Paying extra for an HDCD decoder, with limited title availability seems not very wise when you can just listen to xrCD (granted, with limited title availabitlity, too) and not pay a dime more. Well, life is not perfect. Bring on the flames. I am wearing Nomex underwear today. Francisco. NO FLAMES but there are several HDCD's on the market.

Re: MD: More on CD vs. MD Sound Quality
Hello ALL Several good posts along this thread (once again) but I like this one most as it points out the not so obvious things that can go wrong...even the slightest of analog components (never mind the digital) can make a very noticeable difference! Let me add that anyone that hears a difference on regular quality home equipment DEFINITELY has a problem somewhere in their MD system. You should not ever be able to hear any difference "normally" though as some have pointed out there may be that rare classical track that just will not record right. My point is that if you are always hearing a difference no matter what you are recording, then you have a problem. Possible problems can include expecting too much from a portable! Never expect a portable to match a good home deck as you would not expect a portable cassette to match a high end home deck either. After all it IS the cassette we are talking about replacing here, NOT CD. Newer CD decks also have the 20 bit (and some with 24 bit) resolution so the analogy on that issue isn't totally accurate (although I believe all computer burners are still just 16 bit so still a good point). In any case there is not a better replacement yet for audio in my mind. I do not expect my MD stuff to replace CD, just compliment it. Many have said that DAT (or even very high end cassette) is better and while this may be true for VERY high end gear costing much more, it does not remain true over time. Even a digital tape is going to experience wear and loose quality in time. HERE is the big advantage of MD! It is going to sound as good after 1 playings as it did the first time. And by the way, if you have not been to www.musicmixers.com/mall in a while check out the new look and prices. Please let me know what you think. Am still busy as heck changing and adding stuff as I go, so sign up for the mailing list while there to get notified of the monthly specials (we do not spam and never send more than 2 mails in a month).

Using the system you described, the problem with the sound probably has very little to do with the MD format. The 530 has crappy converters. So this may be the reason why my recordings and playbacks with Sony's MZ-R 70 seem so low on quality. If ATRAC is the same in every machine, the difference comes from what is before and after this compression, hence the need to know what we buy (this is very difficult to know, indeed). By the way, is this what the ATRAC type R does (as Matt would suggest)?

Newer CD decks also have the 20 bit (and some with 24 bit) resolution so the analogy on that issue isn't totally accurate (although I believe all computer burners are still just 16 bit so still a good point). The CD, as originally developed by Philips and Sony, only has enough bits for 16-bit resolution, but Pacific Microsonics came up with a way to hide 4 more bits in the audio to allow 20-bit resolution. Problem is, very few CDs are recorded this way, so practically all discs are recorded at 16-bit resolution. Also, there are not very many CD players that have the Pacific Microsonics decoder, so most decks only extract 16-bit resolution. Many CD decks now output 20 or even 24 bits. This allows them to more accurately represent the output of high precison DSP calculations in the digital anti-alias filter, but in practically all players, the input to the anti-alias filter is 16-bits. Contrast this with MD, where the format natively defines 20-bit resolution (16-bits + 4-bits scale factor). S/PDIF allows up to 24-bits. In fact, if you look at it on the 'scope and count bits, there are 32-bits, but the other 8 are for framing and non-audio. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

RE: MD: More on CD vs. MD Sound Quality
My recomendation, if you want a very good DAC, is to use an outboard DAC where all of the power parameters have been optimized for the best audio performance. The built in DACs in many CD/MD decks, while better than portables, are no match for esoteric, high-end outboard DACs. According to the Revue du Son (December 1999), some components found in high end MD decks are similar (or identical) to the ones used in high end CD players (much more expensive than MD decks), and even in SACD players: 24 bit digital filters, noise shapers, 24 bit DACs, etc. But this does not answer the question about the ATRAC DSP type R from Sony. What does it do exactly? I guess it is similar to the Rec and Play DRIVE system by Kenwood or to similar systems by Sharp, e.g., unless you prove me wrong!

Re: MD: More on CD vs. MD Sound Quality
wow, this story goes endless. Let me tell you my experiences and opinions. I was doing A/B test some times ago with a friend of mine. We've been doing recording of the same song, Jazz devil by Barry Adamson. The units were Sony 530 MD, and the rest was nothing special, Akai amp, Sony 330 CD, small Tannoy's and some cheaper Van Den Hull speaker cables and interconnects. The connection was analogue. The results weren't so impressive. In fact, MD copy has the following characteristics: obviously less dynamics, very poor bass and Jazz devil has plenty of it), narrow stereo image, and in general flatten sound picture. We've been doing this again with the other types of music with the same results. It doesn't put me off of buying MD, but ( maybe it hurts somebody on this list), MD is not so impressive music format. Yes, you need a little bit of extra concentration to spot all the differences, but believe me, it's not so hard anyway. Don't get me wrong, I love MD, and for a casual listening at home ( especially if you're using PC as a sound source), in car, while jogging and riding a bike, it's a great format. But, for a critical listening at home, it is simply not up to the CD standards. MD simply isn't an ultimate listening experience; its advantages are countless, but don't be so uncritical, CD is still fairly better format.

But is it not compression per say. To really have done ATRAC correctly, it should have been variable. That is some "files" will contain more inaudible data than others. A perfect ATRAC scheme would not predict the total amount of music that each MD could hold. It would depend upon what was not needed. This type of situation is really not that uncommon. A CDR claims to hold 650 MB of data (minus that used for formatting). However if you use your CDR to back up files using data compression, there is no way of knowing in advance how much you can fit on a disc. It will vary from disc to disc depending upon the compressibility of each file. But ATRAC is bit wise reduction, not compression. It relies on the theory that 80% of the data on a CD is not needed to reproduce the music. By using an exact ratio, they are not taking into account the variables of different music. For example something recorded which does not have a significant difference between the loudest passage and the quietest should be easiest to process with the least amount of detectable difference between the original and the digital copy. These discussions can only be applied to digital transfers since. Analog creates a much more complex number of variables.

Re: MD: More on CD vs. MD Sound Quality
I'm looking for a portable MD player (+/- recorder) with both LP modes -and- and very good DAC. I think the DAC in my Sony MZ-R50 is holding back the fidelity of the music (based on tests along the lines Francis was suggesting). "Portable" and "very good DAC" are mutually exclusive for technical reasons. In portable electronic devices, low power consumption is the *primary* design issue since it must at relatively low voltages and currents to get reasonable battery life without having a huge battery pack. Very good DACs and analog stages require higher voltage and current than is avaiable from batteries. Many home CD/MD players use bipolar 5 voltage power for the analog section. Better home stereo equipment uses bipolar 15 volt or even 24 volt supplies. Also, to get the lowest noise, low impedence circuits, requiring high current are used. None of this stuff is possible in a battery powered portable device. Another consideration is interstage coupling capacitors. To get good low frequency amplitude and phase response, large value capacitors must be used. These are often physically too large for a poratable unit. Of course, the best approach is to use DC coupling with servo amplifiers to cancel the offset, but only very esoteric audio equipment implements the complex circuitry required to pull this off sucessfully. My recomendation, if you want a very good DAC, is to use an outboard DAC where all of the power parameters have been optimized for the best audio performance. The built in DACs in many CD/MD decks, while better than portables, are no match for esoteric, high-end outboard DACs. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

The 530 has crappy converters. What you have done is take the CD and put it through a digital to analog converter. The signal then has to be converted from analog back to PCM digital by putting it through a digital to analog converter. The PCM is processed with ATRAC. The ATRAC signal is decoded to PCM again and then the digital signal is once again converted to analog by putting it through a digital to analog converter. High quality converters alone can cost thousands of dollars. Probably more than the entire system that you described. It is impossible to evaluate the sound quality of MD without using much better equipment and keeping everything digital. If the MD had been copied digitally (even if the equipment was just so, so), there would be no converter in between the CD and MD. The only converter would be the final digital to analog (here the better the converter the better the quality of the sound you would hear). The better the quality of the MD playback equipment and hence the DAC, the closer to the original CD the MD would sound. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

So you could probably fit 2 hours or so of music on an MD. At $1.50, considering the alternatives, that seems like a pretty good deal to me. BTW, I was just at my local Circuit City and didn't see one portable MD recorder or player! They had a 15 pack of Fuji MDs for $30. I also saw some strange brand (Classic??) of portable CD player that also played MP3 CDs and had 105 second buffer for $99.00! The unit was kind of bulky (thick) and only had an analog line out.

You are misinterpreting my statement. "closer to the original can mean beyond the ability of the human ear to tell the difference. And what we are talking about, a cheap way to record music or high end ES series MDs of 600-1000 $ range? And they do the same; it's still 5:1 compression. The same applies to the other mediums as well, you need a better CD player to hear your CDs better. What's the point of having 100 $ CD player and 1000 $ MD recorder who provided "closer to the original CD sound" of 100 $ CD player??? One of the fundamental things you have wrong is this 5 to one compression. It is not compression. If set up correctly 80% of the digital information on a CD not heard by the human ear. Don't confuse bit wise reduction with compression. Compress schemes pose limits, like FM cutting off frequencies above 15,000 CPS. ATRAC does not do this. That the set up program on Windows 98. It is only about 30 MB. Yet when all of the Cabs are opened, you will have several hundred MB of space used up on your hard drive.

RE: MD: More on CD vs. MD Sound Quality
From my experience, the quality difference is undeniable, even if I mostly listen to rock music (in the broader sense). I cannot say 'this has changed" or "I cannot hear something that is on CD", but something is changed as far as the musicality, sound clarity or richness are concerned. Maybe the recorder and player are to be blamed for this. I own a portable Sony MZ-R70. The sound is acceptable with earphones, because there isn't any direct comparison, but played on my stereo system (NAD amplifier + Celestion Ditton 66 speakers), it is really disapointing. I am now considering purchasing a MD deck to have better quality both when recording and playing minidiscs. Any good recommendations? I am not particularly fond of Sony equipment. I've read from reviews that -Kenwood's DMF-9020 is top-class (What Hi-Fi?, UK) and Spitzenklasse (Audio, Germany). Any good or bad experience with this deck? Are there any other better machine as far as the sound quality is concerned?

MD: More on CD vs. MD Sound Quality
I'm catching up on a week's worth of digests, so bear with me for weighing in late. Larry had stated that it was his belief that most people cannot hear the differences in sound, that it was more psychological. Don replied that he does not subscribe to the notion that people can hear differences. I will grant that there is a psychological inclination to hear differences. We know there is compression going on, so there must be a difference. That being said, I am here to tell you that in some cases, the differences are there and noticeable - even when not listening for them. I don't know how many people on the list listen to classical music. I have made a number of recordings, Holst's Song of the Night, a piece for violin and orchestra by Respighi and a piece by Massenet for piano and either oboe or bassoon - can't remember are three examples, in which there were moments when the ATRAC just could not encode the music properly. On the first two examples, the problem occurred during an swell in the orchestra. In the third, it was low chord on the piano. Each time, the music came across for a second or two as a noise, sort of as if someone were blowing across a microphone. In none of these cases was I looking for, or expecting to hear, a difference. I heard them while listening casually, and then went back to double check. No need to do an A-B (no facility either), this was plainly not a musical sound. I have never noticed any significant differences in jazz or rock. The differences are there in some of the more difficult classical music recordings. Unless you have done this, I don't think you can call your opinion informed. That being said, I still love MD. In those cases where the MD has had a problem, I just made a CDr. In other cases, the MD is fine. Does a great job on vocals and choirs too. James __ Do You Yahoo!?
