Converting FLAC to which format ?

Hello all,

I have a bunch of 24/96 FLAC files that I'd like to play from a Pioneer LX-91

Of course the LX-91 being old and so on does not play DVD-Audio

So I think I should have to convert the FLAC files to DTS-HD since DTS is lossy and that would be stupid but I don't know how to do it.

Can you guys help me with the best possible solution ? Perhaps there is a better way than convert it to DTS-HD ?

Thanks a lot
