Well, I suppose there is always some benefit in taking AC out of many equations. Whether you will notice a difference between the Interspace motor and a DC motor or if any such difference would be discernible, thereby justifying the cost, is debatable, IMHO.
The motor should be dead slient when played, though it will very lightly humm at idle (as desgined). If you can hear it when it spins, other than some very faint belt noise, check all your angles again. If still noisy, I'd suspect a faulty motor and Not will remedy this for you - depending on age, etc.
