Grounding boxes

I think the position there is that the users have no need to know and that it will only confuse them if they did. Not quite the same as saying they are too stupid but in the same ballpark.

In fairness you can rarely get a comprehensive suite of measurements from any manufacturer for any product but in the case of the grounding box a specific claim has been made regarding reduced noise levels so it isn't unreasonable to ask for verification of that.

AFAIK, NVA doesn't make any marketing claims regarding measurements.

The grounding box maker, on the other hand...

Not unreasonable to have access to even basic measurement information were one considering whether a manufacturer's transducers are a suitable match for ones amplification and room.

After all, Are we not so very often advised to use ones own ears and simply listen to the music as Firebottle appears to have done.

I bought my current speakers based entirely on the spec and measurements. But mostly I buy on gut instinct alone or just out of curiosity.

Really, Whilst reading through the Cubette thread on the NVA forum the following claim by the manufacturer stood out somewhat...


"Lowest in room audible distortion of ANY other speaker made"

Presumably this rather grandiose statement is backed up by in room  measurments !


Bump - read the customer reviews, you really have to try, most of you will come out with a profit, as your current speaker will be worth more second hands than these cost new. AND you take no risk. AND if no likey I will pay for the return. NVA speakers (along with just about everything else about us) are subject to insult and lack of understanding, because they are so different, different looking, different (proper) presentation of music in a real room. Not fighting the room - working with it. The only speaker ever to look like Cubes was the Allison 6, but apart from cubic box we have nothing in common. Don't be scared to try, we are succeeding in the ability of the speaker because they are so different, where as all other commercial companies have got stuck in a "way" to do things with minor difference.

NVA has always believed in starting low in the range and building up through trade in as you get more confident of the products and the company. There is a lot more the others do, but the same in character or lack of, just *more* weight, size, clarity, image, bass = more real.

I intend to make our speakers a market leader in quality / price. Get in early get the bargains.

No wadding, No crossover, Doped drivers so crossover redundant, just protection cap on tweeter. Lined acrylic cases. Acoustic suspension / infinite baffle. Near or on wall placement. Easy to tune to the room. Have NO preference in music types as they have no character, they just play the music given to them. Lowest in room audible distortion of ANY other speaker made, because it is so simple but balanced. It just gets out of the way of the music, what ever it is.

It is making a direct comparison with all other speakers though so it really should have something to back it up even if it is a subjective statement. Results of listening tests in which it was compared to every other speaker on the market and the panel found it to be subjectively least distorted, something like that.

Would be one hell of a logistical exercise though. How many other speakers are there on the market? Must be at least ten thousand.

My answer would be to order a pair on 30 day return and listen for yourself. Draw your own conclusions based on listening and not lack of published measurements.

Entirely the points that struck me when reading such a claim Macca, and my own point being that Savvy Paul seems quite happy to except such an extravagant and apparantly unsubstantiated claim without offering any metrics, yet is concerned by the similar claims made by the manufacturer of this 'magic box', equally unsubstantiated by metrics. Both worthless hyperbole AFAIAC.

Hi Vlad,

Thanks for your feedback. Very kind of you to take the time.

I can understand how the NVA quote, in isolation, could be interpreted as hyperbole, but I disagree with the substance of your analysis, for the detailed reasons that I posted earlier.

I respect your (and others) right to interpret these matters differently. That's (forum) life!

All the best,

SP

Okay.

'I guess that's another statement of fact from Jez then'


At the risk of revealing how ignorant I am, can I ask if there is really no possible benefit from linking all the components to a star earth so they all see the same reference impedance? (which is what I think it does).

OK. But how do you account for people's experiences? Surely, no-one is going to spend over £3000 on something just for the sake of it.

Richard's claim of lowest audible distortion is vague, and I would expect if challenged he'd just change it to 'lowest perceived audible distortion' which could be backed up with a few owner opinions, given that he's all about the subjective experience it's no leap of the imagination to guess that this it what he means. Had he said 'measured' then he'd obviously be taken to task over it, but he hasn't, so isn't, end of really.

I think the Focal claim is likewise vague enough to pass. Unless you've already heard the speakers in your set-up then they will indeed be correct.

Macca, star earthing can have benefits, no one denies that. In some circumstances with various mixes of kit it can simplify the task of grounding your equipment boxes and reduce unnecessary gnd loops. Conversely it can also introduce them. The issue with grounding boxes is the 'magic sauce' inside them and selling people the line that it is this, and not the well known and understood process of altering the grounding arrangement of the kit that does the business. (if indeed any business is done at all).
