70’s rock pressings. Witch equipment deserve?

chakster, There were major differences in quality between the genres. Motown made the worse pressings ever. Rock and Jazz are hit and miss. Classical was handily the best.  Fortunately, those us with turntables have become a lot more discriminating and are willing to pay for top notch pressings. Records are now better than ever. 
1000 records is still a whole lot. Buy the darn turntable and get to it. You have a lot of listening to do.  

"expensive capsule/phonopreamp"

Any record will always sound more convincing with a better cartridge. A cartridge will always sound nicer with a better phonostage. The price doesn't dictate what your ears will like. 

HI,
70 s pressings include a lot of masterworks, so get the best you can afford. All of the prog bands had many great recordings on Island, TFCL, Deram, Chrysalis, Manticore, Virgin, Harvest....

My vinyl collection is the same era of music and style as yours and the better the table, arm cartridge and phono stage, the better sound you will get.  I started off with an inexpensive Rega Planar 3 with a Linn K9 MM cartridge and moved up a few times and every time I got better and better sound.  It all boils down to how much you are willing to invest.

It has nothing to do with the genre, it depends on the pressing pant, mastering of each release and country/region where it was pressed. It is also depends on the recording itself, because not every band can make a proper recording.

Japanese pressing from the 70s (from the original master tapes) is the best for all genres.

Classical was handily the best.

I don’t listen to classical music and i’m not into rock music.

Reissues are not better at all, in 99% they are worst ever, because they are digitally remastered, if you’re lucky they are made from an old master tapes. But comparing to the best original (vintage) pressing those reissues are very bad (most of them).

I don’t care about new records, as the OP i collect vintage vinyl, mainly from the 70’s.

When someone looking for turntable, speaker, phono stage, cartridges it is for all genres of music. The rest is personal preferences and just speculations.
