I have been trying direct vs Phisolator occasionally going some time back. The Phisolator was best when I tried however these listening experiances were with an intermitent connection problem with my NOS's 10 cm usb link which was really impacting sq without my knowing at the time. The sort usb lead is fixed now.

Recently I have been looking very carefully at ground loops and transformer coupled mains noise at the dac and pc ends of the usb link (this work is being carried out on my x99 audio pc). The fixes in place make a very significant difference to sq at least in my system, they impact the strength and articulation of bass, high end sweetness, midrange tonal warmth and above all SPEED (the impact is very posertive). My guess is this has a lot to do with reducing noise impacting usb d+ d- signals which are themselves quite low level. I am midmway through measurements of ground currents and coupled mains noise but have had to travel this week so not fully done.

With the above as background I will give direct USB another try later this weekend and see how it sounds, based on past experiance I expect the Phisolator to be preferred but much has changed so it will be interesting to see.


 Ps, One point to keep in mind is that Manis USB stream is likley to be of unusual quality his stealth II sq is very different to standard.

Hi Mani, first impression here with my Audio Pc which is not a Stealh Pc.
The sound instead of clearer seems to be brighter without the Phisolator, therefore the Phisolator / Lush combination makes a sweeter sound (without losing clarity).
For now I prefer this combination although I will continue listening.

Best regards,

It'd be interesting to hear others' experiences.

Mani, agreed !

Maybe there's something in my tuning of the Mach III which I obviously did with Lush and Phisolator. And to keep (in the back of your) mind : the Mach II is really showing a completely different sound; ultimately different. And as you may recall, this exhibits mostly in the highs. And now it is there where the difference occurs with the Phisolator in or out. Maybe no coincidence.

Nobody dares to try it ?

Hey Peter, what I'm hearing is exactly the opposite to what you're hearing!

I really was expecting you to say something like, "No way. Too forward. Bass is too lean. Sounds like ultra-low SFS."

There must be something fundamentally different happening between both of us. Due to your using the the Mach III and my using the Mach II perhaps? It'd be interesting to hear others' experiences.

Hi Mani,

Regardless of same mains/PE (but it is), nea

Right from the first second (seriously) this reminds me of a poor USB interface; too much bass and hardly any highs. The bass is annoying in the end (which is after 5 minutes Happy) because not sufficiently delineated (it's messy) and whether you perceive the "highs" thing fully depends on what you have squeezed out of highs in the first place. On this matter it already starts with the extra-extra I have here because of the Stealth III. And that extra-extra (highs) just completely disappears. Of course this can be good to you or anyone's ears and the "sweetness" as you describe it could be a thing to like, but by now such sweetness means deafness because of the stuffed ears feeling coming from it, your brain knowing there is more.

Apart from this explanation, for me it is just a most clear exhibit of poor USB. It is also the most tricky matter because everybody would be inclined to think it is better. I talked about this in the very same realm when the NOS1-USB was about to be born and back at the time it was a pitfall for me too.
On another matter it is nice (for me) to experience that something (the Phisolator) which was worked out in theory and actually was never audibly tested for its merits really (no A-B comparison) works out so well. OK, in this system with these ears. yes

I sure think that others should try it too. It's a night and day's difference.

Transients seem deadened.
(with Phisolator in)

Net, I think it is the other way around, but this could be a tricky thing to observe rightfully. If anything, the transients are completely different - or work out completely different (this is why I just said "net"). If you'd play music with a lot of tingles and bells and crackle, then this is just not there. It almost lacks completely. This tells me that transients are too much softened. That this in itself may let work out e.g. a snare drum "better" is something else, and if so indeed, it should be something else which can not follow really. Hard to see this really "deadens" but the sound will become dead as such (not enough life in it).
Nice semantec word games ...

Kind regards,

Is this with DAC and Audio PC both moved onto to the same mains / PE now ?

Yes definitely Nick. It's what prompted me to try it.

Did not touch Defender, think it is disabled by XXHE?

Where Defender runs (and even keeps on running in MinOS) is a complete mistery to me. I never had to disable it but this sure does not count for everyone.

Thanks for trying !

Hi Arvind,

- Pull the short cable from the U input;
- Move the Lush from the I input to the U input.

You can leave the short USB cable be as it is at the other end (no need to completely remove it - it does totally nothing now).

Kind regards,

Here's a short report of my playing with 'AudioPC' trying to replicate subject error: No success. XXHE starts normally.
I've uninstalled all unneeded Apps that came with W10 14393.0 using Settings + PowerShell + CleanMyPC sw and tried starting XXHE after each uninstalled app. Always normal start.
Did not touch Defender, think it is disabled by XXHE?
