yes 4.05 is definitely chianti. 3.56 is also but with spice. i see not many like this kind of sound...

i like it. calm. actually peaceful.

is the sound width ok? seems compressed

Version 4.05 avx doesn't work on my system (see profile). cmd window opens, first song starts (blinking) as it would play, but no sound. Version 4.05 sse4 however sounds as good (= detailed and calm) as my favorite 3.57 avx. I wonder whether 4.05 avx would sound even better.

4.05>4.04
4.05>4.03

4.04 seems too slow?
4.03 seems too fast? 4.03 sounds like sse2. just guessing

-The PPA V1 card uses another chipset than the V2 and the JCAT card , the uPD720200/uPD720200a.The latest driver for these is 2.1.39 .0 from August 2012 ,that´s the one I use .The Renesas utility app says firmware is 4021,I think also the most recent .I have tried without this driver,letting Windows install a compatible Renesas version ,but this one is older ,from 2010 or 2011 and it doesn´t come with a separate USB 3.0 root hub.Sound-wise I prefer the 2.1.39.0.I think it does give a noticeable lift .I discovered that the Renesas utility app comes with an option to disable USB 3.0 power management function .Must try this out and see if it makes a difference.
-My mobo feed isn´t perfect and likely the Achilles` heel of my Zuma ,but alas ,the maximum of what I am able to achieve-until pension time ...: 12V Teddy Pardo to a PPA Pico PSU.The PPA V1 card is fed by a iFi iUSB and the SSD by a Samsung 9000 mAh battery pack.Not ideal,but way better than the default Zuma.

what version would that be?
I'm running 3.0.23


well i meant 3.0.23 over windows drivers

Nige - I am running DH61DL mobo with stock WS2012R2 USB 3.0 drivers.
Would you be kind enough to let me have a link to the correct 3.0.23 Renesas driver for that mobo?

Many thanks
Jonathan

Many thanks.
When I read the explanatory notes though - http://www.station-drivers.com/index.ph ... 23.0-WHQL/
It was all bug-fixes rather than any upgrade to the driver itself.

But I suppose there is no harm in trying it, as I think I have the built-in Windows driver currently

the blinking is an indication that the application has crashed.
If you check the Windows Event Viewer you will see an Exception code: 0xc0000005 ("Access Violation")

I think this most likely points to a program error where it tries to access a part of memory which it isn't allowed to.
It could point to a windows security violation as well, but I have minimised security, so is not very likely.

For some reason i thought the JCAT and the V1 was the same chipset

The Renesas utility app says firmware is 4021,I think also the most recent

I was wondering that too would flashing to the latest firmware do anything positive not sure if read any reports about that

I discovered that the Renesas utility app comes with an option to disable USB 3.0 power management function .Must try this out and see if it makes a difference.

very interesting have you got a link

Thinking back the default Zuma would chase us out of the listening room by comparison

Your system should work well only thing that doesn't work was ssd on linear and pico on battery just sounds weird

Might not be such thing as a perfect supply, all seems to get complicated looking for power related sq upgrades
Unfortunately there's not any massive lift to be got whilst using the pico
Since your already laden with batteries
Might be interesting for you to wire the 4 pin cpu socket direct from your teddy Pardo and place a 12v sealed lead acid battery 7 amp hour in series on that cable.
It should give a lower noise floor
12v batteries cost about 15 to 20 euro here. so you won't have to eat into your pension yet. :)
Pico on a 12v battery sounds good too incase you get a 2 for one offer

Now we are way off topic :-),but some clarifications:
-The V1 card uses an older chipset than the V2 and the JCAT.I have no idea if this has any impact on SQ.It may have.
-As for the Renesas firmware,I haven´t read any commentaries about SQ related benefits from upgrading-and I also doubt it is relevant-or possible .So best to let this issue rest.
-The Renesas utility app is part of the 2.1.39.0 driver package.So no separate unit and no link.
-I think you misunderstood.I have the SSD on battery,the mobo on a PPA Pico PSU fed by Teddy Pardo 12V and the card on iFi iUSB.Not SOTA,but decent.Presently I have neither the time or skill,nor the space for adding more batteries next to my overcrowded rack.Thanks for the suggestions anyway!
