Jawed, I agree with you that there are changes in the body due to different conditions of fatigue or other. For example when I am very tired I feel less basses ... but this is a condition that I know well. Regarding to the two or three hours I made many tests, in different physical situations...

Jawed, I do not speak of a continuous listening of two or three hours but the difference if I listen in the first half hour and then I stop and resume after this interval. The difference is clear in my memory. Sibilance decrease, the sound is more liquid (less distortion ?...) and also the image...

Again about sibilance and the 800C... are you sure that the fault is all its own ? I noticed for example that changing the power chord of the amplifier with a better one reduces this effect and also, with the Violectric 281 after about two hours, preferably three, they are greatly reduced. It...

I don't know your experience but I thought that my 281 was burned-in at 100 hours, but now, when it has approximately 200 hours of life I realized that it is again changed... more rich midrange and more warmth...

just a little note about the judgment on the hissing of the old 800: the first 20 minutes would be better not to listen… after the situation improves, but after about two hours the effect of sibilance is greatly reduced, if not eliminated in less severe cases. I understand that not always we...

Shabta, as you can see in Anaxilus mod thread I tried with Velcro and it seems to me a good compromise. Also it should be a fairly standard material from nation to nation...

I have experimented with Velcro, thinking to try a material that breaks the waves rather than absorbing (I don't know if it is a right thinking...). I used to height 5 cm. and the softer part. Not finding larger I cut into two halves. I made this change by only a few days (so I need more time...

After about three years with my Hd-800 I don’t think that at Sennheiser they made the mistake to built an headphone with an exagerate curve in some regions… Better I think they made an headphone for very close to perfection recordings and for very very good electronics; in few words the fault...

I have read with great interest this discussion, also for my situation. I own a HD-800 and a Phonitor (first model) with a Bel Canto CD2 and Dac 2.5 as source. I am very happy with the result but there is still something to improve. The overall sound is satisfactory but still with some traces...

I apologize if by chance the information has already been given and I have not seen it but... with the Apple Camera Kit it's possible to connect the x3 and use it as a DAC for the ipad ?

I would like to have your kind advices...   I own a Bel Canto CD2 and I wish to upgrade with a DAC of the same brand. I am looking for a used DAC3 and a few days ago I called a store that sell them and talking about the matter with the seller he exposed me this theory: model 2 and model 3 are...

On my Mac (10.9) all goes fine.  I need to go to "system preference > sound" and enable the out with X3 name. Again may be that in software it needs another setting

First of all, since this is my first post, I have to thank all those that have been very helpful for me when I was looking for some informations ! Going back for a moment to the issue of sound changes with the new firmware I also noticed something. I'm pretty sure and I don't think to a placebo...
