Hello, Abstract, and welcome!
We are more active on the Facebook group Gateway Audio Society, but there's a lot of interested people here
I am primarily a speaker guy, but I have gotten to hear HD800s a few times, and thoroughly enjoyed them.
I have 600s, and mix in HD280s because I require isolation and even balance to have a chance at succeeding-I mix most of the live music that goes out on Channel 4 (KMOV).
I can say that if I cared about having headphones at home, HD800s would be high on my list of wants, along with nicer Stax electrostatics. The brief time I've spent in SR-009s are wonderful. Sadly, there's not a lot of places to hear headphones in Saint Louis. There were a couple of Head-Fi meetups in the distant past, and I haven't heard anything about any recently. I have a few pars of low end Sonys, and like the MDR-V600 the best out of my hodgepodge of MDR-V7506, 7509, and V6s. I enjoyed the Sennheiser HD650s I have had twice, but sold them each time due to non-use. The HD650s sound better than the HD600s, but the 600s are just plain accurate, and for a headphone, that's what I need, so I kept the 600s. The 650s are also more sensitive. I feed headphones with either a Lynx Hilo, Benchmark DAC3HGC, or Mytek 8X192ADDA.
