I feel a strong urge to make a pun about Marconi and Macaroni, but I'm just gonna log off until the urge subsides.

“If I could explain it to the average Joe they wouldn’t have given me the Nobel prize.” Guglielmo Marconi Born: 25 April 1874, Bologna, Italy Died: 20 July 1937, Rome, Italy Affiliation at the time of the award: Marconi Wireless Telegraph Co. Ltd., London, United Kingdom Prize motivation: "in recognition of their contributions to the development of wireless telegraphy." Prize share: 1/2 WorkIn the late 1880s a previously unknown type of radiation was discovered - radio waves. It was found to have the same nature as light, but with a greater wavelength. Various physicists and technicians investigated whether radio waves could be used to transmit signals. In 1895, Guglielmo Marconi used radio waves to transmit signals over a distance of several kilometers. He developed the technology in subsequent years to achieve greater range. The foundation for both wireless telegraphy and radio had been laid. |

After testing the Springs, Brass Cones, Other selected Cones (other materials) I ended back with the LTR Tuning Blocks on the BP LTR Platform, and this all sits on BP LTR Tuning Rails. I'm going to let things settle more before I use the Top Tune Canopy. When finished the CDP will have Top and Bottom transfers. This may sound new to some of you but if you want to visit TuneLand you can see pictures. Listening to some John Klemmer at the moment. Michael Green |
Mg. I have a selection of toys to play with along the lines you have described. I have Myrtle wooden blocks, brass cones, ceramic cones and lamp black glass balls/ footers. My 2 areas of attack in my mind were my integrated amp and/or cdp. Which have you found to yield greatest changes of those pair of pieces of equipment? |
As McMurphy admonished the other inmates in One Flew Over the Cuckoo’s Nest when he failed to lift the 300 pound water cooler - at least I tried. My only nit is that if you wish to be a member in good standing in the Isolation Club you should probably take a short course that describes how springs must be selected according to their springs rates and according to the load under which they are put. A very stiff spring would be great for a heavy component but poor for a lighter one, and vice versa. The math is not very difficult. I’d be happy to tutor you. |
geoffkait, I suggest you read a bit about Tesla's work, too. If for nothing else, but because Marconi was using a number of his patents for his work. Seventeen, if I remember correctly but I may be way off (many years have passed since I was in early grades of elementary school where I learned it). I am not trying to argue about it in any way, but the story, with all of its twists and turns, is not as simple as it seems and, check it for yourself, Tesla actually did get awarded patent for radio. There is a number of, often romanticized, stories about those events on the Internet so "cum grano salis" applies. |
MG. Amp is Ayre EX8 Cdp is C.E.C 3100 Rack is homemade. Consists of 4 x 24×18x2 maple shelves basically with all thread at all 4 corners so infinitely adjustable for height and level. But this means all shelves are not individual isolated. Which is why I wanted to try different footers etc under the main components. One day I will get round to building a better mousetrap! Really the legs I would like to come up with something better. |

Re Marconi vs Tesla. (Of course Tesla also was known for his work on DC power.) Marconi won the Nobel prize for wireless communication. Marconi was the first to achieve trans Atlantic radio communication. While it’s true Tesla applied for lots of patents for radio communication he was never able to achieve long distance radio communication. “There, he (Tesla) conducted experiments with a large coil operating in the megavolts range, producing artificial lightning (and thunder) consisting of millions of volts and discharges of up to 135 feet (41 m) in length,[146] and, at one point, inadvertently burned out the generator in El Paso, causing a power outage.[147] The observations he made of the electronic noise of lightning strikes, led him to (incorrectly) conclude[148][149] that he could use the entire globe of the Earth to conduct electrical energy. During his time at his laboratory, Tesla observed unusual signals from his receiver which he speculated to be communications from another planet. He mentioned them in a letter to a reporter in December 1899[150] and to the Red Cross Society in December 1900.[151][152]Reporters treated it as a sensational story and jumped to the conclusion Tesla was hearing signals from Mars.[151] He expanded on the signals he heard in a 9 February 1901 Collier’s Weekly article entitled "Talking With Planets", where he said it had not been immediately apparent to him that he was hearing "intelligently controlled signals" and that the signals could come have from Mars, Venus, or other planets.[152] It has been hypothesized that he may have intercepted Guglielmo Marconi’s European experiments in July 1899—Marconi may have transmitted the letter S (dot/dot/dot) in a naval demonstration, the same three impulses that Tesla hinted at hearing in Colorado[152]—or signals from another experimenter in wireless transmission.[1]” |
Hi uberwaltz With the 3100, I would take off the cover and remove the dampening strips. Remove the feet of course. The wire tie back by the transformer I would snip and spread apart those wires. Same for the wires all tied together in the front. Spread those wires apart from each. Since the top cover is gone let them stick above outside of the chassis. Next loosen the screws on the PC board just a little. On this unit you can remove the transformer from the chassis (up to you). If you did take the power button away from the front panel and move it behind or off to the side of the chassis you could get rid of the shielding. I would start with the Myrtle blocks under both of these units. Once things are loosened up (I would also recommend loosening your wall outlets) pop on some music and let the system open itself up for about a week and let me know what you're hearing. At that point I can guide you in one direction or the other. What I tell folks is open up the signal then tune it back in. The more it is opened the wider the range will be when you go to tune back in. If it sounds weird during that week or so don't worry that's just the system adopting more energy and adapting (settling). next the Ayre Michael Green |
The EX8 Just like the CDP but a couple more things. I would cut away the insulators on the wire (that's the extra wrap that was slid on before the soldering was done). See the ribbon wire is folded? Straighten out that crease, you don't want folds in any ribbon wire. This has great sounding PC Boards BTW. I'd like to see a closeup of the stand offs to see exactly how that is implemented. The transformer can go up on a tuning block. A question about your rack rods. Are they zinc or mild steel? And the screws on the PCB and transformer are they stainless steel or zinc? MG |

Getting back to the subject (briefly) have I mentioned my latest breakthrough? Oh, it’s big. Big big. Bigger than big. You see, as it turns out the %&@!# CD, that thin wimpy out of round wafer of plastic and sputtered metal flutters and vibrates and rings like crazy. There is no way the error correct routines and laser servo mechanism can keep up! This is one of the main problems audiophiles who listen to CDs face, it’s no wonder they have been frustrated with the generic, compressed and blurry sound of CDs generally. And who knew? Background scattered light and CD vibration have been holding audiophiles back for almost 40 years. All that is about to change. |
@geoffkait My turntable sits on a 40lb sand filled box (Baltic Birch Ply) The "box" sits on a the shelf I built which is attached to the wall. Bought some springs today and am going to place them between the box and the shelf. Am currently using sorbothane semi circles Hopefully I am going to notice a difference :) |
