  • PBN Audio Olympia LX Preamplifier w/ Mini Power Supply & NEW Volume / Display updates in Silver

    $6,000.00

    The Olympia-LX preamp is an all-FET design with an external MPS mini power supply (9.5″W x 4.25″H x 14.25″D) that has a 375VA transformer with 80,000µF of capacitance. The main transformer features quad secondary windings and HEXFRED diodes for rectification. A proprietary, military-grade, 14-conductor connector of 16-gauge Teflon-sheathed silver wire — a serious umbilical — joins the power supply to the preamp proper, which measures 18.5″W x 4.25″H x 14.5″D. This main unit houses four independent regulators and provides 20dB of gain. The Olympia-L’s front panel has a blue LED indicator light, a sensor for the remote control, a NEW updated digital volume control (63 steps). A  source selector (two Aux, one CD, two balanced). All controls are clearly labeled in white silk-screened letters, demonstrating what Noerbaek calls his “function without frills” approach to exterior design. All can be adjusted manually, but the small metal remote is far more handy for setting volume and mute. On the Olympia-L’s rear panel are three balanced inputs, two RCA inputs, and balanced, RCA, and the four BNC outputs for the proprietary interconnect system — which, of course, is impedance-matched at 75 ohms.

  • McIntosh C-29 Stereo Preamplifier Vintage Classic looks good and works well, missing input ring

    $2,200.00

    BASS CONTROLS

    Separate 11 position rotary switches for each channel, +20 dB to -20 dB at 20 Hz

    TREBLE CONTROLS

    Separate 11 position rotary switches for each channel, +18 dB to -18 dB at 20,000 Hz

    BALANCE CONTROL

    Natural balance at center position, attenuation of left or right channel by rotating control

    PRECISE TRACKING VOLUME CONTROL

    A precision step volume control with left to right tracking accuracy within 1 dB through its entire range.

    SIX SOURCE INPUT SELECTOR

    Auxiliary 1 and 2, TUNER, PHono 1 and 2, MICrophone

    MODE SELECTOR

    Seven positions: Left channel only to both speakers, Right channel only to both speakers, Stereo Reverse, Stereo, Mono, L + R to left speaker only, and L + R to right speaker only

    TAPE MONITOR SWITCHES

    Two pushbutton switches. Either of two tape recorders can be monitored by selecting the TAPE 1 pushbutton or TAPE 2 pushbutton.

    They are mechanically interlocked to accept only one pushbutton at the IN position at one time.

    TAPE COPY SWITCHES

    Two pushbutton switches. Either of two tape recorders can be connected to copy from tape recorder 1 to tape recorder 2 or vice versa.

    They are mechanically interlocked to accept only one pushbutton at the IN position at one time.

    LF – HF FILTERS

    Reduce unwanted high frequency noise (above 7 kHz) and low frequency rumble etc. (below 50 Hz) at 12 dB per octave rate.

    FRONT PANEL TAPE JACKS

    Allows connection to input and output of a tape recorder from the front panel. Inserting plugs into the front panel jacks disconnects the TAPE 2 circuits from the rear panel and uses the TAPE 2 facilities for the front panel jacks.

    HEADPHONE JACK

    For listening with either low or high impedance dynamic stereo headphones. Power to this jack is supplied by an amplifier in the C 29. Headphone listening can be accomplished without the use of an external power amplifier.

    SPEAKER SWITCHES

    (Operates with accessory speaker control relay) Turn Two sets of speakers on or off when properly interconnected with the accessory speaker control relay (the McIntosh SCR 2).

    MAIN OUTPUT LEVEL CONTROLS

    Permits the balance of the entire system to be conveniently preset.

    HEADPHONE & LINE OUTPUT LEVEL CONTROLS

    Adjusts the level and balance of the HEADPHONE/LINE output.

    YOU CHOOSE FROM EIGHT DIFFERENT PROGRAM SOURCES

    The input switch selects from six different sources or you can choose to listen to either of two tape recorders at the push of a button.

    PRECISION STEP ATTENUATOR VOLUME CONTROL

    Ideal volume control tracking accuracy and noise free performance are two of the considerable benefits of the McIntosh Precision Step Attenuator. It is a thirty-two step, 70 dB range control with unheard of tracking accuracy within 1 dB. The extreme accuracy is obtained through special electronically controlled resistance element trimming. The accuracy and quiet operation are maintained because the switch commutator touches only the switch contact pad and not the precision resistor elements.

    AUTO TURN ON/TURN OFF

    Power to the entire stereo system can be controlled from either the front panel power switch or the turntable’s power switch. A current sensing relay connected to the turntable AC power outlets is controlled by the turntable power switch. The relay, in turn, controls the AC power to the remainder of the system.

    STEPPED TONE CONTROLS INDEPENDENT IN EACH CHANNEL

    Settings are precise and repeatable in each channel, independently. Each tone control is a separate eleven position switch concentrically mounted. Each step is connected to carefully selected resistors and capacitors to give the precise frequency curve shape. Because the tone circuit component parts are not in contact with the switch surfaces, as in ordinary continuously variable rotary controls, they never change, never get noisy and provide exact, repeatability settings.

    YOU ALWAYS GET THE IDEAL STEREO IMAGE

    The McIntosh seven position mode selector has facilities to permit the correct balancing of a stereo system to maximize stereo imaging.

    YOU CAN LISTEN AT LOW VOLUMES WITH EQUAL PLEASURE

    A continuously variable loudness control lets you enjoy full frequency response and warmth of music regardless of the room volume you choose. As volume is reduced, the frequency response is adjusted to complement the human ear response characteristics, the Fletcher Munson effect.

    TAPE RECORDING AND PLAYBACK MADE EASY

    Tape input, tape output and switching facilities are provided for two three-head tape recorders. Simply push a button to listen to either one, or – record from any selected source on either or both, or- copy from one tape recorder to another while listening to an entirely different program. You can instantaneously monitor either tape recorder.

    STEREO MICROPHONE INPUT MAKES RECORDING EASY

    Microphones in stereo may be used with the C 29. By tuning the input selector to MIC the microphone set-up will be connected to either one or both of the two tape recorders connected to your system.

    THE CONSTANT LOUDNESS BALANCE CONTROL

    The McIntosh balance control adjusts each channel independently for stereo imaging without changing overall stereo volume in the room. While natural balance is at the center of the control; adjustment to either right or left compensates for program variations or room acoustic differences.

    LISTEN TO YOUR QUIET RECORDS, QUIETLY

    Any unwanted noise (hiss, rumble, fry, etc.) can be reduced with the filter switch. It allows the reduction of low frequency noise and high frequency noises (below 50 Hz and above 7 kHz).

    CONTROL REMOTE LOUDSPEAKERS FROM YOUR PREAMPLIFIER

    Through a unique McIntosh design, you have ON/OFF control of two separate sets of stereo speakers when used with an accessory switching relay (the McIntosh SCR 2).

  • Bel Canto – C5i Integrated Preamp Amplifier w/ phono, digital inputs USB and remote

    $850.00

    The C5i is powered by B&O ICEpower and gets a single 125ASX2 module. The Danes rate its S/N ratio at an impressive 117dB A-weighted. Given its 60/120wpc 8/4Ω rating, this amplifier module is surprisingly compact – all of 16 x 8 x 3.5cm. For D/A conversion the C5i relies on a 24/192 Wolfson WM8740, for its 24/96 USB 1.1 input on a Texas Instruments TAS1020B transceiver, for asynchronous sample rate conversion on a BurrBrown/TI 4382. For the line-level and phono inputs there’s also a dual-bit delta-sigma 216kHz AKM5386 A/D converter. This conversion of analog signal points at exclusively digital-domain volume control—in 200 x 0.5dB steps.
