The Quatros
When used with an Integrated it needs to have the Preamp out
as well as the main amp input for the Hi-pass advantage.
This nicely relieves the main amp of heavy lifting with the lower frequencies.
The Quatro’s self-contained bass amps with adjustable in room
Bass Tweak takes performance dramatically to another level.
Of course, if you have a preamp and power amp this works as well.
Some Years back we hooked up a pair of Quatros to an MF Trivistor integrated that had pre-out Main in with success.
The well-written manual explains the setup procedure and downloading a
Vandertones CD on the website makes for an easy setup.
The single most overlooked task is improper High pass adjustment.
This is easily solved by setting the dip switches in the high pass to manuals
published input impedance but positively confirm it correct with a Voltmeter set to AC volts playing Vandertones Trk 27 adjust the volume of the preamp to 1 Volt AC with probes at amp or speakers + - then play Trk30.
Adjust hi pass dip switches until this reading is .707 or as close as possible, 5 percent it’s now set correctly.
After each dip adjustment, you must start again at track 27 confirming 1 V AC then trk 30 is perfect.
If purchasing a used pair of Quatros make sure you adjust all 11 pots on each speaker so they are set straight up and down 12 o’clock 6 o’clock position.
These speakers are not for the neurotic audiophile, easily overwhelmed or feebly minded scared to bust a move.
Folks that get it are the same that know achieving something this special is worth the extra effort to do it right and the rewards of music speak for itself.

((((Your integrated amp has pre out's (according to a quick Google), so you are good to go .))))
Not so fast
Bob, you have separates think about it preamp/main amp
Jazz needs to be able to put the Hi Passes in between the preamp and power amp he may not have a main in.
If Jazz is emotionally attached to his MF he can always get a normal pair of Treos. Or plan B he can also use his MF as a pre-out and try a separate amp something like a basic 275 NAD amp and do the High Pass bi-amp with Quatros and acquiring an RCA version pair of Hi Pass units selling off the XLRs that come with the Quattro deal.
Hope that clarifies

((( I don’t believe in NAD being high-end equipment. Musical Fidelity is also a dark horse for me. I was looking at Meridian but the amp I was looking at was sold too quickly for me to get a grip on it.)))
Majoring on the minors lesson learned
Jazz
When I started working at Tech Hi-Fi I walked into the showroom much like all the folks believe here.
A young lady the sales manager Mary Ellen said what are you staring at
I replied all those electronics they must all have there own sound and personality.
She gave me a quick response and said the real differences we hear in sound is the Loudspeaker and it is mostly responsible for the sound we hear.
That statement is still to this day an important lesson learned
Most preamps and amps today have little coloration and we can all debate our faves ying yang neutral etc.
Most sources today are honest low coloration and semi-affordable.
As we go up the food chain better electronics seem to just get out of the way of the music nicely.
If the loudspeaker makes the single biggest contribution, add in a decent
normal living room with natural diffusion, bookcases chairs, plants area rugs, nik naks etc and electronics that get out of the way of the music and our goals are kind of met.
The Quatros hi passed and bi-amped tuned to your room with proper set up are such a speaker that even with a cheezbox dennon 80-watt receiver with preamp out main in let alone in your opinion lowly NAD
would still impress cause it s the Speaker that matters.
We recently did a pair of Quatro CTs with an Arcam receivers pre-out to a Nad power amp until he can afford the Ayre gear.
It still had us all pinned in our chairs not wanting to leave and
that’s what it’s all about.

Please make sure if you switch amps in the system that you use Vandertones and nail the X 5s hi pass set up proper dip switches to confirmed its exact input impedance with a voltmeter as instructed in the Vandy owners manual.
It is essential to not just take for granted the amps input impedance spec as it's a good place to start most likely off and it could push the x over to 80 Hz which doesn't allow the Lightning fast Quatro driver to be at its best.

(((3 out of 4 are DACs with volume regulator, the last one is a streamer with this)))
Bleak at best.
Try and find or keep a real preamp without ICs in the path.
Audio Research Ayre Aesthetix etc
have you done the in-room compensation set up?
Have you read the manual and done tilt back?
Are your spikes / cones installed and tight?

Jazz
nothing wrong w you PRE amp
The fact you are commenting about
how anything sounds without doing the proper set up protocols
is very confusing to your audience
and yorself
and that would in return give you
half assed results you need to read the owners manual and get the spikes , spacers and parts to experience what you paid for

PH for Vandersteen 5595820324
Order a Vandersteen Quatro spike kit from Jacqueline V.
Owners Manual hard copy
it should also come with the Vishay precision screwdriver
4 black front cones 2 for each speaker
2 special back slot spikes
extra outriggers for stability
variety of washers.
if you have wood floors 6 Vandersteen floor protectors
these maintain floor protection and desired low profile.
CD Vandertones has the correct tuning frequencies
Tomic mentioned a Radio Shack( analog type) meter E bay has for calibration reasons.
if you can follow the above without any substitutions you will be on the correct path to enjoy music.
Sorry, you are expecting rocks but as you will see when you follow thru
with proper setup tilt-back in-room response adjustments, all of your prior observations will change and improve in a dramatic way.

(()(So, the total we are 4 front cones and 2 back spikes, right? )))))
Yes correct

.
Try a bar of soap or beeswax on the threads
Of course, if you got the right threads and legnth that is.
Maybe its time for the correct items above?

We just Got in the latest Quicksilver 120 WPC mono's 2 KT 150s per side
with Ayre Dac, ARC Pre in front.
Could just be what the dr ordered with the Quatro's CTs Hi Passed running 100HZ up with the feedforward message these new Quicks are sending into the tunable Quatros powered bass section sound is really growing on me ......

Zero Feedback w High passed Quatros is the blueprint for best performance many will work Ayre, Aesthetix, Atmosphere Bat, the Quicksilver new120 amps have superb transformers are Made in USA hand wired without circuit boards, run cool 4395 w Russian KT 150s You get what you pay for.
Manley hi feedback at their best controlling multiple woofers, which you don't have.
You need a fineness amp with Zero feedback 100 HZ on up a pre-owned Ayre V5 zero feedback would be sweeter and alive on Top and better than tube amps with Hi feedback and dumbo dark transformers.

HP units are worth keeping they will sound just a bit cleaner then built ins
If you Just use the Vandersteen XLR Battery Bias HP filters switched to 3/5 into the top Atlas XLR inputs you may not need anything else anymore.

(((Atlas stereo and mono both have serious low end vise like control, probably worth looking at vandertones again just to see....
best)))
Yes agree, solid advice........
With Aesthetix Atlas or when changing from any amp make sure you reset the XLR high Pass Dip Switches to corresponding input impedance adjust all back to open and then set dip 3 / 5 closed for Aesthetix's proper 100 HZ x over setting.

(((I also hope there is a section in the Atlas manual for setting the HPF for Vandees)))
When hooking up the Atlas both channels are a mirror image of each other.
Speaker binding posts Positive and Negative are in reversed positions on the back of amp look closely at what you are doing with + - and you will be fine.
As for the interconnects if you are going to use the Atlas internal High Pass install your interconnects to the lower available inputs, keeping the amp in mute
touching the right side of the black rectangle display window located on front center of amp allows selecting on proper inputs chose accordingly input 2 either SE for RCA or input 2 Bal XLR and then Set Crossover to 100 by adjusting display window and lock and your set.

apples to apples
not oranges
had you both RCA and XLR external types
you would of seen what I mean
the Atlas run in XLR will sound best because it's a true Balanced amp.
enjoy
