I propose that you post your current system's latencies (from dpc latency checker) as well as your hardware configurations. There is a huge dependence betweend your system's latency and SQ. The lower latency, the better SQ. It's not a placebo, believe me!
The lowest value I ever got was under XP SP3 (highly optimized, only sound drivers installed). DPC latency checker showed constant 4-5us. That was on my second, older PC (X2 3600+ @1.9GHz, 1GB DDR II 800MHz at CL3, integrated Radeon X1250, Samsung F1 HDD)
Currently I am using Windows 2008 R2. I really like this OS, since it allows for easy customization of windows features. DPC latency checker shows 20-30us. (on Windows 7x64 I got sth like 130-150us...) I highly recommend using 2008 R2, which is basically more pro Windows 7.

I don't want to spoil your topic, by my latency checker shows a constant 1000us (which happens to more people). Still I use 22 samples of latency (at Special Mode, and ever tried 5 with success) which is lower than 1000us ... Also to keep in mind (and it has been said before) : some people experience a dropping latency from latency checker as soon as XXHighEnd playback starts.   |

Correction :
What I said in the before post is not true anymore. I just checked, and I'm around 100us (between 77 and 117). So, the 1000 always has been so for my Vista installs, while W7 (which I never checked before) solved it. Somehow. Same system, same hardware, just upgraded.
Just to let you know, and with the 1000 the ultra low latency probably isn't possible at all. I don't know now.

Considering that i have spikes of around 1500, yes, ultra low latency is not possible in my case. |

After reported issues on OS latency,
People might want to reconsider their energie settings under power options (power plan),
Low latency just asks for more energy at certain moments.
XX low asking latency settings, could wel exceed some standard BIOS or windows energy settings on several systems.
Using more energy could give that ultra low latency mode you are looking for.(without drop outs)
Just wanted to add this,
Because it seems logic to me, that asking more and faster responsiveness from OS, also takes (create) more energy (spikes).
So "balanced (recommended)" energy setting maybe is not sufficient enough, you can try to use "High performance" instead.
Peter what is your response to this matter ?
OS (or PC) Energy and low Latency are highly related in subject of glitch free playback of xx.

And Telstar,
Your system should have a latency of 7-14us (just xx playing) range, with a max of 200us sometimes.
Even when my system is at full load, it never exceeds the 300us range.
This is with a 9800gtx videocard in there full aero etc,
Try that "high performance" setting !

It is console with my soundcard drivers that causes these spikes. I cannot solve the issue (tried everything together with the pretty good infrasonic support). I have always around 55 without that. I of course have setup the power option the way i wanted them (which is custom, not high power btw). |

Hi, I have a latency of around 1000 when doing nothing and when using my mouse it skyrockets. I have investigated th issue and it seems to be caused by my logitech air mouse, known for high latencies. That's really a bummer because this mouse is great for these kinds of apps (i.e. being able to "mouse" when sitting in your comfy chair listening to music meters away from your PC-audio. PietPara  |

Yes, I'm afraid this is a commonly known issue, and applying to IR keyboards as well.
A bit of a strange solution : Keyboard as well as mouse cables can easily be extended to 15 meters (VGA monitor cables as well, if you have a decent cable). I use that myself.
I never heard someone talking about it, but maybe I would try bluetooth in your case. It could work out the same, but maybe not.
Btw, your basis 1000us is something which happens to more people, and I had that myself with Vista and never could get rid of it. After upgrading to W7 it was gone (oh, you 've probably read that from a few posts back).

Yes, I'm afraid this is a commonly known issue, and applying to IR keyboards as well. Interesting. I have the logitech cordless desktop, the most basic one, and I dont experience any difference in the latency pattern when just moving the mouse or using the keyboard (the latter is very rare). Nor when giving commands with IRTrans/Girder. I believe that is the cr*ppy logitech software. Since long time (once it caused soo many problems in an otherwise excellent system), i never install it. So i would sugges to uninstall the logitech software and use the built-in windows drivers. This means no extra keys, sorry. |

Hi chaps just getting back into XXhighend... ...and I spent about a day using Windows Performance Analyzer (WPA is a powerful set of programs that provide detailed views of system and application behavior and resource usage.) Long story short, I couldn't find any "one" thing that was giving all the latency in Vista (the 1000us spikes). I came to the conclusion that it was many things happening at close to the same time? So until someone with more know-how sets me right I'm happy to live with the latency. However, I am just about to build a dedicated windows 7-64 machine for XXHighend (my vista machine set off with this intent but funny how it became my video/photo/card making PC as well?) |

Old topic, but I finally saw an occasional dpc reading of 1us today. My average dpc readings are around 2 to 2.5us after the system settles. I don't know if dpc directly tests the audio data flows of XX but I agree with comments about general sound quality improvements as the dpc's reported latency improves. Aggressiveness has reduced and naturalness of sound presentation has become markedly better, particularly as the last few micro seconds have come out of the dpc readings.
The system is a dedicated Audio build with everything cut that I can think of or have read about. Windows Explorer has also been killed which is how I normally play music.
Nick.

Hi Nick - Thanks for sharing.  I only noticed the similarity with my system ... I mean, I traded my AudioNote for something else allright, but a GainClone into horns ... Couldn't you find anything better for your horns ? (I can't, so far  ). Peter |

Hi Peter Still I was running a pair of Audio Note P4s. I loved the 300b midrange, but could never get the extension in the highs and lows I wanted, despite LOTS of modification. Then I tried a basic commercial LM3875 chip amp design and was amazed by the sound. The amp config I built has Stevens and Billington silver wired TVCs for volume control and two LM3875s per channel (Peter Danial kits) driving the mid and high range drivers of my Duos. I also went for 300VA R-Core transformers and Black Gate power supply caps. I don’t need much power and the gain clones have real tube like immediacy but also deliver base extension and smooth top end. They are almost too simple to drive such expensive speakers but I really enjoy the results. What amps do you use ? gainclones ?? Nick |
