I've made several changes over the past year and streamlined the system. Addition of the subs and a new cartridge phono stage have made the biggest difference. Future upgrades at the top of my list are; a bit perfect upgrade to my DAC and better music streamer. Thanks for looking!
This is a late response but... The HD-650 withe the tube amp (Darkvoice 337se) was really great to sink into a couch to. I ended up selling the amp though (I'll never part with the headphones). I also love the LCD-2/Schiit combo, the low-end is incredible and it is far from "clinical" despite being very detailed. In the end it is less finicky, more detailed and just as much fun.
@dusty, it isn't ideal but moving the speakers up helped with that a lot. The Cylindrical Diaphragm tweeters on the Gallos image quite well so I think they offset some of the negatives. I'm having a hard time selling the wife on thick curtains or acoustic treatments on an indoor window (;
