Acoustic Electronics Photon 6000 Monoblock Amplifiers - Super Rare and Powerful

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

These monoblock amplifiers are so rare that we could not find *any* information about them online. 

If you happen to know something about them please be sure to write us as we'd love to know more. 

We're not even sure of the total power output as they maxed out our test rig that's limited at 250W.  We did find a single but very brief post on a pricing website that mentioned 350W at 4 Ohms.  

On the bench we quickly noticed the build quality and parts selection.  Massive power supply capacitors and transformer, ingenious heatsink design, and a well built chassis. 

In the listening room they performed admirably with a fairly difficult load presented by a pair of B&W Nautilus 800 series speakers. 

Our Testing Process for Amplifiers (Solid State) at SkyFi:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage Kef speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
