Here’s a new feedback today. He sent me his impressions in less than an hour after the delivery and sent me a proper feedback a day after like this.

Hi Keetakawee, thought I’d drop a few words on my Fidelizer Pro experience, for what it’s worth. I just replaced a 2002 HTPC with a laptop for the internet and a Hollis Audio Labs MS-3 fanless mini-pc music server with Windows 10. I’m using JRiver for my 15,000+ album hard drive library. Before I used Asio4all with Windows XP but now I’m able to use WASAPI for my Empirical Off-Ramp 3 USB Converter. I also use an Uptone Audio Regen for regenerating the USB signal ahead of the Off-Ramp Converter.

My new MS-3 dedicated music sever was a huge step over my old “do it all” HTPC and with free Fidelizer, i was already in audio heaven. But all my friends tell me either get the Fidelizer Pro or the Audiophile Optimizer. Well because I’m not all that efficient with a PC and I didn’t want to mess with things that are over my head, the Fidelizer Pro was an easy choice for me. 12 straight hours of music listening nervosa later, I’m taking a break to write this up as I can’t listen and being able to gather my thoughts to write also. The music is so enjoyable that it demands your complete attention with no distractions. While I really enjoyed your free Fidelizer purist mode, the Fidelizer Pro Purist mode is a completely different beast. I can go to the other side of the house and the clarity gains in the music are still quite evident.

Frankly Keetakawee, I can’t see where you’d ever be able to improve on what you already have here but please, feel free to try. hahahahaha Thanks for providing audiophiles with such an awesome pc audio product that’s so consumer friendly.

Cheers,
Robin

I didn’t imagine making Fidelizer to be so simple yet so effective like this before. We sure came far. 🙂

Here’s another feedback today. This time it’s from Fidelizer Plus customer feeling the real sound.

Lucifar I’ve had a conversion — Fidelizer free definitely makes my music sound better. It’s the audiophile thing, the sound of the music.

But the PLUS! It makes me enjoy the music for itself, never mind the audiophile thing.

And now he’s considering Fidelizer Pro to enjoy the music itself more, as I am now. 🙂

Windows 10 Creators Update’s UAC2 driver – Is it better than OEM driver?

 in Article

Warning: This is purely subjective listening tests. Please keep in mind this is personal opinion and speculations.

I’ve been eagerly to test this for a long while but I have been so busy lately with lots of things to do now. Today I finished some works and have some free time to do some small tests. I’ll use Hiface Two to test between new UAC2 driver in Windows 10 Creators Update and M2Tech USB Audio Driver.

Windows 10 Creators Update’s UAC2 Driver: It works. It doesn’t sound that bad. I find Windows 10 sounding a lot similar to Linux/OS X now. Maybe it’s sound from mapping to UAC2 interface in firmware. Hires and DSD DoP formats worked too.

M2Tech USB Audio Driver: Are you kidding me? This makes Windows 10’s UAC2 driver sounds duller. It brings better transparency and cleaner sound with this driver. I also enjoy music better with improved transient attack and slam of dynamics.

The sound improvement is no less from Windows 10 v1607 to v1703 to my ears. If you set to streaming buffer to Low Latency option, it’ll sound much more closer to real instruments. It’s a shame that OS X/Linux audiophiles won’t be able to compare and experience this greatness.

Since the result is so obvious, I tried to find the reason why and this is probably why. Here’s how Windows 10 Creators Update’s UAC2 driver works.

UAC2 OS driver -> UAC2 interface driver -> kernel driver

Windows 10’s UAC2 driver will route to UAC2 interface provided in firmware to interact with actual kernel driver. This UAC2 driver is more like a mapper to UAC2 interface driver in hardware device. And here’s how M2Tech USB Audio driver works.

USB Audio driver -> kernel driver

Native UAC2 driver will interact with kernel driver directly. It can stream 24/192 format at 3ms latency. I tested “Minimum Latency” and I can stream 24/192 file at 256 samples as advertised. Impossible on UAC2 driver.

This generic UAC2 driver thing is good to have. It can make Windows based server solutions much easier for those who can’t build a real turnkey Windows based server like Nimitra. However, I recommend to use OEM driver because it’ll be better for most of the times.

Here’s a new feedback today. He’s using Fidelizer in JPLAY dual PC setup.

Dear Keetakawee Punpeng

Thank you very much for your excellent product “Fidelizer Pro” you sent to me. After downloading the file, I immediately installed it on my audio PC, part of my dual PC audio system. It has worked miraculously and I have found the sound quality of my music system improved drastically. It is far beyond what I expected. Since I started my endeavor of PC-based audiophile journey, I have now come to its near perfection. Thanks to your state of the art product, I have obtained the most precious sound reproducing system I have ever imagined with such as a low budget. But… you know, human desire is never ending. Now I feel my craving for even higher level of perfection welling up in me. I want Fidelizer Pro to be installed on my Control PC, too.

Thank you very much in advance.
Tadami Yamaguchi
