Little background : I'll try to keep it brief, I've been getting back into audio more heavily & focusing on headphones, not a full-size rig like my previous system. I bought a pair of DT880s, "600Ohm" off of eBay a few months back, and an Objective 2 from a member here.
Wow, great bass, awesome clarity, overall huge improvement from my last loudspeaker system.
I get the tube itch, and buy a Bottlehead Crack assembled from a member. Whoa....
The Problem! Big time channel imbalance with the Crack! Left is way louder. I measure everything, spend 5 hours debugging the Crack. DT880s still sound balanced on the O2..hmm...
Then I finally ohm out the DT880s: 578 ohms on the right to 47 ohms on the left channel measured at the connector.
How can this be??? Really poorly matched 600 & 32 ohm drivers swapped in by the previous owner?
I haven't opened them up yet...the channels sounded the same on the O2. Maybe I have a tin ear!
Should I be calling Beyer up right now and ordering a driver? (and trying to get $$$ back from my eBay seller...)
