Esoteric does release upgraded units, but it appears to me to be more like 3 year intervals and often trickle down upgrades based on their higher end offerings. Sometimes audio companies make "new and improved" due to shortage or non-availability of parts and chips and/or improved performance parts that were previously not available in the market. Some audio companies have longer and others shorter upgrade and new model cycles.

Has anyone seen any information on this upgraded new model from Esoteric?
