Squeezebox Touch with no external DAC--Ideas

I am running my Squeezebox Touch with RAC cables to an older McIntosh Preamp(MX118) using a McIntosh MC206 amp. Mostly I stream loaded CDs from a computer using the latest ITunes program. The sound is very good. Question could I run the Sqeezebox digital thru my McIntosh MVP 861 CD player and do you think it would sound better. I know my preamp is dated. I listen to Thiel CS 2.3 and JL Audio sub. Thanks
