Title: Warm up time Post by: GerardA on March 20, 2011, 08:51:11 pm Since my electricityconsumption is a little high I decided to power down Stereo and PC at nighttime.
So this week for my birthdayparty I started XX-Highend and the stereo at aproximately 7.30 PM and been listening all evening. Well the sound was disappointing and I really was thinking about what it could be. And how to describe this. Then my daughter asked me to skip a song at 10.45 pm and I allmost did but for the soundquality. This song was sounding really better, and after that everything sounded magnificent and we could play music for a long time after. So why this sudden change after about three hours? Does this sound familiar to anyone? I know my amps can sound a bit rough for the first 20 to 30 minutes, but not for three hours and then change like day and night. I suspect something is going on in the PC for three hours after startup, but what? Now I left the PC on and it still sounds amazingly good.

Not that I have the answer for either Yes or No, but I guess I will be making up something when knowing your answer. :) Title: Re: Warm up time Post by: GerardA on March 21, 2011, 09:56:23 pm No, I have the cheaper non-ECC as far as I know.
Title: Re: Warm up time Post by: PeterSt on March 21, 2011, 10:33:45 pm In that case my answer is a little more "far out". And quite unbelieveable. Something like :
At the first run you may be using memory which fails, but it goes unnoticed. Unbelieveable for myself, but maybe with audio it can. :nea: Title: Re: Warm up time Post by: GerardA on March 21, 2011, 11:10:34 pm Does this mean the quality of the memory is not good enough or is it a softwareproblem that you can solve?
And after three hours it's back to normal as in OK? Title: Re: Warm up time Post by: PeterSt on March 21, 2011, 11:20:23 pm No Gerard, I am sorry. 99% sure my response doesn't make sense. With ECC memory it could, but now it's a too long shot.
Which doesn't mean I don't believe (in) it - or you. Must think about this. Peter Title: Re: Warm up time Post by: crisnee on March 22, 2011, 02:49:49 am Hi Gerard,
Is it possible that some kind of electrical contamination on your audio or pc system power line might be the cause? For instance I've read that dimmer switches can play havoc with sound--I haven't tested this myself, and they're not the only devices. It could even be something outside you're domain, or house.

Maybe some program running after startup, but for three hours is a bit much. Maybe a dishwasher or the washingmachine but then I will find out! The only problem is that I don't want to wait for three hours to get good music. For now I left the PC on and it still sounds good. I will be back when I find something more....

I live in the centre of a big city and I'm an Audio enthousiast. That's a tricky combination, I can tell you. It took me years and thousands of Euro's to maximise the elimination of the bad external influences on the electrical powernet, also from outdoors (factories, heavy machineries etc) I installed coppershielded main power cables, (also in the walls), put a Highend filter before my High Fi gear (only the front-end, I wanted my main amps to connect as open as possible with the powernet) and put a special HiFi main fuse in the system. Only now, after all the efforts, I can enjoy music also during daytime (albeit that it's still a better sq during the evening and night) greetings, HW |
