Never heard them, but design wise they seem like they are doing everything right.

His little sphere speakers I considered to be ideal design I wanted to copy when I first got into speaker building some 15-20 years ago.

I bet they sound amazing.

They are a solid 47 pounds each....and don't let the size fool you. They are prodigiously dynamic!  They just need a Tube Amp with Balls to drive them.  How about the ZMA.....coming in soon-will do!

Anthony Gallo Acoustics 3.1

I bought them LR! They are in mint condition. New, they sold for $3000.00. I got them for $1500.00. Plus, I got the 4" Mapleshade platforms and Mapleshade Brass Feet for $500.00-see Link ($900.00 new from Mapleshade). So, a nice tidy $1900.00 in savings. All mint, and playing like the day they were new.

Currently, I have them mounted with their original Plinth and Feet from the factory. Josh/he, had switched out the Mapleshade Platforms to test as equipment bases. I will put the Mapleshades back on soon.

Impressions at Josh's House were nice. He had a Vincent Integrated (Tube pre/Solid State Hybrid), with Vincent CD Player. Even though it had that Solid State edge & the Room was not treated.....the 3.1's are musical. The Vincent is not to shabby. But, certainly not my Rig.

So, I get them home...frigin'  -3 degree's out....but worth the 42 miles each way!
Dont' cha know...the SE84CS can drive them. Now, within reason...I don't have the Mapleshade Plinths on yet or positioned the absolute best yet...but the imaging and soundstage and what I heard of the dynamics at Josh's....I am glad I bought them. The ZMA will deliver the goods into these guys.

Playing the 3.1's right now within reason for the SE84CS....reconfirms for me how my other two pair....that are a little more efficient....can play louder and more dynamic-with tone/truth of timbre & air only Decware can provide. Plus my Kimber Select with Decware and the Speakers-now including the 3.1's=matters. So, I look forward to driving them with the ZMA too. However, the Gallo 3.1's, I am pretty sure, I can make them completely disappear as advertised with the juice they need from the ZMA.  

I am very pleased! Plus, to get the Mapleshade Plinths and Brass Feet!
Stone is Toned!  
PS-they came with the hardware to mount the Mapleshade Plinths, original boxes with encapsulated foam and the over top grills-mint.

Oh, why did he sell them? He has a pair of Canton's he bought...and the wife made him choose-it was obvious (she was around).  Oh, it is good to date....I like being divorced! Now, how to break it to my current girlfriend it is over....hehe.

U bet Beowulf.

I am doing some late night Listening...just me in the house...so I can turn it up if I like.

These Speaker's are an achievement. I don't know how the 3.5's could be much better. These 3.1's are seemless, I better placed them...and once the SE84CS was warmed up....it is just locked in at 68 -72db SPL per my meter. I have the deepest soundstage I've ever had....the Speed?.......incredible with clarity.  More dynamics with SPL to be had with the ZMA I know. But, I just had to put in word now, at 1:09 am how good these 3.1's are. The Reviews ain't bullshit.    

Neodymium magnet with an under-hung design...ain't no BS.  -S

The levels of microdynamics of these Speakers, has me with a Cheshire Cat Grin on my face....that I can't wipe off. This, at 68 to 76db SPL too!

I just found a nice tweak for my Gallo's:
http://www.10audio.com/gallo_ref3-1.htm
"I did not appreciate the noise from the SA amplifier’s cooling fan. The air intake is on the front panel, and the fan cycles on and off at regular intervals, a few minutes to each cycle. This soon became distracting, so I rocked the power switch and turned off the SA amplifier. On the next cut it was very apparent that the tight, detailed bass remained, but the bass power was diminished overall. There is a pattern here. The bass was nice and tight but weak with too much resistance (a turned off amplifier) across the subwoofer terminals, and relatively slow and loose with too little resistance (no connection) across the terminals. Hmmmm. Maybe if I adjusted this resistance to some optimal value, I could realize the very worthwhile benefits of the SA amplifier but without its penalties and added complexity. I had not been drinking on this particular evening.

JerryS' Gallo Resistor Tweak - 15 Ohms

Out came the big bag-o-resistors from my bygone speaker building experiments. I disconnected the SA amplifier and tried different resistors across the "Sub In" terminals with values ranging from 1 Ohm to 50 Ohms. This trial-and-error process ended when  15 ohm, 5 watt (or greater) wire wound resistors were installed and both the bass resolution and power locked in. Not just a good compromise:  ideal. The 15 Ohm resistors have remained installed ever since and I have had no desire to either reinstall the SA amp or to revisit this issue. With this very simple and inexpensive tweak, the speakers “speak” with one voice from low bass to beyond the range of my hearing.

I have mentioned this in other reviews, but it is relevant considering the previous discussion. The loudspeaker and the listening room must be considered partners in the “bass system”. A speaker that provides excellent bass in one room may not work nearly as well in a room of different size or materials. I repeat this here because if you listen to these speakers and have the same impression of the bass character that I do, then the resistor tweak is definitely worth a try. If your room is very different and you love the bass of either the un-resistored speaker or with the SA amp, I will not be one bit surprised".
