Today we have another thorough feedback. He’s using Fidelizer Pro with JPLAY and J River which is quite unexpected combo.

Hi Windows X

I have now had a chance to listen properly with Fidelizer in Extremist optimisation mode + “music server with network support” and to try various different settings in both Jriver 20 MC and Jplay 6.2 with it. This is going from a single Windows 7 laptop via Oyaide Continental 5S silver USB cable to OPPO USB audio 2.0 DAC, controlled by Jriver’s Gizmo app on my android phone.

Firstly I tried various settings in Jriver. I tried Oppo Asio driver, volume set to OPPO and DSD bitstream in DoP format enabled. For Output Encoding I set it to 4xDSD in native format. Jplay was set to Oppo Usb 2.0 Asio driver (engine Xtream, Throttle on and Hibernate mode on).

Secondly I tried in Jriver, Oppo USB 2.0 Dac with Kernel streaming, for bitdepth I used 32-bit integer, buffering 0,50 seconds, volume OPPO BDP-105 USB audio 2.0 DAC, Output Encoding 2xDSD in DoP format. In Jplay, KS OPPO USB AUDIO 2.0 DAC, Engine Xtream, Throttle ON, Hibernate mode ON.

My preference in Jplay has always been Xtream with KS, but in the Asio settings there was a certain delicacy in the treble, which I hadn’t heard in KS. However overall it lost a lot of information that was in the KS settings. In the KS settings, the midrange and bass were far better and the treble was fine though less delicate. In KS the soundstage and depth were much greater. So I am using at the moment the KS settings.

Overall I would say that the Fidelizer Extremist settings have made the single biggest improvement in my computer sound. I think Jplay makes a significant difference as well. Jriver works well as a library and their Gizmo app makes control easy.

Perhaps you could let me know what you think of this? Any suggestions most welcome. At some stage I will definitely go the twin computer route, whether Windows 8, 10 or 2012 server.

Congratulations on a brilliant programme.

Best Robert

From my experience, kernel streaming is direct mapping which has its own ups and downs depending on configuration. Unlike ASIO where it has software driver layer to manage the flow of audio stream data, kernel streaming has no such thing so things like induced jitter will become more effective for better or worse. You can configure JPLAY configuration to tune treble frequency being more delicate. I usually set clock to lowest possible (0.5ms with 0.01 buffer time) and tune frequency to optimal sound signature I prefer.

Here’s new feedback today. He’s using Roon and J River and this is his impression.

Dear Windows X,

Thank for Fidelizer Pro. I have installed it and I am enjoying Roon with more clarity and detail.

Many thanks
Hossein

He also asked me some questions related to JPLAY. They both can be used on any kind of application and work well together.

Here’s another feedback today. He had little trouble about setting up video playback with Fidelizer Pro and this is the result after helping him out.

first i will thank you .for the great help on mail..

i have just now let the fidelizer start jriver,,,and let the maschin be a mediacenter—-and now i works with my music dvd

is it the setup as a mediacenter or is it jriver be started from fidelizer,,there make the difference ??

already know i will tell that i can not live without the fidelizer…

best regard Bjarne

I, too can’t live without Fidelizer Pro now. I tried listening to YouTube through PS3 app yesterday and I missed a lot of things comparing to what I can hear with Fidelizer Pro.

Here’s another feedback today. This time we received quite elaborated feedback from JPLAY user as below.

Many thanks Windows X for the tips.

I have listened to many ‘so called’ audio upgrades over 25 years, including sometime spent myself in the high end audio business, and I cannot recall one as impressive as yours! I had a Japanese partner, who abandoned making turntables costing 40k US dollars in favour of adapting digital circuitry in relatively inexpensive CD transports and DACs 25 years ago as he knew this was the way to go. What you and others, like the guys at Jplay, are doing is taking audio reproduction to a new level of realism. We could not have imagined this even a few years ago. It is really a remarkable achievement!!

Glad to hear our effort is appreciated.  We’ll keep working hard to improve the quality of products and services.

Here’s a new feedback today. This time it’s pretty long but very promising impressions.

Hi Mr. Punpeng,

just a few minutes before I heard the first tones with the Fidelizer 6.8 Pro in Extremist/Single Audio PC.
I have awaited a good improofment…..but my awaitings have been topped!!!

Thanks for this wonderful program. The next days, maybe next Wednesday,
after longer listening I will report more.

Well, thanks and my expirience with Fidelizer in a few days.

I’ll update again after hearing more from him.
