Gallo Reference 3.5 Speakers. Now Looking For Amp


Recently purchased a pair of Gallo 3.5's. I have been reading Audiogon for years, but this is my first question. Your assistance and expertise as to which amplifiers should be considered with these speakers would be greatly appreciated.

These speakers were selected to replace my B&W 805s speakers due to the fact that my equipment is going into a small music room (11'x13') where there is no dedicated seating for the purpose of listening to music. There is a drum set, 2 keyboards, 2 guitar positions, stereo rack flanked by speakers and a plasma tv on the wall above the stereo system. The center of the room is open as the music equipment has been placed more towards the walls. The 805s just don't have enough clarity and instrument separation when listening to them from one of the music positions. For the most part, the only time the stereo system is on is when I am playing one of the instruments.

Speaker positioning is limited in this current layout. Hopefully, a larger room will happen in the next few years but for now, this is it. If the room size does change, I will design a dedicated listening space in the new room. This is the reason for buying the best equipment possible for now (budget permitting). If the right pieces are added now, they won't necessarily have to be changed later.

I understand that these speakers do require some power to push them. "Preowned equipment" for the amplifier would be "preferred". Budget for the amplifier would probably max out at the $4,000-$4,500 range, but do not have to spend that much if something more economical does a great job. Musical style ranges from Blues, 70's-80's Rock, Santana, 'especially' acoustic guitar, etc... (not a fan of classical, but can appreciate it).

My current amplifier that will be replaced is a Rotel 1080. No problems with it, just thought it would be a good time to upgrade. I don't mind spending the money as long as it makes a noticeable difference!!!!!! Just trying to think long term and I do appreciate quality equipment.

Ihave found the Passlabs 250.5, as well as the excellent Plinius 301
Both are the best that I have ever heard.
I was driving my Reference 3.5's with a Bryston 14 B SST and tried a used Axiom A-1400-8 which is an 8 ch class D. I also decided to go 5.1 surround. With the Axiom I was using a low pass filter set at 55 Hz to drive the second voice coils of the Reference 3.5's. This was the most amazing sound I have ever heard. The Axiom sounded much better than the Bryston did in this configuration. The problem I was having was a mechanical relay noise from the one unused channel. I was using 2 ch rear, 2ch front main, 2 ch second voice coil and one ch centre. That left one unused and the clicking relay drove me crazy and I sold the amp. I'm kicking my self now, because that was one very sweet combination. The Axiom amp is very quick, detailed and extremely powerful, it also had the best high end of any amp I've owned. It was very detailed but not at all bright or sibilant. The new Axiom is available in 2, 3, 4, 5, 6, 7, or 8 channels. I will be getting one soon. I bought an EMOTIVA XPA-5 to get me by for now, but it has a very hot top end with these speakers and is somewhat sibilant.
I am using mine with Consonsance cyber 845 & Gallo SA.
Those speakers disappear completely when I am playing well recorded music from my modified MacMINI server.
The bass is beautiful,tight, deep and tune full.
The tonal range is natural and captivating.
The only system more holographic that I have heard was made by MBL.
The 3.5 replaced a 3.1 set with MapleShade stands.
I tried the 3.5 with the stands but did not like having the musicians playing above the normal plane.
I am using my system in a Roomtune treated dedicated listening room.
I quit watching the boob tube for months now.
I listen to music from around the world from Boine, the artist from the Lapland to the ECM artist and Giles Coquard,Hans Theesink the dutch blues singer.
Update. I went back to the Axiom class D….I bought the new version of the Axiom, the ADA-1500 in a 4ch version. 2ch to drive the mains and 2 thru a low pass filter from 55 Hz down. No relay noise! This amp is a perfect match for the Gallo 3.5's. Detailed, but smooth and no sibilance. Very life like Mids and awesome bass with very good control. This is the most realistic sounding system I've heard yet.

I wonder where you are at with your system from 2013?
I started my passion with hi-fi in the mid 70's. I had gear like b&o, luxman amps, nakamichi, teac decks, Akai reel to reel, Kef 103.2, later 105.4 speakers, thoren table, formula 4 arm and Shure mark V Cartridge, Stax headphone.
Then I left home to come to Canada. Never had a chance to get back into it. I missed it a lot. Used to have 4-500 LPs, spent 10 minutes to pick a record, another 5 minutes to clean and set it up. Ran to my spot to listen for a few minutes. Then all over again lol. 
By chance I bought a pair of AG 3.5 in 2014, a set of AG reference surround and a centre. I came across with this article about how good emotiva was. I bought XPA-5 and the Sherbourn PT 7030 7 channel pre/pro. Thought would go with the digital route with lossless format (I am a complete rookie after 40 years).
Problems started - Sherbourn didn't come with a manual. I read something like "if u need a manual u better get a professional to do everything for you ..." At that point I thought maybe I should have invested in a used bema m3 lol. My space in the basement is far from OK much less good, "sorta" rectangular shape with hall way to laundry room on one side,  stairwell going up on the other side, a small bedroom on the third side with gun and wine cabinets in front of it. basically it's a half finished basement with concrete floor, no ceiling but all dry walled.
I use monoprice XLR connect cable, 12 guage speaker wires. I hooked everything up without any sonic adjustment. Back in the days we always played everything FLAT. Even if I had to I wouldn't know how to play around with all this high tech buttons and switches lol. 
A few days later I finally got some sound. It was OK but far from my old system 40 years ago much less the SUPERB QUALITY I was led to believe. I knew my inability and lack of modern techniques were most of my problems. I could have bought the KEF R900 and the Marantz pre/pro from a neighbourhood stereo shop for $9000. Now I spent more money and didn't know how to set it up. The 3.5 were barely delivering any bass. For a quick fix, I bought a 800 watt mirage Sub to lie to my ears. I lost interest, gave up and walked away for 3 years. 
Lately I am downstairs messing with it again. Took me a few days to re-learn how to turn everything on again. I would hate to admit a defeat to my passion and sell everything for cheap. Or I should give it another shot.
First, I gotta re-learn new gear, concepts, operating procedures, pricing etc. I hung out in high end stereo shops, helped them move gear around for demo, in return these old guys showed me stuff. Now I am learning online. Can't believe everything we read, right? I am reading up how to treat my space. Owens Corning 703 are no where to be found in Canada OUCH!!!! A couple of sites offer to do it for $5000-$8000. WOW, REALLY???
Someone suggested AG SA amp. First, can't find it. Second, other gurus said just feed THE 3.5's with a lot of clean power and forget about the sub amp.
Another problem, I am running a 5-channel power amp with a 7-channel pre. There is hardly any surround coming out of my back AG Reference Surround.  Damn, my head is spinning now lol. 
Am i missing a few steps in hooking up therefore getting inferior sound? I prefer no extra colouration, just the way it was recorded. Should I continue with emotiva big power amps for the main and keep the XPA-5 for surround? Or should I get something like a Spectron, or your Axiom? Big amp for speaker main in? Or another amp to feed the second coil? 
I just got married last year, for the first time, and started a new business 2 months ago, I would be more cautious this time around in buying gear.$1000-$3000 is automatic. Over that I will have to think about it. I don't included gear. I also wanna remodel my basement to turn it into a listening room. That should improve a of right there.
Any advice, from anybody, would be appreciated. I feel like Carlos santana asking for help to plug in a guitar lol.
