Your correct, nothing you say will change my opinion

I've used MC cartridges for years on my MC killer with no adverse effects.
My 124 is mounted on a CLD (controlled layered Damped) Plinth, which brings out the detail and SLAM that idlers are known for. I rebuilt the motor myself with close tolerances, allowing it to acquire speed within 2 seconds. The sintered bronze spindle bearings were machined smaller than tolerance, I then polished them on a lathe to + .002". My idler wheel is also machined to less than .005" variances, thus no audible rumble.
So what I'm saying is, the broad statement that idlers are rumbly compared to belts is exaggerated to say the least.
My stuff sounds great to me after 30++ years of tinkering, and no, my system doesn't go down in the 20 Hz. My home theater does though!!
My apologies for thread crapping, my opinion stands that the 160 is a very good choice for your budget.
