| Vibration Control for Lightweight Tube Components Lowrider,according to the blurb for the IsoNodes they are vibration control devices as opposed to real (mass on spring) isolation devices. They are not springs nor do they act like springs, in other words. They are apparently some sort of viscoela... | |
| Has anyone heard the new North American products preamp and amp? Roger, by your own definition at least some of the distortions I am referring to - the ones separate from amplifier distortions - are DYNAMIC. Seismic vibration or any vibration, e.g., transformer vibration, motor vibration, that produces jitter i... | |
| Vibration Control for Lightweight Tube Components "The cheapest way to get great isolation: two Baltic Birch plywood shelves with a barely inflated bicycle tire between them, with a trio of roller bearings between the pre-amp and the top BB shelf (this design courtesy of Barry Diament). If you ha... | |

Assuming that their 1.75 inch height can be accommodated. I say this even though the de... | |
| Vibration Control for Lightweight Tube Components @geoffkait , what do you mean by mass on spring?Any any isolation device that employs airsprings, mechanical springs, tennis balls, bungee cords, etc. operates as a low pass mechanical filter for vibrations, where the component represents the mass... | |

I never said anything about the sweet spot nor about the final solution. You cannot win an argument by changing the topic."But it is what you two have been... | |
| Vibration Control for Lightweight Tube Components I have one word for you, mass on spring. Almost all effective vibration isolation solutions employ this simple technique. | |
| Most Effective Tweaks? Big fan of mu metal around transformers. I’m also a big fan of double wrapping and implementing spacers between layers. One layer absorbs 75% of the mag field, two layers absorb 96%. I also like wrapping those flimsy little exposed ribbon connecto... | |
| Has anyone heard the new North American products preamp and amp? Tbg wrote,"geoffkait, just listen to the amp.Yes, having all frequencies arrive at your ears at the same time affects the sweet spot. I abandoned electrical engineering when I discovered all they cared about was having a circuit that worked. I hav... | |
| Has anyone heard the new North American products preamp and amp? There are many room anomalies that influence the size and location of the sweet spot. You know, slap echo, standing waves of many frequencies, and reflected waves. There are many sound pressure peaks around the room that have much higher SPL than ... | |
| Neutral electronics are a farce... Roger wrote,"geoffkaitWould you settle for whatever distortion you get in the concert hall during a live performance?Its nothing but air which is a linear transfer medium.If it did exactly the same thing in your home would you say "this is just li... | |
| Neutral electronics are a farce... "^^ of course, there is the issue of what is meant by 'zero distortion'."That's true and there is another related issue concerning whether "live" can actually be undistorted. | |
| Has anyone heard the new North American products preamp and amp? Tbg wrote,"Roger, this is a good explanation, but I suspect it is over gdhall's head."That argument, "I'm smart and you're stupid" is one way to try and win arguments. That's the ugly sibling of, "I have more than fifty years in audio so I must b... | |
