Audio Sculpture Equilibre 

This is a fixed price listing please don’t email any offers.  

Currently wired for 120V but can be switched to 220V    

This is super rare and amazing amplifier from France.  Till this one arrived, we hadn’t hear of this brand or model.  Searching the internet yields very little additional information but those that have had the pleasure of hearing one are raving about it.  Subsequent models were made by Audio Aero. 

While its is rated at 60W of pure class A output it performs more like a 100W amplifier.  The unique tube combination is not only rare but absolutely genius.  

This amp has KT99 (pentode) & EL34 (triode) output tubes tied together for both SLAM and mid-range sweetness.  This is brilliant, how come nobody else is touting this?  I suspect its largely because of the extra cost providing twice as many tubes while not increasing the power.  

Whatever the reason, it works like magic.  This amp is capable of rocking our Martin Logan CLS speakers without breaking sweat.   We’ve had other named 150W amps struggle to keep up in the past but not this beauty. 

Many compare this build quality to Jadis and I would agree.  Component selection and attention the detail is top notch.  The heavy transformers put the total weight at over 80lbs.

Condition is fantastic and there are no signs of use or abuse.  Everything is clean and perfect.   I can’t imagine anyone being disappointed. 

The unit was not only bench tested but also spent a few weeks in our listening room where it performed flawlessly with all sorts of speakers from planar to electrostatic.

Skyfi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of select high end audio equipment.  We only buy equipment the we admire and are passionate about. No mid-fi, no gimmicks, and no junk. 

Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. If it does not meet or exceed the original manufactures specifications, it will not be sold.  We are very selective about the equipment we purchase, focusing on mostly analog, high-build quality, American, and European built units.

Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support.  If you are local and are looking for any new equipment for the above-mentioned manufacturers, please drop us a line as we can arrange both sales and professional installation in the tri-state area


We do not accept or review any offers that do not go through the official Audiogon system. We have too many items for sale and its nearly impossible to keep track of offers outside of the official system. Please don’t message, email, or text any offers. 

If you do not see a “Make an Offer” button, it means we are not considering any offers on that item.   


We prefer working through PayPal, which allows you to use a credit card or bank transfer. We do not charge extra for any payment fees if you purchase the item at the asking price.  You can also send us a personal check (which will need to clear before shipping), certified check, money order, or wire transfer. International clients without access to PayPal should use a bank wire transfer. 

If you are picking up an item, we do not accept PayPal.  You must pay in person with cash, certified or bank check, or wire transfer.  If you make a PayPal payment and are picking up the item, it will be returned. 


We accept trade-ins of equal or lesser value under certain conditions.  Simply ask and let us know the exact model, condition, and the accessories that are included.  Such as the original box, remote, manual, etc.  We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. and will typically pass on displays, projectors, receivers, dated processors, and mid-fi equipment of any type.  We will offer a fair value for your equipment, but keep in mind we are running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment.  If you are looking for top dollar we suggest attempting to sell it directly to an end user on your own.

SELL US YOUR GEAR (Working or Broken)

We will also purchase your used or broken gear and arrange pickup if you are in our local market.  Just drop us a note for a quote but be sure to include the condition and what is included. 


We are currently operating from a residence in Ridgewood, NJ.  You are welcome to make an appointment if there is a piece of equipment you would like to see in operation before or after purchase.  We have a well-equipped, dedicated listening room with tons of equipment of all makes and models.  We are not a store, so please don’t make an appointment if you are just curious as to how a speaker or piece of equipment sounds.  In essence, no tire kickers please.

If you are in NYC and cannot make it out to Ridgewood, we can arrange pickup in Union Square (14th Street) after the purchase.   You can call or text 646.852.2073 with any questions or to schedule an appointment.  We can also arrange to install, calibrate, and tune the gear in your listening room if you are local to the area.  This is super useful when purchasing large speakers or heavy amplifiers.  It is also great for ensuring your new turntable is setup correctly in its final resting place.  

Thanks for looking and please send us your email address if you would like to receive a list of the equipment we receive from time to time.  We promise not to bombard you with junk email.
