Audio Research LS-17 SE

For Sale
is the Audio Research LS 17SE line stage. I am selling due to upgrading to a Ref 5. The unit was purchased from Audio Salon on Audiogon about 1 year ago.  The line stage is
in excellent cosmetic and working condition with original box, packaging and all included
accessories.  Sales only to US lower 48 state locations.



Description:  The LS17 SE preamplifier benefits from a long
tradition of exceptional preamplifier technology from Audio Research and shares
many common traits with its larger peers.  The
SE treatment of the Reference 5 SE preamplifier and Reference Phono 2 SE phono
preamplifier have been applied to the LS17 SE to great success. Internally the LS17 SE
builds on the architecture of the LS17 and adds SE upgrades to provide
exceptional performance. New Teflon coupling capacitors and other performance
enhancements combine to create a preamplifier offering greater detail, spatial
cues and dynamic breadth. Two 6H30 twin triodes are at the heart of the Class A
audio circuit. A custom designed power transformer provides serious current
delivery. In concert, the components of the LS17 SE create a sound that will
truly delight the listener – this is a preamplifier dedicated to delivering a
great musical experience. The LS17 SE has seven inputs (including the processor
input), two of which are balanced. There are four outputs, record and main
output 1 (both single-ended) and two balanced outputs. There is also a 12 volt
trigger for controlling the power of other system components. The A.C. power
input is a 15A connection.
