PMC versus Wilson Audio


Looking to upgrade to either PMC MB2  SE's or Wilson Audio Sasha 2's or Alexia 2's. I listen to mostly Jazz, Easy listening, Blues. Not much Classical in dedicated listening room. Room has been heavily treated with absorption and reflection. Room is 12' x 16'. Source is digital, no turntable. High current monoblock amps. 

Any insight would be greatly appreciated and would appreciate keeping the discussion on PMC versus Wilson Audio only. Thanks!

I think both are very high resolution speakers. The PMC is smoother and more forgiving from its use of the Seas soft dome tweeter. I think the Seas tweeter puts a very nice almost "tube like" influence on the upper mids/highs. The Wilson speakers are more revealing, transparent and high resolution, but it can have a hard or sharp edge on the attack in the upper mids/highs. Wilson likes to use Scanspeak drivers (mids/tweeter) and they definitely have their own signature. Which amplifiers do you have? In my opinion, the Wilson really need a smooth high bias Class A amp (such as Krell Solo amps).
Which specific models?  There was an "evolution" series that did not run big into Class A.
Your Evolutions One's are still a fully Class A amplifier and I think they would be fine with Wilsons.

If you want to try to pull out every little single detail and realism of the sound and music, then I think the Wilsons are better.  I think the PMC -might- be a little more engaging, but not quite as "real" sounding as the Wilson.  It becomes difficult here as it can be subjective and dependent on personal preference.  Anyway, those are my thoughts.
Wilson will mostly use a Scanspeak tweeter but they will rebuild the back part of the tweeter enclosure.  They have used other tweeters at times, but mostly Scanspeak.
Unless there’s an obvious sonic advantage with the PMC MB2’s I’d definitely go for the Wilson Sasha’s in white or silver.

They’re almost works of art. On second thoughts not almost, they are works of art.
Coincidentally I auditioned the Alexia 2s and the new PMC Fenestria back to back yesterday and today. Alexia 2s at a dealer, driven by Naim Statement monos, and Fenestria at the Festival of Sound show in London, driven by AVM 1.2KW monos. There was absolutely no comparison, the Fenestria blew the Alexia 2s, and everything else at the show out of the water. It could be the room or setup, but the Alexia was in a somewhat treated dedicated listening room, while the PMCs were in an untreated hotel conference room.

Alexias sounded like really nice hi-fi speakers, sounded great on certain instruments and voice. I do think the setup wasn't done 100% properly.  The Fenestria, they were simply stunning, my jaw was open for the first 3 songs. It's just a whole wall of music with precise image that wasn't picky about sweet spot, uniform and yet layered presentation, incredibly detailed and balanced with refined yet impactful bass.

If you are looking to spend Wilson Alexia money, please do yourself a favor and audition the Fenestrias. 

I've heard the PMC MB2 SE's sound tremendously impressive at shows.A real combination of bowl-you-over dynamics, a big sound, with timbral realism.   Especially from outside the room, it often sounded like a live jazz band, and sometimes even something like a real orchestra, was pounding away from within the room.   Then again..those PMCs do seem to be demonstrated at "turned to 11" volume levels at shows, to show what they can do.
I wasn't nearly as impressed by the smaller, narrower floor standing models I've heard from PMC.  I found them competent, but unexceptional.  (Then again, I haven't had time with them in really optimal conditions).
@prof Your description os the MB2 SE is exactly my experience with the Fenestrias, it just felt like those speakers had no limits in all aspects of sound. The PMC rep there said that they were trying to bring the same level (or better) performance of the SE series to more home friendly speakers.

That was my first time hearing any PMCs and I came away so impressed thinking I must check out the rest of the PMC line like the Fact. It's kind of disappointing to hear that they are not all that special in comparison. I guess I will just wait for them to launch the lower level products under the Fenestria.
If your room is 12 by 16 you can not use any speaker with extremely deep bass.

That means much less lofty speakers.

A speaker with in room bass response to 35 -30hz and no lower.

Unless your room is open to another room you will get way too much bass and it will be boomy.

@prof and @divertiti are you saying the new Finestria's are a huge step up from their MB2Se's or just a better looking version of the ugly MB2's.

I don't know.  I've only heard the PMC MB2 SE, and that was at audio shows.
Dear @twochannelaudiophile: Both seems as very good performers and at this levels we have to analize very carefully each speaker characteristics.

I never heard the PCM but I heard the Alexia and some other of the WA speakers.

By characteristics I definitively stay with the Alexia2 because the PCM woofer croosover at very high level: 380hz and this means that those woofers that goes really down in the bass range has high excurtions in that low bass range and these excurtions develops very high IMD that affects not only the frequencies  to 380hz ( as a fact those woofers are handling at least to audible 450 hz. ) but all over the speaker frequency range because at each discrete woofer bass frequency are developed its harmonics that came with that kind of added distortions putting " dirty " to the overall frequency range including the high frequencies.

You have to imagine that the excurtions/movements of those woofers to develops 25hz that same woofer at the same time is developing critical frequencies at 100-150-200hz and in between, the IMD is to high and we can hear it.

In the other side and at least in that crossover woofer regards the Alexia 2 crossover at 200hz with a lot lower speaker IMD and this too we can hear it.
Wilson Audio has a very high quality design and excecution:

The subject here is not if we like more the PCM but wich one can be truer to the recording, which one affects the less the signal reproduction.

If you really want it the PCM sound signature my adive is to go for its monitor alog a pair of self powered subwoofers, these are the monitors:

@usherzaleg I have only heard the Fenestria, but judging from the conversation with the reps, they are close. I would imagine the Fenestria edges out the MB2, it's been in development for 5 years and has some pretty state of the art tech. I was just stunned by how much better it was from pretty much everything else I've heard recently, that includes the Focal Utopia, B&W 802 D3s and Wilson Alexia 2s.
I do not have much experience with PMC. I however do Love the Wilson Audio Alexia Series 2. They're an amazing speaker. I have installed a few pair.
I have 1 pair in stock store Demo in Porsche GT Silver immaculate pair. We are restructuring our store. These are priced to sell.

Also have Alexx, XLF yvette, Duette 2 and more.
I think krell is not good amplification choice for Wilson. It is not the same league.
If you are krell lover you can go for it, I’m not gonna change your mind . This is just my opinion, specifically if you are jazz listener. 

I had PMC PB1is and now have Wilson W/P 5.1.  I was mostly happy with the PMCs; just was time for a little change.

I found that these speakers are actually more similar than different.

The Wilsons have a little more acoustic space/depth, and the PMCs sounded a little more accurate top to bottom, with leaner bass. Great midrange on both.

Disclaimer - I'm using MIT Matrix cables on the Wilsons which seem like a great match. The PMCs were less cable dependent.

Thanks @keithtexas . From what I read in your post, you feel like it was more of a lateral move. Do you think the move is worth it with the difference in cost between the MB2's and Alexia 2 or even Sasha DAW?
It's a big jump pricewise .

@twochannelaudiophile - yes, I think it was generally a lateral move - but the PB1is were not top-of-the-line PMCs like the MB2s (they were more voiced for home than studio), and of course the W/P 5.1 is quite a few generations old. I have not heard the Alexia or the Sasha. I liked the PMC sound so much I seriously considered the MB level and their active speakers too as my next purchase. Just came across a great deal on some mint 5.1s and had always told myself I wanted a pair someday. But if accuracy and musician-at-the-microphone-in-the-room realism is your cup of tea, the PMC and ATC dome midranges can be shockingly good. Of course, some people "can't handle [so much of] the truth".  'Live' sound can be a little unsettling. And potentially fatiguing I suppose, although not in the "something's out of place" kind of way.  To each his own. System matching and sonic priorities differ.
