Summary:
Spectron Musician III MKII Signature Edition is truly an oustanding audio amplifier whith sonic presentation that I have never heard before.
There are many owners who have placed detailed reviews here that I am in complete agreement and no need for me to replicate the sonic details.
I operate a pair in mono to feed left and right woofers, single stereo unit to feed mid/treble for both left and right panels. Speakers are large planars Analysis Audio Amphitryons.
My 3 pcs are fitted with the V-Cap and Byee Bee upgrades and I will eventually get a fourth Spectron MIII KII SE.
There are many other amps that I have owned in the past - solid state, tubes and hybrid designs none of which could really make severals planars for the past 30 years, realy sings. Bass presentations always lacked what I was looking for.
With my Spectrons NOT SO.
Magnepan MG 20.1(which I also own) along with the Amphitryons generates bass like no othe amps that I have owned. Deep, taut and loud distortion free a close sense of live music being played.

Strengths:
Makes music sound really life like and totally balanced from top to bottom.
Most amps that I have owned paid more attention to the mid/treble areas only
(I called them PA amps)
Build quility is in par with all the other top manufactures who fits large front handle bars on their 50 lbs faceplate which does nothing for the music.
Easy for me to lift up without any help from someone else, runs cool and is mechanically dead quiet. Physical size is easy to work with.
Price is a real deal for the music you are getting.

I have now finished my time spent with conventional Class A/B amps and feel that thses amps have reached their limits.
All Class D amps are not equal and should not be judged as for this, but by listening to the Spectron music played.

Weaknesses:
There are no weakness that I can find.

Similar Products Used:
I have compared my Pass Labs line up with the Spectrons.
2 pcs X350.5 stereo, mono pair X600.5 and mono pair XA200.5, enough metal here to build a small war tank and heating up a 2000 square feet home.
No matter what type of config I used with the Pass Labs, the Spectrons are far ahead playing music through my planars.
Even at identical low level listening between the Passes and Spectrons, the Spectrons are more superior.
In my set up the Spectrons are really something else playing music extremely loud without increased distortion.
As far as I can remember here are some amps that I have used with planars in the past, but not a fair comparison to the Spectrons, since these are older manufactured amps.
Roberston 4010, Dr Tim Ref, Moscode, Radford Renaissance, Crown Macro Ref, Bryston 4 B, Classe 25, Simaudio W5 and W10, Sonic Frontiers 3, BAT 150 SE, ARC M300, Rogue Audio Zeus.

Summary:
I have a B&W system consiting of all 800 series speakers. The Spectron Musician III SE MK2 drives my 803Ds. They are nominally rated at 8 ohms but can dip to slightly below 3 ohms and their recommended power is 500 watts/channel.

I had listened to the speakers when I bough them with the McIntosh 402 and Classe CAM 350 and 400 mono-blocks and thought they sounded best with the Classe mono-blocks and began saving for them. In the interim I had them running off a Rotel RB-1090 (380 watts/channel) and knew the speakers could sound their best with better amplication. I was set to buy the Classe mono-blocks when I read some reviews of the Spectron. They were so overwhemling here and on other audio forums that in a leap of faith, I bought the Spectron and went through the 400 hour burn in process. In a word, WOW! I never heard my speakers sound so good.

I wan't sure where to post this review but I am using a single amp, not mono-blocks and I can't imagine what two of them would sound like since just the one has ended my quest for the amplifier I have been searching for.

My speakers produced sound with amazing headroom extention but without any harshness at all. It was like the Classe without the 'veil'. The midrange is sweet, detailed and musical while the bass in all ranges in very tight, rich and powerful but in complete balance with the other hormonics. Soundstage and other audio characteristics were simply outstanding.

Had I bought the Classe I would have had to rearrange my entire audio sytem and bought new interconnects and speaker cable. The Spectron in this small 52 lb package does it all without having 300 lbs to arrange; it can fit anywhere. You leave it on 24/7, draws only 40 watts, and only gets slightly warm.

I don't know what else to say other than I wholeheatedly recommend this amp.

Strengths:
Mentioned above.

All the reviews I read here before purchasing the Musician III SE MK2 are absolutley correct. Spectron has made steady and evolutionary changes to their earlier products and each step forward to a new product made it what it is today.

I belive this will be their stable and futue production model for some time.

V-Cap Option for those who want the ultimate in finesse and liqudity in sound from the amp.

Weaknesses:
Just the run-in time but you can hear the improvements in sound quality every 100 hours until you reach 400 hours.

Of course, I would suggest a premium aftermarket power cord for this (or any) high quality amp.

Summary:
I've listened to a lot of amps over the years, and built a few, too: mostly triode tube amps. As the years passed, my audio budget became more ample, and I have been able to try just about all the "killer" amps out there, tube and solid state. The good news is that the art form is actually improving. The bad news is that audio mags and their advertisers have done a great job pushing the price of amplification skyward. But I was prepared to suck that up, and just get the "killer amp" that would make it unnecessary to wring hands again about amplification. At least for several years.

Hearing the Spectron Musician III Signature has put an end to my amp questing. There just is no amp out there that combines the authority, tonal rightness and delicacy of this amp. It will drive anything, and laughs at tough loads that send a lot of amps into deep depression. {I've used it with the Shahinian Diapasons (19K), which are notoriously tough to drive, and also with the new Fried Reference (25K) which are not) But what really blew me away is how the M3 Sig does so with utter transparency and tonal accuracy. Its treble reproduces the almost-impossible-to-reproduce sound of massed violins with no haze, no glare and enough vividness that you feel you can hear the rosin on the bow. Voices have the kind of immediacy that many associate with single ended tube amps. And when it is time for the kettle drums in Malher, or the juicy bass of, say, Charlie Haden, the amp controls the speaker with complete authority. Not just firm bass; rock solid, clean, REAL bass. [NB I was a symphony musician for several years. Sitting in the middle of an orchestra really teaches what real instruments in real space sound like.]

All of this performance for so few dollars, comparatively, and with complete reliablility and no furnace effect. Yikes!

I was prepared to spend up to 30K for amplification, and end the quest. I was thrilled to spend less. But I am even more thrilled to be out of the amp-comparing business. Its just not as good as listening to the music

Strengths:
Immense musicality yet truthfull to real life music, combined with more then modest price

Weaknesses:
None worth mentioning

Summary:
I have owned the Musician III Signature amp for 3 weeks and it has been breaking in continually for some 500 hours now. I recently purchased a pair of MBL 101 speakers and the review is of the Spectron driving the MBLs. The MBLs are blessed with some of the finest treble and bass performance that is possible. And their staging is extraordinary. Upfront, I can state with no reservations, that the Musician III Signature is fully up to the task! The strength's of the speaker are beautifully complimented by the Spectron. In addition to the above, dynamics, resolution, clarity and speed abound.

I guess the biggest surprise is how good it is. I am used to owning very expensive amps and used to the musicality of single ended triodes. How can an ultra-high-powered digital amp sound this good? The Spectron is truly an open window to the sound of what precedes it. It does not editorialize. The sound of my MBL-based system changed dramatically when I changed my line stage from the wonderful Connoisseur to the even-more-wonderful sounding BAT REX. It was literally as if I had changed amps
I have a high quality XRCA of female vocals. Until this latest change, I could not stand to play it. Voices were just plain wrong (12 different female vocals). Now they sound wonderful.
I have been listening to two of my all-time favorite jazz records; only two musicians on each, a saxophone and piano. One record is all blues, the other all gospel. Archie Shepp and Horace Parlan are the musicians. I have enjoyed these treasures since the early 90's. Never have they sounded so wonderful as they do now. The richness and fullness and absolute musicality is stunning. This stuff can bring one to tears, if you have any "soul," that is, and I do. I really do not know where to heap praise, since this level of excellence did not appear until the REX joined the parade, yet it is the Spectron that is passing it through. The Spectron adds no amusical coloration, which our ears percieve as "steely or piercing" sound nor any euphonic coloration - It's just a huge open window to "live" music.

Last night, my wife and I spent an evening with a friend of hers who also played piano for us for an hour. We sat 3-10' away (2 different positions) and I was reminded, once again, of the amazing power and dynamics of a live piano. What I would consider to be "bright, "hard," or "peaky" on my stereo system was in fact the sound of the live piano. Oh well, live and learn.
With the Spectron and MBLs, I can virtually replicate the sound we heard live last night
For the first time in my audio life I am hearing full orchestral music reproduced properly. The power, majesty and scale is beyond words. Organ shakes the walls. The 1812 overture with cannon shots are just unbelievable. Everything I thought I knew about what is possible has been trashed. I think that even John Ulrick do not know what his amp is capable of.
As a point of reference, I am using $50k speakers, $25k line stage, $25k phono stage, $30k phono, $30k digital AND an amp that cost me under $6500. It seems incongruous, but the amp is that good. My very high expectations have been exceeded!

Strengths:
Attractive, reasonably priced, unlimited power, world-class bass and treble reporduction and uncolored and spacious mid-range. Plus, customer service is the best! The really do bend over backward to please.

Weaknesses:
The only weakness is that we "perceive" moderately priced gear and digital amps to be less than serious high end products. That is a mistake, in this case, as it is a very high end product indeed.

Summary:
I purchased my Musician III in December 2004, after six years of experience with the original Spectron Class D amplifier -- the Digital One. My original impressions can be found in a review I posted in this forum via the following link:

http:www.audioasylum.com/forums/amp/messages/69081.html

Compared to the earlier Digital One (and other similarly priced amps I auditioned at the time), the Musician III was incrementally better in mid-range tonality, bass extention and clarity, micro-dynamics and detail. Even more dramatic improvements were evident in presence of a wide, deep soundstage, a sense of deminsionality and imaging, and a high degree of transparency, space and "air". Most important, the MIII proved to be an excellent match for my rather inefficient B & W Nautilus 802 speakers.

After two years as a very satisified user, John Ulrick of Spectron convinced me that moving to his new Signature Edition was well worth the price of the upgrade ($1250.00). And although I have currently less than 200 hours burn-in, it's clear that John was not exaggerating. Specifically, tonal accuracy in the mid-range and treble is dramatically improved (natural and totally uncolored); the bass is even more extended and muscular; and the sound stage more spacious, especially in depth, with greater imaging and delineation. The Signature Edition is a result of major improvements made by John which take the Musician III well beyond its prior level of performance, which was reviewed so favorably in Absolute Sound last November.

Having said all this, let me offer two pieces of anecdotal evidence:

First of all, after somewhere between 100 and 200 hours of casual listening, I was playing a ten year old classical CD that I am very familiar with, and it suddenly occurred to me -- the music was far more alive with a liquid, silky sound that I had never heard before. It made me feel like I was actually in the presence of live music. Quite an amazing reaction!

Secondly, at a listening session involving a few others from the local audio society, one knowledgeable member observed that he had never heard my Nautilus 802's sound so good. Most of the participants had never been that impressed with B & W speakers (having other personal favorites), but the consensus of the group was that the 802s had obviously come into their own and really sounded good! Obviously, the muscle and speed of the Specton with the Signature Edition had finally gotten my hard-to-drive behemoths to really blossom.

Finally, let me say that their are two configuration changes that I have made to my system over the last year or so that I consider absolutely essential to getting the best performance out of a Spectron amp: 1) I added an Exact Power 1000 power regenerator to my system solely to support the amp. As John Ulrick says, the Spectron Class D architecture "loves constant, pure power with very low distortion". And 2) I have connected my universal player (a APL Denon 3910 with digital volume control) directly to the Spectron, dropping my pre-amp entirely. The synergy between the CDP, the Spectron and my speakers seems to really cook!
