Description :
The Counterpoint SA-5000 was introduced in 1990 and was the most expensive of
the "thousand-series" preamplifiers. It features hybrid video buffer/tube
phono stage and line stage. It can accept MM or MC cartridges; as manufactured,
MC stepup stage is solid-state. The circuit board in the Counterpoint SA-5000
employs a floating subchassis for mechanical isolation. The unit has two 6DJ8
tubes in the phono stage and dual 6DJ8s in the line stage. As with all Counterpoint
preamplifiers, there are two gain stages in the phono section with passive RIAA
equalization. The line stage is a single stage and there is no loop feedback.
All tube stages are followed with solid-state video buffers, two per channel
in the phono stage and one per channel in the line stage. The phono stage can
be configured as a JFET/tube cascode for MC cartridges, or a simple tube stage
for MM cartridges. Vacuum-tube power supply voltage regulator uses tw0 6DJ8/6922
type tubes and one 12AX7 for regulation and one 6CA4 for rectification (located
in external power supply). The inputs include five line-level inputs plus tape
in, and outputs include dual pairs of tape outs and main outs. Other functions
include MM Loading, Tape Send Disable, Main Output Select, Gain Trimmers, Polarity
Invert, Output Level, Mono, Volume, Mute and Power controls.
The Counterpoint
SA-5000 preamplifier
has such powerful dynamics that it can smoothly transit between passages of
very different tones of the music effortlessly. It is also very silent in little
spaces between the notes where it counts. The Counterpoint SA-5000 creates such
a realistic soundstage that it seems completely "divorced" from the
speakers. The imaging is breathtaking, and turns the room into a stage where
all the performers are in the same room. Each of them are in their own individual
spaces. The Counterpoint SA-5000 is not of the super-etched type. It is just
very natural, much like a real concert. Just sit back, relax and enjoy the music.
