In Reply to: RE: The saga of my netbook power supply posted by kclo on December 16, 2011 at 19:52:45
Hi KC,nice hints! I've ordered an ADuM4160 USB-isolator in the meantime after having read your post. I've even found out through cics' hint that it is availible right here at home in Europe. What a small world... I'm curious to find out about its sonic properties!
At the moment I'm listening to the new netbook. Even though it's through Vista (moderately tweaked) with the latest foobar and a Musiland Monitor 02US used as an asynchronous USB->SPDIF-converter (very latest drivers 2.2.0) plus a new amplifier with inbuilt DAC (Onkyo A-5VL) results are already very pleasant. A comparison to my fully optimized cMP²-system (no Juli@ though, but Audio-gd's Digital Interface and NFB-2 DAC) plus a nice KT-88 tubeamp is yet to come.
And at the moment the netbook's fully tweaked XP-system including minlogon doesn't recognize the Digital Interface, the Musiland Monitor or an USB-HDD. There's some more fiddling ahead of me, I guess... (though so far no bug has remained unsolved ;-D)I'll let anyone who's interested know about my comparisons, but it will take a week or two at least to be serious. Until then I'm (and maybe others are) curious about all other experience and suggestions related to the netbook-way-to-do-it!

Hi,
Nice to hear that you are moving from a 'full' setup to a laptop; while I'm trying to do the opposite. Not that I am unhappy with the current sound, in fact I am absolutely delighted with what I'm hearing now, what with the recent tweaks by steppe and all, I am getting the sound of my previous full analog gear. (Infinity RS1, Sota Diamond, Decca cartridge etc.)
Please note that if you want to externally power your USB isolator, you'll have to do a couple of soldering jobs. However, because your dac is self-powered, the benefit you could derived from the ADuM4160 might not be as great as mine.
When you said 'fully tweaked XP' do you mean the full spectrum of the steppe tweaks (22+ I think)? If yes, then your USB doesn't work is a given because the full steppe tweaks are not taking the USB into account. You would need to find out what files are needed to enable the USB to be functional and restore them.

Hi KC,
fully tweaked XP is meant only according to cics' recommendations.
I tried to find out about steppes tweaks in the Asylum. Information seems to be scattered all over, and tweaks look extremely aggressive. So its difficult to find a point to start at - would the post linked below make sense???
Have you cross-tested all of steppes tweaks already?

Hi Eunegis,
(This really belongs to the cPlay thread.)
I understand the confusion and I think many inmates would agree. I am confused too. But (steppe and others) tweaks are important.
I am currently at steppe 4 +Jilida 2 + some of steppe's later tweaks (lets call them watchdog, shell32 trim, and 3 mermaids). All these tweaks in totality makes a huge difference. I had went beyond steppe 4 (to steppe 8, I think) but then had to retract because I didn't liked the sound, way too thin. I will venture forth with further tweaks after I setup my multi-partition, multi-boot hard drive. The only way to do these later dangerous tweaks is to have a multi-boot/partition drive and a good backup/restore procedure. But then early tweaks are quite safe.
My suggestion:
1. Go to steppe's earliest tweak post and then start from there:
http://www.audioasylum.com/forums/pcaudio/messages/9/91415.html
read everyone's comment and then decide whether you want to go forward with it.
2. email Julida and ask for his Bitches Batch (a series of batch files to do the tweaks so that you don't have to remove each file/dll manually)
3. set up a mutli-boot/partition hard drive with a backup/restore procedure so that you can go back to a saved backup if something goes wrong.

...by the way:
my DAC is self-powered - but the Digital Interface (SPDIF-> USB-converter) is not! So maybe at this signal's crucial turning point the power isolator may help.
And not recognizing DI, Musiland and HDD is strange since USB-sticks are recognized normally. It may have something to do with the power level on the USBs and those three devices demanding more power than USB-sticks, but I don't know yet, and I haven't heard of any ways to adjust that so far. I believe that's done automatically and can be seen in the properties dialog of each hub.
