Romy and Paul,Many years ago, when I worked for Mille Nestorovik he used seperate mains and a sperate ground connection for the entire system. Before turning it on for a listening session, he would send me outside to "water" the ground, for a good ha...

Sounds to me like your switch mode transformer is doing the buzzing. I recently purchased an APC product that charged the battery constantly, so long as it was plugged in. This caused quite a bit of heat and stench, from the hot switch mode power sup...

There's no zero-crossing with A2 .833 or equivalent are a good choice for this extreme project and bass performance is excellent, I have heard 833 SE briefly and it has great authority.The driver would best be some sort of small/medium output valve d...

Thanks Bud!We often underestimate the fundamentally very physical way that sound is produced in our stereo circuits in complex electromechanical ways. I agree with Peter Belt that circuits are affected in ways that can be more adequately explai...

Bud, you may have read some of my babblings about stacking ground planes and stray current attaching/backing up all over the place; it's a personal fetish. Not to mention the fact that getting the ground "stacked" correctly is almost impos...
|

OK, Bud: This does appear, as I projected earlier, to be case in point for the "expert approach", using technology/techniques/machines that don't pencil for DIY, to say the least. I mean, you're not saying you lay this stuff up yours...

[quote user="Bud"]Sounds to me like your switch mode transformer is doing the buzzing... There is always a turn on buzz, but just for about 10 seconds. The original one had a noisy fan also, to keep it from self igniting, perhaps that is your actual ...

Romy,I have no direct knowledge about these products. I only have a brochure, given to me by an evil person... well maybe not evil, but he does try to get male children, who are friends of his male child, to play in "Garage Rock an Roll Bands" rather...

[quote user="noviygera"]What is that round yellow thing in the right corner of the picture? A driver of some sort? [/quote]Yes, they are Fane 24” bass driver with 24Hz primary resonance. I am waiting for the final sound check; the final is long time ...

Bud, excellent footnote, and just the sort of thing I always find out about the hard way! Still, the effing C hinge also "adjusts" according to R, while the shape of the curve changes as the L changes relative to the changing C...Sure, by all means ...

Thanks Romy.Sounds like tweeter on top will be best approach in my situation.The room is a good size and shape - 23ft x 15ft with 9ft ceiling . Plenty of room above.As you say the 288 on Azura does go to 12-13k OK with some beaming - almost enough re...

Hi all.I am just supplying a couple of threads that are dealing with application and the theory behind the EnABL process I provide information on here last year. Romy, you should not go there, it will make you crazy and you will have to insult someon...

Romy,We have discussed apottted Compression Driver's before, and I would not commit to promising performance you would like. Howere, here is a place where spotted speakers might well answer your needs, without altering anything you are currently doin...

Hi, BudNow that my system is back up and running again I suppose I ought to at least take the offer to try the enabl'd drivers in my speakers.I have no doubt they will sound different, and from the posts you cite I imagine some particular traits will...

Brian,Microphone diaphrams, headphone diaphrams ,dome tweeters, all have to have the pattern applied with a technical pen i.e. Kohinoor or Mars. These are becomming a little difficult to find in all towns. A 50% mixture of Poly S and water should be ...

SOS, please note that your PP 2000 does not isolate one component from another within the reconstituted 60 Hz circuit. It only isolates those components from the noisy and variable wall voltage. Since you think you must isolate your TT and phono stag...

In this cable thread there are some ideas about materials and construction of cables. My most recent attempt for good-sounding shielded phono cables are from Bud Purvine, using his specialty Litz wire construction, Vampire 800C connectors, and unblea...

Bud, you might be correct and “spotting” a cone might have a positive effect and I most likely will send you are driver for your torture after I found a reasonable contender. Still, what you propose and what I would like to experiment with live in di...
|

I have a really barbaric suggestion... of course. I can set you up with 8 lLinaeum, soft, live horn, dipole tweeters. Stacking 4 per side should see you at 103 dB sensitivity and 8 ohms of impedence. You can stack them without interference diffr...

LT Spice will also provide some of this operational modeling. I have not used Leap, but inputting variable states in LT Spice will provide you with all of the linear state information you could want. Naturally music has no linear states.....Putting a...

Romy,About 6 mo's ago I purchased a Teac X7R becuse the man who ran the head mfg facility in Japan is still making heads and has new pinch rollers for the machines too. This is the X7R,X10R and X100 and X2000 series. The R stands for auto reverse so ...

Since I occasionally listen To K &K rakk dac unit and like it quite a bit I was looking at their phono stage for a long time. This phono stage is a little scaled down (in PSU) version of ART Audio Vinyl One unit which is very well regarded. Kevin...

Yes. Their is a direct correlation between surge current and dielectric materials dielectric constant. The voltages in question are high enough to use a thick dielectric material and just as with the effective resistance of the capacitor, there is a ...

[quote user="Bud"] The next time you are at live music, listen specifically to this "dark side" of the live sounds. Then listen again to your system. I think it is the key to a whole new level of reality in out favorite illusion.[/quote] I was on Sat...

True enough, Romy, most marketing and "advances" in ULF are aimed squarely at the HT "Market" these days, and this is the source of some of the buzz we are referred to. However, there is also the "Pro" sound "Market", such as it is. This includes s...
|

Yes, I understand Bud that anything might be done but I do not want any DIY solution. To deal with all of the shielding, with grounds… I do not want to be involved into all of it. Also, the transformer shall sit at the RCA exit jacks of phono cable. ...
|

Well, it hard to tell if any effect is in place. I have a conceptual felling that the effect shell be auditable and I would like to say that it is but I am not convinced that I hear any substantial difference at this point. Bud believes that in order...

Romy,
Put them in a box and send them to me. Did you notice the replacement diaphrams available on eBay? Gone now, but they did not sell so will probably return.Bud...

Interesting point of view Romy. I have been exploring what I think is the same phenomena with the silly Ground Control devices. Certainly the changes brought about can only be happening on the "dark side" of the notes, since the devices are connected...
