I recently found after recommissioning my old DT-770s that hair had actually found its way all the way into the back of the driver. I had to completely disassemble the right side by removing some of the glue, carefully pulling out the driver, and even more carefully removing two small strands of...

I suppose the next logical question before I order the Elpac power supply is whether the improvement is worth the cost or if it's just something that's nice to have. I'm also using AD700's and might even get my DT-770's fixed one of these days.   Thanks for the link and all the help...

Mine came in the mail yesterday with a Tangya 12v, 2a power supply that has an input voltage of 180-220v. First thing I did was go to Radio Shack looking for the 15v power supply but all they had was a 12v, 1.5a model for like $27. So...I figured what the hell and tried the included Tangya power...

Well I ordered the MK2 SE, not sure if it comes with a power supply or not.   At any rate can someone recommend me a decent one?

Anyone know what the difference between the MK2 and MK2 SE is? All I can see is the non-SE version comes with a power adapter, which I read wasn't very good anyway.   I'm about to order one and would like to know which one to get and whether I should get a different power supply.

Low frequency distortion, most pronounced by light, punchy bass is the best I can describe it.

I guess it had never occurred to me that it might be the cable. How would I test to see whether it's the cable or driver that has gone bad?

Two years ago the drivers on my 770s went wonky and rather than fixing them I packed them in the box and let them collect dust. My other cans just bit the dust and I'm wondering if it might be worth it to send the 770s back to to Beyerdynamic for repair. I'm curious if anyone has had experience...

Next thing you know this guy will be arguing that hard drive rotational speed and platter density has some kind of effect on digital audio. I read perpendicular recording is **** for hi-fi!

Heh, well i'm not too hairy but yeah there was some hair lodged in the foam cover. I took out the snap ring and cleaned off the foam really well and also inspected the white cloth that covers the driver. I'll try dusting it out with some compressed air as well I suppose and getting a shorter...

Hmmm, so about 6 weeks ago (early January) my first pair of DT770's (80 ohm) started getting some distortion on the low end in the right hand driver after ~800 hours of use. I cleaned every spec of debris from them and tried two amps but clearly the driver was going bad. The dealer I bought them...

I know this thread is for the LD2++, but I was wondering if someone could give me advice on replacement tubes for my standard LD2. The stock tubes have 1000+ hours on them and are not looking so hot...I have no idea what the life expectancy of a tube is or what to look for in a bad tube so any...
