I have been tracing a problem in my PC / DAC and as one of the diagnostics I have added a PCIe USB3.0 card to my PC.

This is something that I have meant to try for a while as it changes the path and the available bandwidth for transfer of data from the CPU to the USB port (note the USB 3.0 card is just running is USB2.0 compatability mode to drive my NOS USB). Now that the card is installed it seems to have quite a positive influence on sound.

Having said this, I do agree generally with Peter that the NOS USB is not especially sensitive to USB interface / cable setup etc. But I do think there is perhaps more than "hot roding" a USB 2.0 card happening here.

[UPDATE I have checked the intel chipset architecture for my PC and the data routes that I had suggested here are not correct so I have removed them and updated the text below]


So with the PCIe USB 3.0 card the move to PCIe bus and the USB 3.0 host controller offer better transfer rates and lower transfer latency ( I think ..).

If you are using a more modern motherboard than I do that already has USB3.0 implemented then it may be that you already have the equiverlent of the PCIe USB 3.0 board. If you have a mother board with only USB 2.0 support but do a have PCIe bus then it might well be worth trying one of these cards. I have the NEC USB 3.0 host chip set and it works very well. I would be very interested to hear if others experience a positive effect from using a PCIe USB 3.0 Card. The outlay is low to give this a go at only £25 UKP.

Sonically I am still pinning down the changes down but I think the sound has lost some digital hardness, bass is better controlled and extended and overall it sounds like the system has had a day to warm up even when it has just been turned on.

Any thoughts welcome.

Nick.

Hi Peter- here are some notes that others may find useful- you can decide whether or not to post:
1 I use the USB 3 output. The USB 2 should theoretically have enough bandwidth, but it does not.
2 Check the on-board chip driver for USB 3. On my board, I had to upgrade for W7
3 Check the memory speed in the bios. My bios set the memory to the lowest speed (default) and I had to enter the correct speed by hand.
4 Use a USB cable rated for USB 3. I was using an expensive USB 2 cable. Today I switched to a cheap USB 3 cable. The difference in top end extension was *astounding*. You will need a USB A to USB B adapter because a true USB 3 B cable is not compatible with the NOS 1 USB input. System is now finally sounding 'high-end'.


This is what I received from an NOS1 customer on March 5th. So, just one day before your post, Nick.

I planned to have done something with it by now, but of course it needs that little converter. So that holds back. yes

Since the main part of this should (could) be caused by USB3 support being active in the OS (I think even in Nick's application), it looks like an interesting development;

I actively use USB3 - from the MoBo and through an USB3 hub - to playback from. This is related to a new XXHighEnd feature for 0.9z-7 which undoubtedly improves sound. That I use an USB3 disk for it is coincidence, but I - or we may now wonder whether USB3 being active in the OS does a couple of things.

Now I must find that adapter ...

Peter hi,

I take your point about the drivers and OS support perhaps changing the way the data stream is handelled. Interesting....

I have been using the PCIe card and drivers for a week or so now and I am confident the setup is for the better now. My comment that it's like the system has had a day to warm up still stands or perhaps the difference is similar difference to that the straight continuous memory makes when changing from mixed continuous.

I will give the USB 3 lead a go and my hot rodded DIY USB lead and thank you to the other NOS customer for the suggestion.

Looking forward to z09-7  Happy

Best,

Nick

I have USB3 on my mobo but have been using USB2 thus far. After a wire reroute I have now connected to the USB3 input. Definitely the sound is better and in the ways that Nick has described. But that is with a cheap USB2 cable I have just ordered a USB3 cable so it will be interesting to see how that performs I shall report back in a few days when I receive it.

Paul hi,

Very pleased to hear that there is a benifit in your system as well.

I am currently still using a UBS 2.0 cable but was not able to find a USB 3.0 cable that has the old USB 2.0 connection at the NOS USB end. Could you post a link to the cable that you ordered, thanks.

Hi Nick - I had to go for A to A USB3 cable. The USB3 B plug includes new super speed connectors and is not compatible with the old B socket.  So I will try an adaptor with it as the email in Peter's post suggests

All the best

I guess you are going to tell me that I have ordered the wrong thing but this

is what I ordered and converts USB A to USB B (old style) of course the super speed connectors will not be connected to anything but this is what I read to be what the NOS1 user in Peter's email had done.  I am not sure why (without the superspeed connectors connected) there should be any improvement but it is cheap enough to try it out.

Besides the USB3 cable is blue and matches the colour of my NOS1 ha ha  Happy

Maybe something like this: http://hiperusb.com/Adaptador-USB-3-0-a-USB-2-0-MicroUSB-AB-Hembra-a-B-Macho?keyword=UY43

Or like this:
http://hiperusb.com/Adaptadores-USB/Adaptador-USB-3.0-a-2.0/Adaptador-USB-3-0-a-USB-2-0-B-Hembra-a-B-Macho

Here there is a huge collection of USB adapters: http://hiperusb.com/Adaptadores-USB/Adaptador-USB-3.0-a-2.0

What I wonder is if there isn“t a bottleneck in the adapter itself or in the NOS1 because the USB 3.0 port in the mb and the USB 3.0 cable transmits data that are later received by the USB 3.0/USB 2.0 adapter and by the USB 2.0 port in the NOS 1.

Juan

Hi Paul,

Thanks for the link, I see what you have in mind. Use a USB 3.0 extender cable (the slinky blue ones  Happy) from the PC then use the converter at the end to plug into the NOS. I will also try this way.

I would be supprised if the USB 3.0 spec connector made a difference anyway. I have not looked at the mechanical spec for USB 3.0 cable but I was expecting to see better shielding and and a higher bandwith capability similar to HDMI type cabling. Since the cost are in the "cheap-fi" range that we both like Happy no problems giving it a go.

Best Nick.

I align with Nick that USB 3.0 cable (A male to A male : hard to find) plus USB 2 adapter (A female to B male that Paul ordered) would make any difference in sound quality compared to USB 2 cable with identical mechanical specification (similar internal conductors, shielding, dielectric , etc). Potentially, cheap USB 2 adapter can be a weak link that can degrade SQ.

To connect to NOS1 via USB 2 B male adapter, pin 5-9 in USB3 connector (http://pinoutsguide.com/Slots/usb_3_0_connector_pinout.shtml) will be floated. Please see attached drawings. However, if we can actually experience better SQ, then it might be that typical stock USB 3 conductors can deliver higher bandwitdh, speed equivalent to those expensive USB 2 cables. It is a cheap try though.

best,
Praphan

I am just now listening to a very familiar recording and there is no doubt about it - USB3 sounds better. Count and Dizzie have never sounded better.

Thanks Nick another free upgrade and the next upgrade (potentially) the AB adapter for £1 (delivered free) to use with my USB3 cable. It may or may not make a difference but hey that is the sort of risk I am willing to take.

Congratulation Paul !

I guess you were using USB2 cable connecting to USB3 port for the listening test. If so, then it has nothing to do with the cable. It is all about USB3 port. Can anyone explain ?

thanks,

Hi Praphan - yes indeed I am using a cheap USB2 cable. I suspect that Nick is close to the reason why it sounds better when he mentions the improved internal USB3 architecture but who knows?.

But what really interested me is this comment in the email quoted in Peter's post earlier in this thread:

Quote
I was using an expensive USB 2 cable. Today I switched to a cheap USB 3 cable. The difference in top end extension was *astounding*. You will need a USB A to USB B adapter because a true USB 3 B cable is not compatible with the NOS 1 USB input. System is now finally sounding 'high-end'.

On first thoughts I cannot imagine why the USB3 cable connected through an adapter should sound so much better but I am looking forward to finding out in the next few days if indeed it does in my system.

What a great hobby this is!!! tweakers paradise.

I can find an usb 3.0 A male to A male but I haven't been able to find an usb 3.0 A female to usb 2.0 B male adapter  scratching

Any suggestions for a source?
