Merlin VMS versus VMPS RM-40 versus Proac 3.8


Has anyone had a chance to listen and compare any of these speakers? Unfortunately there are not dealers nearby, so any input you can give is much appreciated. They will probably be paired with Pass amplification and Tact 2.0 room correction used as a pre.

Thanks.

Geeeeez guys, reeelax! Here's some perspective for everyone on both sides of this argument:

Brian Cheney has developed an affordable full range tower speaker knock-off that's sort of a cross between a dunlavy SC-IVa and a Genesis/Infinity ribbon tower that has many of the same dynamic, effortless and integrated sound qualities that these ultra expensive speakers are known for (with even better low end bass and power than the $8000+, now out of business SC-IVa). This is what the RM-40 is IMHO. He managed to pull this feat off by sourcing incredibly inexpensive ribbons from China that are 85% of the performance of the ultra expensive offerings (at less than 20% the cost per unit). His woofer tooling and economy of scale most likely allowed him to also source in his custom woofers at a very reasonable price too. With some decent first order crossovers these speakers came together to produce a wonderful sound that just doesn't sound cheap by any means and actually makes you wonder show the hell he did it with such inexpensive drivers. Driver technology just doesn't cost what it used to. More importantly, the differenced between excellent designed cheap drivers and ultra cost no object stat of the art drivers is closer than it has ever been in history. There is a difference, but it can be carefully masked by the talents of an excellent speaker designer like Brian. Could Brian's speaker be more detailed, more refined and better sounding with top of the drivers and rock solid cabinetry? Absolutely! The point is that it would cost something like $25k+ to do it that way and the differences would be pretty small for the 500% increase in cost. I congratulate Brian for bringing us some of the sonic qualities that you only could get for stupid money just a few years ago.

Bobby (of Merlin) went the entire other direction. He used top of the line, cost no object drivers in a cabinet that was also near the top in terms of construction. (This is why the VSM costs so much, yet it only has two drivers.) In all actuality, this speaker should sound good! It uses nothing but the best of the best parts, etc. IMHO, this type of speaker is much easier to get perfect (for it's limited response due to the two way design) because the parts are all world class. Based on what I know it seems that everything is tweaked in this speaker also. It's sort of a tour de-force design.

How does the Merlin compare to the VMPS? Well, that's a question that is not easy to answer. Each of these speakers is awesome it what they do right: the VMPS sounding like some of the huge ultra expensive speakers in terms of dynamics and sonic integration and the Merlin getting you into the details of the recording with ultra precision that very few speakers in the world can achieve, at the expense of massive dynamics, ultra low bass and a sense of hugeness (vertically) that only monster towers achieve. Which one would I take? That depends on what my priorities are in terms of music, my room size and my wife! IMHO there is no correct answer here because each speaker achieves greatness at what it does right and each speaker doesn't have flaws that are readily apparent if you take each speakers' positives into account as you are auditioning them. For example: As long as you are not looking for the absolute best sonic detail ever imagined from the VMPS, you will not be disappointed. As long as you are not looking for the best low bass and huge dynamics from the Merlins, you will not be disappointed. Each speaker is wonderful and achieves greatness in certain areas that the other speaker lacks and visa versa. End of story, end of argument, silly argument at that. That's my opinion in a nutshell.....now, let's fight... ;)
Why all the defensive posts on VMPS? Here's some more details on VMPS' speakers, just so everyone realizes that they are damn good, but NOT the absolute gestalt of speaker designs which are not built to a price point.

As I stated in my prior post, Brian pulled off an incredible feat with his RM-40 design IMHO. He managed to offer a full range kick ass speaker for around $5k that has many qualities of $25k+ speakers made just a few years ago.

Now, "just for the record" here is where the VMPS speakers are not absolutely perfect (but again, damnnnnnnn good!):

Those circular ribbon tweeters ARE made in CHINA at under $40 a pop. They are really good for the money but are NOT perfect by any means! Slightly colored as compared to the best of the best ribbons or domes (at $235 to $1100 a pop!).

There is a response dip in the RM-40's above 15Khz due to cancellation effects that the two tweeters interaction causes. The new single tweeter upgrade ; (read non-circular) solves this issue very elegantly. Additionally, it is a much higher performance tweeter too! But as for the dual circulars, it is a cost driven compromise IMHO. That being said, it isn't easily recognizable as a compromise when you listen to the RM-40's on their own without comparing them to VERY expensive speakers done right.

The midranges are also a great ribbon driver for the money and probably one of the greatest design implementations that makes the RM-40's do what they do soooooo well. They crossover extremely low, so there is no nasty crossover point in the lower midrange to worry about. I applaud Brian for his ability to see the beauty of this driver's potential. That being said, I do have to inform everyone here that this ribbon is NOT the gestalt of all ribbon designs. All you have to do is look at the waterfall chart of this midrange ribbon to see that it is "relatively" clean, but not up to the absolute levels as some of the "cost no object" ribbon designs. I really like this driver, and could probably live with it for ever, but if I were building a cost no object ribbon speaker, I would "stack" the "best of the best" ribbons instead. This would achieve a superior waterfall plot and sound even cleaner than Brian's chosen ribbon (think Genesis or Infinity's speakers and you get the idea here).

Per my first post, I recognize that Brian makes his own woofers (that's what the term "tooling" meant). I think he really knows what he's doing here based on what I've seen of his designs and choice of materials.

In regards to the internal parts inside of VMPS speakers, Brian isn't cheap but I am ABSOLUTELY convinced that any owner can improve his RM-40's sound with better wiring than Brian uses. I think Brian did a great job based on his limited budget and at least uses decent wiring suited to each driver. I think most audiophiles would be shocked to discover how many big name speakers have such crappy internal wiring! That being said, this is one area which all VMPS owners can further improve their speakers themselves.

One poster here got pretty defensive about my statement; " As long as you are not looking for the absolute best sonic detail ever imagined from the VMPS, you will not be disappointed". Well let's face it, the VMPS are NOT the end all speaker in the world today. They are damn good and I love them for the money. I have heard better detail in the highs from under $5k speakers using better ribbon tweeters than the circular ones that Brian uses (GR Research comes to mind). I also have heard less coloration from speakers using Hyquphon domes. As said by others here, the FST upgrade solves this issue.

Hopefully I've clarified MY position and prior statements here. I do get very tired of seeing many posters (on this and other forums) put VMPS at the very TOP of the speaker design pedestal.

I've always felt that Brian is one of the most talented speaker designers in the business today. IMHO is one of the very few speaker guys who has found very ingenious cost saving ways to get close to the best sound of the speakers which very few normal people can afford. He is one of my heros. Way to go Brian!
