bwcgrx Posted December 14, 2002 Share Posted December 14, 2002 I've recently purchased a Philips SACD-1000 Super Audio CD player. The Philips has a switch on the back for limiting Frequencies to 40Khz or 50Khz. The manual states that 40Khz is a safe frequency cut-off for all equipment. It implies that some amplifiers and speakers can be damaged with the unit set to 50khz. As I understand SACD contains an unusually high amount of ultrasonic noise and this noise can heat up the tweeters voice coils causing potential damage in some speakers. I'm running the 6 channel outs of the Philips into the 6ch inputs on my Denon AVR-3300. The 3300 manual indicates that it will pass frequencies up to 50Khz using these inputs. I would assume the Denon would be capable of handling the higher frequencies. I'm just curious if my Cornwalls, Heresys and my KLF-C7 can handle the higher SACD content ultrasonic noise and all. Interestingly, the Philips is replacing an entry level Sony DVP-NS500v for SACD playback. I've noticed that the NS500v states a potential frequency response up to 100Khz. There is no such frequency limiter switch on the NS500v. If had no apparent problems playing the Sony in my system. Anyone know for sure? Brian C.

jdm56 Posted December 16, 2002 Share Posted December 16, 2002 Brian, The high frequency output from an SACD or DVD-A machine won't hurt your klipsch speakers; They just won't reproduce it! Congrats on the SACD-1000. That's a nice machine. Quote Link to comment Share on other sites More sharing options...
michael hurd Posted December 17, 2002 Share Posted December 17, 2002 Not to mention the beaming effect of very high frequencies ! I don't think that you would hear them anyway, if the tweeters could reproduce them. For one, the wavelengths are so small, that you would have to be in a direct on-axis position to hear them well, unless you have really hard, reflective surfaces in your listening room. Secondly, the average human can hear up to roughly 20,000 hz. Some asthmatics (me included) can hear frequencies up to and above 25,000 hz. I can hear CRT displays, (tv's, computer monitors) running, even from a distance. Just my two cents. I have not heard SACD yet, but it does seem interesting. The only thing I would like is the option of digital outputs ( I know it is not offered ). If you buy an entry level machine, just how good of a DAC are you getting ? Any one that owns SACD's and players please feel free to comment. I would like to know more. Quote Link to comment Share on other sites More sharing options...
bwcgrx Posted December 17, 2002 Author Share Posted December 17, 2002 Michael I purchased a Sony DVD-NS500v from Best Buy back in the summer for $150. For the price it is a very good machine. CD playback is decent and Super Audio CD playback is very good plus DVD-V to boot. The Philips I bought to replace it, SACD-1000, was their flagship SACD unit. It was the first Multi-Channel SACD player in fact. Originally priced at $2000, the Tweeter chain has been blowing them out for $399. The Phillips blows away the Sony in terms of dynamics and lack of digital edge so common in consumer grade digital. However I highly recommend the NS500v for an entry-level foray into the world of SACD. Get the Philips if you can...its Redbook performance is excellent. Pioneer has units that play both SACD and DVD-A. I have a Panasonic DVD-A unit and enjoy it too, although I feel SACD has a bit of an advantage in terms of fidelity. The best SACDs I've found so far tend to be Telarc's DSD recordings. They bring a new level of spaciousness and dynamics that I've never heard from any CD. I keep hearing people complain about no digital outs on SACD and DVD-A players. While they would be nice, I think people think digital out is better just because it is digital. For one thing there are currently only a couple Receivers capable of decoding either format and they use proprietary connections. Most people would have to upgrade their front end just to take advantage of a highres digital output. Most decent front ends have at least one set of multi-channel analog inputs, which bypass internal processing, thus taking the signal directly to the amplifier section. I doubt the fact that Im using analog interconnects adds any appreciable distortion or other artifacts to the sound. It has to go analog at some point before it can be heard. Brian C.

michael hurd Posted December 19, 2002 Share Posted December 19, 2002 SACD is interesting, as well as dvd-audio. I really would like to try a player to see if I could hear a difference or. I don't recall if my receiver has multi-channel analog inputs or not. Also, my amplifier would probably not amplify anything higher than 20,000 hz. For an older power amp, though it sure does sound nice and has more dynamic range than my receiver ( philips pa1200 vs. marantz sr4200 ), plus I really like analog power level meters. Is there a site where I can see the released titles on sacd ? Quote Link to comment Share on other sites More sharing options...
