To simplify or go old school... Looking at the new Benchmark Dac 3

My current dilemma is as follow. I have a love my Audio Research equipment (VT100 amp and LS8 pre amp) but due to the cost of re-tubing the amp I recently purchased a PS Audio stereo Stellar amp. I still have the VT100 and one day I do hope to re-tube it. I've put in some new tubes in my Audio Research LS8 pre-amp. Currently I am using a PS Audio Nu Wave DSD dac for my computer using J River with my Flac collection. I also have a Cambridge CXC CD transport that also plugs into my PS Audio dac. The pre-amp is the LS8 and my amp is now the PS Audio Stellar stereo amp. My speaker are Martin Logan Prodigy.

The question is,do I simplify and just by a Benchmark DAC 3 and run it into my PS Audio Stellar and just get rid of all my tube equipment? 

Thanks
