Linn LK240 mono power amps, pair

Reg. Price: $2400
Sale Price: $750

The Linn LK240 mono power amps were extremely popular in their day, with their compact footprint, great sound, and serious power output delivering 125 watts into 8 ohms and 240 watts into 4 ohms.  The LK240s can also accommodate Linn aktiv cards internally.  We have multiple pair available.  Box and packing included.


Rega P25 turntable w/ upgraded power supply

Reg. Price: $1935
Sale Price: $1050

Rega’s P25 turntable celebrated the company’s 25 year anniversary and remains a top performer today.  This used P25 has a maple plinth and has been upgraded to include Rega’s 24V motor and external TT PSU power supply.  It’s a one-owner table originally sold by us, in very good condition, with original box and packing.  Our client has now upgraded to an RP10, Rega’s top model. We’ve fitted a new Rega Carbon cartridge to get you started, but the Rega P25 is a solid performer and can justify any range of higher performance MM or MC cartridges.


Linn Lingo 3 power supply for LP12 turntable

Reg. Price: $1800
Sale Price: $900

The Lingo 3 power supply is a significant upgrade for an LP12 that’s currently fitted with an older Valhalla, Basik, or Majik power supply.  You’ll enjoy far more precise speed accuracy and stability as well as electronic 33/45 speed switching.  We will include installation at no charge with local purchase.  If you aren’t local, please be advised that we highly recommend you have a Linn dealer install the Lingo for proper results.


NAD D 1050 USB DAC / headphone amp

Reg. Price: $499
Sale Price: $329

The NAD D 1050 USB DAC is a terrific and affordable way to add computer audio and enhance other digital sources in your system. The digital inputs support balanced AES/EBU, coaxial and optical connectors. The USB input supports 192kHz signal transmission with an asynchronous operation mode and a high precision clock for lowest possible jitter. Balanced and low impedance single-ended outputs allow connection to a broad range of preamps. A discrete low impedance headphone amplifier rounds out the capabilities of this compact and affordable DAC.


Vandersteen 5A Carbon speakers, cherry

Reg. Price: $31,300
Sale Price: $19,995

Richard Vandersteen’s 5A Carbon speakers are one of the most critically acclaimed models of all time, loved for their remarkable 3D soundstage presentation, incredibly natural tonal character, and powerful bass response.  The 5A Carbons have onboard powered subwoofers with built-in parametic equalizers, allowing us during setup to create very linear bass response in most any room.  They require the use of Vandersteen’s M5-HP high pass filter, which goes in between a preamp and power amp.  This pair is our demo pair and includes full manufacturer warranty.  We will include delivery and setup in the N. Texas area at no charge; please contact us for shipping and setup options elsewhere.


Linn Keltik speakers with power amps and aktiv cards

Reg. Price: $22,155
Sale Price: $4900

Here’s a chance to enjoy a Linn Aktiv speaker setup complete with power amps and aktiv cards. Just add a preamp and source.  Keltiks were Linn’s top speaker at the time. This setup includes four pair of the Linn LK240 mono power amps- the optimal match for the speakers.  Also included are aktiv cards for the LK240 power amps, and Linn interconnect cables. We’ll also include Linn speaker cables in reasonable lengths.  You can select from a pair of Keltiks in black ash (shown) or walnut.  The black ash pair have no box and packing so local pickup only.  The walnut pair have original box and packing (as do the LK240 power amps) so this option can be shipped.  Keltiks are also available separately, please see other listing.  This is a terrific system for the price! Please ask any questions about placement, setup, compatibility etc.


Linn Akurate Kontrol preamp

Reg. Price: $5670
Sale Price: $1600

Linn’s Akurate Kontrol preamp is designed for music lovers and offers compelling performance in stereo, but can also process Dolby Digital 5.1 surround sound from its digital or multi-channel audio inputs.  The digital inputs are also a fine way to upgrade the sound of stereo sources like Sonos and Bluesound streamers, etc. The Akurate Kontrol also includes an on-board MM/MC phono stage. Terrific performance and value, there’s so much to enjoy with this used Linn preamp.  Original box, packing, and remote included.


Linn Urika I phono stage for LP12 turntable

Reg. Price: $3300
Sale Price: $1200

The Urika phono stage is cleverly designed to be mounted inside the Linn LP12 turntable, dramatically shortening the signal path from tonearm to phono stage and offering terrific performance.  The Urika is compatible with the Linn range of MC cartridges and many others.  It does require a Linn Radikal power supply, not included. Note that this is the Urika 1 phono stage which has analog outputs, not the Urika 2 which only has Linn Exakt outputs. Includes original box and packing, connecting cable to Radikal, and Linn Silver RCA output cables.  Please ask any questions about compatibility, installation, etc prior to purchase.


HRS S1 isolation base, 19×21

Reg. Price: $2195
Sale Price: $1495

HRS (Harmonic Resolution Systems) S1 isolation base, 19″ x 21″ in black finish, set for 70+ pound load range. The S series of isolation bases are our most popular and, we think, best value in the range.  Very nice improvement for most any audio component, our demo model has original box and packing and is in pristine condition.

Please note: demonstrator units (except for furniture) typically include box, packaging, and manufacturer’s warranty, and are in excellent condition. Furniture is for local sale only, as it cannot be shipped. Used components are in good working condition, however boxes, packaging, and manuals may or may not be available, and there is no warranty unless the original manufacturer’s warranty is transferrable.
