Huh I never knew Hans said it was noisier. I did believe he told me they sound slightly different, and that clients often owned both. I don't think he told me he preferred one over the other, but he did want to sell me a Denon.
The Denon is in a VPI base without an armboard, so I cannot easily move arms onto it. I could move the Acos arm to an SP 10, but would need to order a second arm board for the SB10B3 base, and I have not done that yet. I have used the same cartridges on both tables, and there are minimal differences in the arm and drive units. Personally i would suspect the arm, tone arm wire, and the sprung versus mass loaded bases have more of an effect than the drive units. But that is just my opinion, and I don't have single variable listening experiences to back that up.
