  1. I think that is a good point to end the discussion. Both points are true, but if asked the same question on a forum I would answer exactly the same way. Your point about remotes is very relevant and I can understand as you get benefit (lazyness ) from using it. I see no benefit to be had from balanced lines in hi-fi apart from just a personal choice - so be it.
  2. You still miss the point, this is not about the individual and his choice, that goes without saying, even as said before about owning a one box Bose. This is a factual technical matter, with argument to show that the use of balanced lines in hi-fi is purely a marketing effort, and explaining that. I used to build amps for large PA rigs and I would no more use single ended connections than drill a hole in my head, because that is their job, they are better at that, because of the circumstances of the job. The circumstances of the hi-fi job makes it pointless and irrelevant UNLESS it make the customer happier for some psychological reason.
  3. I think you miss the point, but I agree if he is happy then fine. The point of this thread I thought was not about him and his system it was about if balanced or unbalanced was best. I have explained the history, the reason it was invented and used, its hi-jack by the hi-fi industry. Learnt something on the way that someone is creating balanced gain circuits and has a patent. I don't know if that is better or not, but if a balun or a op-amp circuit has to inserted either end of the balanced line THEN FOR A CERTAINTY it cannot be better.
  4. But they aren't as far as I can see, it is all single ended with conversion circuits. To convert you have to use either a balun or a sum and diff circuit wrapped around an op-amp, more nonsense in the way of the signal for no reason but marketing.
  5. In this case not true as it comes from experience, if there was doubt I would say so, as with Mr Pass so I accept it is the case. If I am proved wrong I apologise, but on these subjects people have been trying for about 5 years - no coconut, but no apology of course. Variance - racks as hi-fi neccesity = wrong, racks as furniture you choose to have = right. The other two no excuse.
  6. Its on topic. Thanks for the compliment.
  7. I'll go first with the two in front of them Garrard 301 and AT 1005mk2 Bottom front Grey arm, looks original but as this is Japan could be a NEAT clone, my guess is a neat broadcast TT as well.
  8. Competition - name the TT and arms as seen.
  9. Well good for him, so he is not a band wagon jumper. So what is everyone elses excuse.
  10. Troll - good bait on the hook but wrong river.
  11. But the circuits they are connecting are single ended so how can there be an advantage - it is just marketing, a way to convince you, sell to you - "look I am clever and different".
  12. Yes But if your want them for some obscure reason who I am to stop you. I am just telling that thing known as reality.
  13. Obviously, some thing we do need and some things we don't. People make their own choice and if some choose Bose, in fact many more choose Bose because of convenience, good for them. BUT I thought this was a hi-fi forum, am I wrong? None of those things mentioned are about marketing, probably the nearest to be accused of that would be a BMU and it took me a while to decide to make or not, in the end I had to because of the benefit. Where as in the cases of racks, electronic crossovers and balanced lines I used them when I made pro-market gear so I for one (it seems other don't) understand why, and why they are a waste of time and money in hi-fi.
  14. IMO the problem and reason is marketing. The marketing are always looking for new angles and new stories. They have discovered a good source for these is the pro-market, it has specific problems that do not apply to us but stories and silly charts and equations can be made up for marketing purposes. The two main ones are balanced lines and electronic crossovers. It started in the late 70's early 80's with The Flat Earth which was a way of turning hi-fi into home PA systems, in yer face, agressive, but lots saw it as exciting, as big stadium rock was all the thing with massive PA's. Other things that came from it were racks, again marketing and expectation, to the extent that in the 80's cheap music systems were made to pretend to look like racks. Racks have now just becme a thing we expect to have, the marketeer hope to make balanced the same. At times people need to think out of the box, do we really need a lot of these things to get our music the way we want it - per usual marketing add ons just usually get in the way.

    Both spider and surround have to be considered as they are terminations. Music is a wave that propogates until terminated. Terminations are important due to reflections from them.

    An alternative way to observe. Music - Note that when you throw a pebble in a pool of water or into a quiet pond, the wave goes out in all directions. Yet a leaf floating on the surface of the water does not change location because of the wave passing underneath. In other words, a wave can pass from one point to another point, in the water medium, yet all the water molecules remain in their original location. That is characteristic of wave phenomena. A speaker cone behave the same way, it is not pistonic it is a wave. Many, many have listened their whole life yet still do not understand listening energy. Music requires “listening” energy, and transformation into emotional stimuli. Even just a discussion of “listening” will puzzle many people. Some believe that listening only practices the sense of hearing. They insist on deleting the word “listening”. “Listening is the most appropriate word.” Just consider how we are able to hear a sound from the other side of a wall. So remember the word “listening” is the key to understanding energy. Energy is a wave. Music is a collection of waves that move you, they stimulate you. Music in electrical or acoustic form is still the same wave, the medium has changed.

    A cone propogates from the centre out, the higher the frequency the nearer the centre, hence parasitic cones. The deepest bass is released at the surround. So there are multiple frequencies going across the cone and released at different points * so they cannot be pistonic that would only happen at one frequency. Spider and surround should be considered part of this process and are not often considered. A roll surround on an acoustic suspension is pistonic at low frequencies as the cone sits on the air enclose so becomes part of the mechanical load. A speaker with a crimp surround loaded by an open cabinet or baffle is designed to flex at the release point, it whips the sound out. Pistonic action is a theory fantasy in all cases. * It is understanding this and how a cone propogates music is how I have learnt to dope cones so a crossover can be avoided, I do it mechanically because I know my drivers from experience working with them.

    This shows a total lack of understanding of how music propogates across a cone.

    "I think Shadders is saying 4 drivers with an area of 100 square cms would be equivalent to one driver with an area of 400 square cms." Doesn't work that way.

    So they prefer to fight the room than the baffle

    Ron - If they didn't flex you wouldn't have any music. Every speaker distorts it is a choice of compromise. My point is that the compromise has stopped being about music and has become about WAF and profit.

    That ain't reality, it is a good subject for discussion that is all. The problem is the trolls that appear, you can see who they are by your uppers.

    That is seriously off topic and childish, but it helps in showing the mentaility of the uppers.

    There is a way to do it, couple them in a isobaric config. But for a 12 inch equiv it would be two 8 inchers.
