Was wondering which headphone should be my next upgrade. I am using the Schiit Bifrost Uber with USB and Schiit Lyr but I am still tube rolling with these tubes but I am mostly using the Mastush*ta 6922 tubes. I love a wide and spacious soundstage and deep, tight, fast and textured bass with long decay. I don't know which to go for. The store I am most likely to buy from is HeadAmp and the HD800 is cheaper there by $500 compared to the LCD3. Which should I buy?
