My Hero.......
Point being we were having such fun, vintage loudspeakers are so much more of an interesting topic, than crap-a** Chinese plastic fans, no matter how many you stack together.
The external fan could be dangerous without a guard! Consider this, you're watching porn on your computer, and a connector on the rear of the computer comes loose. So, you rush around to the back, trying to determine the problem. But, your screwdriver, (the Phillips head, silly), is in front. Absent mindedly, you lean over the case, that's when it hits you. As the rush of pain envelopes you, you think, "why me, I was already circumcised".
Oh shoot, I suppose we should go back to reinventing the multi- stage supercharger.
Every speaker cabinet you have this notice on it, "the buck stops here". Correct stereo imaging has less to do with the amplifier than it has to do with the speakers. Precision in manufacture yields identical products. Two identical drivers will be reproducing the common portion of a stereo signal identically, and with that, the "stereo image" will be correctly positioned. Asymetrical driver movement nets phase shift, and time distortion.
The fact of the matter is, the transient response of a correctly manufactured loudspeaker, is the last stage of the reproduction process. Beings as it's mechanical, and not electrical, the laws of physics take over at this point. It's all about precision tolerances, and a massive magnetic motor, that causes 15" cones to move like the diaphragms of a head set. Good drivers accurately trace the signal path, cheap drivers plow out their own impression of it. JBL used to flatly state, "the transient response of our loudspeakers, is unparalleled"? That's about the last time I've seen truth in advertising.
And then there's Enya. As someone who listens avidly to Loreena McKennitt, I don't have the right to snicker at somebody who listens to Enya. I reserve the right to be puzzled though, she has the talent, that's a given, but I just don't get her. Loreena has a better instinct for storyline, along with a better flair for traditional instrumentation. (IMHO)
I would ask this existential question of you, "If a tree isn't killed in the forest, but an eco-freak is there to save it, does this still count as a rescue"?alright i'm going to attempt to save this train wreck of a thread with some more cooling input...

The "RIAA roll off curve", is the only thing that the RIAA ever did that didn't involve litigation. What it amounts to is this, when recording an actual "record", the high frequencies are expanded, onto the disc, then reduced on playback. This is because if the HF was put on the disc at its normal volume, the grooves would be so tiny, the first pass of the stylus would wipe them clean. It's a lousy primitive process at best. I'm guessing that the "sounded awful", was just growing pains. Two inch tape in an 8 track studio recorder @15 ips, really sounds pretty good, there's not an awful of tape hiss, believe it or not. (Given the same magnetic particle size, every time you double the tape speed, the center frequency of the noise goes up one octave. At some point, the hiss wil go ultrasonic, and therefore invisible to the year. (Yes, that was an oxymoron). The net result is this; the master tapes had a much wider dynamic range then the records ever could. Absolute dynamic range of a medium is determined by its noise "floor". You can only reduce the signal so far, then you hit the SN ratio's limitations.okay,okay, I get it...you didn't have to take 6 paragraphs to call me a romantic *****!:haha:
The Nakamichi PA7 and the model 19's are a technological mismatch I agree. The "imaging circuitry" (something perhaps you can expound on) in the PA7 is amazing. whilst listening to my classical, and or my Enya collection <<<<insert snickers here....You can here what row the violinist is sitting in...and what color his tie is.
I do recall though that when CD's first came out, upping the dynamic range from 50db to what? 120db? they sounded like hell. I assume that this was from being remastered from glass or gold masters?
