A look at some high powered amplifiers

[MUSICRAFT]

Can someone please also add pictures of Gryphon's Mephisto mono and Antileon EVO mono power amplifiers please.

Thanks

It requires 12kW to run it! Yes that means 10.5kW is converted into heat which is about the same as boiling ten kettles at once. *fool*

Got air-con don't you?

Or put cooker hoods over your amps?

Gross!

I can just imagine these in some tiny apartment in Tokyo with a pair of old LS3/5As hanging off the end of them from cables having a minimum bending radius of about 2 metres!

You hang em off cables from the ceiling or something like that and they act as asynchronous oscillator earthquake dampers...

This reminds me of something:

Bertie: That's an ambiguous contraption, Jeeves. What is it?

Jeeves: I believe, sir, it is a music making machine. It needs feeding with electricity. The design is influenced by the Art Deco movement.

Bertie: Well, cover me in eggs and flour and bake me for 40 minutes. Isn't it a trifle large - won't it obscure the light, Jeeves?

Jeeves: May I be permitted to suggest only one smaller alternative, sir?

Bertie: Only one?

Jeeves: AVI. They design active speakers. Very petite in stature - it is claimed to be superlative to any other device, regardless of price... and will remain so for the next 80 years.

Bertie: Well, snakes alive! That's hardly sporting, is it?

Hi gasolin and chebby

Thanks for posting the pics.

All the best

Don't do poetry. I used to write scripts (screenplays) and made a bit of money from it, before and during my local script writing group.

250,000 Yen in 1980, 200 watts into 8 ohms, 10.5 kgs per channel.

OUTPUT POWER BEFORE CLIPPING 120W rms @ 8 ohm 130W rms @ 5,6 ohm 100W rms @4 ohm

Looks like a very mediocre amplifier, that needs friendly speakers (with a benign impedance curve)... *scratch_one-s_head*

The latest from Dan d'Agostino is a three kilowatt monster. No idea how to post pictures here.

Paul Miller's measurements confirm the awesome power delivery of the Momentum M400 -
"...In practice it bests this by some margin at 430W/8ohm and 810W/4ohm witha dynamic output of 475W, 940W and 1775W into 8, 4 and 2ohm and with a scary 3010W (that's 55A) into 1ohm."

I don't think 79 strand would do for that... I gather they weigh about 43 kg each (channel).

I agree. The Krell above shows how to do it! Oops, I mean the d'Agostino

But the Ypsilon costs 2000 GBP per kg!

Look at the 3 pin plug at the the back of this one !

Boulder Amplifiers, which is based in Colorado, released a new Class A amplifier at CES that operates only at 240V, and which it claims is ‘the world’s most powerful and accurate home stereo amplifier’. The new Boulder 3060 Class-A stereo amplifier is rated with a power output of 900-watts per channel into 8Ω. ‘At nearly 450lbs and producing 900 WPC, the 3060 is by far the largest and most powerful stereo amplifier ever released by Boulder,’ said Rich Maez, Director, North and South American Sales and Marketing for Boulder. According to Maez, the 3060’s audio circuitry is largely based on Boulder’s 3050 monobloc and uses 120 semiconductors in the output stage, whose bias currents are actively monitored and adjusted in order to increase efficiency and reduce wasted radiated heat energy. ‘It is capable of massive current swings, enabling the amplifier to drive any loudspeaker to realistic performance levels and units will only be shipped operating at 240V a.c. in order to guarantee full-rated power output. No 100V or 120V a.c. units will be produced,’ said Maez. All the metalwork on the 3060 is produced in-house at Boulder, using Boulder’s own CNC machining facilities and features the distinctive angular appearance unique to all 3000 Series products. Each amplifier comes standard with a black granite and stainless steel base. Only US prices were quoted at CES, with Maez telling Australian Hi-Fi Magazine that the 3060 would retail in the US for $US115,000. ‘The 3060 is the second release in the 3000 Series and showcases Boulder’s latest thinking in amplification technology. The 3060 also expands the 3000 Series product line and marks a substantial improvement in performance over Boulder’s own 2000 Series, moving the game on from what has long been considered the benchmark in high-performance audio amplification,’ he said. ‘This sets the stage for numerous future developments in other series of Boulder products.’

I suppose I could include my Electro 180 monoblocks.

They are not as powerful as some on this thread but they can still kick some @rse.

Electrocompaniet AW180 monoblocks, 250wpc continuous into 8ohms, 380wpc continuous into 4 ohms, 650wpc continuous into 2 ohms , stable down to 0.5 of an ohm, 22kg each, 100 amps peak current delivery each.

Transient power rated as several kilowatts .

First made in 1994 and still in production today with only minor upgrades to some components.

A picture of one monoblock .

An earlier model.

Apologies ... it's a Wyred 4 Sound SX-1000R Class D Monoblock and costs $1199.

Can't do the pics, but does my not so impressively slimline Yamaha MXD1 qualify? 300wpc into 8ohms, 500wpc into 4ohms continuous. Would love to get hold of the matching passive pre-amp...
