You are new to this forum, but you will soon learn that the type of language you are using wont get you very far here. You are asking about something objective, like a design, but you are using subjective terms that can mean completely different things to different people. Also, your question is very generic, like when you are asking for less components. I don't know why you think less components would equal to 'rich tone' whilst more components means 'sterile clean', whatever those terms mean.
You ask about the resistor/capacitor arrangement, I am guessing you are referring to an arrangement were a cap and resistor are used to short RF frequencies to ground whilst working as an 'audio open'. This is beneficial to avoid ground loops, but stops the cable shield working as an antenna for RF frequencies.
Your question is so broad, generic and open, that is hard to give you good advice. Perhaps you could provide schematics for us to see what you actually mean (if you ask about the resistor/capacitor arrangement, provide a pic of what you are referring to). Give more information about the transformers you have and want to use, don't expect us to give you a universal template labeled 'clean but not sterile clean DI' that you can use with whatever transformers you have.
Is there a particular DI you have in mind? that would help us give you advice. Your question, as it is, is in the same line of "What is the best DI in the world?" kind of question.
Also, if you already have the transformers, that is basically the DI, the rest is just wiring and maybe passives, unless you want to make an active DI with a transformer (but that contradicts the title of the thread); again, it is difficult to guess what you want. So the sound of your DI will essentially be the sound of your transformer, if you think your transformer is 'sterile clean' that will be the sound of the DI.
To start, I suggest you take a look at the
application notes and
schematics at Jensen Transformers' website.
