Which System???

none of them. these are non-tube systems.

Mrtennis
What if a unit such as the Musical Fidelity x10 is inserted in to the system?Would that make it tubie enough?

All three will provide musicial enjoyment PROVIDED the remainder of the system (speakers and cables at the very least) are chosen to augument each option's attributes. Though I have yet to hear Naim directly, I do know from personal experience that the Krell and Rega systems are capable of long term musical enjoyment.

What is the goal of this thread? Is this for a personal purchasing decision or are you angling?

i owned a musical fidelity a5 cd player and have had the opportunity to audition musical fidelity-based systems at ces.

i do not hear a tube sound when i listen to musical fidelity components.

i suspect that a low powered set amp would be necessary to attian a "tube-like" sound.
many of the newer pentode or tetrode designs sound more like transistors than tubes.

Actually, I'm just curious to hear others opinions on these pairings. All are system combinations that interest me.
