Farhad, the Mephisto doesn't exactly "lack" bass - it's output does seems softer than the Audio Aero when using similar interconnects and power cords.
Changing the interconnects around produces more or less bass perceived bass on each of these units.
For instance, I found for both of these players, I liked to use Audio Note Kondo KSL between the CD and Preamp. For the Mephisto, I liked a pair of NBS Statement between the preamp and amp... This gave fantastic dynamics - superior detail and created a certain silence between notes. Strong and accurate bass.
Using the same interconnects on the Audio Aero gave me too much resolution - it was less comfortable to listen to. And seemed a bit "harsh" - Acoustic bass was bigger sounding but not quite accurate. So I swapped out the NBS Statement for a Stealth PGS. The PGS smoothed out some of the detail and added a softer quality to the music, taking some of the edge off - bass was diminished ever so slightly by seeming a bit less overpowering and so were the overall dynamics. As a result the soundstage tightened and became more focused. I felt that the PGS was a better match for the Audio Aero than the NBS was. But may not be the perfect IC for this combo. It would take more time to decide.
So far, I am totally undecided whether or not a CD player is the upgrade to make if you seek increased bass. While we all want all the frequencies I have found that most every high end CD player out there will help a system to produce its optimal level of bass only when the right associated interconnects and power cords are used.
Neglecting that will result in limited performance of your CD player - regardless of which one you choose.
As audiophiles we want it all - we want WEIGHT in our music and Transparency... We want Macrodynamics and Microdynamics... we want speed we want pace and timing, we want inner-detail and outer extension. It is very difficult to get everything - which makes this hobby such a challenge. Live music is capable of producing everything but very few high end systems are.
This is why tweaking with the right interconnects and powercords is mandatory at this level of audio-perfection. It takes time and patience but ultimately pays off in results.
Does this make sense?
