AVI DM10 actives sat on Foundation 24” stands, typically fed lossless flies via an Airport Express. I splurged a bit on the Optical cable, it’s is a QED QE7100, 1m. RCA cable linking the two speakers is the standard one supplied with the speakers. As are the mains cables, which are plugged into just the room’s regular wall sockets.

Prrobably i’m only worthy to sit here and watch.

I have other stuff but this is my absolute reference.

I will have to mark this system down for the use of unbranded speaker cables but it gets a massive up tick for the expensive speaker stands, though overall I think the resolution is probably quite modest.

Still the resolution should be good enough that you will, by careful listening, be able to tell if anything is playing or not.

Excellent sense of humour :)

I fear in your drive for excellence in advice you have omitted the single most important factor.

The ears of the person doing the listening and advising.

Advice should also be rated based on an approved hearing test validating the ability of the advice provider to actually hear the full range of frequencies being commented on. This should, of course, then result in a rating system to be included in the signature of advice givers, and only those with aproven level of hearing should be able to offer advice to buyers considering gear above a set price point.

Sorry, could you say that again please.

In my defence, Pedro, I am more concerned that insufficient attention is paid to the fact that almost all this HiFi gear is designed and manufactured in the northern hemisphere meaning that it is upside down when used down here in NZ.

I have tried both standing on my head whilst listening and turning my R700 speakers upside down in an attempt to remove this problem from my listenening room. I am now experimenting with also turning my amp, oppo105 and nas upside down in an attempt to improve the resolution of both the analogue and digital parts of the system.

I fear you northern hemispherers don't fully take into account the difficulties involved in the pursuit of the perfect southern hemisphere system.

But at all points on the earths surface, gravity acts radially to the surface, so there is no 'upside down', see Einsteins theory of spacial relativity for more details.

There is an issue though and this is normaly referered to as the coriolis component. In simple terms it means that the most northerly part of your hi-fi cable will have a measurably greater angular velocity than the most southerly point and this will affect the electron flow.

Sceptical, of course, but remember this effect is sufficiant to cause water to exit through a drain hole in a spiral/circular direction that is the opposite of that in the northern hemisphere and a sink may only be a foot or so across and water is much heavier and harder to divert than electrons.

The only practical solution is to deconstruct your cables and rebuild them with the individual cable strands twisted in the opposite direction to nulify the effect of coriolis.

Needs to be done using the Golden Ratio of 1.6180339887498948482.

is only really of use on the macro level where, for instance, it can be used to calculate the correct room position for your loudspeakers.

When considering electron flow we need to consider things on a quantum level, altogether different rules apply.

We know, for example, that quantifying the differences in audio cables only occur when the performance of the cables is being monitored by an observer, regular measurement does not show a difference.

In quantum mechanics it is only the presence of the human observer that collapses the quantum wavefunction to give a defined result. With out the 'conciousness' of the observer the collapse of the wavefunction does not happen so their is no result to evaluate.

The observer is thus inextricably linked to the experiment, his/her presence actually has an effect on the results.

For more information, google 'the observer in quantum mechanics'.

I’m finding this a bit boring and asinine. If I wanted comedy I’d watch jimmy Carr, jack Dee...take your pick.

Imagine a closed off room with let's say £15k worth of hifi playing music (that includes cables) and a cat.

Until you open the door the cables both make no difference at all and a "night and day" one.

Good stuff. I'd wrongly put it all down to Quantum Tunnelling.

I occasionally leave music playing when I go out, with Lucyliu (in the pic, she is quite real) curled up very close to the sweetspot. Next time I do that I shall switch cables and ask her what she thinks.

Thank goodness someone remembered the cat. Ours cost £40 and there was £40 quid wasted on his brother who lasted less than a year. In the RRP analysis does this count as £40 or £80; we got no discount?

I got it I just didn’t think it that smart or funny, but that’s just me. Humour is real humour.

Watched this thread develop before I went to work today... Can't believe so many people fell for it *ROFL*

I've always known DDC to be very serious when discussing hi-fi but he also has a wicked sense of humour *biggrin*

Ah, so you don't have a £20K system then Quest, you only have a system worth £15 point 695.

I guess we need to reassess where the ultimate resolution margin is as it significantly lower than previously reported.

Quest, you're an okay kinda guy, I've met far worse than you in my life. But you are just not streetwise, you give us such a large target to aim at it's difficult not to take a quick shot just for the hell of it. Please chill out mate, we can't all be clones of you. Or find another forum where courtesy and manners are in accordance with your demanding standards.

One of the few I've followed from start to finish. Obvious (to me) from #1. The earliest AF1 I've come across - also liked seeing the minutae of some people's systems.

Great acceptance of the humour involved by most - Nice one DDC!

(to much BS on some threads - but not from you BS25!)

What you have to realise is that if you are speaking your post #97 to my face it doesn’t bode well. It’s not how people speak to eachother. And if you take a shot at people ‘for the hell of it’ as you put it, maybe you need to reckon as to whether this is ok socially and if you are right online, whether your moral compass is right. There is a person behind your comment, whether I’m to be streetwise to the abuse that goes online. I won’t stand for it. And you’ve no idea if I’m an ok kind a guy, as you put it, as you don’t know me.

These are not demanding standards. People like you will go before me. My defence is in exactly the nastiness you espouse.
