Dedicated CD Transport with Cd reading mechanism like Philips CDPRO2,used with External DAC will certainly make difference,even,when compared with moderately high end CD Players----This is the conclusion,I have arrived,after using OPPO BDP-95 and Marantz CD Players along with my existing set-up
consisting of
ACCUPHASE E450 Integrated Amplifier
Tannoy Revoltion DC6T SE Speakers
Chord Crimson RCA Interconnet Cables & Audo Quest Type-4
Speaker Cables
DAC used with AP Thyaga Transport is AMR DP 777

CD Transports essentially take the transport section of a CD player and place it into one box, removing the DAC. Why? The act of separating the CD transport from the DAC, like a separate power amplifier and pre amplifier, is designed to offer better performance than a single box unit by virtue of being designed for a single purpose, not sharing components and having separate power supplies, etc.
High end CD Transports seek to avoid jitter wherever or however possible, through various technologies and isolation techniques. These units are designed to read the CD as accurately as possible without any possibility of interference of other circuitry such as a DAC, and high end models go to great lengths to isolate the transport from the power supply, through anti-resonance measures and damping techniques which prevent vibrations from the power supply affecting the ability of the transports laser reading the disc. Many high end models will seek to avoid the mechanised loading trays of some one box CD players. As these mechanisms require power to eject and insert discs, avoiding these can prevent the need for additional circuitry and power, thus further isolating the CD reading mechanism from resonance.
