mister1, you say:
"...There is no way FM signal can camper to CD or record in the quality of sound. Even a strong FM signal contains distortions. This are just rules of Physics..."
i say: you are simply mistaken. i have a hi-end system. retail walue ~$50k (tho i paid far less, ~20% on the dollar, by being a prudent shopper, buying mainly used or close-out.) it's a true full-range system, & extremely revealing. the sound i get from a quality fm station *easily* rivals that of my digital & analog sources. EASILY. i spend a *lot* of my prime listening time listening to fm in the "sweet spot." don't knock what you don't know. sorry you haven't had the pleasure of experiencing it.
then you say:
"...Sum of hi-end tuners cost $2000-$6000. Why bother to pay for them and not to invest in to speakers, CD player or amplifier instead? This is my point..."
i say: yust like anything else, you can overpay for a product. i presently own six tuners that cost $200 or less, & i'd put *any* of 'em up against the magnum dynalab md-108, marantz 10b, day-sequerra reference, linn kremlin, naim nat-01, you name it. their sonics & reception capability are outstanding. my best-sounding tuna cost me $75, after i spent $300 on mods for it. i can only imagine how good the other six could sound if i spent money on mods for those. (i'm seriously considering mods for three of them. one cost me $26, one $175, the other $200.) if someone wants to spend big bucks on a fancy md108 or sequerra, then *let* 'em. in a good rig, w/a quality signal, they will get outstanding sound. even if they insist on using $350k amps that measure poorly... ;~)
