I ran 2001 on it's first re-release in 1976 ,in both 4 track 35 & 6 track 70, I would actually prefer it in DTS as the cleanliness of the sound would be greatly appreciated! Remember how many 'silent' space scenes there are! The Dolby system will only remove a portion of mag surface noise!!! So, my vote is for DTS. Granted the mag tracks were spectacular, But in this day of 'push button' operators, and many open magnetic field producing devices in the booth, DTS will simply prove to be more reliable and certainly less expensive to release! As of the last few years, ALL Mag striped prints are recorded after processing, MANUALLY! this is an expensive and time consuming job! Not to mention that no two prints are thus mixed alike! So, variables abound! Where a timecode optically printed, and the sound remastered on CD Rom, I can't think Mag could ever touch it for quality!

I agree: 70mm mag is just too expensive today. But, I would politely disagree with with you, John. The best soundtracks I ever heard were with SR-70mm mag. Where I work, we have 4 THX, bi-amped theaters with digital(three SR-D, one DTS.) The digital sounds very good, but mag is (IMHO) better. I admit, I don't know exactly what it is.. a certain clarity, warmth, richness... It's funny how we use words for other senses to describe sound. I understand that if you were to measure all the elements that make up sound (S/N, dynamic range, freq response, IM distortion, etc.) digital would probably have better techinal specifications. But, (consistantly) my ears tell me 70mm mag sounds best. I know a soundtrack may not be reproduced *exactly* perfectly- 70mm may "color" the sound. I only know that it's right- because it sounds best.

AFAIK, the solvents used in magnetic striping are not banned. But new environmental regulations (especially in Southern California) would require massive investment in "scrubbers" and recycling that is not justified by the small volume of striping business. Audio tape, video tape and floppy disks will continue to be made, because the large volumes justify the investment.------------------ John P.

To John Walsh...No offense taken!!! I can only remember when I ran it in straight 35 mag & 70 mag, at that time we had no noise reduction, so I can not fairly compare with SR-70 mag or simular new processes. I can only say that digital would far exceed the track quality of the 1974 prints I ran! I too have always preferred the 'sound' of mag! That's why many of the films I have collected through the years are either straight mag only or mag/opt!For Gordon, I agree that due to scan speed of the mag that the quality is there! And the newer mag oxide coatings are indeed better nowadays, but the vulnerability of the oxide to wear, abuse and magnetic fields leaves the probabilty of a lasting high quality run in the average multi plex very unlikely! How many people take and de-gauss there sprockets, film traps, etc on a regular basis, and how many even have a way to check for magnetism in these items?? I am sure besisdes a few old timers, techs and projectionists, and really serious theatre owners, The average multi plex equipped with 70mm mag isn't even aware of the extra maintenance required! So I still stand on the virtue of digital sound as the best all around way to reproduce with little or no degradation and minimal maintenance! The average audience is not going to hear any difference between mag & digital anyway!! It's only nuts like me that like that stuff including vacuum tube amps!!! Oh well... ------------------ John Eickhof President, Chief Slave Northwest Theatre Equipment Co., Inc. P.O.Box 258 Wendell, ID. 83355-0258 208-536-5489 email: jeickhof@nteequip.com
