Phono pre for Technics SL-1000R (Esoteric E-02?)

Hi Chakster, you’re right :)
Now i have 2/3 cartridges in my mind for the Technics arm, but in the future my turntable will have three arms with their own cartridges, but this will be in the future. That’s why I think about rhe Esoteric, it has three inputs.

Using 2 turntables with 4 tonearms i have Gold Note PH-10 with two inputs and each input can be set to MM or MC with adjustable gain and loading. This is one of the modern high-nd phono stage i could recommend for use with a turntable with 2 tonearms connected to one phono stage (balanced output is also there if needed). This is solid state phono stage with optional external power supply PSU-10. 

If your line level preamp has many inputs you can buy many phono stages (just like you gonna do with tonearms and cartridges). There are some very modest but high quality phono stages on the market. I like JLTi for example.   

If you have unlimited budget and like Japanese high-end you could try this VIDA.  

If you are headed to three arms and possibly even more carts of unknown type consider a double AudioSpecials Phonolab. (Caveat: I have a bias as I sell this product, so will refrain from subjective comment)

The Phonolab is a twin phono preamp (two preamps configurable for either MC or MM, and can be changed later due to modular card system). Gain and load adjustable. rca + balanced inputs and rca + balanced outputs. The power supply for the Phonolab can power a second Phonolab, giving you 4 inputs and the price for the second Phonolab is less as it's ordered sans ps...
This avoids switching at the input which is preferable.

Best in your search.

I’m using a Luxman EQ500 vacum tube phono preamp, a Hana ML cartridge mounted on a Yamamoto carbon fiber headshell on my Technics SL1000R with excellent results. 

I also use a Luxman EQ-500 for my 3 turntables (cartridges). It’s actually half vacuum tube, half SS but sounds beautiful. I use Jan Allaerts MC1 in each of 2 TTs and a Ortofon cadenza bronze in the 3rd. 🇦🇺

It is not necessary to use ONE phono stage for all your cartridges, especially if you don't know yet which phono stage you like the most. 

It's much better to try at least a few separately, because it can be a Solid State, Tube, Current-Injection, Hybrid .. etc ... and they are all different. Also it can be an MM phono and external SUT or Headamp for your MC cartridges. Nobody knows what you like and no one can tell you what's the best.
