I have the Mayware formula IV mated with a Denon DL-S1 on a Luxman PD121 (this is a Micro Seiki heavy aluminum plinth). I replaced the arm board with solid maple and swapped the mat with a copper one.
I have compared this with a Lenco rebuild with a VPI 12.5 - Denon DLS1. This is not a true A-B comparison, though, I am incredibly pleased with the Mayware. I didn't think it would compete with the Lenco combination. But the Mayware holds its own. Through complex passages, it has great clarity and reproduces the complex character of acoustic instruments (classical music). Vocal harmonies of the Mills Brothers are crystal clear and well focused. The voices sound like they are in the listening room.
I plan on replacing the tonearm wires and the headshell. But, for $300 it competes well above its price level. I would like to do a true comparison on the same Luxman table. Though, I don't feel the need.
I do not use the anti skate feature on the arm Mayware. I just let the weight sit on the right side with no stress on the thread.
