Graham Phantom Elite vs. AS Aquilar

@wrm57 ,

I tried to warn you about that. Read my first post. The Technics is a well made battle ship but it is defective in a number of respects. It's vertical bearing is above record level leading to increased warp wow, it is a stable balance arm and the best arms are neutral balance. Neutral balance arms do not change VTF with elevation. It has two sets of unnecessary contacts, one at the head shell and another at the output side of the arm. The best arms have a single wire cartridge clip to RCA or XLR. "S" shaped arms add unnecessary mass and inertia to an arm, straight wands only! The less inertia the better the arm tracks. 

@lewm , are your eyes so bad you can't set VTA? I can get it to 93 degrees with a 3 X 5 file card with a 93 degree angle drawn on it and a hand held magnifier. VTA towers are an additional device with potential laxity interfering with the rigid connection between the arm and the platter. Without that connection any resonance in the arm is reflected right back to the cartridge. 

@rauliruegas, thank you for the detailed post with the suggestion for servicing. I had read that TNT review already and noted the specialist in Germany. I have reached out to him via email for more info. It appears that he uses stainless steel bearings for replacements, which, along with ceramic bearings, you don’t like. Is this because alternatives dramatically change the sound? Not sure there are options are out there for restoring the EPA-100 with ruby bearings.

@mijostyn, you are such a thorough-going tonearm Platonist, eyes (and ears) fixed on the ideal! But as you suggested in the Lofgren B discussion in another thread, these ideal characteristics perhaps make no discernible difference in listening beyond the psychological. I’m really not so concerned about the neutral v static balance issue. It comes into practical play primarily with warps. I flatten all warps with an Orb. And I like being able to swap in headshells and cartridges easily on some of my arms, and even phono cables, so I’m willing to accept the heresies that come with this convenience. I’ve had arms with captive cables that I’ve liked less.

These issues are not theory. They all contribute to the performance of the arm. Whether or not you can hear the difference, frankly, means nothing. With any one issue you may not be able to discern a difference, but put them all together and you are more likely to hear a difference or not. Some people's hearing is more influenced by what they see then sound waves in air. 

I can not play with or listen to every tonearm on planet earth. So, I have to pick and choose based on the arm's design and reputation. I am more likely to get an arm that works well by paying attention to design principles.  

@mijostyn, I hear you, I really do. And I admire the rigor of your approach, and largely agree with—and benefit from—your conclusions. So keep ‘em coming!

Dear @mijostyn  :  With wich cartridges did you already tested the EPA 100 and compared against wich tonearms?

Theory is just that theory and is good but it's not all down there. As the EPA 100 other vintage tonearms as the MAX 237 or the GST 801 were and are great tonearms even if goes against that theory and in the past almost all great tonearms came with removable headshell, yes a trade-off but if you have several cartridges then that´s a welcomed trade-off because we can mate each cartroidge to its best headshell " couple ".

Nothing is perfect and you already know that.
