The sound of this Soloist headphone amp is simply spectacular. I heard with (Sennheiser HD800) much more details, transparency from the very first time I listened to my Soloist head amp. The burning-in period gave clearly positive effect: the sound of the Sennheiser HD800 became even more balanced. Soloist was a great upgrade from the Lehmann Rhinelander headphone amplifier.
