TW Acustic three motor unit

Since two weeks I have on loan three motor pad from my friends Black Night turntable. Today I have to return it and just switched back to my stock single motor.

When I first runned three motor pad I felt advantages and disadvantages of this unit. The sound become better but not in each aspect.

With three motor pad the bas was deeper and better separated. The attack of large drums in final of Mahler first symphony was simply spectacular. Three motor unit rocks on complex passages. Overal the sound become more dense, better separated and defined but there is a big but...
With three motor pad the airness and openess of the sound decreased and some "music flow" has gone.
The sound become more audiophile correct but a bit less musical at the same time.

Can you share your experience with AC1 vs. AC3 vs. BN motor?
Does anybody preffered AC1 instead BN motor?

I am puzzled.

Keep the AC-1 if you prefer it over the BN motor.

I preferred the original TW Acustik power supply to the BN battery unit. I found the battery unit was too smooth and lost pace rhythm and timing compared to the stk AC-3 unit.

cheers

I agree with the above when I went from my AC3 to Black Knight table, I was fooled at first just because of my new purchase BLING "being the Black Knight" feeling it should be superior at more than double the price but quickly realized after sometime in usage wasn't and in the end sold it.

In my opinion BN mystery is hidden in copper platter but beside the copper platter four feets instead three, aluminium chassis with only 25 mm thick derlin plintch and three motor unit in one chousing are disputable changes to original AC-3.

I have in my AC battery power supply, BN feets and BN platter and I stuck when tried to add BN motor unit.

Funny, my 35 year old Exclusive P3 gets more use than my TW AC-3 due to the better sound.

Milimetr, how did you make sure that you had the same amount of belt tension when comparing the one vs three motors. After dusting or moving the motor the Feickert tool is used to place it back to the same distance with in one or two millimeters.

From playing around with other belt materials and motor distances with the original belt one can hear differences in these things alone. Its not hard to kill the airiness with too much tension. Dampening is different
