Ha, ha, sure, it gives me goosebumps with or without hood just by looking at it! My furniture is anechoic and because of my fabulously furry body, I'm a nude listener. You are also right in not taking audio too seriously, unlike other forums. But I'm still interested to know whether these sound waves hit the pickup having an impact on the sound quality or not and I was hoping to get some experts' opinion. I can hardly believe this topic never popped up in the B&O community.

As noted, to the audio file crowd the vote is overwhelmingly lid off. On my 4000, I mostly play lid up because I like it and sometimes lid down if there’s a lot going on (situated in living/dining). Cooking can also introduce unwanted oil and our air purifier in the living room shows orange/red when frying (well, when my wife fries on full burners lol). The joys of open plan. Two lil dogs as well but they don’t shed much.


I personally don’t hear any sonic difference up or down tbh.

Maybe you came across this already as it features quite highly up on the Google search. This is what Pro-Ject have to say if graphs is your thing:

I know * audiophile :)

LOL   I think that the stereotypical B&O owner has different priorities that the stereotypical audiophile. For example, I can't recall ever seeing a Powerlink cable that featured high purity copper, varying gauge strands within each conductor, opposing conductors pairs having left and right hand twists, Teflon insulation, 24K gold plated connectors, all double cryogenically treated. I'm sure that many of B&O's customers have the means to buy such a cable, just not the desire.

Yes, I came across it, also actually posted it already :-)

Like Glitch, I'm missing the loudness level as this seems crucial to me. Anyway, I'm not wondering about the lid up / lid closed difference (if down is bad, up is even worse, following the same logic), but about lid closed or off. According to Pro-ject it's off = good, on = bad and up = worse.

We can also leave the whole cable alchemy discussion to the "audio files" (like that neologism) although there might be a difference between signal transportation for active and passive speakers, I just dig fat nicely braided cables for optical reasons. IMHO, the stereotypical B&o customer nowadays, I'm afraid, is primarily wealthy, his audio gear just part of the furniture selected by the interior designer. Guys spending their time in forums like this one are no longer the target audience but mostly old gear owners, a rare breed in extinction. B&o never was cheap stuff, rightly so, rather middle/upper class, but today they don't match neither much my taste, nor my budget. They should have kept a high quality analog, down-to-earth line in their portfolio including a record deck < € 10 k! ;-)

The slant design theory is also interesting, I always thought it was just due to the Zeitgeist... Login to view image

Yes, so you did post that link, sorry I missed it!

I also thought that the slanted lid was simply part of the design. Whether it had beneficial effects on resonance was likely coincidental.

beautiful shot of your BM8000 and BG8000. Unapologetically 80s.

As for cable, I’ve tried many over the years and there’s definitely a difference to be heard. I installed 12m of Furutech cable and hated the sound. Then I switched to QED 75(?) and was much happier. That’s all gone now, now powerlink cable and Steve’s cables and very happy.

Thanks! I actually made an early transition to fully digital in the 80's and already back to partially analog in the early 90's because of the horrificly remastered" early CD's. Luckily never got rid of my LP's, so I still had a comparison.  Now fully analog, at least regarding my serious listening habits. Switched my BL9 against MC102.2 (.2 because of the binding posts ;-))

Hard to try the BG8002 without lid, will test the BG4002.

The one thing that does make a difference on the cartridges is room temperature - tests on the MMC20CL showed that you really want the room temperature to be about 20 degrees - I imagine this is due to the suspension of the cartridge - and it does make a difference! The problem now is that most cartridges will have old rubber suspension and the sound will deteriorate. Luckily, getting old, the higher frequencies have mainly gone anyway and new rubber blocks not available for ossicle suspension!

I know, a nice old-school spot can help to keep the right temperature too :-) But again, I'd like to hear opinions/findings/speculation/test results about these alleged disturbing resonances transmitted via the lid. Maybe there's some ex B&O employee in the forum who remembers having had such discussions, back when he was very, very young? Maybe hinged lids are less affected or not affected at all, maybe it's just some more audio-file BS and a good, heavy lid shields against these waves? I have no clue. Anyway, I think the question is justified. One of these days I'll make a hearing test and post my very subjective findings. As said, digital is superior on paper too, but not so for my ears.

My slanted lid comment was made in jest. I've always imagined that there was a rivalry (friendly or not) at B&O between the designers and the engineers. It seems like a significant amount of the engineering innovation was a result of overcoming the compromises dictated by the styling. This seems most evident in the speakers made between the 1980's and 2010's.

Have you considered duplicating the pro-jectusa test? This seems like an easy test to setup. You would also have the benefits of testing at the listening levels that you normally use along with your exact equipment location and room acoustics. I don't put much merit in other people's listening tests". There are too many possible variables that make any results meaningless. Glitch
