Santa or Buddha?

Numerous posts have referred to Nelson as "Santa" due to his generosity at the event. After watching him throughout the day, I don't think that label fully captures his selflessness. His willingness to share knowledge, not just parts, is what I found most impressive.

Nelson spent the whole day with us answering questions and offering help and advice, always with a smile on his face! Someone this eager to help another human being attain audio enlightenment is much more than just "Santa". Thanks, buddha Nelson!

Hey Choky!
You designed a very nice preamp. Sounds great! The only thing that I would see as a positive change is some kind of 4 channel volume control.



agree ;
I think that I'll this days try what I can do with simple U or H resistor - pot net as attenuator ; maybe that solution - with all drawbacks - will be good enough (Papa's style ,whatever you all think about him after Santa terrorizing action :clown: ..... ) ......... so any of us plain DiyA cheapskates can use dreky stereo pot as differential stereo attenuator ..... certainly not solution for all cases regarding source impedance, but worth persuing ....

Your preamp survived a number of soldering irons and it wasn't even supplied with a shunt regulator. It ran from a very simple zener stack / mosfet pass transistor series regulator. Not how you designed it I'm told. It performed well in spite of these issues.

yup ; I wasn't able to finish , in fact - to receive finished pcbs for Shunty from vendor in time to send them along with main boards ; besides that - there was few (very ) limiting factors in BAF :Pumpkin: presentation :
first one is fact that each :Pumpkin: channel draws ~ 80mA all the time ; that combined with Vlad's reg (hat down to him,he manage to find xformer , both pots ,case and forgotten reg (from drawer ) , besides all biz obligations , BAF organizing etc and to compel few frogs in water - to repair poor one bstrd preamp 😉 ) which is just one and just series , isn't happiest combination .........

second one is in fact mostly my bad - I just couldn't find 9510s in time, so I threw (IR !!) 9520s in ........ I misplaced little bag with micas , so I must use aaaargh ceramic critters in feedback lag.......

etc......

I have (humble as always) opinion that little barking thing will sound triple better and relaxed,combined with one Shunty per channel (two for stereo, four for quadro ,8 for 8ereo etc....) ....... :clown: and few more adequate parts

but - main goal is fulfilled - AR2 have new preamp,and that was goal of entire BAF ....... as my pal mpmarino revealed :devilr:

joking aside - real main goal is fulfilled with my open source :Pumpkin: thingie , and consequence of main goal is that I'm pretty proud that I was (even just virtually) part of open source meeting ....... bunch of little and happy boyz , hangin' and enjoyin' together, just occasionally enclosed in those old looking bodies .

Papa .

really One and Only ; even without knowing him in flesh , taking chances that he maybe is rabbit abuser behind closed doors ( as any of us can be behind doors ) , I feel joy in sort of knowing him ......

he must be kind a special to be capable of so great nutttttttttzzzzzzzinesssssssss........ :clown:

:rofl:
:rofl:
 
I gotta get me some of his tweeters ... They do sound real fine andhave about 95 db response! ...

Could anybody comment on these?


Yes, I'll try. I was paying special attention to those, because I'm working on something similar.

First off, they were among my top four favorite speakers at the show. They were biamped, with DEQX (sp?) digital crossover (LR4 at 200Hz?), with a Eminence 15" on bottom and a fostex fx120 on top. Through the whole frequency range, they had a very pleasing sense of tactility, characteristic to open baffle, that no other closed back speaker had. Especially for bass, all but one other closed speaker sounded muffled by comparison. They did not seem lacking in bass.

My main reservation was when driven loudly (we did a lot of loud listening in that big room), on complex passages they lost coherency in the mids. Their soundstaging really became mashed up on orchestral and rock music, when loud. My guess was that the 4" mid/high driver just cant throw as large a soundstage as we were asking of it. A couple of minor reservations also: the sound was so 'open' that on acoustic material, some tinny-ness was apparent in the upper mids, which I think is a characteristic of fostex drivers. Also, I think having the wide range driver only about 30 inches off the floor is a problem, in terms of soundstage perspective.

My reservations are just small things I would change. The speakers were very nice - very realistic detail, and no big frequency response problems. Congratulations to their owner!
 
I want to thank everyone who put this on, and everyone who came. This event was so much fun, I had to tear myself away when my ride came at 7pm. I lay awake in bed later, still thinking over all I saw.

There were probably tens of thousand of hours of labor in all the different pieces, in total. It was a joy and gift to be able to hear so much incredible, home-made equipment in one place, and I am definitely going again next year. Don't do anything different!!

I'd like to give a shout out to the owner of the Metronome's (with Hemp FR8's) - they were incredible. They were my favorite speaker of the whole day, by a good margin, and I wasn't the only one. The total synthesis of the music they made was a wonder to behold. We played them loud, and they really held their own. They were definitely more then a sum of good characteritics (fr, dynamics, soundstage..) At one point, someone had their Rega Planar 25 playing Ricky Lee Jones, and it was incredible. IMO, the best setup the whole day in terms of overall naturalness, body and musicality. Then, someone switched in the LossLess CD player, and it was very interesting to hear the difference. Educational, to say the least.

Lousymusician, they were yours I believe. Congrats! What are those brass/wood things? (post 622)

I also want to give a nod to the BOFU BIB's - they were the only speakers to give me the chills. At less then $100 for the pair, they were great. Not just for kids.

Anyway, thanks again to everyone. It was so much fun, my girlfriend still hasn't stopped hearing about it...

AR2: Got any of Aleks' presentation on video? ... suitable for UTube? 😀

I just started going through the footage and editing. The camera that provided overhead picture is not accessible to me next few days. I left it with other stuff in my studio, and I am off work for few days. I am using material from other camera that my son was using to record event.

Not too much said yet about Vlad's outdoor speaker / amp setup ... It did sound very nice and was much appreciated around lunch on the park benches close by. (It also has the above mentioned tweeters, which I think may be key to the sound quality.)

That is not my set up. It belongs to a netefx or Mark Steven Lewis from Sacramento, who made his speakers with Alex's help. He had his whole PA set up that we conveniently borrowed for announcement and outdoor entertainment. Thank you Mark! They were unique in sense that ribbons are used for power levels normally associated with PA systems. RAALs didn't sweat at all on them. It sounded as PA system without typical distorsion in HF region if that is possible. Thanks to RAALs it was.
 
I have one request to make:

I would like to post all the good pictures made of the event on the Burning Amp site.
I would appreciate very much if you could mail me the disc with your images. Please email me for the address. I would appreciate it very much.

Everybody did some photography and would be nice to collect it all at one place for the future.

I also would like to pronounce my fellow photographer WBS - Vincent Spanier as official Burning Amp photographer! I am saved thanks to his existence at the event!

Thank you
AR2 - Vladimir

Thanks Vladimir, you are too kind. 🙂 I just got home so I'll burn a disk and mail it today. I didn't have time to do much more than resize. I'll send you the jpegs I posted to flickr as well as the original jpeg files from my camera.

Vincent
 
That looked like an amazing event. Congrats to all involved and especially to those who posted their comments and pictures.

What a guy that Nelson Pass is!

Gutted I couldn't see one of my audio heroes at work - Alex of RAAL. The man has understated genius.

Thank you Magura and I am looking forward to see you again next year. It was real pleasure to have you here. I hope you had enough tourists time today to enjoy SF.

For the thread readers info:

I was fortunate to have a time with Magura in shop where he showed me a "few tricks" It would take me a few years (or never) of reading and web searching to gain what he showed me last night. I think next year we must and will have workshop on metal working with Magura as separate event. Maybe Friday night in my shop before the Burning Amp 2008?

Hm ..... Burning Amp 2008... that already sounds good.
