After quite a bit of study, I decided against both the D12 and Leckerton. I ended up getting a Sunrise Project II tube headphone amp. I initially used the DAC from my D10 with it and recently replaced that with a Musical Fidelity V-DAC. The V-DAC is not a great improvement but the Sunrise II is phenomenal. It is more than I could have hoped for in an amp. At $244 built, or $199 in kit form this tube headamp is one of the best buys in audio.
