Anthony Gallo Acoustics Nucleus Reference 3.1

These speakers created quite the strike in the 2005-2010 era due to the amazing review and innovative design.  

The particular set is the later 3.1 version with many improvements over the 3.0 version including new midrange drivers and crossover refinements.  

They throw an amazing soundstage and have tons of bass.  If you want even more you can add an outboard subwoofer amplifier taking the lower bass from a very satisfying 32Hz to an astounding 22Hz.

These are in very good shape but have an occasional scratch or ding here and there.  One of the grills has a small tear in the fabric barely noticeable.  These are overall very presentable.  

All drivers are in perfect working condition and have been fully tested.  Bass is deep and tight and the highs sparkle.  

This item available for pickup in Ridgewood, NJ or Union Square NYC (with convenient parking in the building).

NJ Residents or anyone picking up without a resale certificate will need to pay NJ Sales Tax.

Use the buy it now button and we will cover the PayPal fees.

Thanks for looking and be sure to call or text 646 852 2073 with any questions.

Reference Home Stereo Speakers for Everyone

The all-new Anthony Gallo Nucleus® Reference 3.1 loudspeaker is an improvement on a true classic. Featuring enhanced mid-range drivers, upgraded capacitors and the elimination of the tweeter switch, the Reference 3.1 brings our flagship stereo speakers to even further heights. From its unique, forward-thinking design to its patented 300° dispersion tweeter, every element of the Reference 3.1 practically screams "enthusiast." And best of all, it all comes at a price that won't break the bank.

Anthony Gallo Acoustics has shattered the price/performance ratio once again with the all-new Nucleus® Reference 3.1 loudspeaker. Reference 3.1 speakers feature several significant changes that take the performance of the award-winning Reference 3 loudspeaker to a whole new level.

The stereo performance-enhancing features of the Reference 

3.1 include:

Improved Mid-Range Drivers:
Our Reference 3.1 stereo speakers feature improved mid-range drivers which incorporate a neodymium magnet and genius design for improved efficiency, mid-range detail and transient response.

Upgraded Power Capacitors:
The Reference 3.1’s all-new metallized polypropylene capacitors offer greater dynamics and lower current.

Tweeter Switch Eliminated:
The tweeter switch has been eliminated to ensure even greater signal coherency and high-frequency purity.

The Anthony Gallo Acoustics Nucleus® Reference 3.1 speakers are a true high-end home stereo speaker. Designed with the performance- and decor-conscious audiophile in mind, the Reference 3.1 will add a timeless look to your living room and let you hear what you've been missing in all of your favorite movies and music recordings. Thanks to the Reference 3.1 speaker system's unparalleled transparency and neutrality, your favorite musical and cinematic moments come to life exactly the way they were intended to be heard.

Among the many special features that make our Reference 3.1 stereo speakers so unique is an upgraded version of our patented CDT™ tweeter, the CDT II™, as well as a hollow-cast, aluminum chassis filled with Gallo’s patented S2 technology air-density treatment. The CDT II™ and the S2 Technology are two crucial proprietary elements that meld to form an award-winning combination of stereo clarity, precision and range not found anywhere near this price point for a speaker system.

The Reference 3.1's CDTII™ tweeter is so transparent, fast and dynamic that it offers 300° horizontal dispersion, making the Reference 3.1 a versatile, powerful option for just about any room in the house. Meanwhile, the patented S2 technology actually de-couples the backwave of the driver from the air inside the enclosure. The benefits of S2 in home stereo speakers include superior low-frequency extension, improved transient response and a substantial increase in efficiency.

Our Reference 3.1 stereo speakers are uniquely equipped to demonstrate the advantages of the leading high-resolution formats: DVD audio and SACD. Very few high-end home stereo speakers, including the majority of models costing $10,000 or more, can approach, much less equal, the Reference 3.1 speaker system's extended high-frequency response, and even fewer offer \ its near omni-directional dispersion. For the ultimate in neutrality and transparency, the Reference 3.1 operates without a crossover across most of its bandwidth - from 125Hz to 35kHz.

An in-depth three-year development process was required to complete the design of these revolutionary home stereo speakers, with much of this time being invested in critical listening tests conducted by Anthony Gallo and his team of critical beta testers. True to its roots, this innovative new reference speaker system builds on the design philosophies of our original — now legendary — reference products: the Nucleus Solo and the Nucleus Reference.

The high-powered Reference 3.1 speaker is designed with style for audiophiles seeking maximum performance from their home theater speakers.

Reference 3.1 speakers are equally comfortable in either stereo or home theater configurations. The Reference 3 S.A. (subwoofer amplifier) is our 2 x 240 watt stereo amplifier which incorporates an active crossover/bass EQ option to extend the Nucleus Reference 3.1's bass response to a room-shaking 22Hz by driving the woofers' second voice coil directly. The combination of the Reference 3.1 stereo speaker and the S.A. subwoofer amplifier takes this home stereo system's unparalleled sound yet another step further, maximizing full-range performance with true stereo subwoofer bass extension from a small, unobtrusive package.

Gold-plated, all-metal binding posts ensure secure speaker wire connections, and the full-height removable grille cage with welded steel support members lends a more traditional appearance. In addition, each of your Reference 3.1 speakers undergo extensive computer quality control testing.

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 select 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 and service 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 of 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 offers outside the 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 don 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 what accessories are included such as a 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 sell 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.  

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 in the local 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.
