On any USA electrical wiring system, ALL circuits are referenced to and mechanically connected directly to a common ground at all times via the "neutral" wire, which ultimately connects to the grounded bus in the service box. And all UL electronics a...

I thought the Forsell TT was called the AirForce. What happened to them? Are the descendants now called TechDas?
Maybe someone can clarify: what does a TT need to do other than provide freedom from vibration, a place for a tonea...

Actually, when the string section has to play ultra softly, they use a mute or damper on the bridge. This is a device that limits the ability of the bridge to pass the string vibration to the resonant body of the instrument. http://www.youtube.com/wa...

Paul, thanks! I'm quite happy to hear I'm not the only one fighting vibrations in a seemingly dead structures...It takes a lot of thinking to properly isolate and damp vibrations.Not unlike in the complementary problem: reproduction of the audio rang...

Paul, I hear you clearly re wall mount. Well...I have chosen the hard way an occasion to have one, +/- universal solution I could "copy&paste"if I change location. Go through that hell and have it done once and forever. I even ask my daughter to...

Paul, as you write the pendulum effect is unfortnately unavoidable if one wants the levelingfreedome of spikes, so I try to live with that. I looked at Walker...tjaa....$1750 for a record clamp...I also saw how he works on his suspension (look at my ...

I would say that there are advancements where you would get far more unanimity on the progress that had been made than one would do for audio after the development of tape. I don't think anyone would want to go back to cylinders. So there are advance...

Hi N-Set, I am three quarters of the way through assembling the first power supply to power-up stage so I have not tested the "singing" as yet. It is something that I have thought a lot about. First and foremost I wanted a steel skin around the pow...

Some of the DIY "Eastern European"/Slavic systems I "hear" on YouTube seem to have very amazing Tone on "selected cuts". Though this sound is not common, I have achieved and played with it myself, and it is "fragile" in the sense that it rarely (ve...

[quote user="skushino"]ScottL,It looks like the two pics you posted are of different systems, the first being slot loaded PP, and the second (full-system) showing a "traditional" IB. You also seem to be confirming my intuitive hunch of potential sou...

If we look generally at stability from bridges to optical measurement benches, mass has one function - tune resonance or place it outside of the desired passband. Other methods are chosen when we want to convert energy to heat.Do we know what a "ligh...

[quote user="mem916"] Oh, by suspension, I meant the tuned spring suspension that the versa (and many other 'tables) use to isolate the plinth platter, and arm from vibrations coming up through the floor and the stand. I don't think of a platter bear...

[quote user="Paul S"]N-Set, why would you disconnect from the house neutral, unless you are using battery power??? This "neutral" is the "ground" leg of your circuit! The house neutral wire is typically white, and the house ground wire is typically g...

Tube traps are mistakably designed as they tend to deal with a very erroneous assertion that it is possible to feel a listening room with some kind of confused and random bass and then to correct the things with...

Romy If you would thank about what you are building and what it does, you would grasp the concept of my thanking. You have a 7inch hole on your bafflle with your woofer on the back side of it in a sealed box. The only...

[quote user="guy sergeant"] I don't think I'd be tempted to make a back loaded horn to begin with. [/quote]
Yep, it is what it is. The back-loaded horns might have as convoluted back path as Scriabin music is but the sad truth about them is th...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

[quote user="item"]Part of the reason we call our computers 'transports' is to encourage people to think of the number-crunching part of an audio system in the same already familiar terms as a CD player - because all the same things matter: CD tr...

I have a problem with how you are using the english language, Romy. You are using an absolute word (like absolute) to mean something you have invented and it is a relative thing. This for me won't do. I understand more or less what ...

[quote user="drdna"]The question in my mind Romy is: why? I will be interested to hear your comment on what your goal was to learn about your system in introducing these and what the results are. After the extent to which you have describ...

I do not remember which one I used. I remember that I was deciding if to mount them on chassis vs. to have a small board with tube sockets under the chassis and bring the tubes through the chassis. The board mounting is better as it decuples the tube...

enjoy_the_music,
I against all of it as it just does not make sense to me. There is a hypothetical problem and there is a cost-benefit to resolve the problem. There is also a cost of damage that the solution costs if to look at the result from a div...

Okay... I also downloaded the original Milq SET amplifier PDF and have looked at it in detail as well as the 6-channel adaptation (DSET) and I understand where you're going with it... or so I think. In my particular situation, I've owned two pair of ...

The bass traps, the biggest one, have only limited effectiveness on the spectra of interest and usually have much more effectiveness in 2-3 octave above the spectra of interest. This make bass to sound less problematic b...

Congratulations on the construction and installation of your horns. May your pleasure at the results reward your effort and expense. I find their installed appearance even more geometrically striking than anticipated and I suspect now that some o...

OK, I understand now when you talk about suspension and will translate to "bearing". I don't know if it needs to be the turntable or the stand but something needs to be responsible for isolation. I have heard good things about the vibraplane and wo...
