In Reply to: RE: Kernel Optimization: /timeres Redux... posted by gjwAudio on April 22, 2011 at 16:13:18
I have been trying to compose the best manner of describing what I am hearing.I am listening to an iMusici 24/96 download from Linn.com but also tried this with Duke Ellington's Blues in Orbit and Zinman w/ The Tonhalle's Beethoven's 3rd with the cplay resamplers to 96khz.
The thing I am trying to describe is a sense of better defined and sustained features in the sonic shape the sense that the sound vibrations have much greater definition,separation and sustained longevity where their full expression can be discerned.
The music appears far more real with a truer sense of form and cohesion.
I have preserved a few items not used in the full cMp2 set up but had the BIOS settings for CPU and Memory down just kept the USB enabled as I'm using a monitor on that machine but its a virtually brand new Gigabyte H55 usb3 mb with Corsair XMS 1333 RAM (2GB becasue I forgot to yank one stick), Intel i3 540 and a Seasonic X650 PS. XP Pro SP3 ..
cmp enabled; startup=none,AWE and all other OS minimizations set with one usb root hub and controller disabled for the pcilock switch. Used "/UsePMTimer
Its playing into the Resolution Audio Opus 21 DAC over SPDIF over a Canare terminated Belden Digital cable.
I think its a definite Score! Thanks a million.

I could not agree more. I wonder if the change varies based on system. In my case its almost transformational. It is like the computer just sync'd up to the DAC. A digital hash I did not know I had dropped away. Relaxed, and real are words that come to mind. At first symbols, bells etc just jump out and shimmer. Then it was clear that piano and strings have a whole new sense of relaxed reality. Drums and base as well. Liquid. A sense of being there.
I've been perfecting my tube output tda1541a dac. Its like it just got set free. Thanks for a great find.
I also changed timeres to 9766 (which I did together with "/UsePMTimer"). Interestingly, I found changing cPlay's DSP buffer to "Tiny" gave best results (more organic/natural sound).
Will test this setup for a while. Thanks.
I've been using pmtimer for a while and prefer it. Changing timeres to 9766 from 9800 and using tiny buffer improves it yet again.
I can confirm the improvement of pmtimer+9766 in my two systems too. Now I'm testing the effects of kb 896256
Thx a lot
Daniele
PS: I'll try in few days (I hope) a new Sandy Bridge setting with an astounding cpu i3 2100T of 32W only joint with a MoBo Gigabyte GA-H67MA-D2H-B3(rev. 1.1)! Has anyone some experience about it yet?
