Rega P3-24, Pro-Ject RM-5, or Technics 1200?


I'm in the market for a turntable and have been looking at the Rega P3-24 and the Pro-Ject RM-5. I was a DJ, so I already have 2 Technics SL-1200 MK2s, but based on things I'd read elsewhere assumed that these would never really be "hi-fi". I came to Audiogon to see what people had to say about the Rega and Pro-Ject tables and was surprised to find quite a few postings saying that the 1200s could sound as good or better than either of these. Most of these posts discuss KAB modified 1200s. I've already got the tables, can I get the modifications made to one of my existing tables, and which mods would folks suggest? Also, if people think this is the route to go, what cartridge would you suggest? If this isn't the route to go, which table would you suggest?

Just for reference, here's my current system:
- NuForce IA-7 integrated amp
- Reference 3A MM DeCapo speakers
- Arcam CD36 CD Player
- Bellari Moving Magnet Tube Phono Preamp

Thanks for your suggestions!

Hey folks - thanks for all the responses. Based on suggestions, I think I'm going to start off by changing to a Sumiko Headshell and get the Audio Technica AT150MLX cartridge.

Then I'll get the KAB fluid damper and the Isonoe footers. I'm not sure about the tonearm rewire, as my tables are so old I don't have the original boxes to ship to KAB, and I'm not sure that's something I can do myself.

In fact, after reading through various posts on here, I'm worried about just swapping out the headshell and cartridge. What kind of tools am I going to need to get this set up properly? I see mentions of stylus force gauges, protractors, etc. This is all a new process to me. It's beginning to sound more complicated than I thought it would be and I want to make sure I'm going to be able to pull it off ;-)

Tvad, that is an excellent question. Adam18 has basically answered it for me, as well, thanks. I have heard that if you want to try a different cartridge on a Rega, you have to buy their spacers to do so, as Rega's cartridges are not quite the standard size. Another reason for the after market stuff is that in this hobby, as I am sure you are aware, there are a great many people much more interested in the equipment than the music, and these folks usually can't leave well enough alone, they have to keep messing with stuff.

I should emphasize that this is NOT a criticism of the great many DIYers who use musical reasons as the basis for their experiments. I would love to build my own SET amp, for instance, or my own horn speakers like my uncle did, if I had any engineering skills whatsoever. Maybe after I retire, but that's a long way off yet. In the meantime, I figure that the manufacturer knows alot more about it than I do, so I will not mess with my Rega setup.

Trust your ears and don't care about professors around that speak without to have listened
I have owned many super turtables starting from the first Transcriptor , Thorens , Linn Sondek , Michell , passing through Well Tempered Reference and my latest SME20/a and now I'm enjoing a SL1210 MKII cos I'm waiting to find a super TT
Well, the SL1200 is so good I can wait long time ...
Obviously you should be able to set up a SL1200 at its best .. and not for disco!
