LT1364 will burn my finger too. I'm testing LT1361 now and its not hot.

My Zero arrived few days ago and i'm amazed  , this is my first headphone dac / amp combo. I can say it's a big improvement from an M-audio sonica theater external soundcard. I didn't wait for the stock opamp to burn in, its has been swapped with 1469 in DAC and 1361 in headphone amp section. It is too early to have an clear opinion, they have only few hours of playing. Btw as first impresion of this combination I can say I like the bass definision and extension, the highs aren't harsh at all.
I have a pair of SR60 and I can say they really like Zero  Soon it will arrive my SR225 and I think there will be more fun. I also have an AkG k601 ,obvious better than SR60, very detalied headphone with a great sound stage but I consider to be not as much involving as Grados.
There is problem if my coaxial Led is clipping, or sometimes goes off?

I just can't seem to get the sound to be all that. My previous best combination was LME49720(dac) + LT1469(amp), but I sensed a very slight warm coloration in the mids and a small flowing effect which devoured a lot of the air (the flowing effect(made the music "flow" effortless) was very pleasant, but the slight air lost made it very hard to breath), so in the end I couldn't stand it and had to change.
The stock does a lot of things right, but I want a little bit more detail, but the coloration, or UNcoloration is very good, as is the air.
My favorite (for the moment) favorite combination is LT1469(dac)+LME49720(amp) and it sounds very good, but I think I hear the slight midrange coloration of the LT1469 shine through.
It might be that in the end, beyers, grados/alessandros, or me in general just don't love the LT sound, so I might have to turn to OPA627 or similar.
Any suggestions?
|
I'm not dissing you, or coming down on you by saying this, but I think saying it, may help others as well. "Don't be too analytical, enjoy the music for a while".  It is so easy to get caught up in the rolling, and never be totally satisfied, when many of the combinations you have found, would easily do the trick.
I also would suggest the OPA627's in combination with the LT's. When I was judging both outputs, one of my favorites was the OPA627s in the DAC, LT1469s in the headphone amp. It might be worth a listen.

opamp rolling next!! |
There has to be something to the changes in sound cards, even when they are serving as transports. The difference in sound between my notebook optical out and desktop optical out, is very noticeable. Almost exactly what you said.

I'm glad things are going well! Good combinations you are trying too. I would check and see if you have a loose connection on the LED board up front. After shipping, anything is possible.

It is worth mentioning that the connection on the LED board is soldered. I already tried to detached it. 
Check the cable and the plug to the main board...

Like having a bunch of Tungsol black glass 6SN7's all in a row. They are great but it is nice to mix it up. I think you get a better texture and excitement to the music but who knows until you try it, right?

Boy, that seems out there. So do you think they really design the opamps to sound a certain way and then number accordingly? Or is it the numbers that either doom or elevate the opamp? AD8397, a little unrefined on the top and slightly bright. So what are the numbers saying there?

Ok, then how do you define the theory of chaos with numbers that will form a pattern? Or does it matter? Or is the chaos the interacting numbers of an undefined sequence?

And there is nothing to thought of anew, only rediscovered for all possibilities already exist but are to be found and deciphered.
