The Official Beyerdynamic T1 Impressions and Discussion Thread

Actually, I believe optical/coax carries up to 24-bit/192khz of uncompressed PCM in 2 channel, therefore you get the full benefit of lossless DTS HD Master Audio & Dolby True HD when the 5.1 audio track is downmixed to two channels. Feed that to a good DAC & HP amp and your T1 will provide you with an outstanding 2 channel listening experience!

So defeat the entire purpose of the Headzone so he can see "the full benefit" of lossless 2 channel audio? We're trying to emulate surround here.

  my two cents: I'm not talking about sound signature of Soloist ot tubes or what ... if we talk about power, OTL & High impedance is not "legend". It's "electricity", "physics" or something that someone can calculate.
 
T1 has needs enough Voltage and mW as you can see in innerfidelity resources.
 
If the soloist is 4W at 16 Ohm and 1W at 30, how is at T1's impedance, I don't think it will be enough on 600 Ohm and 1400 Ohm peak. If the T1 becomes harsh, screaming or distorting, it's not T1's fault, neither Soloist quality fault. It's electrical pairing.

 
Please provide a scientific explanation why Corda Classic powers these phones so well.

I cant answer your question there RedBull, however I have read many threads praising the T1.
All I can say is, I find the DT 770 very comfortable, any time I go to watch any sort of TV/Film, I always use the 770, they are lovely.
I did find them fairly bulky at first yes, but the comfort is fantastic. I have got used to there size, and now it doesnt bother me in the slightest.
The T1 can only improve on the sound and quality over my 770s, I would imagine.
 
My only issue is, and I am not sure if this is personal to me, and its quite strange issue. I find I get itchy ears sometimes (I dont think its to do with warmth), I think its something to do with the vibration and my ear wax lol.

There can be! or may be not. I will try to give, but I'm not sure.  In my opinion neither Hempel's or Solmon's models fit this question, but I'm not sure and I will try. May be Van Fraassen's one should work, but I think it will put it in a too subjective way, rylean one can do it, but it will put in an operative linguistic way. And we have't enough data to go on.
 
In the orthodox way of treating a Scientific Explanation, (Hempel's 1968 and later papers if I remember correctly):
The explanandum "Corda Classic powers these phones so well" could be explicated if Corda classic output is sufficient  to reach the minimal requirement of 0.346 Vrms at Impedance @ 1kHz at 665 Ohms. Giving the status of actual physical laws known.
I this case we can have a scientific explanation under Hempel's nomological-deductive model which can be as
 
explanans:
 
Initial conditions:
(C2) Output power of the amp: X at 665 Ohm when plugged to a Y Db sensitivity Headphone
(C2) "Well sounding" means low distortion THD under Z and things like that.
(C3) T1 is a well sounding phone and not distorting at Z if rightly powered (C2)
(C4) X at 665 and 1400 Ohm produce THD under Z
...
       
phisical laws or statements:    
(L1) Some "scientific" laws, that is, for example that in HI-fi combo THD is under 2 or 4% or lower
(L2) 0,001 V at 600 Ohm produce clipping
(L2) Other electrical laws (Sorry my ignorance)
...
----------------------------
explanandum:
 
Corda Classic powers these phones (T1) so well
 
As you see you can have a Scientific Explanation of well sounding pair Corda+T1 if you know X,Y, (that I do not know) and we are below Z.
(minimum requirements achieved obviousely) under orthodox DN model.
 
 
I trust you when you say that sounds good paired with Corda, but, in the same way, try to trust me when I say that a well built OTL sounds good with T1.

Cut the BS. I had a HA-160D, WA2 and Corda Classic, so do not tell me to try OTL, I know how it sounds and you are just trying to tell us that there is a simple formula for making something sound great. If there was one, signle formula for that, we would not be seeing dozens of different designs and manufacturers testing various potions and having different model ranges.

Thanks for your recommendation, a lot of people recommend dt770, but my preference tells me that like open can more, that's why I am going into direction of open design. If you see my inventory, I do not have any closed back cans, well except IEM, due to isolation for outdoor use, and t50rp, although arguably that is semi open design according to the manual.

But I think I have to try dt770 one day to fullfill my curiosity since so many recommendation.
Which ohm do you prefer more?
Does 770 has more bass than t1 as it is closed back design?

ok, sorry.

For those who have both hd800 and t1, which one will you prefer for movies, and why?
Right now hd800 is my fav for movies, but I dont have t1 to compare, so, any comparisons are welcome.


I would select the T1 any day over the HD800 for movies. To me, the T1 is more comfortable and has more impact. But to be honest, you can't go wrong with either. We're comparing two flagship headphones here.

If anything, I would go with the DT880 if you want more of an idea of what the T1 is. I would never choose a closed can for movies or anything else unless leakage is an issue.

I run my T1s through the headphone jack of my denon 4308. Denon tells me it puts out 500 ohms... it sounds fine to me, and also has all the bells and whistles. Surround virtualizer, eq, online radio with a decompression mode
