McIntosh MT5 or VPI Prime Scout turntable

My first reaction is I thought McIntosh turntables were made by Clear Audio - I would research Clear Audio turntables as when you add another layer you may add cost.

I would audition the Luxman and the McIntosh side by side.  I've owned McIntosh pre and power and personally I prefer Luxman's clarity though let me be clear I enjoyed listening to music on my McIntosh system for hours and hours at a time!

I’ve owned a Mac MT5 for years now and it’s a fantastic machine. The fact that some of it is produced by Clearaudio was a selling point for me. They make some of the best turntables in the world. Accompanied with Mac gear the MT5 is a great addition. I put on an Ortofon Cadenza Black cart and it’s fantastic sounding!

Instead of changing TTs why not try an external phono stage first like an EQ500?

Phono stage can make a big difference.

Besides a phono stage you may also try changing cartridges. What's your current cartridge.
