Victor TT 101 vs TT 81

I am aware of some of the differences regarding the motors of these two units, but I was wondering if anyone had insights as to the differences in sound (if any) and the differences in reliability (I'm guessing the 81 being simpler might be more reliable, however, it seems to have the better motor).  Any info will be appreciated.

If you are aware of some of the slight differences in specs between them, I think the main practical differences are the 'coreless' motor of the TT-101 and its complex ability to adjust pitch in 1Hz increments.
I have both units

and cannot honestly say that I can hear the differences in sound.
For the ease of repair and ownership....I would recommend to anyone contemplating buying, to find a good TT-81. You won't be disappointed.

I have a TT-101 for roughly 30 years, just mounted it in a new custom base with a 12" VPI 3D printed arm and it sounds amazing.  Highly recommended and it does hold up if not abused. I have never had an issue with it.

Hi Harry,
Can you describe your "custom base" and what you feel it does for the sound of the TT-101?

I used the Classic Direct base which is 5/8" aluminum, 1/8" steel, MDF, and a walnut outer finish.  Really works well and has the resonance structure of a sausage hitting a pillow.

Thanks for the info Halcro and HW.  

Halcro, to be honest, I have a bias towards coreless design (interesting you find it difficult to differentiate from the two...food for thought), but was concerned about the complexity of the 101 (more things that could go wrong).  Reading from your prior posts, I realize the importance of changing the caps and re-soldering the old solder joints (specially when troubles surface regarding the latter).  Are there any parts you think are particularly important to acquire as spares?

HW, that is a very positive recommendation from you and the custom base is quite interesting.  Did you try it nude with metal pillars/feet?  If yes, was there any advantage or disadvantage to using your custom base?
