"Centaur" .......... Buck 65 :-) .........

This amp far from doubles it power which the maker wants you to belive, in fact it actually goes backwards in the 2ohms!!!

Published
500Wpc 8 ohms
1000Wpc 4 ohms
1600Wpc 2 ohms

Actual
550Wpc 8 ohms
880Wpc 4 ohms
700Wpc 2 ohms

When are amp manufacturers going to wake up and tell the truth.

Cheers George

There must be something skewing that 2-ohms number, since the lower resistance/impedance should increase the wattage. I wonder what that something is.

slcaudiophile's picture

agreed ... i was shocked when i read that too. but i guess at the same time, who needs 500 Watts anymore? but i agree, manufactures should always be conservative with power ratings.

Anybody remember the Chord SPM 14000 Ultimate monoblock power amplifier?

Same as it ever was.

It is not like 3 strikes .......... One measurement was (close to) a hit (for Constellation) :-) .........

Bogolu Haranath's picture

Think about this ......... When the new Centaur III comes out this one can be sold for 1/3rd the original price in the used market :-) ..........

dalethorn's picture

"The diamond dogs are poachers and they hide behind trees...."

And this amp will sell for double its original price, as a heater on cold winter nights in the post-apocalyptic city.

The internal layout is atrocious; with such haphazard wiring running wildly this way and that, two things become alarmingly clear:

1) QC is non-existent
2) no two amps from this laughable, but sad company will sound the same as a result.

If 'Constipation' products even 'last' 5-years I'd be surprised, as I would if it retained 10% of its original value over the same time frame.

What an ugly joke of an amp/company.

...which costs only $9K for a pair of monoblocks.

Published
400W 8 ohms
800W 4 ohms
1200W 2 ohms

Actual
586W 8 ohms
1154W 4 ohms
2255W 2 ohms
(4200W 1 ohm)

Also, for $55K, you'd think that Constellation could do a better job than this rat's nest of wiring:

I have it on good authority from a fellow local Hi Fi Club member that if it costs more, it must be better.

That trumps Parasound, soundly.

;-D

Bogolu Haranath's picture

All those internal wires are cryogenically treated with a "secret sauce" ........... So, they acquire all that musicality ......... It is a very expensive process, and hence the enormous total price tag :-) ........

Bogolu Haranath's picture

If we match-up the recently reviewed $45,000 CD player with this amp, the sound is sure gonna be "heavenly" :-) ............

Ortofan's picture

... your local Hi-Fi Club member.
From their Reference series product line comes the Hercules II stereo amp. Priced at $90,000, it must be almost twice as good as the Centaur II 500.

Bogolu Haranath's picture

Hercules II does not weigh 300 pounds ......... So, it can't be twice as good :-) ............

... the 355 lb. Boulder 3060:

Not if the current's not up to it, either the powersupply or output stage.

Cheers George

any amplifier equipped with "some" 3000w power transformer could ever provide continuous output of 1600w simultaneously per channel – or anything close for that matter since there is always more to be stably fed in a power amp than merely output transistors. Curious thing is that Constellation Hercules II stereo amplifier that sports twice the aforementioned transformer and presumably larger output stages comes along with more conservative specifications which most probably will be exceeded by the actual measurements at the test bench.

tonykaz's picture

doesn't that phrase have to do with a "Bubble-Gum" daughter of a "Captain of Industry" describing the desirability of a $5,000 Fendi Purse?

Isn't our age group already too close to Oakwood Cemetery's Waiting List to consider our next Amp as one to "die for" ? Phew, maybe I should hunt down a vintage conrad-johnson MV-45a whilst hoping for another 3 Decades.

or

maybe we should consider this Amp's imaging as something: To Live For !!!

Dear Editor JA,

Your wonderful yet quirky reviewing twins have discovered 16 ohm output resistors. It seems that Nelson Pass has been informing your Staff. Steve & Herb are "to live for" .

No, it has to do with the hypocrisy of selling expensive gear and then decrying others who also like to enjoy the finer things of life.

Bogolu Haranath's picture

They tried twice and still couldn't get the measurements right ......... Let us wait another year or two and they may come out with Centaur III with better measurements :-) ...........

dalethorn's picture

Maybe we're missing the real quality here, blinded by "measurement". For example, what if the amp has a secret technology that reduces the power value in direct proportion to how it produces a purer cleaner more musical signal, but does so in such a way that the sense of dynamics is even more breathtaking than indicated in the review? That, or I just wrote the best ad copy this year.

Bogolu Haranath's picture

Constellation Audio thanks you for your support and free promotion. Centaur III is gonna be even better (sounding). They want repeat buyers :-) ..........

Anton's picture

Perhaps we are simply seeing the current paradigm of making up "alternative facts" and people being OK with that, and it's leaking into Hi Fi.

Constellation should call it a 2,000 watt per channel amp, the most powerful amplifier, ever. It is such a winning amp that audiophiles will get tired from all the sonic winning it does?

Bogolu Haranath's picture

Thank you JA for the measurements .......... Stereophile is the only hi-end magazine providing comprehensive measurements for audio equipment (so far) :-) ............

Axiom05's picture

A $55K amp and they can't warrant it for more than 3 years? Bryston gives a 20 year warranty, should be an industry standard.

tonykaz's picture

... Schiit outfit in California that makes all their gear in the USA! Phew!!

Tony in Michigan

ps. Zippo lighters all have a "Lifetime" warranty ( for gods sake ) and they seem to appreciate in Value as they get older.

Bogolu Haranath's picture

Those lighter guys know that those smokers don't live for long ......... So, no problem :-) ............

dalethorn's picture

I think Koss has a lifetime warranty on their headphones, and the plan seems to be that you eventually get tired of sending them in and just buy a replacement.

dalethorn's picture

Here the longest person who ever lived (to 122) smoked until she was 117. The reason she lived so long smoking is because she smoked Centaur cigarettes (rebranded Chesterfields actually), although due to copyright issues, Guinness doesn't mention the brand.

Herb Reichert's picture

In the 1990s, when I represented Kondo/AN Japan, their amps came with a lifetime parts and labor warranty - except tubes. We usually sold these amps with a back up set of NOS tubes. After 20 years, most owners have not touched the back up tubes.

steverman's picture

I wonder if those making the remarks have actually heard this amp. I heard it at a friends place and it sounded absolutely sublime. It didn't run hot actually. I thought it sounded like a Class A amp, but it never got hot. He was using it with a tube preamp, but it was the best amp I have heard at his home, and he's owned alot!

Anton's picture

It may sound great, so why lie?

allhifi's picture

I can't imagine I haven't replied to this abomination of a high-school tech project gone bad.

Constellation 'hack's' (including "supporter's" Harley & company) have absolutely no shame, dignity, design/construction capability, honesty, any sense of minimum quality standards nor craftsmanship, whatsoever.

This beyond laughable POS high-school failure of an excuse design- construction project is an unmistakable, unfathomable rip-off "project" that surely must have been designed as a joke to do nothing but 'poke-fun' at anyone who either raves of its "quality" -or god forbid, purchases it.

It's a piece-of-junk. Nothing more. Nothing less.

Comparing it to 'Lamm', 'Levinson', SimAudio, etc. should be detested by all readers and/or listener's who value engineering 'chops' and precision manufacture -both of which 'Crapellation' fails miserably. And shamelessly.

Unconscionable. UGLY. Figuratively. Literally.
