You could probably find a used McCormack DNA 0.5 Rev. A on the used market for less than $1500(and pay no tax) now that his new amps are available(saw one on this site for $1400 recently). This amp is considered to be one of the best amps at any price and is still better than his new DNA-125 as that amp incorporates approximately up to Rev. B specs. My Rev. A totally opens up my system and creates a crystal clear window on the performance--don't want to listen without it. Just another option. Best of luck.
