I have noted before that the quietly of sound that I’m getting from FM broadcast, or even from the regular FM transmissions of the regular CDs, is insultingly beautiful and not really compatible with Sound that I get out of my CD and LPs.

It is not about the fact that one of other specific characteristic of sonic reproduction is more interesting with FM but rather that FM has juts presents VERY different sound, radically different in its entirety. I would like to point out again that when I taking about the fact of FM superiorly am not taking about the “better bass”, or “wider soundstage”, or any other typical crapolla. I’m taking about the very deferent sound!

The situation truly could not be described by any other world then “insulting”. I use very primitive, in-house antenna and the few of classical radio stations that I usually listen I receive at no more then 40% of full strength signal, according to the signal-meter on my tuner. I use a consumer-level tuner that is build without any high-end prejudges. So, where this superbly musicals quality of Sound is coming from and why this quality is so munch more interesting then my other source?

A few days age a friend visited my place and after observing what FM was capable of he suggested me to feel a signal form my LP into the line-stage of my tinier and see what happen. If sounds like foolishness, isn’t it? Not so much. Let to think.

A tuner has a demodulator and output gain stage/s. I do not know how good the output gain stage/s in my Sansui TU-X1. I have a schismatic but it hard to approximate the musical qualities looking at this amplifier. Still if the reason of the phenomenal FM musicality is in the output stage of my Sansui then feeding it with eternal signal would be defiantly an interesting experiment. Interesting that I did have few high-end tuners before but none of them reached the same level of “performance differences” that Sansui TU-X1. Is anything spacial with the Sansui output? I do not know the answer but I do not think so.

Perhaps the reason of the FM musicality is because the signal got modulated and demodulated? Perhaps something is in the nature of demodulation that makes the sounds to become Sound? Then it would be interesting to make a high-quality modulator and high-wired feed it to Sansui using my CD for instance as the source. Will I have then this “FM broadcast effect”?  Or perhaps it would be interesting to try a separate modulator-demomodulator……here is where the Dima’ invention of a “perfect” none-digital time delay coming form…

Anyhow, would some of you who are familiar with the subject to elaborate on the secrets of the FM quality?

Another point:  will this “FM quality” be preserveable and transferable if to record sound to a tape. It is not big deal to get the CR-7E or Dragon and try but I really do not want to hassle with tapes again…
