I had the Questyle CMA400i, nice all in one solution for low to middle impedance headphones. Than brought the RME Adi-2 DAC and paired it with the Singxer SA1. Pretty awesome combo for planars, but I had no use for all the fearures the RME is offering, so I searched for a more puristic Class A solution. Ergo Burson Soloist. Got it used in a bundle with the composer just yesterday. To be honest it's a bit overpowered for the Elite. Using it single ended on low gain to avoid the noisefloor in midium/high gain but have to crank it atleast up to 75. So probably not the best solution for the Elite, although it sounds awesome. Appears a bit wider and clearer than RME/SA1, but must do more a/b testing. Getting a balanced cable soon, so I hope that makes a difference.
