Well,
I've now got a new cabinet for my HTPC to go in. I've decided that the old Pioneer Reciever and Speakers can stay with the old TV and cabinet.
Now I'm up for some new speakers

... perhaps ...
Should I:
1) Use the Mauhan Short (MS) Bookshelf speakers I have at my office (unused) with a yamaha receiver 5.1 amp?
2) Get a new receiver amp with a new set of speakers?
3) Get the new speakers and just use the yamaha amp?
before you throw advice my way - the yamaha amp doesn't have THX or DTS - which I would love to get - but not sure if I'm going to use it properly. I already have a Jamo sub - and don't really have any ideas about rear speakers yet.
I really want the speakers to sound cool - but also look cool (I think most speakers these days all sound pretty decent).
