good piece of work alright now . Then let's not forget as Peter said , this is also "thanks" to the contribution of all the people right on the forum pages , discussing and reporting about their own experiences with the software *and* the music .

Having said that , I would be proud to accept any decision regarding the licence in the future .

Of course , by the fact we partecipate to the forum(s) , we want to learn new things and take decisions regarding hardware and lots of other stuff . So thanks, all of you in this wonderful forum .

WoW ! How Fast ! 

Count me in aswell.

thanks

This is indeed a nice post I did enjoy reading Peter .
It is like when building amplifiers , we can be "topologists" and it is quite different than tweaking an existing design .
When something makes our living happy with, is both for the possibly to choose ( that transistor caracteristics... ) or that we like the sound of a particular form of power supply . But usually we can explore and talk about the reasons for that we can like better that topology instead of another , and why it may be simple or not , or not semplicistic . 

For example of the USB 3 , last night I did play with the Renesas driver few options that are : using or not the power management , or try the last driver available .
It's hard to descrybe how all of them produced different sound presentation in different and not so obvious ways .
For example , in my case I am about to say that *using* the power management ( with the 2.0.34.0 driver)  , I do enjoy music very easily on the other hand it not allows to go to Minimized OS ( for me ... but I'll try more) and should  imagine something is going on with it .
Moreover, I did try the very last driver available of the Renesas USB 3 ( the new 2.1.32.0) and it was like completely another system of listening . And for that, can't explain how  .
 I am with you . :-) will wait for the 0.9z-7 .

I have Nokia C6-1 with Symbian , and also have a bluetooth device key for the usb from the past ...

It's  a matter of bandwith probably ; so then the refined timings lend to a more relaxed listening .
I like to reason in analogy to my amplifiers , which ar both very large bandwith , fast yes , but also particular in topology and super enjoyable .
So instead of overcloking we could *infact* think of underclocking .... at times . lol

OK  let me present  my Pc for High End  :

Processor :
Intel i7 2600k at 3,4 Ghz , 4 cores , Hyperthreading , Sandy Bridge , Socket 1155

Motherboard :
MSI Z68A-G43 (G3) with USB3 ( Renesas driver )

Memory : Kingston KVR1333DN9K2 16GB (easy to overclock and looks stable ) .

CPU Cooler : Cooler Master Hyper 212 Plus (set to minimum speed fan )

Disks : 2X Seagate Momentus Laptop ( OS and XXHighEnd ), 1X Samsung Laptop(Music)  . Sata . Will upgrade to new and better Disks later.

Case and PS (400watt ) are generic but good . Later will upgrade PS to a silent one probably from Corsair .

Graphics : Internal , no overclock .

OS: W7 , sp1 from updates ; It still gives the 15msec resolution .

Wireless mouse and keyboard by Logitech .


Well I am very happy for now with the set up , which was all in a look to save some money ( thank you Peter for suggestions of the CPU ) .

The only problem I encoutered initially was the impossibility to go into Minize OS correctly . After some trial and error with the BIOS settings  , it works very well again . I did disable the UEFI boot over other things .

Another thing I did noticed is the DRAM timings ( and overclock ): they seem to produce different sound presentation .
For now I am not overclocking the RAM , and use a timing like 8-8-8-20 . Also the timing suggested by the MSI memory-z works very well ( and it is rather defined with 10 values to set ) .
Some spare tests with the Latency checker , shows values as low as 8micro seconds , and overall the PC is very very smooth at use .

Great , thank you all around !


Stefano

Probably because the the PS need to be connected to the mobo to be turned on . This is my guess .

s

Edit ; we should take a look at a generic PS schematic and find out what is the circuitry that provides the turn on and see if we can do a little mod to do that from the MB or a molex itself .

Here is an example :  http://www.pavouk.org/hw/en_atxps.html
