Fidelity Research FR-64 vs. FR-54

Dear @chakster : Why is crazy?  when in the day by day life in a dialogue between two gentlemans and when are talking on any topic/subject always between that " talking " they touch other alternative issues and at the end several times finished " talking " on a very different topic. That's the way the human beens are.

The audio forums, its real utility, is precesily that: that in a thread we talk on many relationed subjects that for many of us are part of each one audio learning curve.
This is the way I learned and still I do it. This is the way to confirm if I'm rigth or wrong. This the way I can discern my self about any single audio subject and that way is the one that permits me to test and start evaluations that I never imagine I had to do it.

Crazy?, not really. I think is a strict audiophile's necessity to grow-up.


Regards and enjoy the music,
R.

yeah, first it's was a topic, then it became a dialogue between 3-4 gentelments, on normal forums it's called off topic or free speach. I think we have no moderation here anymore, but something like "free speach thread" would be nice to remove stuff like that right there from each topics when people go too far from the original question. Actually i don't care, just a thoughts. Playin records from another room subject has nothing to do with FR54 vs.FR64 tonearms anyway.  

Dear @thekong : Look, I never said that air borne does not produce vibrations/distortions. In the other side, I already did it that test.

Dear Raul, great! So, did you hearing complete silent or a faint sound of music through the headphone in that test?

The bass waves of fundamental notes in the 1812 cannon shots ( 8hz-16 hz. ) through a home system can't impact your chest because are not " builded, yet. . Are to big waves ( a little different in an open enviroment as how those shots were recorded. I have not this live experience, so I can't tell you about. ). These big waves normally came from the floor up and depending of that system/room handling is how you will feel it. If you can feel it in your chest then what you are feeling could be some of the overtones distorted by that bad system/room management. Those overtones came developed from the fundamental notes. Maybe your system can't even ( electronics. ) reproduce those frequencies or your speakers and that's why you can't live today my experiences.

Your theory about big waves can’t be “build” in a relatively small room (as compared to open space) just can’t be true. As bass is more or less pressure waves, it would expanded in all directions. As I learned from Discovery Channel (or was that National Geographic?) that many of the hand-held antitank missiles cannot be fire within a house, as that would create over pressure which could hurt/kill the operator. So, you theory of not feeling the pressure because of the relatively small room is just false.

Actually, bass or not, any sound wave, including the treble, would impact the turntable system and create feedback and, therefore, distortion. Only that the bass, which carries more energy, would have a bigger affect. You just can't fight the physics.

You, me and every one need to have facts on hand not theories or just opinions on what we think about. Where are those facts?: FIRST HAND EXPERIENCES IN SIMILAR CONDITIONS.

Well, I assume you have not fire a live cannon in your room, most likely not even a bass drum, so how do you know they could not “build” the pressure in a room? Where are those facts?

Recently, the movie "Heist", with Robert DeNiro et al, was shown on one of my cable channels.  In that movie, DeNiro cracks an otherwise impregnable safe by first drilling a hole in the top, then filling the safe with water.  He then drops a small explosive charge into the water-filled, sealed safe.  This results in the bursting of the safe due to the lack of compressibility of water, much as you say would happen if you fired off an explosive in a small house.  But I think there is a difference between dissipating the energy and hearing the extreme low bass frequencies.  I think you do need "space" in order to propagate the frequencies as audible sound, where the wave length exceeds the dimensions of the closed environment.  So, in a small room, you might get the worst of both worlds: unwanted energy that can feed back upon the equipment and failure to reproduce the sound as music.

Lewm/The Kong,
I agree that some of the claims of flat response in room on this forum are doubtful where the listening room is small. I have even seen one claim on this site that a system using pair of Acoustats in a room not much bigger than a broom closet can reproduce bass flat down to 20hz in room. Furthermore full range systems often "overdrive" small rooms. ( For Rauls benefit, this is not conjecture, I have learned this from experience in setting up 100's of systems ). In my own case my listening room is 37'x15' with a high stud ceiling and the benefits when shifting the system from a smaller medium sized room were obvious.
Similar experiences shifting turntables around the room relative to the speaker position have resulted in reduced distortion in my experience - this is not rocket science - it is simply finding the least resonant environment for positioning a mechanical device that measures minute groove modulations in motion. In my experience locating the TT between the speakers is second only to "behind the speaker" or corner location  in inducing distortion into the playback.
