Default Invitation to audition John K's OB NaO Speakers in Sydney 9/11/2008

Hi,

You are invited to audition John K's open baffle NaO speakers in the next club meeting of the Sydney Audio Club on Sunday the 9th November 2008.

I am asked to demonstrate my DIY HiFi system in the club meeting, including my implementation of the NaO speakers. Note that the NaO is similar to the Linkwitz Orion in its design approach. I have not heard the Orion but my guess is that the NaO should sound similar to the Orion. As we know, both Linkwitz and John K are the leaders in the field of OB speakers.

Yes I am biased, because I built my system, but I'd say in my opinion it compares very well to any HiFi systems I have ever listened to at any price point (and I heard a lot) in terms of overall accuracy, life-like sound presentation and musicality. Last week, I had a special guest, Mr. Gary Stavrou, the conductor of the Balmain Sinfonia, a Sydney based symphony orchestra, visited me at my home. When he heard my system, he said it was "quite good". He did actually help me to adjust my NaO crossover settings besides playing the piano with my kids and dinning with my family.

I would love to meet you forum members who live around Sydney.

The Sydney Audio Club organizes monthly club meetings. They demonstrate HiFi equipments borrowed from some leading HiFi dealers and club members. Monthly meetings are held on the second Sunday each month at the Epping Community Hall, Dence Park, Epping, NSW.

Meetings start a 1pm and end at 5pm. Music starts at 2pm sharp. There are two breaks between 3 sessions. People usually turn up 5-10 minutes before the music starts.

Non members can attend a meeting free of charge.

When I have a moment, I will post more information about my system. I am in a hurry and have to go now. Feel free to ask any questions.

Regards,
Bill

"Quite good"? I can stay at home and listen to quite good heh heh..only joshing.

Will check my calendar, but unfortunately I think it may conflict with another little hi fi shindig at North Richmond.

But then again, by the time I get there I'm nearly at yours, will try and see if I can fit in both.

out of curiosity, how does the venue affect things? Spose it can be a bit like a hifi show, can't really take away any real impressions one way or the other?

cheers bill

I'll be with Terry at North Richmond, not sure I would be able to make to 2 places in one day.
Epping could be considered "on the way home" for me, but not sure of timing, or even if I'll be ok to drive after our other meeting ........

Hi Bill,

LOL. Yes it is quite good, isn't it?

I had a couple of friends, both full time musos, come over one day, and they said "hey it sounds really realistic"

Gee. Well thanks for that validation. I already knew that.

Anyway, these guys are the kind that have a dozen guitars, listen to the notes, focus on the performance not the equipment, and spent countless hours in the studio.

A few years ago I had one of the guys over and he said
"You know there's too much at 800, maybe 850 hertz"
after listening about 2 minutes listening to my ScanSpeak
2-way. I was shocked. That's just far out amazing IMHO.
I can only surmise that all the time monitoring music behind the console has really tuned their ears.

Comments like "those cymbals are the most realistic I've ever heard through speakers, but you'll might find that some recordings will sound a little hot"

Musicians often struggle for the flowery verbiage that audiophiles seem to be so good at.

We audiophiles talk about air, image, depth, etc, sometimes coming from our imaginations. While Gary, the conductor, when I asked if the tweeter resistor should be increased or decreased, the trimpot controlling the woofer roll-off Q should be turned up or down, he would say something like this: "I can't hear the vibro of the strings!", "The violin sounds right but at the lower notes it sounds like a cello". I was glad to hear when I asked if the piano sounded right and had the answer yes. How many systems can reproduce piano sound accurately? the NaO does it reasonably well.

Who should we trust? the audiophiles ears, or a conductor's ears? No wonder the Orion speakers can be described as the "best" by some and "not listenable" by others.

Terri and Andy G,

You guys should made it to Epping and tell me if the other gears sound better or not. What have made you to decide to drive all way from Bathurst and Newcastle to North Richmond (up to 2 hours?)? those must be some fancy stuff. I do hope they better the NaO.

Enjoy your time in Richmond and if you do turn up in Epping just say hello and ask for me!

What about others?

I do realise that there are not that many DIY forum members from Sydney who post here regularly. How come most OZ members live in Melbourne? They must like the weather there, i.e. four seasons a day.

Brett is perhaps the only regular forum member who is (temporarily) living in Sydney, the place he hates.

Hi, Brett, I understand that you don't like OB, you don't like HiFi drivers (only your old JBL, high efficiency, PA stuff), you perhpas still don't like solid state amps, etc. But you may be surprised to find how the NaO sounds! come up not for NaO's sake, just for meeting some fellow audio nuts for a chat! Thanks for the offer of the LED mod. I have taken the 12B4A preamp to Joe Rasmussen (Allen Wright's agent in Sydney) and had Allen's supereg added to it. Ironically, after that, I have never listened to the thing as I decided not to use a preamp but a passive volume pot. So, the 12B4A preamp, although sounds very good comparing to the best preamps one can find, will not be in the show.

Hi Bill,

Sorry I can't make it.

I guess some of this depends on what violin and which piano you are listening to. I am quite please with the reproduction of both, in general. Considering my father was a violinist and my mother a pianist my exposure to such instruments was very long term and intimate. Mozart and Chopin are always among my reference recording, as are the Cream, ZZ Top,... Bob James, Earl Klugh, ....

I donít know that the lower range of the violin sounds like a cello, but I would admit that I tend prefer a slight warmer lower midrange giving a little more body and weight rather than leaning to a thinner, more strident sound. Of course, the lower midrange balance can be altered by the adjustments on the active woofer/panel crossover. Additionally, distance from the wall behind the speaker will affect the lower midrange response as well, as it will with any dipole.
