Review: Sony SS-M7aes Speaker


Category: Speakers

Speakers are by far the most subjective piece in the average person's system and the one that tends to create the most excitement, whether positive or negative.
A multitude of evils can be overcome with the right speakers or every fault in the system can be made glaringly obvious. Let the mudslinging begin!
Several years ago I happened to wander into the local audio emporium to see what was new, exciting and due to my budget constraints, affordable. I glanced around at the latest offerings from B&W, Magnapan, and others of their types. Nothing caught my eye but one of their eager young salesmen felt the responsibility to show me the item they were currently trying to unload on unsuspecting customers. Of all things, a Sony speaker!
Being the savvy shopper that I am I would have no part of it. Everyone knows Sony does not make good equipment especially speakers.
Several years later I was in another store and the owner tried the same thing with the same speakers. On this occasion I must have had more time because I listened to his pitch and actually listened to the speakers. Much to my surprise they did not sound anywhere near as bad as I thought they would.
The salesman explained that Sony hired a reputable American speaker designer, gave him the checkbook, and told him not to come back till the job was done.
One of the models he developed was the SS-M7es. It was the first model released but in the middle of what would eventually become a three-model set of speakers. The SS-M3 was a two-way bookshelf speaker, and the SS-M9es was a floor standing four (or later a five driver) model which would eventually end up on Stereophile's class A list of recommended components.
The SS-M7es is a three way, three driver, stand-mounted speaker. None of the cabinet walls are parallel which greatly reduces the possibility of standing waves within the cabinet. The cabinet is made of 1" MDF and comes in many finishes.
The crossover is a third order Thiel type. The drivers were made for Sony but I do not know where they came from or who made them. The speakers themselves are made in the USA.
The speakers come with two sets of binding posts to facilitate bi-wiring, or bi-amping. I would like to see better metal binding posts instead of the plastic which comes stock.
The owner of the store offered to let me take them home and listen. Since no one else was in the store at the moment and no one would ever know I was going to listen to Sony speakers I took him up on the offer. How bad could they be, I wondered to myself.
I used them in place of the Focus .7's I had bought about five years earlier. The Focus impressed me with their overall tone and soundstaging. Alas I don't think the Canadian Company is still around.
I did not expect the Sony’s to compare very well with the Focus speakers, but since installing the Sony’s they have not been out of my system. Everything the Focus speakers did well, the Sony’s did better. Overall tone was as good as what I had been hearing and the soundstage was much tighter and better defined. The treble was audible to my ears to about 14 kHz, but Sony claim’s to go all the way to 20 kHz. Not that it matters to be since I can’t hear it anyway.
When playing LPs I have noticed on many occasions that there was sound coming from outside the spread of the speakers. The soundstage is much wider than the speaker placement. I know some think this is impossible, but I have heard it, as have others. The soundstage is also taller than the speakers are. One of the most pleasant improvements was the front-to-back depth of the soundstage. There is a palpable image presented in front of the listener. Instruments are tightly defined and located within that soundstage. Sound emanates from both the front of the speakers and from behind them.
I have listened to everything from heavy metal to chamber music with these speakers and they handle everything well. They are not perfect, the listener will not be fooled into thinking there is a flute player in the room, but nothing else will do that either. Natural timbre is very important to me, and the Sony’s do it well, but I know it is just recorded music. The biggest factor in musical enjoyment is still the listener’s imagination, not the electronics or speakers!
As I have replaced pieces in my system the Sony’s have continued to improve. I am on my third amp. When I bought the speakers I had a Forte amp, I sold it to buy an Aragon 8008st, and now am in the process of buying a Krell FPB 200. I also have had three pre-amps. Since buying the SS-M7es. I began with a Counterpoint SA 5.1, which I replaced with an Aragon. After a few weeks with the Aragon I bought the first of two Krell pre-amps. I am now using the KRC 2. I am only now thinking that it might be time to look at something better. I have listened to many friends system with much more expensive speakers and still did not think their speakers were better.
The only real fault to point out was also true of both speakers. Using the test CDs I own I was only able to discern bass down to about 45-50 Hz. Neither of the speakers will reproduce the deepest bass.
As I listen it is hard to fault these speakers. The worst attribute they possess is the anchor of the Sony label. People have decided that they cannot build a good speaker. I know from experience that these speakers would be very popular if it were not for that label. No one who has heard the speakers has said anything bad about them. The fact of the missing low bass registers has been mentioned, not as a complaint as much as an observation. Audiophiles have to say something you know.
If you want to buy a great sounding set of used speakers for a little cash investment you owe it to yourself to listen to these speakers. A buyer can spend a lot more money and not get a better speaker. Take the Sony label off of them and lie to your friends (if you must), they will be impressed by the sound.
These speakers might truly be one of the best bargains in Hi-end audio.

Hey, aNrchy where can I buy the Sonys and how much should I expect to pay for them? I thought about "lothar's", but the proper enclosures are too large for my room. Thanks for sharing the review with us.

If you are really interested in the Sony's I have sen them here on AudiogoN. I have seen them priced anywhere from $350-500 which is obviously less than I paid for mine. At full retail they are a good deal, at the price I just mentioned they are a STEAL!
Good luck.
Nrchy and following posties:

Ah, there is nothing like the unrequieted longing for a lost love. I have waded through a plethora of tranducers in my search for my own slice of audio nirvana. When I came upon the SS-M7s I was forever smitten. I received a great deal on them because of the aformentioned Sony badging and consequent lack of sales. The system I put together with these beautiful works of sonic (and visual) art (Adcom GCD-575 cd player, Audio Alchemy DLC preamp, circa 1978 Marantz 256wpc amplifier - sorry, I cannot remember the model number, Sunfire True subwoofer) created such a wonderful synergy that my (sometimes) obsessive desire to upgrade was cured forever (or so I thought - but hey, a cable here and tweak there never hurt anybody, right?). Unfortunately I got married and the lack of WAF forced me to sell, though I did win a pair of Wilson CUB IIs from Audiorevolution.com (she liked those). Now we are divorced (don't mess with my system!) the CUBs are gone (a fine speaker but they demanded electronics I could never afford) and I have been saving my sheckles for a return to Xanadu. I found a person selling a new pair, complete with deicated stands (very rare) on Ebay for $800. Come on tax return!

Good luck to you Nrchy (yes, it is a bit anarchistic to purchase an audio component based soley on performance and eschew lables - wierd, eh?) and all owners of this rarified product.

Cheers and a great thread!
Thanks for the thorough discussion. I've always admired the design of these speakers, though I can't remember ever hearing them, but I did see them in person. A while ago you were talking about looking for new speakers, I thought - any update?
Zaikesman, I have taken a fair amount of flak from fellow AudiogoNers, but I have to say they still sound very good. I know they are not a great speaker. They will never compete with a pair of Watt Puppies or Soundlabs, but they cannot be beat for $1000 more than the retail price. For a person looking to buy the less expensive Theils, or any number of good, inexpensive speakers, the Sony's are a steal.

Every time I add a new piece of gear or cable, the Sony's sound even better. I just bought some of the new (and much cheaper than in the past) Purist interconnects and speaker cables. They are still breaking in, but they already sound very good, or should I say the system sounds better than it did with the former cables.

I know that based on the value of my system the Sony's are disproportionally cheap (retail of the electronics is about $30,000, and the speakers are about $1500 new) but I still sit back and listen with a big stupid grin on my face.

I am saving to buy a new pair of speakers this summer. Hopefully I will be able to get a pair of Wilson's or Soundlab's, but until than I don't feel terribly short-changed by my Sony speakers.
