Components are often discussed in isolation. Yet some systems sound special together, while others are competent and yet others are, well, not worth the effort. Here is a system that I put together and find to have a sound quality far exceeding the system price point. This will be traveling with me to many meets for the foreseeable future. Components: All prices in US Dollars. To my ears this system delivers dimension, depth, emotional connection that help suspend hearing the system and focus on connecting with the music, very similar to how I experience it at shows. System notes: Gungnir MB - an extraordinary DAC with exceedingly low jitter, excellent channel matching and gain linearity among its outstanding performanc - a must hear DAC. Project Sunrise III - hybrid tube - mosfet OTL with no negative feedback - very low residual noise, highly configurable - tube is employed at what is does best, voltage gain, mosfet employed at what it does best, current gain. HD650 - Sennheiser must have been sneaking in design changes over the years. Current production appears to have beneifited from HD800 design innovations and sound much better than HD650 from years ago. Linear Power Supply - reduces further the already low noise noise floor on the PS-III Regen USB - cleans up USB crap from computers Canare L-4E6S starquad cables with Neutrik connectors - used at many recording studios / mastering facilities around the world - technically excellent cables with high EMI noise immunity Radial Twin ISO - Jensen transformers adding a little iron to the audio path while converting DAC balanced outputs to single ended inputs for headphone amp.
