Audio Research SP-17L preamp (no phono stage), customer trade, age unknown, rated 8/10 for minor marks. Includes brand new metal remote and factory box. 30 day warranty.

New $2,995, sell for $1,690.


The SP17 brings much of the performance offered by its acclaimed and more expensive siblings to a price range that is within reach of many music lovers.

Externally, the SP17 looks virtually identical to its predecessor, the SP16, with a full-sized 19" front panel, handles, and the same display. The SP17 is completely single-ended with five sets of inputs (labeled Phono, CD, Tuner, Video and Aux), plus a Processor (unity-gain) pass-through. There are two sets of Main single-ended outputs, plus a Tape (monitor) out. There is a 12-Volt trigger, full remote control, and a removable 15A IEC power cord.

Internally, much has been improved. The SP17 features low-noise JFET inputs in both the line- and phono-stages, and instead of 12AX7s you will find a 6H30 in each section – all of our preamplifiers now employ this high performance long-life tube. The same high-voltage regulator found in the LS17 and LS26 is now utilized in the SP17, and so is the same 103-step volume control – the SP16's control had only 70 steps; adjustment of the volume is much finer now, which is especially useful at low volume settings. The maximum input is 9 volts RMS, versus a maximum of only 3.5 volts RMS before overload in the SP16. The SP17 features direct access codes and discrete On-Off commands for power and mute functions for incorporation in a system with a master controller. And, like all of their other preamplifiers, the SP17 is pure Class-A. The line-only SP17L is also available without the phono stage installed.

Bandwidth has increased, with -3dB points below 0.3Hz to above 120KHz. Output impedance has been lowered, improving the SP17's ability to drive long cables and low impedance amplifiers. Gain in the line section has been reduced very slightly, from 11.5 to 11.1dB, but it has been increased in the phono section from 43.5dB to 47dB. The SP17 is 2dB quieter in its line section.

What do all of these changes translate to musically? Greater articulation, better image focus and an apparent speed resulting from lower distortion and a lack of smearing. Bass definition and control are improved, and dynamics simply pop. And because it is so quiet, the music stands out in bold relief against a black background. Individually, each of these attributes is easily identified and meaningful, but combining them in the SP17 provides one with the same type of magic offered by their costlier line-stages.
