Dts is lossy, compressed. When it is decoded to .wav, it is still lossy but now decompressed. Therefore much larger. Flac is lossless compression, so it will produce a file that is as much as 50% smaller than the .wav but still much larger than the .dts. Because no data are discarded.

I recently converted some dts.wav files to dts.flac and the file size increased threefold too. This is because .dts is a compressed and lossy format, flac isn't lossy (thanks Ben). I believe some folks prefer the ability to Tag flac files for their library over the bigger file size--Sent from my iWatch Air with Apple TVThat doesn't sound right (no pun intended)! Compressing a DTS-WAV file with FLAC usually results in a few percent size reduction, so something is wrong with a 3x expansion! My guess is that AudioMuxer is not losslessly compressing using FLAC, but in fact *converting* the source file to some other format, e.g. multi-channel FLAC.--
My recommendation would be to download/install the official FLAC utility (https://xiph.org/flac/download.html, downloading both FLAC for Windows [command-line tools only] and FLAC Frontend, [GUI for the official FLAC tools]), and compress your source file to FLAC using the GUI. Be sure to first de-select Replaygain, since ReplayGain would destroy the DTS encoding during playback on any decent player (that honours ReplayGain).
I don't know if your budget stretches to a new surround receiver or pre-processor, or whether you might be looking at older second-hand surround receivers. If the latter, JVC has the best DTS-handling of the major brands I've tested (which includes Sony, Pioneer and Onkyo, none of which correctly switch between DTS and stereo when fed with a non-break bit-stream of mixed-mode music, i.e. a shuffled playlist containing both stereo and DTS tracks without any break between their bit-streams).
