Goodbye

I'm happy to contribute the post count. Bye Minh.

I thought I would leave the Naim engineers some food for thought before I make a new home for myself.

The Power-Line connector is supposed to be "decoupled and clamped by an ingenious die-cast component." I would like to point out the fundamental flaw with this ingenious design. The photo below shows the connector. The main housing remains stationary whilst the die-cast inner housing is supposedly decoupled. I will refer to the top edge as the superior border and the bottom edge as the inferior border. If you look at the photo carefully you will notice that the weight of the cable causes the die-cast inner housing to come in contact with the outer housing at the inferior border (there is a large gap at the superior border). The point of contact along the inferior border acts like a bridge and transmits vibration through the entire connector. Therefore this ingenious design does not decouple anything:



The same can be applied to the design of the Air-PLUG on the Hi-Line. Imagine all of the concentric rings forming a spine. The weight of the cable causes the spine to flex downwards. Now all of the individual concentric rings come into contact with each other along their inferior borders. From the photo below you should be able to see that there is a slight gap between each concentric ring along the superior border. If you study the inferior border you should notice that all of the vertebrae are fused together along their inferior borders. Vibration will transmit into the main housing along the inferior border. The patented Air-PLUG design has not decoupled anything:



The same design principle is used for Super Lumina.

Minh, but what does it sound like. Who cres about the mumbo jumbo, SQ is what matters. I've never tried one but most agree it has a positive effect

I didn't think the plug designs intended to provide full mechanical decoupling (which would be very difficult to achieve given there has to be a physical connection, robustness / safety concerns and pricing) but provide a lossy coupling which is what they appear to be doing ?

I just love that that last post was moderated.  I've also had posts moderated and I find the rules on posting links confusing and sometimes  applied oddly but to be fair Naim are remarkably tolerant on what they allow to be posted on this forum.  From the hundreds of Chord Hugo threads, to the thread that will not die that pops up every few weeks to question the implementation of Tidal, lack of memory in streamers and downright lack of business acumen within the company, as seen by us resident experts, they are all tolerated where many others would have long ago lost patience.  I'd suggest having a few beers, listen to some music and come back when you feel refreshed.

No dramas, cheerio.

Sonn we will have had more goodbyes than we had from Frank Sinatra!

Well i enjoy your posts Minh. There not just the bland i bought the next black box up the chain And it sounds great drivel. Its clear you put time and effort into finding what suites you. Not an easy task from my experience.

Gosh, Wanderer, I've started doing that about 6 months ago...  'sonn'  instead of  'soon'.

It's wierd, I put it down to the aging process, the brain not communicating with the keyboard properly.  but it's comforting to find someone else doing it too  

BTW, I like your comparison to Frank, very appropriate !

Ducks for President......

Dux for dux!

thanks for making me laugh!!

and oh, welcome back Minh ! you weren't away for that long?

enjoy some music!

I received a post on my wall that nearly brought a tear to my eye. I have come to understand that there are members on this forum that will miss my departure. I feel inclined to stay and continue contributing for those that give up their time to read my posts. I will probably do as Lindsay suggests and take a break for a while. I will not discuss modifications on this forum.

Welcome back Minh.  We missed you, twice.

You are not allowed a third time (three strikes and all that) so you are a Naim lifer now.

p.s. brilliant, brilliant cartoon choice Tony.  Thanks for making me laugh

Don't worry Minh, George must hold the record for "I go, I come back!"

i am pleased you have stopped flapping about and sound a lot calmer. Good for you!

may i humbly make a suggestion?

please arrange with your dealer to visit the Naim factory at some point. i would suggest 'soonish'...

this may turn out to be an eye, ear and mind opening experience for you.

whether you will be able to teach Naim engineers how to design cables that are, in your view, more mechanically sound is something that you can report back on once you have made the visit.

Can't wait...!

enjoy...
