Fussy with positioning. Fussy with system matching. Mediocre measurements. After all that still overly bright and fatiguing. This has been Bowers and Wilkins for a decade or more.

I always study the measurements first before reading any subjective reviews.

Hi

If I were to buy any audio, I would not read anything, specs & reviews irrespective. I always audition first with my own ears.

You may trust the measurement date & whoever critics' ears. Sorry, I trust my ear ONLY. period. Cause I pay with my hard-earned money.

Measurements can tell you important things, provided you understand how measurements match up with your personal taste and usage.

Measurements can also alert you to things that might become apparent later on but that you might not notice in a short audition, or when auditioning in a shop rather than your own home.

Learn to make measurements work for you. It will lead to better decisions in the end than listening alone. I bought my last two DACs (NAD M51; Topping D90SE) virtually on measurements alone, though I also read multiple reviews of the NAD. I loved it. When I saw that the Topping measured even better, I bought it. I love it too, and it's what I use now. I didn't have to listen or even read any reviews. Just saw the measurements.

The NAD M32 amplifier measurements looked good in some ways, but very strange in other ways. It sounded like crap. Those weird measurements should have raised questions in my mind, but unfortunately I trusted the reviewer. Again, measurements could have tipped me off ... if I'd paid attention.

Hi

Well, first off I never heard the sound of NAD M32 which tagged for $3,999. I do not know how good or bad it would sound.

Yet J.A. "highly recommended" it. Stereophine also recommended it as 2021 recommended D/A integrated amp.

You are comparing yr $899.99 Topping D90SE D/A with preamp out vs NAD D/A with built in integrated amp,

So apple vs orange ! It is a fair comparison ????

You blamed the crapy sound of NAD-M32 was due to its "very strange" measurement data.

You really think your ears were so powerful to hear the crappie sound of yr NAD M32 due to its "very strange" measurement data ??

So either there was a problem with the ears of yours or of J.A. who "highly recommended" it.

I did not make any such comparison. Maybe you need to learn to read English as well as learning to read measurements.

My god in these times I have
Never come across such anal retention and obsessive compulsive
Material,billion dollar babies!
More money than sense,if this is musical enjoyment well I guess I've been blissfully unaware of a community obsessed by materialism and price.... shocking and the marketing equally ridiculous.Never feel guilty taking money from mugs
Chasing the unattainable.
Shameful capitalism and the same old
Reviews with all your reference recordings.

Can you expound further?

If Paradigm can get back to their roots of making speakers that measure good, surely B&W can. The large diameter mids drive me batty, and the tweeter? If Vivid can do a tapered tube with a flat response, I don't see why B&W can't.

Hi

What does "making speakers that measure good" to do with the same sounding good to our ears ??

I've enjoyed my 805 D3s--siblings not too far removed--for several years. But both the strengths and the challenges described above ring true to me. Thanks

Very useful review, thank you.

“ … you need to audition”. No, I don’t. Nor any other model from this high-end pretender. I heard many models over the years and it is mid-fi at best. Still… spending a lot of advertisement money, will get you a “reasonably favourable review”. That I will give them.

Jack L's picture

Hi

Really ?????

So from yr having "heard many mdoels over the years", please enlight us on what brands/models YOU'd consider Hi-Fi.

Alas, I am still a PROUD owner & LOYAL lover of "mid-fi" loudspeakers. made in England. Too bad.

Hi Jack,
I also own an English speaker, the Kef 207/2. I have little desire to upgrade. Kef is what B&W would like to be but just doesn’t manage to become. If I were to upgrade I would like to get an Acapella speaker like the Atlas model. This seriously beats my kef. But Jack, I kind of regret my remark because it was never my intention to lessen someone’s choice of gear. Take care, enjoy our mutual hobby. I will too especially since we entered another lockdown here in the Netherlands as from today. Have a nice Christmas.
Cheers Wim

Hi

Sorry, I think we are not on the same page.

Now you've told us yr ideal loudspeakers are $117,500 Altas hybrid horn loudspeakers made in Germany vs $12,500 B&W cone loudspeakers made in England. 10 times price difference !!!!!

Like you were comparing a $121,000 Porsche 911 Carrea 4 with a Toyota Corolla !!! Major League ballgame with junior league !!!

For horn loudspeakrs ??? Thanks but no thanks for me, my friend.
I won't take any horn compressor driver speakers even for a penny !

Why? Compressor-driven horns get some distinct hornlike colouration. Any music will sound horny even a soprano! IMO. My skeptical ears get zero tolerance against tonal coloration.

Likewise, I prefer MM phono cartridges vs MC cartridges due to the distinct tonal colouration of MC cartridges.

Be my guest if you like horn loudspeakers. My skeptical ears just can't handle them.

Hi

Right on, my friend.

Thanks but no thanks to the new extremely contageous variant

My entire city has entered again in lockdown this morning: indoor asssemby not over 10 people. Outdoor not over 25 !

What a shame !

Are there any Audio Products that we don't need to audition ? ( I've liked every Magnapan design, so I'd guess that I probably wouldn't need to audition em if the price was right )

Paul at PS Audio is say'n their NEW loudspeakers are better than his IRS V5 that I think you once had some exposure to, I'm hoping you get to evaluate them and then recommend that we all go out to audition them.

You still own a pair of 801s after all these decades?, wow! Do you have the matching hoods that are kinda ugly ? I imported and sold those things, the 802s were farrrrrrrr more popular.

Hi Tony--

"You need to audition" is spot on--in two directions. You need to audition these because they are top tier speakers from one of the great names in hifi--your search would not be complete if you ignored them. But also--you need to audition because these speakers have characteristics that may be a problem for you--do not just accept them on reputation, caveat emptor.

mememe2's picture

A good stating point. A couple of questions though. First - which ear is it that you trust most , your left or right ear? Second. is your choice of ear predetermined by something as mundane as a hearing test- so that you know which ear to listen with?

Jonti's picture

I recently went for one. I have 1.7% hearing loss in my left ear and 0.9% loss in my right ear. This was something of a relief as it confirmed my instinctive bias to turn my head slightly to the left (thereby accentuating the quality of my reception) when listening in the sweet spot.

tonykaz's picture

We need to understand that a transducer system doesn't demand/require a blockBuster Powerhouse Amplifier fully capable of delivering considerable Current to loads down in the low impedance levels like the Thiel CS3s I used to sell. We had to demo those things with 200 horsepower Mono Amps that would double down in capability as they dropped below 4 ohms. Egads they sounded good with powerhouse Electrocompaniet Amplification but didn't do well with the Big Conrad-Johnson Premier Tube Amplifiers.

Measurements are critically important for people that can interpret the concept behind the design.

Mr.JA has consistently earned the "Audiophile of the Year" designation for these last 4 Decades. He might be a kind of Vanilla in the things he does and writes about but he's the best Vanilla we ever got.

Mr.HR, the Audiophiliac, Stereophile's Canadian writer and Mr.KM might be our up & Coming revealers of wonderful insights but we still need the technical matters properly described and contextually revealed.

Stereophile grew Into a great institution but without Mr.JA it probably would've just been another promotional Glossy
with glitzy snaps of Car Priced Record Players on the Covers.

I love to look at the last sentence of each measurement section JA1 writes and I read it as though Juan Antonio Samaranch is saying it. That sentence is JA's way of telling us what's really up.

Samaranch used to end each Olympics with a summary sentence that represented his view of how well the games went off. His schtick was...when giving the president's address at the close of each Summer Olympics, to praise the organisers at each Olympiad for putting on "the best ever" Games. But, he was fond of working in variations on that to give his true opinion, especially for 1996!

So, anyway, keep up the great work, JA1, will will continue to ruminate on each review's last sentence.

John Atkinson, please provide your opinion on B&W 804 D4 vs. 804 D3 speakers. Considering buying used B&W 804 D3 speakers. Thanks.

tyreman's picture

Methinks the pronounced treble or high frequencies still present, looks like fussy placement

reynolds853's picture

Opinions are like belly buttons, they say.

Specs and a reviewer's take are but two helpful inputs to consider. In this case, JA's perception was very close to mine (of the 804 d3 I own). I have disagreed with him on other reviews, but I have a ton of respect for him and his contributions.

I recently listened to the 804 d4 in a showroom and was less impressed in some ways vs the d3 but that should be expected because of the variables at play. The room setup at the store was not ideal.

I passed on several "flat" speakers and ended up with the "tailored" 804's. In my room, on my system, with my ears, at my listening levels and my recordings the 804's are simply amazing.

I look forward to the day we can look at specs and determine how something will sound (in our room?). In the mean time, I remain convinced there are qualities we simply have not figured out how to measure and enjoy the writings of guys like JA. I'm VERY glad all speakers don't sound the same. In the end, they are all pretty far from the real thing.

Happy Holidays, all.

Hi

Too true. But what better choice we music lovers will get instead of going to attend live concerts personally - time & money.

Considering the crazy pandemic going on worse & worse ! Public gathering is banned nearly everywhere.

Alternative is always something else from the real thing. Take it or leave it.

reynolds853's picture

I own the D3 and have listened to the D4 in two different rooms. Not a huge difference in terms of character. Tight bass that can fall on the lean side if pulled out into the room. The biggest difference is in the midrange that is less forward (closer to flat) than the D3. Top and bottom end sounded about the same. Not a great speaker for metal music or bright/thin recordings from the 80's, but great for all other genres. The D3 will work best when placed closer to the front wall. They will work best in a mid-sized room. Not sure if the D4 is the same with the relocation of the port. The D4 is the better speaker but you will pay 3x for it. For the ~$6k used ones are getting, the D3 is an AMAZING value. The better the amplification and the more power, the better. The "revealing" nature of this speaker will announce any shortcomings in your rig. They pair best with less forward gear like Mac or Musical Fidelity. Mark Levenson would NOT be a good match. They may be too bright if your room is highly reflective. This all assumes you are using them for 2-channel audio. Hope that helps.

Finally, scientific measurements by Audio Science Review (ASR). Yes, all speaker wire is the same. Humans can't tell the difference between coat hanger wires and $1000 cables. Stereophile has endorsed snake oil for decades now. But Roger Russel of McIntosh said that 30 years ago, the audio rags couldn't turn down the ad money. So glad Amir puts these old subjective (financially endorsed) ears to rest. High prices and advertisements no longer rule the hobby, the JUDGE has finally arrived, and as we know, most of these reviews are crap.

reynolds853's picture

ASR has interesting information, yet their conclusions are no more or less reliable than any other. I purchased one of the most respected (Okto Research) and most panned (BorderPatrol) DAC's on ASR forums. You would think there would be a huge difference. There is not and I can not say for sure that everyone would pick the Okto DAC over the Border Patrol. My point is, use YOUR ears. ASR, unfortunately is no more the Rosetta stone than Stereophile. I respect the work of both but there are many more trolls on ASR who are convinced they know everything there is to know. At least Stereophile has some humility about what is "best."

Bleib's picture

Well, you shouldn't expect a huge difference from among the components that are the easiest to get right, a DAC. Basically any of the top 20 measured DACs should be fully transparent, the fault likely instead lies in your loudspeakers / headphones which are far less accurate and clean.
Also, most recordings are not exactly great, so obviously even vinyl can sound terrific
