I have a pair of Sennheiser HD600s. I recall finding them muffled sounding and lacking high end extension when new. Dozens and dozens of hours later and a cable upgrade (to Senn 700 or 800 cable?) they sound much better. Have to say though, they don’t have the sparkle of the AKG550s but then the AKGs are light on bass compared to the Senns. After time for break in, consider a Schiit Loki for equalization if things don’t improve to your total satisfaction.
SQ lacking
I bought my first hi end audio system. Played, so far, some Redbook cds. On my speakers, I think I am hearing improvement as some time goes on. My room is horrible for room acoustics...as bad as it gets...so I am going to address that with my Dspeaker antimode 2.0 soon.
But then I switched to my headphone unit, of which I have a Questyle CMA 600i headphone amp/dac. So room acoustics have no import here. I plugged in my Sennheiser hd6xx headphones, popped in some Redbook cds, and man it just sounds rather muffled to me. I don't hear crisp details and nice separation of instruments. I am not wowed. I have a good system here, every component getting good reviews. So, does it need break in? Is it terrible cd recordings? Or, would I realize better sound if I went cd transport - dac - headphone amp? Right now it's cd transport - dac - preamp - headphone amp.
