I used to have an original AR table I had modified to accept another make arm. The same as a Linn Sondek, just not as well made ;-)! I put a Formula 4 uni-pivot on it, which I wouldn't do now---the AR's suspension was very "loose", which made the uni-pivot too unstable IMO.
By the way, the Audiomods arm is NOT a modified Rega, though Jeff does use the new Rega 303 arm tube (the only Rega part, other than the cueing lever), which he very heavily modifies. There are Audiomods owners who also have SME's, Helius Omega's, etc., and find it competitive with them. I would much rather have one than a mass-produced arm with an S-shaped tube and removable headshell, but that's just me. The Audiomods Classic Arm is only 455 British Pounds ($708 at the moment), and is completely hand machined from blocks of billet aluminum by a master machinist, one-by-one, to your specifications, the mass of the arm adjustable to meet the effective mass needs of your cartridge. An outrageous bargain!
