It's best if you can audition HD800, T1, LCD3, LCDX. HE-6, SR-009 before spend that kind of money.
I have auditioned T1/HD800/LCD3 with MJOLNIR, HD800 with liquid glass, and SR-009 with BHSE in a meet.
If you liked your Stax rig, the SR-009 is probably your pick. The SR-009/BHSE combo is the most transparent and detailed rig I have even heard. HD800 is a good potential candidate if you can get the synergy right. The last I would recommend is the LCD3(not sure about the LCDX since I haven't audition it). The LCD3's soundstage and instrument layering is too lacking when compared with eletrostats. Bass character is another different story.
I understand the SR-009 and BHSE rig is currently very out of reach. But you might want to get a good source, SR-009, and a lower end stax amp first. Upgrade to BHSE when you have the funds.
Another way you might want to go is get the HE-6 and Cavalli Liquid Gold ($3950, it's on sale on cavalli audio's website). This way you will still have money to get an awesome DAC.
I'm using Wyred4sound DAC-2 as my DAC and I personally don't think buying any $3000+ DAC is a good investment. The digital technology in audio is improving so fast. A $3000 DAC might be outperformed by a $2000 DAC next year.
