Great bass from a linear tracking arm?

My tone arm project uses servo controlled captured linear tracking wand, with a laser to adjust the arm for warping and off center pressings, driving the cartridge perfectly though the grooves. eliminating much of the variablility in different pressings. The laser will also detect exact VTA setting for each LP and make real time adjustments should they deviate more than the allowable 1/10 of a degree.

The servo's can be set for the three common High performance stylus tips and any cartridge tracking force. An algorithm "evaluates" the laser gathered information from the LP to assure that the cartridge only sees tracking forces +/- 1/1000th of a gram and detects and corrects mistracking momentum predicted by the cartridges known mass and center of gravity.

My system does not rely on gravity other than to keep the turntable on the stand, this system could theorhetically with a few provisions in the software could play lp's upside down.

Dear Matt: I don't know if I mentioned when I was at your place but before the tonearm " see the commercial light " we want to share with all of you our Essential amplifier design, at least this is what we are planning.

Regards and enjoy the music.

Hi Raul,

Yes, you mentioned the amp, though I thought it would be coming after the tonearm. Either way I hope I have the opportunity to try both of them when the time comes! I am very happy with my Essential 3150, so anything else you and Jose design/build will be a "must try" for me:-). Looking forward to hearing more about them...

D_Edwards - wow, what an ambitious project! I guess anyone who doubted your love for vinyl, because of your good defense of multi-channel surround, will probably want to cut you a little slack if you can make this happen:-). I have so many questions about how it works I don't even know where to start, but it sure sounds like something unique. Want to tell us more...?

I have heard the airtangent on my deck (brinkmann lagrange) - it sounds sublime. However it is limited in the bass even though every thing else is unsurpassable. The bass was the only respect in which the brinkmann arm was better - and the difference was pretty huge.

Hey Matt,

So far its been fun trying something a little different,

I forgot to mention that the best tracking arm/cartridge will usually have subjectively less bass, this is one area (of many) where perfection can be a negative in the perceived sound of the music. All other things being equal, using test records is a must when deciding these things, so that you know where the "bass" is coming from.

back to the arm..

The "arm" isn't really an arm at all it is a module which holds the cartridge and laser assembly (where VTA and and pitch and yaw is monitored. Dual worm drives "drive" the module assembly along the grooves and a servo matrix controls or reacts to the feedback sent by the module.

What we are working on is the material that suspends the cartridge mount module from the control servos and thinking of ways to remove the Frankenstein cosmetics from the assembly. It was my idea but it has taken the great skills of others to even get as far as we have...I can build speakers and amplifiers not laser tracking tt arms. :)
