Just to answer my own question: The best mouse is no mouse.

Just try it.

I've noticed that SQ of the NOS1-USB is compromised by any other USB port that is activated. This may be a mouse, memorystick or whatever USB device. So I like to keep my USB clean, but now a "challenge" rises: how to connect the mouse on a modern motherboard?
Like many new motherboards, my new one only has one PS/2 connector that either supports a mouse or a keyboard. Nope, the splitter does not work (only on some older laptops).

In order to be able to unplug the mouse when listening to music, the keyboard is occupying this port (XX control is via keyboard hotkeys). This works but is inconvenient.

In an attempt to adress this inconvenience whilst not using USB, I reverted to the good 'ole serial mouse on the COM port. The PS/2 and COM controllers are on the same chip and everything worked right away (huray for W7!).
Unfortunately no surprises here: everything seems to matter, so does the serial mouse. It leaves a signature on the sound that is noticable (by me) yet different from the usb mouse.

Maybe someone has found a covenient and harmless solution for controlling the pc with a mouse other than buying a new mobo.
(registry tweaks? more hotkeys?)

Please let me know,

regards, Coen

I can think of a keyboard that has a "pad" for using a finger (like on a laptop), but I am not sure if it carries a PS2 connection...

Thanks Alain,

I have a whole box with mouses, keybords and the like. The more practical (wireless) and advanced stuff is allways usb. Usb seems to be the preferred mouse connection since 2001  unhappy.

Since I am actually right in the middle of this stuff ...

Let's say I will make something that shuts off the USB ports concerned on command of something else. And on again.

I am not 100% sure yet whether this can be done with specific USB ports, which to me seems a necessity.

Notice :
What I have thought of "strategy" is that USB3 is of vast importance to overcome the disc storage problem. So, when internal SATA ports are occupied, USB3 should provide sheer infinite extension.
At this moment I use a mobo with 2 USB3 ports and when two 7 port USB3 hubs (which exist) are connected to that, this gives an extension of 14 HDDs (max 2TB each at this time). This looks enough for now ...

I am playing with this connections active for something like 3 weeks now, and I don't see any decrease in SQ. But I never A-B'd it either, so this could be wrong judgement.


Anyway, I have been thinking about shutting off keyboard and mouse for a longer time, but didn't know of a means to activate them again. Now I do ... (I think Happy).

Hi Peter,

This is good news. I hope a satisfying sultion will be possible.

Does it matter that usb3 is still implemented as a PCIe extention?

As we all know, I don't know all. So ... is it ?
And is USB2  not ?

But *if* USB3 is and USB2 is not, I'd say this is for the better.

Coen, thanks for bringing this up. Yesterday I switched from usb to PS/2 mouse and keyboard, I also unpluuged my Hiface which runs to my home theater setup and got a really nice bump in SQ. As you noted a much more relaxed sound.

You're welcome boleary!

Also note that there is different flavours of sata on the motherboard. Some come directly from the chipset and others are tapped off the pci-e bus (like the usb3.0 above). I have my os on the chipset sata and the music on the pci-e to sata controller. Even the sata port that is used may make a difference. If you have some spare time this kind of tweaking is a nice learning experience an may yield in some free sq improvement.

Maybe next weekend I'll have the time to figure out what connections I have and what might work for a new "flavor," that is if my wife has no projects lined up for me. Spent the last two days stripping paint off a dam 1890's hot water radiater in the kitchen. Used some organic paint stripper that you wrap in plastic and leave it on for 12 hours or so. What a fricking mess.........

So, could you specify the mobo requirements at this stage or even recommend a mobo?

Or am I too impatient? I do want to get on assembling my audio pc . . . . Too much

Hi Stanley,

Assumed this was addressed to me ... No. Or at least not yet, or maybe I never will. I mean, whatever I am doing I do with my own MoBo, but also : what I (obviously) hunt for is that whatever solution will suit everybody. I said hunt for, and not "will achieve" ...

But also see my earlier post, where I talked about shutting the whole lot off in the first place. That should be unrelated to MoBo's I think ...

Hi Stanley,

A difficult question to anwer, if not impossible. I set some budget and powerconsumption constraints in selecting my setup. Also important is wheter you want to use the pc for other purposes.

I think there is no real alternative for the Intel gear. You may get a good price on an i7 Sandy Bridge now since Ivy Bridge is on the horizon. It is general consensus that you should buy the processor supporting the most threads that you are willing/able to afford.

As motherboard features I would advice to have at least a USB 3 capability (native on the latest IB Intel chipset) and (if you do not plan to game) an onboard VGA/DVi interface using the GPU since XX is not demanding on the video side. This is all pretty standard by now.

I personally had a PCI interface on my whishlist to later give the PC another destination than stand-alone music server. I also looked into the 2 Oz copper ones that are advertised to have lower supply impedance (generally something desirable).

Oh, imho there is no way around Win7-x64 Ultimate that supports all desired XX traits out of the box.

When all setup you'll be in tweakers heaven Wink. You can tune the motherboard interfaces, the bios, the OS and XX; no more boring nights!!!

May the force be with you,

regards, Coen

Hi Coen,

Thanks for your thoughts.

My computer will be for audio exclusively. I was aiming for the Intel i7 2600 (4core) because of its low heat production, so I can try to use only 1 cpu fan (12 cm) and no case fans. The psu will be passive. The computer case is disguised as an audio component and is naturally vented.

So for the mobo I have 2 in mind:
- the Asus P8Z68V (http://www.informatique.nl/115786/asus-p8z68-v.html) or
- the MSI Z68A G43 (http://www.informatique.nl/115809/msi-z68a-g43-g3.html) which has no eSata but 2 Ps/2 connections.

If Peter knows a way of shutting off keyboard and mouse during playback and activate them again, I think the Asus board is the choice, otherwise the MSI.

Regards,
Stanley

How about interrupting the power lead (pin 1) to the mouse (or keyboard) with a switch. It is easy to modify a cable or maybe even drill the mouse body and put in a mini toggle  somewhere.  This will have the same effect as unplugging the mouse.

Maybe the system would have to settle for too long after the device is depowered.
