Review: Spectron Musician III Signature Edition Amplifier


Category: Amplifiers

This review is of the newly released Spectron Musician III "Signature Edition" MSRP $5995. The signature edition has improvements over the $4995 standard version (which is an exceptional amplifier as-is) that improve the specs and sound to the degree of making it a strong competitor to $20K-40K reference monoblocks. John Ulrick (former co-founder of Infinity and creator of the first digital amp in 1974) has really outdone himself with this new design. The Musician III Signature version is one of the most natural, detailed, robust and transparent amplifiers I have ever had the pleasure of listening to. The soundstage is so vast that when I closed my eyes, my once constricted sounding listening room sounded like someone snuck into my new home and added an extra room behind the speakers! Ok, I may be exaggerating about the stage a little bit but not about the clarity, detail and bass authority. This amp is POWERFUL and difficult loads do not even phase it. I have MBL 111E Omnidirectional speakers connected to it. I originally focused my attention on the ship anchor sized MBL 9011 monoblocks and fell in love with them at CES 2005. The Spectron was purchased to be a temporary place holder until I could afford the MBL giants. After purchasing this tiny, less than 60 lb. digital powerhouse, I have no desire to shell out for Monoblocks that cost as much as my new BMW 5. Everyone recognizes that the new digital designs are powerful and efficient but there exists an industry wide stigma about the musicality of most digital designs. Many inexpensively or poorly implemented digital chip based designs simply do not have the warmth and natural sound of the finest tube and class A solid state amps. The Spectron Musician III Signature is in a category all by itself. I enjoy listening to cello and piano. I ran through about 2 hours of "The Essential Yo Yo Ma" and was shocked. The Spectron revealed nuances and micro details that I never noticed previously on tracks that I listen to frequently. The bass is robust, strong and very controlled. The Spectron sounds nothing like many of the digital ice-power or tripath based designs. The Spectron is very transparent. What comes out of it is exactly what you put into it. Use a great power cord and exceptional source equipment and you cannot lose with this amp. Other Spectron owners tell me that tube preamps such as BAT are a perfect companion for the Spectron. If you are considering purchasing a new amplifier in the $10000+ category, you owe it to yourself, and your wallet, to give the Musician III Signature a listen. Be sure to have a pair of well respected tube or solid state amps that cost at least twice as much in the same room for A/B comparison. You will be amazed! The manufacturer burns in the amps for a week or so at the factory and informed me that I need to give it at least a week of burn-in at home to fully appreciate it. After a few hours of warm up, right out of the box, it sounded great. I am on day 4 of listening and it just keeps getting better.

Strengths: Powerful, Open Soundstage, Critical Midrange is natural and dynamic. Nice build quality. Pretty Face

Weakness: No rack mount option at this time.

Hi Rafel, with the limited experience I have, if a device was truly designed to operate in balanced mode, it often sounds better and more fleshed out when connected that way. E.g., I have a system consisting of an Esoteric X-01 Limited, an ARC Ref 3 linestage, and a pair of 1988-vintage Rowland 7M monoblocks. X-01 has balanced output, Ref 3 is completely balanced in input and output, and JRDG 7 M have balanced inputs but SE output. ICS are both Audioquest Sky balanced XLRs. If I turn off the balanced signal on the Ref 3 through the remote, not only I lose sound volume, but the sound becomes significantly vapid and gutless. Admittedly, I have not tried to operate the system using single ended SKY RCA ICs. By the way, it looks like I was wrong about conductors in the Spectron speakerwire: there are 4 conductors, not three. Please let us know any experience with Spectron in balanced monoblock configuration if you have the opportunity.
Hello Guido,
I know a guy in California who has two standard Spectron Musician 3 i.e. older non-Signature Edition. I will askhim to run them in monoblock fully balanced mode. What would be very interesting!

Hi Rafael, I am looking forward to hearing about how the Spectrons behave in fully balanced mono configuration. With the little experience I have gained, I find that in many cases if equipment has been designed to run balanced, it often sounds more fleshed out that way. E.g. I have a balanced system as followes: Esoteric X-01 Limited differentially balanced in the output, ARC Ref 3 differentially Balanced input and output, Rowland 7M with balanced input and single ended output. ICS are AudioQuest Sky XLRs. Normally the system runs in fully balanced mode. If I turn off the balanced signal on the Ref 3 through the rmote control, the sound not only loses volume, but also becomes comparatively vapid and uninvolved. By the way, I was wrong about number of conductors in the Spectron balanced speakerwires: the wires have 4, not 3 conductors.
There is some indication that the NuForce amps may be leaking RF, causing havoc with some FM radio tuners/receivers. Has anyone experienced any such issues with Spectron Musician 3 Sig?
No, Guido, Noooooooooooooooooooooooooo!!!!!!!!!!!!!!!
No, No, No !!!!!
RF leakage is very, very bad, I listen to my tuner, 10 inches from Spectron.
I bet that Jeff Rowland also does not leak
