Is Rega the easiest turntable to set up....

@OP. Make sure you like the sound of Rega's cartridges as not everyone does. With all due respect I'm not sure that looking for a five minute setup is the best way to spend that amount of money. Any competent dealer will set up the turntable for you and as long as it's a non suspended design, the setup will not change in transit. Technics and Clearaudio are strong competitors in that price range and the Clearaudio's can be had as a package with one of Clearaudio's own cartridges.

When I demo'd the P3 it had a Ortofon Blue.   It sound excellent but I think I remember the dealer saying it needed a shim to accommodate the cartridge height 

Rega tables are likely the best plug and play, particularly if you buy their cart. It is tricky however with other carts as some don’t have VTA adjustments. I must agree with some of the comments. It would not be my only criteria with a 4k$ budget. I personally bought a P10 last year and put it in sale the week after. You get a better table at this price point IMHO and a good audio store will be happy to demo and set it up for you.

Rega  has a particular sound compared to others . So listening test is important

I have Rega NAIA with Apelion2 and I use it as casual TT . I purchased it as it is simple to set it up- No fuss always ready to play- Plug&play

I mostly use Clear audio innovation TT with Davinci cart

and that’s what I enjoy most- letting to instrumental-jazz-vocal

Hope you get chance to go to dealers and listen to different TT

@lewm that is simply not true. The whole concept and science behind Rega turntables is that mass doesn’t reduce vibrations but transfer and store vibrations. It’s quite easily proven. Low mass and extreme stiffness does. Simply throwing more mass at the issue is not the solution. Read up on the science.
