Nice, I wish my environment was more noise free so I wouldn't have needed to deal with it, but it's something that will vary from one environment to another - which of course can change if you move - from one room to another or plug in to another power feed, or add noisy equipment, or move it all to another location.Yes, that's the guy. Great workmanship.
I do have to say that I didn't experience any "noise" issues using my A90/D90 from the RCA connection. It is dead silent. I was all prepared to buy the cables that you recommended but don't need to. This combination is pure magic with my D7000.
So it's good to keep in mind what will work to solve noise issues should they appear some day.

Ahh, yes a return to the seller often becomes a swap for a new unit - much easier with less delay.I am hoping that Thomann (the retailer that I returned them to), just does a replacement. If they send them to Beyer that could be several weeks. I am hoping, with fingers crossed, that they send me out a new pair this week.
Honestly, with the tube amp and the Violectric amp I see no need for the balanced upgrade. My Liquid Platinum has oodles of power due to all the gain, but I don't feel that I need it at this point.
There are a number of amps now that have Balanced outputs with higher power delivery than the included single-ended outputs, so in my case playing music on my amps would benefit from driving balanced fed headphones.
If your AMPs already put out "enough" power to drive 600 ohm headphones on their 3.5mm / 6.3mm ports, then you've got no particular reason to modify your headphone's cabling to balanced.

Beyerdynamic is either slowing down manufacturing or ending production on these DT 880 600 ohm models - DT 990 600 ohm too, because I had a difficult time finding them available as new production, and the specific special editions I was interested in were nowhere to be found as new - I had to buy "used".
Fortunately the DT 880/990 600 ohm units I bought used seem hardly used - their condition is like new - with the DT 990 600 ohm sounding like it has more hours on it than the DT 880 600 ohm - which seems like it has no play hours on it at all.
The new versions of Beyerdynamic T1 / T5 are 32 ohm only - at least right now - perhaps Beyerdynamic is phasing out building new 600 ohm coils for new headphones?
