OWNER'S MANUAL

Please study this document carefully before using equipment

RoHS

CONGRATULATIONS!

You have purchased the world's finest preamplifier and certainly one of the
most unique. It has seen over seventeen years of development and represents a
level of performance that others will be struggling to achieve for years to
come if for no other reason than we control the patents. At the time of this
writing, it is the only fully balanced differential all-vacuum tube design in
the world that also supports the 600 ohm standard.

Every part of the preamplifier has been extensively tested and engineered so
the product will perform flawlessly for years to come, with little if any
service.

Please read the manual carefully and follow the instructions closely. If you
have any questions, do not hesitate to contact your dealer and always feel
free to contact us at ATMA-SPHERE MUSIC SYSTEMS. Here's to many years of
happy listening!

Sincerely,

Ralph Karsten
