DAC vs Tube CDplayer

My modded Cayin cd17 Mark 1  the guts of the unit,look far superior build/parts vs any DAC I've seen up to $6K+. When I finsihed modding  my Shanling CD3000, both the Cayin and the Shanling will out shoot any DAC on the market.
I am old timer and stay what is proven. I never fell for this DAC thing. 
$6K for something that weighs less than 5 lbs witha  few tiny chips, = no thanks
