Spectron "The Musician II" Power Amplifier, 1.34 Horsepower to your Speakers!

If you ever thought that you wanted to measure power to your speakers in units other than the market-standard "watts" ~ yawn ~ Then the Spectron "The Musician II" power amplifier is the answer to your prayers. The advertised power of this amp was a stout 500 watts per channel into 8 ohms, the equivalent of 1.34 HORSEPOWER, or 600 watts per channel into 4 ohms.  If you do some research and read some reviews on this amp, it often delivered measured output far in excess of those numbers.  

What makes The Musician II different from other big power amps of the early 2000s era? It is one of the earliest examples of "Class-D" digital switching for controlling output transistors in a hi-fi application.  Other companies were making Class-D amps before Spectron, or rather alongside Spectron, but the founder, John Ulrick, found a way to make Class-D behave and sound like an audiophile amplifier should.  The Musician II doesn't suffer from saturation and "dryness" that other Class-D and Class-T amps of this era often succumbed to.  John's quarter-century of research into digital switching amplification led him to a "hybrid" approach where the digitally optimized signal is matched with a traditional output feedback circuit to improve signal correction with each iteration of the amplifier's power cycle. 

The result is a magnificent specimen of an amplifier. Presented in a rather compact (relative to power) chassis, the black anodized front panel is laid out simply - Just one big "Spectron" logo on the front like some kind of anonymous lab equipment. 

To top it off, John developed specialized (optional) cables which can be used with the amplifier's Neutrik style connectors. The Spectron "Remote Sense Cables" are included with this unit and are comprised of four conductors; the main two carry the audio signal, and the other two read the output voltage of the amplifier at the end of the length of cable and tell the amplifier to modify output voltage on-the-fly to compensate for line losses usually attributed to a cable's internal capacitance and resistance.  One reviewer wrote, "It's like attaching the terminal lugs of the amplifier directly to the speaker terminals." 

This Spectron setup is the full package.  Capable of powering any speakers, or possibly even running your shop welder. The amplifier was fully serviced in 2024 and includes the original manual and box for easy shipping. 

Don't miss out on this fun little piece of amplifier history. Giddyup!
