You are bidding on a mint pair of Primaluna Prologue 6 power amplifiers.  Each amplifier boasts a compliment of 4xE-L34 power tubes, 2x12AX7 a,d 212AU7.  All tubes are in very good condition.  The PrimaLuna Prtologue 6 was chosen as the "product of the year"  and "editor's choice" componet of the year by Absolute Sound.  The build quality is amazing.

The sound of the Primaluna is natural and balanced.  These are not your granddad's MacIntosh or your dad's Conrad Johnsons.  There not even your brother's Jadis. There is no heavy coloration or tube "glow".  No syrupy coloration. Yet, there is no hint of harshness or edge as found in many expense solid state designs.  Not romantic, not edgy...then what?  Just plain accurate.  In fact they tend to disappear.   What sets them apart is an effortless detail and sense of space that seems to be found only in the realm of tubes. 

These monoblloocks have distinct advantages to a similarly powered tube or solid state stereo power amplifier.  Sonically each amp has it's own power supplies so that each channel functions independent of the other.  A bass guitar on the left won't dissipate available power from a drum roll on the right, and dynamic range is often capable of more headroom.

As to functionality, mono blocks can be placed behind loudspeakers to aid in room appearance.  Mono amps are much more easily moved; a single amp weights about 40lbs., a similar stereo amp would weigh 80!  Finally, while there's been the raging debate over long interconnects versus long speaker cables, the majority of online references favor shorter speaker leads based upon the considerations of electrical design. 

And most impotantly, you do NOT have to bias the tubes, it happens automatically.  In fact you can mix and match tubes and the circuits will do the tweaking for you.  This takes the sound of tubes and couples them to modern design so that you can have the sound of tubes without the trouble.  Finally,each unique manufacturered brand of tubes has it's own characteristic sound. Unlike solid state you can easily change tubes to fine tune the sound these amps!

Primaluna states:

70 wpc and that famous EL-34 warmth that people love. The ProLogue Six starts with the same basic topology as the top-rated ProLogue One integrated amplifier. The monoblocks then reach a new level of performance using a unique dual-feedback topology: Cross-coupled current feedback for superior impulse behavior and gain stability. Next a slight amount of negative feedback is used to achieve exact gain setting, low distortion, and low output impedance. This effectively cancels the negative byproducts associated with both feedback circuits. The end result utilizes all the benefits of feed-back, without all the drawbacks.

Finally, the monoblocks integrate a newly-designed, wide-band, low-loss, output transformers, built to handle even the most difficult speaker loads. A two Ohm output tap is added for additional flexibility.

Like all ProLogue amplifiers, it boasts:

  • Soft-start circuit Extends component and tube life by powering up the amp gently every time you turn it on.
  • Tube plate fuse Protects the amplifier output stage. Other amps may need a trip to the shop if a tube fails. Not this one. Just plug in a new tube and fuse, and go.
  • Adaptive AutoBias. Exclusive to PrimaLuna, this circuit monitors and adjusts bias automatically. Each power tube is monitored to stay in a peak operating range. Improved performance and better sound, with distortion reduced by 40 to 50 percent over conventional designs. No need for matched tubes. No bias adjustments. Ever. It also allows you to experiment with different power tubes. Plug in virtually any power tube. Adaptive AutoBias will automatically adjust itself! In addition to EL-34s, you can use 6550, KT88, KT90, 6L6GC, KT66, 7581, EL37, and any of their equivalents.
  • Proprietary Custom low hum, wide bandwidth dual output transformers allow the monoblocks to drive most any spaker with ease. Read the white paper here.
  • Premium parts . Fully vented chassis, chassis-mounted ceramic tube sockets, Nichicon and Realcap capacitors. WBT style speaker terminals. Gold plated input jacks.
  • Hand made with the finest point to point wiring, with workmanship equal to or better than any product you can buy at any price, period.
  • Chassis made of finely finished heavy gauge steel, and five step automotive quality finish. Each coat hand rubbed and polished. Removable tube cage included no charge.
  • Toroidal power transformer for low hum, and a front end that is dead quiet.
  • Conservative design parameters: Though PrimaLuna amplifiers are powerful, tubes run well below their maxim ratings
