I saw an artist on Youtube doing this.He record every song from his DAW in a (good) vintage cassette recorder(not professionnal),and then record it again from cassette to DAW.

If a person has money and truly wants all analog then I am assuming they are all live musicians being recorded with analog gear (Amplifiers and 6.5 jack plugs).
Therefore if analog with the intent to release an analog album, an LP (Vinyl), then I'd go to a specialist analog studio that has preferably a Neve Desk and a Studer machine with a minimum of new Ampex tapes.

It's digital. If the manufacturers wanted to make an analog piece of equipment, they would have, same for keys.
Get a Prophet 5, Mini-moog, CS-80, OBX, Arp2600 or any keyboard that is not digital and record anything modern without digital interjection then it is truly analog. Otherwise just because it is manufactured that way, then it is alternatively digital trying to emulate analog.
Realistically, if using all digital gear, while analog recorder and desk can certainly do natural harmonic distortion, I'd have to ask why try and make a silk purse from a sow's ear?

Plugins have come close but not close enough - yet.

 

To be quite honest, usually none are used. Tape machines don't really mix well with electronic music extended frequency response, so unless you have a high-end machine in good condition, the "warm analog" sound is basically the machine's inability to retain high frequencies, plus some distortion. Remember back in the day people would pay millions to kill and remove the "kind of alive" because they knew tape messes up their sound. I wouldn't say you really need the sound of a tape on electronic music, unless it's subtle (read: well maintained and setup machine) or for specific distorted effect. For the first you can do plugins and save yourself lots of unnecessary expense and time, for the second you can use an old cassette recorder and you'll get the same kind of distortion.

 

People still use tape for a few reasons; the gel of the saturation on all tracts to blend nicely, not needing to rely as heavily on compression and as well if a client specifically wishes it so.
