Schroeder vs. Triplanar VII Sonic Differences

You guys will probably think I'm crazy, but I'm planning on sandwiching a few of my extremely warped specimens between a couple pieces of plywood and setting a 50lb. weight on top and leaving them for several months. Naturally, these records aren't prime collectors items, but I'm hoping this works well enough to salvage a Doors first album and U2's Joshua Tree. Both are so bad I can't play them now anyway.

I'm sure the commercial product is faster, safer, less work, etc.

Cello,

Can you add anymore to the sonic differences of htese brands? Especially the difference between the Triplanar and the Schroeder Model 2 or DPS.

thanks!

The unit is the Air Tight(of this I'm pretty sure).It lists at about two grand,and I believe is carried by a variety of places,like Music Direct,or Acoustic sounds.

The reason it originally interested me(remember I put out a thread,vying for some kind of chip-in,which is really not a great idea),was because it IS very reliable,and repeatable.So,you have no worries about flattening out expensive/rare discs.This guy has flattened everything from rare,collectible early mono,to Decca Wide Bands,to the rarest EMI's.Plenty of POP music too.He is a "serious" hobbyist(ya know--with multiple arms,and a cartridge salon,consisting of the Titan,mono and stereo,as well as the Koetsu Coral Stone).

I have noticed some other manufacturers(like Clearaudio)offering these flatteners,but the pricing seems to be getting rediculous(as in too high).

I have always been surprised as to why something like this type of flattening unit has not really caught on,as much as it should have.More "local hobbyists" should chip-in on one,or even a dealer could offer the service.It seems to be a great accessory,if you have a large lp collection,or are a very active collector.The "bit" with the heated glass "Rube Goldbergs" never appealed.

The only caveat would be,after you've flattened your dozen or so warped discs,the unit could sit around for a long time.Unless one decides to make a few bucks on their friends-:)

Best!

BTW,Dan--I have a mint first pressing of the DOORS first album.Really!I'd be glad to let you "steal it" from me,if you can manage to get me an Allaerts MC Finish -:)

Also,Larry,now that I have your attention(I lost your E-mail address),what is the name of,and where can I get the solo guitar/singer Lp you played for me.You know which one.The guy who composed the tune about Michael Jorden.Your friend Pat gave me an E-mail address for it,but it did not exist.That was one of the things I wanted to discuss with you when your cell was cut off.As well as the possibility of my adding the Townshends.Knowing you are very busy,I don't want to "nudge" you on the phone.

Thanks.

This thread, like so many, has gotten off course. I have owned both the Triplanar and the Schroeder arms. The Triplanar was an early version and the Schroeder was a special version for the Loricraft/Garrard 501 turntable.
I think, however, that the characteristics of the arms endure.

The Triplanar was easy to set up and to adjust VTA. It is very smooth but not as dynamic as the Schroeder. The Schroeder is designed for rigidity and is somewhat difficult to set up. The key variable is the gap between the magnets. VTA is difficult to change reliably.

I don't remember which cartridges I used with the Triplanar. On the Schroeder I used the Allearts MC2 and the Decca Jubilee. Although it was very difficult to optimize the Decca, when I did, I loved the sound.

I now have the Shindo Labs/Garrard 301 which uses what was originally the 12" Ortofon spring loading arm and the Ortofon SPU cartridge. This is all designed to work together and is easy to set up, but VTA is not easily adjusted. As a system, it is the best vinyl I have owned.
