The Stellia, first of all, though maybe not everyone's cup of tea color wise, is an absolutely beautiful headphone. The design and materials are of the highest quality of any headphone I have seen and the packaging is top flight. It took about 40 hours of burn in for the beryllium drivers to open up, at which point the sound became very dynamic top to bottom, with all the detail your source can provide, presented in a very natural timbre. While not the widest soundstage, it does a wonderful job of instrument placement and with it's stellar resolution, it never leaves me feeling that it is too intimate and closed. Bass is tight, with plenty of quality sub bass, mids are natural and well balanced, and the upper registers are so very clear and never harsh. Best of all, it is extremely easy to drive. If you have a high quality DAP, that is all you need to enjoy the full dynamics and resolution of the Stellia. All in all, if you are looking for a closed back headphone of high end audiophile quality, Stellia is definitely a set to look at!
