Recommendation for analog set for $700

Latinsamba1, I personally don't think you will get a lot of improvement by upgrading the DAC.

And the more I research, the more I am worried. It seems that a turntable requires a lot of maintenance. It seems the speed may go wrong, it seems it has to be perfectly horizontal, it seems the suspension need to be adjusted ... am I right?

If the answer is yes, is there anything that need less set up or maintenance?

You dont need to get a suspension table, there are plenty of set it and forget it TTs. The Rega RP1 and RP3 and Music Hall are sold ready to go with cart installed.
Speed is not a problem with these entry level tables. You would need to replace the belt after a few years and the speed is so close to spec that as a novice you would never perceive it as off-speed. You can see them at Needle Doctor, they also have a budget TT section.

Lowerider57, Thanks for the clarification!

I see there is a Project Perspective. I like its look. Is it a good unit? Is it one of those set and forget unit?

I'm not familiar with it, but from the photo it looks like it might need suspension adjustments...maybe someone else can answer this question. The PROJECT DEBUT CARBON looks like an easy to use TT.
The "plug and play" TTs have a flat base with a motor underneath and nothing to adjust once the tonearm has been set up.
The point I was making to you was TTs dont have to be a hassle. I have a Linn which needs constant care, but for a first table get something simple...you will still enjoy the vinyl experience.

The Pro-Ject Debut Carbon is a straight forward turntable. All one would have to do is verify all cartridge settings to make sure the settings did not get messed up in shipping. Set the anti-skate weight on the post mount on tonearm, put the belt on the drive platter, mount the full size platter, plug in the cables to a phono section or phono preamp and ta da your up and running.

The Orotophon Red is a good starter cartridge and you can upgrade to the Blue stylus later. If you feel you may want to go with a moving could cart later you may want to get the optional acrylic platter. The meta alloy platter may not allow a MC cartridge to work right.
