Do I need a DAC - Page 2

post #16 of 23
I agree. Something is not making sense here. :-)

I have not gone back to the set up with out the DAC, but when I get the time I will. I thought too I was looking for something that wasn't there so last night I tried the DT's again. At first they sounded fine then I went to Foobar  and played some stuff and discovered that I have a vibration or warble sound in the bass area with the DT's. I switched to the M50's and all is fine. I'm probably not describing what I'm hearing very well but I can tell you that it's not clear crisp music. I went back to Spotify with both sets of cans and discovered that on some songs the DT's were fine and on others it was not. As I'm writing this I went back to listen again to the DT's and they sound fine, just different. It seems that if I turn up the volume while I'm listening to the Rolling Stones, Emotional Rescue I loose the crispness that I have at lower volumes. I turned down the volume (to a much more enjoyable level) listening to Wild Horses and they sounded great. However near the end of the song around the 5 min mark I heard it again. I tired a pair of Q701's to see if it's the same, it's not; the 701's went through that area just fine. It is in the recording though. It's just the DT's either show a flaw in the recording or don't handle that freq. very well. 


Thanks all for the info and help.


I have a new pair of HE400's coming soon, I'll see if I can hear the same thing with those. I might be getting caught up in the technology and getting away from what cans do, listening to music in a different light.

Like I said, this has happened to me. I even had others listen. They could not hear my perceived problem. I thought they just could not hear as well as I could. I had to listen carefully before the problem became apparently obvious to me. Then some time in the future, I listened to the same music. I thought the music sounded great. So I thought I must had been going crazy. :-)

In my reply window there are 2 lines at the top of the window that allow you to mod your text. I'm using explorer to access Head-Fi.

This is what I discovered. Over the weekend I was experiencing some issues with my wireless mouse on my HP tower. When I moved the cable slightly away from the JDS ODAC the mouse worked better.  This was a pain as I use the phones when I'm on the net. I then got out the wired mouse and connected it to a usb port on the back of the tower (ODAC cable is connected in the front), the mouse worked great. I then discovered the (maybe imagined issue) I had with the DT990 phones disappeared. I know this sounds nutty, but all I can say is that now the DT990's sound as they did when I first listened to them; prior to the ODAC. Clear, smooth up and down the spectrum with just enough bass. They now moved back to the top of the list as phones I use.  I know this all sounds goofy, but this is where I'm at.

Was there any tequila involved in all this switching around? tongue.gif

It was you peeking in my window, YES, there was some tequila involved; Patron Silver to be exact. On Sunday just prior to the SuperBowl I switched to Makers Mark and the Phones sounded the same. I'm golden now; later this week I'll try some Belvedere Vodka. If it works I've got all my favs covered.

only problem is when you wake up you won't remember which phones you liked best :) oh well, just have to try all over again next weekend!
