Hi all,

I agonized over the tweaks a lot and most of them are really effective and of exceptional value. But the success depends much on the individual hardware. Looking ahead there should be hardware which is reduced to the essential functions, which avoids the use of multi-purpose ICs and switching PSUs as used in modern PCs. But that's a matter of time and money and a dream actually. If the actual tweaks are helping so much what could be possible with specialized hardware?

Hi Peter,

that is a really fine and challenging idea! I would go a step further and try to get some people of this forum community involved in the process and open something like a wiki for documentation - it should be moderated of course. Master language could be English but sometimes there is enough energy to get the wiki translated into other languages.

Regards,
Georg

Hi Nick, hi Juan,

actually I'm switching from Juli to USB transport. I ordered the same card as Nick and I am using the same driver and disabled the Mobo USB 2. The chain is: USB 3.0, standard USB 2.0 cable as used in recording studios, USB 2.0 Hub (cut the 5 V and replaced by battery), pluging Hiface via male-male adapter directly into the battery powered DAC. It's a remarkable evolution in musical details.

Hi all USB aficionados,

I tried to follow the discussion and try to summarize for me:

• Don't mix up active devices with USB 2.0 and USB 3.0. Decide for one of them.
• If using USB 3.0 it's not recommended to connect DAC and Harddisk to the same controller
• If adding USB 3.0 PCIe cards take two separate ones if you like to connect DAC and harddisk to USB

Is that right?

Georg

We love your imagination 

I brought this one with me from my last flea market visit. I'm collecting for years medieval music but this Suisse live Radio recording is without any limitations and refreshing unperfect at the same time - directed by Rene Clemencic.

Hi Peter,

very interesting. Dou you think that the barometric pressure could influence the listening experience in that way too? Should we open all doors for best results?

Regards,
Georg

P.S.: Hopefully not to find doors with the same resonance frequency 

Hi Peter, hi Russ,

tried to not mix up software and hardware actions and find out: Unchecking the "decode HDCD" and I was halfway there. Increasing the digital output level does the rest - problem solved!

Sometimes my DAC has problems to synchronize with the incoming signal (SPDIF) timely and a small part of the track is missing. XXHighend should be able to add a configurable synchronizing sequence added in front of the track.

There is additional information based on the HD images I used during the tests.

My first installation of W7 was a bit "corrupted". I forgot to disable the automatic update function and got a somewhat "newer" system than SP1 (Date was 4th of December 2011). Seemingly I discovered that the KS driver was working correctly with red book specs (after doing useless things in the driver setup area of windows) but XXHIGHEND used WASAPI automatically after setting oversampling. (Strange, I know). To get KS driver working again I had to reboot the system and do the same procedure again. If shutting down and starting the system again with this settings the KS driver was working again without intervention. Identifying KS or WASAPI is based on the interrupt latency setting: 15 ms was accepted by KS but not by WASAPI mode.

The second installation contained a "clean" W7 SP1. Here I tried the actual Juli drivers and dicovered that KS was working for the analog outputs only.

After changing the drivers and selecting "wave2" (which was not seen before) in the second installation everthing works as expected.

The driver only, done nothing more ...

Cheers,
Georg

After using the driver overnight everything looks fine 

Hi Russ,
works fine , thanks a lot! After this driver mess I think future will be USB data transport ...

Cheers and a pleasent day,
Georg

Thanks, Peter

Hi Peter,

you are right, I'm using the SPDIF output to feed the DAC. 24 Bit only gets STATIC definitively. That's not the reason. The XXHIGHEND settings worked fine for the XP based system but not for Win 7 64 bit.  I found out additionally: If the system does play tracks with the KS driver it uses the analog outputs of the Juli card! It seems that there is no KS driver for the SPDIF output with the 64 bit drivers of the Juli card. Only WASAPI works to SPDIF. Hopefully anybody has some more experience with the Juli card and the 64 bit drivers?
