Cartridge recommendations

Hi, I have a Thorens TD124 that was sent to Schopper in Switzerland and has every upgrade available that Schopper can do to this turntable including motor upgrade and service, upgraded platters, Schopper chassis plinth and Schopper decoupled armboard etc etc etc; I recently purchased an SME V tonearm for it. As you can see, I have spared no expense to this point; My last step is to pick a suitable cartridge; Looking for recommendations. My first turntable; Thank you.
That`s a hard one, depending on your downstream equipment and personal taste. 
IMO, a wood-bodied Koetsu would be a safe bet.

 At the moment I have a London Decca Reference in my SME V, and it sounds great. But I don`t think that such a idiosyncratic cartridge should come into consideration as your main cartridge.
I won’t necessarily recommend a particular cartridge but instead make a couple observations and ask a couple questions. I was of the school of finding the best cartridge I could afford and sticking with it. I went through a number of different cartridges over several decades, often sticking with a particular brand because of the house "sound." Some of these cartridges- low output moving coils- may require that you have a phono stage that can amplify a very low output signal or use some kind of additional device, like a head amp or step up transformers. So, one question is whether you’ve thought about that.
There is at least one long running thread here about the advantages of moving iron and moving magnet cartridges which have higher output, and in some cases, are older cartridges that are sometimes, not always, cheaper than current state of the art cartridges.
Where am I going with this?
I’ve started to experiment more with the different sound different cartridges bring to the table.
I did buy my first Koetsu very recently and I am smitten with it-- it just fits so well with the rest of my system’s strengths and weaknesses.
Budget? Top tier low output moving coils are quite pricey these days. Some of the lower priced offerings by the same manufacturer can give you some portion of that sound, perhaps without the degree of resolution, or dynamics or some other aspect, at a much less painful price of entry.
Sonic character- seems to be all over the map, from cartridges that tend to emphasize the leading edge and can be explosive in dynamics, to others which sound warmer. I don’t want something that is overtly colored but at the same time, do not want hyper-analytical, particularly at the expense of harmonics and midrange depth.
So, pick your flavor, or sonic preference, indicate whether you can or are willing to accommodate a lower output cartridge and provide a rough idea of budget. I think you may get more targeted responses.
One other factor you might take into account- the cost of retipping by the manufacturer--
there’s a lot out there which suggests that stylus wear is greater and happens more quickly than claimed and other advice which suggests that it can be exaggerated. The difficulty is that short of having someone with knowledge and equipment look at the thing, you won’t know until it is already past the point of no return.
I’m sure I’ve grossly oversimplified everything and can be taken to task. I hope others who chime in can help you narrow down the field. It’s vast, and it’s hard to evaluate as a consumer, even if you get a chance to hear a given cartridge in a system being demonstrated.
It’s also quite fun. I’ve had great experiences with Van den Hul, Lyra, Airtight and now Koetsu. There are many others, current production, that are held in high regard and I’m sure you’ll hear about them.
@tkr- I have always wanted to use a Decca (now London Decca). Just never had the guts to do it. Now, I just might given that I’ll have a stable of other cartridges I can also rely on. Haven’t heard one in years. A classic.

I will be using the phono stage from a McIntosh c1000; Budget is probably up to $5000. Thanks for input. Mark
Take a good look at the Lyra Kleos or Kleos SL cartridges.  I just bought the standard version and really love it.  Great reviews all around on this cartridge so read them and determine if it's the right direction for you.  I previously owned a Lyra Delos and a Kiseki Purple Heart, both of which are excellent cartridges, but the Kleos is as good as I've ever heard.  Mine is mounted to a SME IV tonearm so a Kleos should play nicely with your V tonearm.  
I am a recent fan of SoundSmith carts.  The sussuro is a great match for your tonearm
+1 on getting a cart that is known to be happy in a medium mass arm. The V , no matter how good it is, is not the right arm for carts that need higher mass. I sell a line of mc carts that are quite heavy/low compliance and have seen this firsthand. A cart that is gorgeous on the right arm turns into a whiny complainer on the wrong one.
