On the other hand, Class-A tranny amps and valve amps need a period of warm-up to let the quiescent current/temperature stabilise. I HAVE heard caps get worse during burn in. Specifically VitaminQ paper in oil high voltage caps will sound pretty good when first installed, but after 10 hours of running music they sound abysmal, harsh, grungy, very yucky sound. After another 15 hours or so they start getting better and by about 30 hours are about where they started. Between 30 and 50 hours they improve some more and sound better than they did originally. Every VitaminQ I have ever used goes through this process. Other brands of paper in oil caps go through something similar but with a different time table. Some take only 5 hours to sound awful. Plastic film caps (polypropelyne, polystyrene, polyester) don't have this wild behavior. I have heard some improve somewhat over time, but not nearly like the paper in oil. Transformers also definitely burn in. Something about the magnetic properties of the core changing while the domains realign themselves constantly for the first several hours of use. How much and how long it takes is very dependent on the core material used. Nickel behaves very differently than steel in this regard, and cobalt yet again quite different. There is another completely different effect which is warm up. This happens every time the device is turned on. Most electronic components DO change there electrical properties with temperature. Even digital audio can be affected by this. I have looked into this extensively and found at least two methods by how temperature changes can effect digital audio. First is the resistance of the transistors inside the digital circuits. Cold FETS have a lower resistance than hot FETS. This causes the circuits to switch faster which means the switching currents induce greater voltage drops/bounce on the power traces inside chips and even in the ground planes on boards. This is not fiction, its actually quite easy so see. Unless extraordinary measures are taken this noise WILL affect clock circuits and even analog circuits. Its especially noticeable in some DAC chips. They sound much better as they warm up. I did an experiment where I took a cheap DVD player and glued a resistor to the top of the DAC chip and fed it DC current to warm up the chip. I also added a thermocouple to the chip to take its temperature. I could radically change the sound of that DVD player by warming up the DAC chip. It sounded much better as it got hot. Of course at some point it stopped working altogether, so it CAN be over done! This might be one of the reasons I like DAC chips that get fairly warm in operation. BTW some DAC chips are very sensitive to temperature and others not nearly as much. The other method is in oscillators themselves. Many crystal oscillators actually have lower jitter when they are warm. Crystal ovens are not JUST for stabilizing the frequency. In my own designs I like to use oscillators that get fairly warm, the jitter is lower than cool running ones. These effects are actually exhibited in the Touch, but since the temperature doesn't rise by a lot between cold and on for a long time the difference is not very great. I've seen DVD players that have powerful DSP chips that get VERY hot exhibit these effects to a large degree. I did not notice any burn in effects in the Touch, but I CAN hear warm up effects, but its not very much. I suppose I should try the resistor on the DAC chip test on the Touch and see what happens.

Re: [SlimDevices: Touch] Touch and burn in
Hi Gazjam, Currently switching between analogue and digital (coaxial), via a QED Digit/Positron DAC, trying to tell which is best. Analogue more enjoyable, via the DAC more information! The analogue outputs are very good, there is always room for improvement but will I be able to hear it? I'm really enjoying listening to mine but may have to think about mods to the QED Digit or look for an alternative. The TeddyPSU (in my opinion) was a must have for the SB3, on the Touch it make only a very slight difference to the bass notes, perhaps slightly clearer and goes lower but my speakers are not really bass monsters and excel in midrange.The SB3 PSU was a right sack of Cr and flooded the mains with noise and replacing it made a huge improvement. I may move the TeddPSU to the bedroom SB3/NVA AP10 system. An improvement for the Touch but is it £200 worth? I think the B'Dac issue is with the NVA pre/power amps passing through and amplifying anything thats fed into it rater than being filtered like a conventional amp. -- shevans SB Touch, TeddySB3 (PSU), QED Digit Positron PSU, NVA P90sa passive pre-amp, NVA A40 monoblock's, Fostex FE206E based big purple people eaters!

Re: [SlimDevices: Touch] Touch and burn in
Phil - some people believe cables burn-in :) Maybe if you apply upwards of 10kV and several 100s of amps you might see a change to a cable. So trying to straighten someone out of the thought that burn-in of a digital device like the Touch is a myth is a long road if they think their copper changes the way it sounds by apply a few volts to it. Heck is far as they are concerned what happens inside the Touch is nothing short of a freakin miracle. I think the burn-in myth probably started with speakers where burn-in actually does have some merit since you are talking about a device that has an elastic component that does change a good bit depending on the make as it is used.

Re: [SlimDevices: Touch] Touch and burn in
I've certainly heard changes in things like new coupling caps in my valve amps,and no I didn't imagine it,because they can sound bass heavy one day,and very toppy the next while they break in.I can't say I noticed any change in the Touch though.Sounded great straight out of the box.Wonder how long they are run for in the factory? -- Ali Tait Ali Tait's Profile: http://forums.slimdevices.com/member.php?userid=37387 View this thread: http://forums.slimdevices.com/showthread.php?t=77727 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Touch and burn in
I can imagine some sort of burn in for speakers when they are new since they have some moving parts. I can imagine letting your equipment warm to the operating temperature might make some difference. Maybe 5 minutes. I can also imagine letting electronics run for a few days when you get them might held you uncover any defects in manufacturing quicker since things typically fail in the first few days. -- pounce pounce's Profile: http://forums.slimdevices.com/member.php?userid=12645 View this thread: http://forums.slimdevices.com/showthread.php?t=77727 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
