Dear Mtkh1567: It is no doubt that the Monaco is a today top TT like the Walker or many other out there ( including those " old " Japanese designs that I think you don't have the opportunity to heard/hear/try/test yet. )
What are the targets on a TT design?. well IMHO it has to be a design first where the TT can spin with accuracy and stabiity ( short and long run/time ) at 33.33, 45 and 78 rpm, second: it has to spin with out any internal or external distortion ( vibration, resonances, fast disipation, sound/bass feedback, platter resonances, etc, etc ) that means absolutely internal/external isolation, third: choose a material platter/mat that is/will be inert or that kill LP/platter-mat resonances, fourth: same that second target in reference to the arm board and fifth: precise/well made/high quality design execution.
All these targets are more easy to say that to achieve. Different TT designers have different approach to achieve those TT design targets ( and other ones ) and all of them share at least one TT subject: no one is free of " colorations ", there is no perfection here at least not yet and the Monaco is no exeption as good as certainly is.
IMHO and at this top level of quality TT performance and other than TT isolation the tonearm/cartridge " figure " is what could make the difference.
Regards and enjoy the music.
