Any thoughts on the Avid Acutus?

Sounds like an expensive lateral move to me.

I don't understand why you are contemplating changing the whole rig! Why not try a different cartridge first to move the sonic signature in the direction you're seeking (assuming that your phono stage is up to the task).

One of the Zyx range (R100 or higher) would be the easy option - they are fashionable currently - so you could try one out and if it's not to your liking you could sell it on without losing too much.

Hello

I think it is more than a lateral move as the Acutus is a much better table and you are also improving your Triplanar a couple of generations.
I would change the table and arm but keep your cart and you will notice the differences.
Moves like this are always expensive for small improvements unfortunately.
If you can do go for it.

How is Acutus "much better"? My guess would be somewhat better bass but what else? I believe this is more a flavor change than a significant upgrade.

Thanks for your thoughts. You bring up some interesting and valid points. One reason for changing the whole rig is that my dealer is selling the Acutus as a demo package deal (it's already setup and ready to go and it's a Triplanar VII not VI)) and will give me a nice trade-in value for for my current rig. Regarding the difference in sound the Acutus has much better bass but also an incredibly low noise floor that allows the music to emanate from a blacker space. It also seems to stage better with greater depth and is more dynamic. The Oracle does have a sweeter midrange and is more forgiving. It may well be a flavor change but if the deal is right I'll probably do it.
