I ordered today from them the 6C33C dumpers and spoke with someone in there. Forthrightly speaking it sounded kind of ugly when the guy on the phone insisted to call the pads as the “anti-vibration instruments”. BTW, I did ask him directly if there i...

[quote user="Romy the Cat"]Jessie’s comments about my idea to position midbass straight horns from basement, upper- firing and his warning that the horn will get converted into a giant garbage can made me to think. I did not think about it but it is ...

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...

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...

[quote user="Paul S"]Anthony, it sounds like you have given a lot of thought to damping structural vibration. I was referring to the electro-magnetic fields thrown by transformers, and - based on my view of your perspective drawings - I was wonderi...

For me the "delta" with the newer Hal-O dampers was in the direction of increased clarity. One example is in vocals, where consonant sounds like "f" and "th" were much more realistic (my "s" and "sh" were already pretty good.) Beyond these typically...

The basically the same tubes. The 6E5P has own unit pins layout with heaters connected across the tube – very moronic in my view and it does not allow twisting the AC filament wires to the very end. The 6E6P has a common pins layout that most of west...

I am not sure what rectifier the 2A3 SET uses. Mine uses the GZ37. The best regarded is usually the Mullard NOS. I have used that for years.
Recently I was on the kick of listening to the vibration of tubes and I came across a dirt cheap tube fr...

Robert, Yes, of cause I understand it. The problem is that when I laid down the pipes under the midbass horns there was no larger diameter available then 6” pipes, there was no more clearance under the mouth. So, my listening room has two 6” pipes an...

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...

[quote user="Romy the Cat"]
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...

[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...

[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...

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...

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="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...

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="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...

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...
