The Conrad-Johnson Premier 17LS2 is a high-end, vacuum-tube stereo line-stage preamplifier introduced around 2003 as an upgraded version of the original Premier 17LS. [1, 2]Key Design & FeaturesCircuit Design: Uses a zero-feedback, single-ended class-A triode circuit powered by four Sovtek 6922 dual-triode tubes. [1, 2]The "Series 2" Upgrades: Features ten premium 2.0µF Teflon coupling and energy-storage capacitors, high-precision Vishay laser-trimmed metal-foil resistors, and a beefed-up power supply regulator that lowers the noise floor and output impedance. [1, 2]Volume Control: Employs a microprocessor-controlled relay attenuator system rather than a standard potentiometer, isolating the audio signal path. [1, 2]Connections: Includes 5 single-ended RCA line-level inputs, 2 sets of main outputs, and 2 external processor loops (including a theater unity-gain loop for home theater integration). [1, 2, 3]Specifications: Offers 26 dB of voltage gain, a frequency range of 2 Hz to over 100 kHz, and an output impedance of under 850 ohms. [1]Audiophiles widely regard the 17LS2 as one of the finest preamplifiers Conrad-Johnson ever built, praised for its exceptional spatial resolution, microdynamic nuance, and natural midrange warmth. Includes manual and remote and will be double boxed and shipped in original factory carton. Can be picked up and demonstrated in Dennis Port MA. Shipping is $130
Are you looking at the correct Premier 8 variant, and is its tube history documented? At US$3,000, this is above the four-listing median of US$2,620 and also exceeds the 75th-percentile figure of US$2,772, so the asking price is ambitious rather than a bargain. It needs strong provenance or recent servicing to justify the premium.
That said, a healthy Premier 8 remains a serious high-power tube monoblock, valued for combining substantial drive and control with the dimensional, harmonically rich presentation associated with Conrad-Johnson. The A version delivers roughly 275 watts, while the XS uses EL34s and produces about 135 watts, so matching the exact version to your speakers matters. Confirm tube age, bias stability, service records, and whether the original output-tube socket wiring has been reinforced; tube life and that known maintenance issue materially affect value.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Conrad-Johnson emerged in the mid-1970s from the dissatisfaction of two American economists and audiophiles, Dr. William Conrad and Dr. Lewis Johnson, with the inconsistent performance of contemporary amplifiers. Founded in the United States, the company launched its inaugural product, the all-vacuum-tube PV-1 preamplifier, in 1977, quickly earning critical acclaim and establishing a benchmark for musicality. This debut propelled Conrad-Johnson into the forefront of the tube renaissance, with the iconic MV75 power amplifier following in 1978, solidifying its heritage as a pioneer in high-end audio craftsmanship.
The brand specializes in vacuum-tube preamplifiers and power amplifiers, renowned for their warm, engaging sound that prioritizes musical satisfaction over sterile measurements. While tube designs remain its cornerstone, Conrad-Johnson expanded into solid-state amplifiers and phonostages in the 1980s, alongside limited ventures like the Sonographe turntable line and electronics acquired in the late 1980s. All components are hand-built in the USA using simple circuits and premium custom parts, reflecting over four decades of refined design philosophy.
Conrad-Johnson holds an exalted position in the high-end market as an American classic, beloved by audiophiles for gear that "just sounds right." Its products command lust among enthusiasts worldwide, blending vintage appeal with sustained relevance, and consistently rank among the most musically rewarding options available.
