i can't back this up with hard evidence because i forget where i read this and where i saw the graphs but B&W's supposedly are not very accurate.
That's exactly what AJ has said (with graphs of on- & off-axis from Stereophile magazine review).

Although TLS Guy (and a lot of people) also thought the B&W800s subjectively sounded pretty good, if my memory serves me right.

And it's also possible that I may not like "actual stage instrument sounds".:eek:
Is that possible?:D
You won't know when auditioning, since the mediocre acoustic design B&W cannot reproduce the "actual stage instrument sounds", but rather this coloration of them:




Coloration, which clearly some people are either unable to hear...or simply like.
The Bose cubes can't do it either, but millions(?) absolutely love 'em....subjectively :).
The power of marketing over the mind is strong ;)

price is also a factor, if someone pays thousands for something they arent going to think it sounds bad, cause then they feel bad. i personally think all speakers should not deviate more then 3dB or they aren't accurate. untrained listeners are suckers for bloated bass (especially at 100hz) and overly bright highs. bose has both of these problems.

If that;):D Or, it may be in the negative direction:p
That's what AJ was saying also.

If we tell the average person that ultra-expensive speakers may sound WORSE than a high quality pr of < $10K speakers, they would have a hard time believing us.:D

Just like when we tell them that Bose speakers suck, they also have a hard time believing us.:D

I will probably audition the RBH T-2P/R Reference Series & B&W 802D (on the same day) in about 2 weeks on my weekday off.:D

I wonder if there is something that Wadia does with their digital processors that somehow makes them different from other processors.... they upsample to 2.8224Mhz, and they don't use analog volume controls at all.....

Anyways when you put the analog output from this box straight to a power amp, it's like a curtain taken away between the speakers and you (the listener)

Wadia uses proprietary patented technology and as a result of this it is bl¤#% expensive....

I don't believe that this or something similar cannot be done via a computer or that pro manufacturers (Behringer, Benchmark or others) are unable to do something like this, perhaps it's the patents that stop them :confused:

Now I don't know of it's what Wadia does in their digital processors that's a big trick or big breakthrough.... or whatever.... Is there anyone that's done real A/B testing with Wadia products and others, like Benchmark DAC-1 or other well performing DAC's?

Anyone that can shed some light onto this?


And about B&W, mee toooooooooooooooooo
I have big issues with them, can't stand them.... the way they sound.... horribly artificial and non musical....

Give me Meadowlark, Dynaudio, Vienna Acoustics, Duntech, Audio Physic, Adyton, Audiovector, Proac, Von Schweikert, Dali or System Audio instead...... they are well sounding speakers
Also VAF, Vandersteen and Thiel..... but I never listened to them so I can't really say.....

I have to admit that I have not listened to a lot of speakers out there.

I'm far from being a speaker expert or a professional writer/critic.:D

When I audition speakers, the only 3 things I look for include:
1) clarity of the sound,
2) full sound spectrum, and
3) lack of listening fatigue.

Speaking of speaker fatigue, I can listen to my BP7000SC @ 85dB volume and still fall asleep. :D

I've listened to some speakers where after 10 minutes, I just want to put on some ear plugs because my ears "hurt".:eek:

In the end, we have to let our ears be the final judge, which is what most of us believe.

When it comes down to paying that big chunck of $$$, we are buying the best sounding speakers to our ears, not other people's ears or ideas.

This 2nd B&W dealer tells me that their show room for the 802D is decked out with room treatments and Classe components, so there will be no excuses this time.:D

The RBH flagship speakers reside in the store owner's home, so that should be nice.:D

Where are all the B&W 803/802/801/800 owners out there?:D

What are their sides of the story?:D

And I would like to know what TLS Guy has to say about it.:D

That...or maybe the gain is higher than the removed preamp. Who knows? :)
Is there anyone that's done real A/B testing with Wadia products and others
You would think that if their products were really (not imaginative) sonically superior to others, that the onus would fall on them and be to their benefit, to perform or have independently performed (maybe even free by a higher learning institution, etc.) a controlled, blind test that eliminated the imagination, gain, etc., etc., etc. from being the reason. Then they could legitimately claim and advertise based on real evidence, not anecdote, that their products were indeed superior...and therefore possibly worth the exorbitant prices.
But of course, they won't. Hmmm......:rolleyes:

Makes sense.

No need to stir the pot.
We know that side of the story, not just WRT to the 802 or Bose, etc.
"I heard it", "I said so". "Sounds great to me.....so ef the (reality snapshot) graphs"....excuse me "specs" :D

AcuDefTechGuy has sent me a PM insisting I give my thought. So I will give an opinion.

I don't know all the range by any means.

My view of the 600 series, though not terrible speakers by a long shot, could be better for the money, and to be perfectly honest I think B & W know how.

I have heard some of the CM series and there is very definite improvement.

The 800 series are the best of the bunch and the ones I know best are the 800 D and the 802.

These are expensive speakers and you should expect a lot.

I know the 800D best and as a good friend has them.

They are beautifully made and the cabinets highly non resonant.

On the whole they are well balanced. Voices are full natural and stable.

Since I don't want this post to go on fer ever, I will list what I think are the negatives.

The bass I find one of the problem areas, I understand the new 800 Diamond addresses that somewhat, but there is not one in the Twin Cities.

What I notice is port lick in. No chuff from the ports. But I just can't forget the bass is reproduced. These speakers are pretty large and yet they still need a sub. I know I'm fussy, as I have worked with TLs for a very long time. But on my rig here the bass strings, tymps, bass piano strings etc, do reproduce faithfully and sound like the true deal, and others agree.

In fairness I get this to some degree with almost all QB 4 boxes. However I'm very aware with the 800 Ds where the port takes over from the drivers.

The next issue is that I perceive a problem with the crossover from the mid range to the tweeter. There is a definite lobing issue and change of balance and perspective with listening position and height.

Depth of sound stage is good but I feel could be better.

I would like to hear more space around instruments. Its there alright, but I don't get that feeling of instruments really being totally in their natural space.

The problem is I am yet to hear a commercial speaker of the cone type, that I like better than the 800 Ds. Now there obviously are vast number of speakers I have never heard, so that by no means means there isn't one, I just have not heard it. These days it is very hard to hear the high end speakers. At least round here dealers do not stock them and will only order them after a deposit. So the dealer has to arrange for the audition in a customers home. So it is difficult to really evaluate things.

In short I prefer my speakers here by quite a wide margin and so does the owner of the 800 Ds.

The major advantages are a deep realistic bass. A more natural softer sound, especially on the strings.

A much better sense of space especially around solo instruments. This is combined with an improved sense of space. This is nowhere more evident than listening to cathedral music where the gentle stops often accompanying the choir can really be heard as floating round the cathedral, with the organ high above the voices. Its uncanny and in my experience rare, and in all honesty I could not tell you exactly why. So in all endeavors involving science, craftsmanship, art experience and judgment, there is still that element of luck.

So I guess to summarize, if the 800 Ds were my design, I would still consider them under development which I guess they are as B & W have just introduced a new model.

And my speakers have also been under development with a number of revisions. An extensive revision was done to one of the active crossover a few months ago. So that is the nature of the beast. Its an area were DIY is huge advantage. The builder, like the organ builder, is building for one space. Upgrades and changes can be made without the hassle of selling the speakers and putting up ante for new ones. I just feel very fortunate not to have to enter the jungle of speaker shopping especially at the high end.

two things I really look for when auditioning
- Do I enjoy the music
- Can I forget about techique and does it seem like genuine music.... with no electronics there.....

Well this is not about gain... or simple tricks... just music is so much more realistic.... heaps more realistic... but to believe that we will get the same by bying the same equipment is just fooling ourselves... wish there was an easier way to go step y step to get a superduper system at an affordable price

Ok. Then give us all the details of the test. Level match measurements, test conditions, material, etc. Was it single or double blind, the statistical results, etc.
Thanks.

This falls into the anecdotal, "I heard it, I said so" category, without test details.

There is. Just put the Wadia et al faceplate and price tag on a inexpensive but competently designed equipment and observe the fMRI's, like this.

No trick, just simply being human, despite Audiophile self-denialism. ;)

Please bring along with you a few SACD violin concerto, piano concerto and something that has a lot bass drums. I hope you do like classical music. To me that's where the 802D stands out from the P362. If you listen to Diana Krall stuff the P362 probably does just as good as your beloved DefTecs right?

I'll bring some classical music this time.

With the exception of the Operas, I believe I have most of Mozart's works - Symphonies, Violin & Piano Concertos & Sonatas. I have Beethoven's Nine Symphonies, and most of Bach's Organ works.


If you listen to Diana Krall stuff the P362 probably does just as good as your beloved DefTecs right?
Not really.

The bipolars just sound different than the direct radiating speakers.

But I think this is with all bipole & dipole speakers vs. direct radiating speakers.

The bipolars just sound "fuller", and I don't just mean more BASS; I don't how to describe it. It sounds like I'm in a "symphony concert hall' - like the sound is not just in front of me. Even at low volume and little bass, the sound seems "fuller" from the bipolars (BP7000SC) vs. direct radiating speakers (P362).

I think once you've listened to some propertly setup (properly placed) bipole/dipole speakers, you will see.

....You know....kind of like that Audio Critic guru and Linkwitz guy.:D:D

How I know that it's not about gain?
Because I used a SPL meter calibrated by swiss official governent authorities to verify listening level

We cannot verify by measurements becase we don't know enough, measurements is just an approximation that we made to make simplified models of the physical reality and there are so much we humans don'tknow..... how can we even start to think about measuring everything..... we don't even know how gravity works, how can we then say that we are able to measure

Best measurement tool is our ears.....

Music is not about measurements but listening to music, what gives you most pleasure

Looks like you don't even bother to read my post.... I'm asking if anyone have experience in A/B testing of Wadia's against other equipment

So if you are so sure about this, why don't you be more concrete and provide details about your experiences....

Wow. Really?
That's impressive. Here, I'm not sure I'd want to use a Govt one, but I digress ;).
This "Swiss Govt Authority" meter was accurate within human perception threshold 0.1db I assume?
Why not just measure and match the voltage output of the pre vs Wadia to negate the possibility of residual room noise skewing the SPL by >0.1db??

Ahh, ok, so you used an SPL meter.

Best measurement tool is our ears.....

Ummm, wait a second...then why bother with the Swiss meter???:confused:
Why not use your "best" tool Ears instead? You used an inferior measuring tool (Swiss meter) when you had a superior (Ears) one there??
Why not just match by ear/listening to <0.1db???

We cannot verify by measurements becase we don't know enough
We don't??

measurements is just an approximation that we made to make simplified models of the physical reality and there are so much we humans don'tknow..... how can we even start to think about measuring everything..... we don't even know how gravity works, how can we then say that we are able to measure
Music is not about measurements but listening to music, what gives you most pleasure
Really? You don't realize it, but the Wadia is an electronic device. It's output is electrical. If "we" don't know what to measure,can you explain the design/engineering method used to create the Wadia? How did they know what to do to the circuit to create this "real music" sound? Did they rub a frog on the circuit and know that it's electrical output would sound more real, or did they make physical and measurable electrical changes? Why don't you walk us through the steps of design/engineering an electrical circuit without measuring or measurable change. TIA.

Looks like you don't even bother to read my post.... I'm asking if anyone have experience in A/B testing of Wadia's against other equipment
I did read your post
Anyways when you put the analog output from this box straight to a power amp, it's like a curtain taken away between the speakers and you (the listener)
You did a comparison. You had a Swiss meter. What were the results of A/B (/X?) testing? Where is the statistical data? What controls were use? etc, etc.?
Strange how when details are asked (like where in Canada has PSB vs Infinity), these online tales start to unravel.
;)
So if you are so sure about this, why don't you be more concrete and provide details about your experiences....
What experience? About sighted, uncontrolled, pricetag hanging off the thick shiny faceplate bias overloaded "listening"?
Or experience with understanding human psychology and what affects the mind, like the Price link I gave you?
