The NS-1000 kill many assumed better modern speakers still. The 100dB coax you mention may be needing great crossover engineering to play well and we don't have a reference about the outcome.

I had the opportuníty to compare a pair of ATC SCM 50A, 3-way active studio monitors, of the latest incarnation to a pair of recapped NS1000M driven by a new Electrocompaniet class A amp: The difference was not that staggering.
The ATC:s are extremely tight and revealing, as expected from top-class, extemely expensive studio monitors. The Yamaha combo actually had better transient response. Both felt fine mixing on, the end result made the client pay :-). I´d change caps, no point messing with a near-perfect design.
18/1": madness, coax or not. They will never meet at 2K.

Here are some thoughts from some MD's who do DBT research in the medical field but are also interested in audio.....


Here's another link to a paper given by Robert Harley, editor of TAS periodical, at a recent AES convention. He's been reviewing audio equipment for many years and has some strong convictions about DBT and the role of measurements in reviews.

They do, they do. And very well. =)
And FWIW - it's a 1.4" exit horn, not 1".

But for nearfield monitoring, the Yamaha may be the better choice - especailly upgraded.

For the record, my intention would be to use them in the midfield, at about 5 feet.

Default NS-1000M crossover schematic

here you go- I found this somewhere on this site (possibly this thread).

I enhanced it a bit for readability.

Have somebody already tried this crossover for Yamaha NS 1000M ?

Thank you

I am still amazed at the original iron core inductors they are still far superior to the air cored ones of ANY value. I have spent a lot of money on inductors - goertz and mundorf provide exactly the same effect as wired inductors.The voices and instruments lose body and tonal detail and natural warmth become less obvious. There is simply a more lighter albeit airier presentation with air cores.When I listen to people in front of me talking or hear acoustic /classical music live,it is the presentation of iron cores that is closer to these acoustic sensations I register in my brain.

I will need to try some of the more modern iron/nickle core inductors.

With my experiments I have learnt that the the Yams love audionote cables inside and out by a significant degree. I still tweak the cross over , and after much experimenting the only other significant improvement came after I used audio note copper caps as bypass for the mid range cap. More detail and clarity to a very significant degree.Doing this to other caps did not bring out a real improvement.IMHO of course!!!!!

I have yet to reach the limit of the Yamaha's, as I am more and more amazed by the detailed and realistic presentation they give each time i purchase/upgrade a component further along the chain i.e amps and sources. Some of these components include JAdis JP S2, audionote m5 pre, audionote signature silver 300b mnoblocks, and my favourite by a mile my own very very highly modified JAdis Defy (also not apparently a limiting factor in the chain!)audionote dac 4.1,revox , pink triangle da capo etc etc. etc.

I have not missed my stacked Quads at all since the crossover and internal wiring mods and removing the wool from behind the woofer. Prior to that i could not live with its slightly lean and recessed midrange sound. So stock (although now becoming a slightly fading memory) it is not Perfect IMHO, far from it.

In case people have missed that part removing the wool from behind the woofer opens up layers of information and transparency which makes them sound even more live. But this then leads to an imbalance with leanness in the midrange and a more prominent sounding upper frequency range. This is where all the other mods readdress that balance and make transparency stay but bring back all the good virtues present before without the blanket over the sound.

I have just purchased OTL Atma -sphere M60's and am waiting their arrival from USA. Will they be too much of a good thing for the YAMS???

I have had close friends and strangers (collecting hifi stuff from my house they bought on ebay) gob smacked at the sound of the yams. Of course some of these people have known me for years and all my systems in their various incarnations so I must still be progressing.

Hi Audiojoy.

You may want to try an EI type inductor on the woofer circuit.
Internal wiring, I prefer solid core for all but with different

I have received the atma-spheres and yes they are special they have a transparency and ability to shape sound to make them more emotional involving than any other amp I have ever owned. There is a certain lack of upper bass warmth but otherwise superb. The strange thing i am now feeling is that I am once again beginning to approach and appreciate the sound of my hypersensitive avantgarde duo's I once owned.Speed and transparency to music making which can sometimes overwhelm you but in the end were not consistently satisfying enough to keep.....poor bass etc. Yes the Yams now remind me of my Avantgarde duo's but with excellent bass.!!!!!!!!when the atmasphere M60's are used.

Infact i would say that the bass on the YAMS are absolutely excellent with OTL's, wonderful speed timing and definition, which makes the notes clearly stand out from the mix instead of being a 'mishmash' of things.

Does any one know where i am leading with this in terms of forward progression before I figure it out for myself???

Salas you are usually in tune with my thoughts.
