New Owner Initial Impressions for Prospective New Owners
DISCLAIMER
I am not affiliated with any of the manufacturers products mentioned. I am just a music lover and have been since I was a very young boy. Music is very important to me and I listen for hours on every day when possible. This review is my unbiased opinion, my impressions on these speakers having owned them for four months. I am probably about half way between initial impressions and being able to do a detailed review at this point. It is not a comparison between the Quad 57 and other ESL, dynamic or any other speakers although I make some references to others. Not sure why I waited to so long to try out a pair of these speakers. If I had this information four months ago I may have made a few changes in the way I bought my pair. More about this in the speaker condition section. For this reason my words here are for the sole purpose of hopefully helping those of you that are thinking of acquiring a pair to give you “more information”. I am not a veteran or expert on these speakers, and I am learning more about them with every listening session. But recognize that I also have other speakers, that I do listen to every week in different 3 systems, that are located in two different towns.
Rebuilt Quad ESL 57 Panels – Wayne Piquet aka (PK) Model
INTRODUCTION
I am amazed no audiogon reviews on these 50 year old technology speakers that everyone talks so much about and uses so much so even today. To say they are a legend is totally wrong since they are anything but. Legends are myths, not real stories, something from the past. These 57’s are well-known, celebrated, prominent and used today as much as in the past. Yes they are famous and I think people get caught up in this when they bring them home expecting too much. These Quad 57’s are no different than other speakers in that they have strengths and weaknesses, but in my years of being a music lover they have struck a chord with me.
Of the speakers I have had and currently own these 57’s are one of the few that don’t need quite a bit of current to get them going to sound good. They also sound full at 80 db. Once you’ve heard your favorite singers voice’s on them a few times you will be hooked but not even know it. You will know it when you hear the same songs after some time on another speaker, something will be missing. So you go back to the 57 and sure enough there is that sound again. That effortless velvety midrange bloom. Its very addictive with the right music.
“CASUAL VERSUS CRITICAL LISTENING”
I define casual listening as enjoying the music itself for what it is, and how it is revealed on a specific speaker. Critical listening is listening for specific things like PRAT, bass tightness, transparency, high frequency roll off, soundstage (how wide / deep), transitions between all of these.
The 57’s I feel reproduce an excellent pin point soundstage, but I feel they are for me for listening to the “music” and not about going crazy wondering whether something sounds right or wrong in your system. In other words they are for normal volume casual listening and not critical listening. The 57’s sound great as they are - for what they are. I read somewhere that someone said they are like a “summer breeze” – that is very accurate I think. Natalie Merchant, Norah Jones, Jazz or Classical can sound to me like a “summer breeze”. AC/DC, Pink Floyd, Bruce Springsteen… maybe not. Well maybe one of Bruce’s ballads.
Even my teenage (IPOD / B&W Zeppelin RAP Music bass heavy) loving son figured out that there was something special about these speakers and appreciates their look and sound, and commented on them. That’s never happened before. When the day comes and the speakers get doled out he said “he wants these”. On the other end a contractor I had working in a room nearby during the winter thought they were really old room heaters. Little did he know what these 50 year old heaters cost!
FREQUENCY RESPONSE – Additional Subs and Tweeters
I have read and talked to people that have added a sub and or external tweeters to them. The person I bought mine from was using both a sub and the extra tweeters with them. I asked that they be disconnected for the audition. My personal opinion on this in the short time I have owned them. I believe if you have got to the stage where you are adding subs or tweeters to resolve any shortcomings to Quad 57’s, you are now doing critical listening, not casual listening. I also predict that you WILL end up selling them, because their shortcomings have now outweighed to YOU, their main advantage, the best midrange I have ever heard.
The Quad 57 bass and tweeter panel material is very thin and vibrates quickly. This is the reason the music comes out so fast. Other speakers sound slow by comparison. Musicians fingers on their instruments sound quicker like the picking of an acoustic guitar. They are faster than my Acoustat ESL. But then the Acoustats have a thicker panel material, are designed differently, and can take a lot of abuse. Much higher SPL’s. I have also been told (but have not heard in my room) that Martin Logan (not hybrid ESL) tend to be in between a Quad 57 and Acoustat in speed. Maybe others with experience here can chime in on this and confirm or not.
So how do you propose to add a sub or a tweeter to this quickness and get it to integrate properly? It will be a challenge. My opinion only is don’t bother and enjoy them for what they do well. But audiophiles are a rare stubborn breed and will keep doing it. Remember my prediction above.
I feel they lack nothing in the High Frequency (HF). Its all there, but its a delicate HF and non-fatiquing. People that add tweeters could be compensating for:
1) Bad tweeter panel – or at least not fully 100%. The tweeter panel is the one that gets damaged first when overdriven.
2) Possible Amp/Preamp/Source problems.
3) What about dirty ears – time to get that wax cleaned out.
4) Old or bad ears – HF is the first to go right. When is the last time you had your hearing checked. Women also hear better than men. So get the opinion of a female on them if you are a male.
Are the PK rebuilt panels that much better than stock 57’s ? Maybe someone with experience comparing the two (Stock 57 versus PK 57 rebuilds) can provide comment on this ?
Adding a sub to them? Again, are you sure the bass panel is 100% functional. Their bass sounds full at low volumes. Remember the summer breeze comment. Turning them up louder does not make the bass go lower. I am used to playing my music fairly loud and turning it up 90 – 95 + db with peaks well above 100db. These speakers changed my habits regarding that. They sound very satisfactory and full at 80-85 db.
PLACEMENT
Their ESL directional sound nature means placement is important and the sweet spot much smaller than with dynamic speakers. Turn your head and the image moves. Hence the term “head in a vice” in reviews. Mine are out in the room 7 feet from the back wall and I am getting 40 hz out of them. There is 5 feet from the inside edge of one speaker to the other. The sound stage in my room goes from the front wall to the actual speaker so is 7 feet deep. They were very easy to place as long as you can move them out into the room. I find with all my Planar, and Electrostat speakers, that being dipole (the sound comes out from the front and back) you need to give them “lots” of space behind, for the back wave to work and achieve good bass. And think about it, how many instruments go below 40 hz. A few but not that many. Clean tight full 40 hz bass, not room shaking bass.
BEING CAREFUL WITH WATTAGE
I was warned you need to be careful with the wattage. The very thin panels that provide that fast sound can also be damaged very easily. If you are not able to control yourself and like to crank it up – these speakers are not for you. You WILL damage them and require the panels to be rebuilt. Reports say they they will play at 100db. I have not tested this and don’t feel a need to. Remember that music playing at 80-85 db on average can have peaks that are much higher. Studies have shown you can listen all day without hearing damage at 80db. Above that and you need to be careful.
I have tried a couple different amp/pre amp combo’s. I have used them with an Audible Illusions 3a Tube Pre Amp and a 100 watt Music Reference RM9 Tube Amp – being very careful with the gain controls. Wonderful room filling sound. Recently I started listening to them through a same era mint condition SS Quad Amp/Pre Amp, maybe a bit nostalgic, but these Quad Amps and Preamps are readily available for sale and trade. I had them checked out to ensure they were in spec. I then put resistors in the 100 wpc Amp to limit its output and keep the 57’s from getting damaged. So now these Quad 57 speakers, 405 amp and 303 preamp that I am currently listening to, are older than me, and I enjoy them immensely. That set the bar for “Vintage” for me.
TALKING WITH OTHER OWNERS /Speaker Condition
Everyone I have talked to that has had them as their ONLY speaker have all said one of two things. 1) They love them and have had them for many, many years and would never sell them, or, 2) They sold them, for whatever reason, but they have all said they would have kept them if they were able to have more than one speaker and / or the room to store them and place them properly in the room.
There are many around in various condition. Originals in good condition, some in need of repair, and rebuilt models. Be wary of sellers – Do not buy unseen unless the seller is trusted. You need to ensure the panels are functional and will play at an SPL level that satisfies you when auditioning. If the owner won’t play them at the level you want – he/she is either covering up a problem or they will not play at the SPL you are looking for and are not the speakers for you. Check so see if the speaker connections and EHT power supply sections have been updated. One of my speakers has developed some low background noise in the EHT when it is really humid out. It doesn’t affect the sound and can only be heard when no music is playing but it is annoying. I live in the Great Lakes area of North America - summers are very humid. Consider a climate controlled room for them – this is an important point.
There are many people/places that fix and rebuild them. I am glad I went the route of finding a fresh pair that had already been rebuilt in the last couple of years, but again my EHT power modules need replacing. Easy enough to do by the DIY person but if you are not such a person look for a pair that has had all the work done already – panels, speaker connections and power supplies. I really wonder how many people that have bought and then sold them had a pair with something wrong with them. Problem panels will not play as loud, will not sound right, and will need more current since electricity being delivered is lost on possible leakages in the circuit.
ADMISSION
OK - I admit – I DO need other speakers as well that do higher SPL’s, lower Hz…when listening to artists such as Springsteen, Pink Floyd, Genesis, Roxy Music, etc… These are groups I grew up listening to at home and at concerts. I can’t listen to Springsteen’s “Darkness on the Edge of Town”, PF “The Wall”, Roxy Music “Avalon” or Tears for Fears “Seeds of Love” as just a few samples, unless they are at least 90 db average with much higher peaks. These are all actual concert setting listening sessions for me for a couple of hours.
But once that fix is done, I now clearly miss the Quad 57’s for regular casual listening again to artists like Natalie Merchant, Norah Jones, Jazz, Classical, Sarah McLachlan, Blue Rodeo. Now the venue for me because of that midrange is intimate and they are on stage close to me, playing for me in a nightclub. Those voices in that midrange, they sound personal now. That is what is magic about the 57’s to me.
I really look forward to both of the above type listening sessions. A big reason I have multiple speakers. Nothing changes the sound more than different speakers. If you are the type that enjoys multiple speakers time to add a Quad 57 in there ! I think everyone in this hobby should have a go at these speakers at least once to hear why they are still so popular.
FINALLY TWEAKS
A 2 x 4 piece of wood under the stock rear leg pointing the speaker down - more at you, actually raises the sound stage.
I have found some Arcici stands and have raised them just recently so that the middle of the tweeter panel is at my ears in the listening position. It’s too early on but I have found the bass is not lost in any way being higher up. The soundstage seemed about the same level with my ears in my room but they do seem to fill the room with sound easier. They also do look more modern on the stands. I will provide more information on comparison regular wood legs versus Arcici stands once I have had more time to listen.
I hope this information helps those thinking of acquiring these great speakers which is the main reason I posted this here in the review section. So many threads and posts in Audiogon. I am also hoping selfishly that some of the Quad 57 veterans will chime in on tips and advice for me and others here. I’m all ears.
