Bottom Line:   
With my association with audio stores I have been able to preview numerous speaker and amp combinations. Of all those that I have listened to, the Quad 63 and its later varients, along with the esl 57 presents the closest approced to the original sound.

I posted a review of these speakers here, some years ago. I have since had all the panels replaced by Wayne Picguet of Orlando Florida, (who I highly recommend) this past Christmas.

My system consists of:

Grado/Decca,London/Stanton cartridges which I switch from time to time
SME arm
Linn Sondek turntable
Quad/Krell/Mark Levinson preamps and amps which I switch from time to time
Quad Tuner
Quad CD player
Meridian DAC
Alpha-Core/Pure Silver Sound cables again I switch them from time to time
Quad 63 ESL USA Monitors

It has been some years since I left my review of these speakers. Since that time I have had Wayne Picquet of Orlando Florida to replace all the panels with his panels. His panels are very close to the originals except that the coating material is a bit superior to an already excellent material, and he stretches his membrane at optimal tension. He also replaces the capacitors in the electrical system of the speaker.

The results of which were they sound like they did when new, except the highs have been extended (cymbal crashes, and brush) and the lows have been extended. I can now hear and feel low A, 27.5cps with the refurbished speakers.

My speakers sit on a suspended wood floor. (Yes I have heard them on a marble, and tile floor, they do not sound as good.) The speakers couple with the floor, and the bass sounds real. (I do not use terms like fast or tight.

The Quad 63s are placed so that one of them fires down a hall about 17 feet long from the rear side of the speaker. Therefore there is no wall from the rear of the speaker to the end of the hall. Maybe this accounts for the bass response. They do not sit on stands.

I have measured the speakers and the maximum amount of bass, (or any other frequency) occurs at the resonant frequency of the speaker, which is about 40cps. Meaning they play louder at this frequency.

The speakers measure as loud at 30cps as they do at 50cps. Therefore pipe organs which I listened to a lot, are no problem for this speaker.

It appears to have heavy bass when the tuner is tuned to the rhythm and blues stations, according to the 18 and 20 year olds that have heard them.

I do not recommend that a sub woofer be used. PM speakers are not fast enough.

Because of the extended treble I have had to switch from my 99 cent cables to decent ones which I now use.

It is my belief that these speakers come close to the original sound. The only way to judge this is to listen to live performances a lot; and then compare them to a speaker. Soundstage and Imaging are nebulous terms and do not mean much in high fidelity. It either sounds like an oboe or it does not. That is what these speakers achieve, a close approach to the original sound.

Bottom Line:   
I bought my ESL-63s about nine months ago. In my many years of audio exploration, I have owned many other speakers. During the last four years, I have had PSB Stratus Golds, Magneplanar MG 1.6QRs, Klipschorns, Thiel CS 3.6s and the Quad ESL-63s. The Quads are the only ones left in my listening room. That may say enough right there.
My two primary concerns before buying them were their supposed lack of bass and inability to play loudly. I was able to audition them before purchase and considered that they played plenty loudly enough for me. They have a lean, quick, articulate bass without exaggeration or boom. They may not go as low as some speakers, but the articulation of the bass that is there is musical, true to the timbre of the instruments and matches that of the rest of the system. My listening room is 14 x 22 ft. with 7.5 foot ceilings. I can play music louder than I am comfortable listening to it with the Quads, and their reproduction is superb.
I listen to classical music, opera, acoustic music--folk, blues, some pop, rock, soul, etc., a pretty eclectic array of program material. With small ensembles, the inner detail of the music is simply breathtaking. I can hear each instrument clearly in the mix without exaggeration or unrealistic highlighting of any instrument. In some orchestral music it is sometimes difficult to distinguish between, say, a clarinet and oboe. Not with the Quads!
The real acid test for me is reproduction of the human voice, particularly operatic voices. Over many speakers, opera singers, sopranos and tenors, sound hard and edgy, sometimes almost metallic, the sound is unbearable. I attend at least four live operas each year, and I have never heard anything like that kind of sound emanating from a singer in an opera house. The Quads handle these voices with uncanny realism. The character of different singers' voices is preserved but that artificial "hi-fi" edge is simply not there. I am so pleased to find myself no longer feeling my shoulder muscles tightening in anticipation of some unbearable screech at a climactic moment--no cringing, no "listener fatigue"--just singers!
Orchestral strings are another area where many speakers screech, The Quads produce superb strings--resiny bowing, clear, clean string timbre whether loud or soft in volume.
All the speakers I have owned were well-regarded and each had some particular strength. The Quads outperform them all, providing those aspects of speaker performance that count the most for me.
If you have been curious about them, I urge you to do your utmost to audition a pair. I heard Quad 2905s at a dealer before I bought my ESL-63s. I could never afford the 2905s and there is actually very little difference between them and the ESL-63s. Very highly recommended.

Bottom Line:   
Quad ESL63 sound very close to original sound, no coloration added and the most interesting is non fatiquing for hours of listening.

Bottom Line:   
I had many speakers in the last 5 years mostly totem, elipson, klipsh. On some occasion i got to listen to esl-57 and esl-63 and they slowly grow in me. Each time i was amazed by them. One of the best setup i ever heard was based on esl-63 with good stands in a very big basement. More i was searching for my sound, more i was interested to electrostatic speakers. In another hand i was affraid of the high cost maintnance and reliability of the quad and find some flaw on mangnepan speaker exept on very high-end ones. I finaly I found a good deal and take my chance on a recently rebuilded pair who seem to sound good in the very small seller room.

At home it was simply a revelation, any speakers i even own was simply forgeten in a couple days of listning. With position tweaking (lot of space on the back and from sidewall), rising them 14 inches and using the 16 ohms tap on my amp and I'm now in my nirvana. They certainly don't lack in bass, the mids are sweet as hell and instruments really sound like they should. All thoses years that i wanted them but was too afraid to buy a pair ...

Thoses speakers are for real music lover, not for excesive purist.

Bottom Line:   
My first pair of ESL-63 speakers were the original International Monitors, serial # 5000s. These were purchased in England years before a modified ESL-63 was sold in the USA as the US Monitor.
After 22 years, one of them developed a leaking capacitor which makes weird noises, and I replaced it with ESL-63 USA Monitors (serial # 21,000s), an upgraded version of the originals. The original ESL 63 was the best speaker ever made, especially for classical music. The US Monitor is better, being a bit more open.
These speakers are not fussy unless they are over powered. If you have pop music induced hearing loss, you won't like them.
Quads roll off from 40 Hz (which is pretty good bass unless you are a hard rock nut), and a little low base boost makes sense, but running the Quads through a crossover is not a good idea, it only makes things worse. I built my own subwoofer with its own amp that rolls off -6db between 30 and 40 Hz, and the signal is terminated at 40 Hz. That way. in only adds bass in the region where the Quads roll off without taking anything away from the Quads.
