first sound paramount mk ii upgrade

...for those of you who own this wonderful preamp, mr. go has an upgrade called 'series iii '. having just received my unit back mid last week i can assure those of you who are thinking about doing this that it is worth every penny of the $1200 it costs to do the upgrade...i am burning in the unit with continuous play now x 6 days and the improvement over the unit's former sonics is not subtle at all but amazing......give him a call / mail and find out about won't be sorry
