I believe you have two issues here.
The first one is the connection between HT receiver and your stereo pre-amp or integrated. What you should look after is the existence of so called: HT input or unity gain input on your pre-amp or integrated. Usually modern pre-amps and integrated amps do have such input. It is important because this input allows the volume control to be performed on your AVR - stereo pre-amp or integrated doesn't influence the volume coming from external source for this input. That will make your life a bit easier. In other case you will have to deal with two volume settings, which is also not the end of the world ...
Second issue are the Thiels. As somebody already mentioned it, they are very current hungry. $500 S/H Rotel will not drive them properly. You need a very powerful amp of high quality to make them sing. Otherwise you may be very dissappointed with Thiels. So basically you have two options here: either you go for something like Bryston 4B-SST or Pass Labs X-250.5 or similar; or you go for other speakers.
I hope this helps ...
