Which ones sound better? Cheaper? Smaller? Ain't no wonder cap, ain't no blackgate, just a cap, just what is Wondercap and Black gate magic anyway. these new one sure do seem to be designed for a purpose, http://www.electronicproducts.com/Showpage.asp?Filename=avx.may2006.html
Don't want no stinking caps in my signal path. D.C. coupled only. Don't want no phase shift vs. frequency. Only thing worse is a transformer.
That's not what McIntosh thinks. Don't they still use the 1940's concept of their "auto transfomrer" output on their tube units? Lately McIntosh has been touted in StereoPhile as just wonderful, yet 20 years ago steroPhile Shunned McIntosh. Wonder when some Blose AM-5 are gonna be reviewed in SteroPhile? Now that McIntosh is owned by D&M Denon,Marantz,Boston Acoustics, McIntosh...who do present lotsa ADS for StereoPhile, could there be a strange coincidnece in that? How does StereoPhile determine who gets in the review pages for exposure and visibilty. It is a BUSINESS above all other things. Without money coming in, there is no reviews, there is no ads, there is nothing. WHO decides what gets in the pages? I really do think, the bottom line is to SELL equipment, just like car "review" mags are for, it's all a big advertising function really.
Still it's very entertaining read. I like it. Some of the tweak reviews and absurd M. Fremer reviews on the nonsense equipment, like Zander so overpriced JUNK, in 4 chassis, with 16MM hunks of aluminum housing such piss poor ckts, and he raves about it. FUNNY STUFF. Nothing like a nice Euphoric highy distored REPRODUCTION of music. How is it reproduction if the thing is distorting so badly, adding it's own Euphoria. M. Fremer do you still think carbouretors are better than DIGITAL fuel injection in modern cars? Nothing like nice mechanical ANALOG fuel control, over Digital computerized closed loop control of fuel right? Funny stuff. Entertaining. Even steering in cars is electrical servo motors, VW got rid of hydraulic power steerring pumps (less load on engines) now it's drive by wire, steering and even brakes will get rid of brake fluid, going electric drive by wire baby.
We really don't need these capacitors. We should just use A/D converter, and then apply a digital filter algorithim, then use a D/A converter to drive the following tube circuit. Sales would go way up because everyone (except stereophile readers) knows that digital is the best.
By the way does anybody know where I can buy some digital ready speakers? I can't find them anymore.
This may not be the correct forum for this but you brought it up. These systems use a lot of feedback. How much is too much? Most of the input devices are analog and need to be converted to digital to be proessed by the ECU. Is there a market for improved A/D converters? Using a battery is a good thing but there is an oppertunity for special filters for alternator noise and spark EMI.
An internal combustion engine could be considered digital, it has 4 distinct cycles, RPM is the sampling rate of these 4 cycles? Even the first Edison motion pictures, on film are individual images chopped up in time, playback speed is the sampling rate. Too slow the images suffer, speed up playback to the correct SAMPLING and the images smooth out and appear to be a reproduction of the original event. It's a digital world after all.
Each of these four cycles vary through out their phase. A true digital engine would not work well. Definetly analog.
I bet I could sell someone a "oversample" device for film.
I double sampled each frame for improved resolution.
I was able to get more information than I started with.
Amazing.
