would the Sony SCD 5400 Ex make a good transport?

I recently acquired a Sony SCD 5400 hoping it would be an upgrade from my Rega Apollo. While there is much to admire in terms of resolution and PRAT I find the sound has a lot of the digital glare/hardness; strings are quite steely which is tiring. Was wondering if this could be corrected with a (better?)DAC using the Sony as a transport. Or is it better to look for another player. The Sony costs as much as I want to pay for a CD player
