MF Tri Vista or Nu Vista Amp or Pathos Logos


I wonder if MF Tri Vista better choice than Nu Vista providing that both amps will easaly drive my present speakers.
Heard that some of the NuVista's produce a hum in the speakers and Tri Vista is more reliable.
On the other hand some people say older MF models are better than newer.Can't compare both side by side so
any thoughts would be appreciated.
Also consider Pathos Logos.
Can this one compete with Nu/Tri Vistas.

Thanks

The Nu-vista sounds more smooth and involving than the tri-vista.But the Tri-vista has more control and drive in the low freq. The sound is more analytical than the Nu-vista is. In some situations It can ben a little harsh. I did a lot of demo's for the distributer of Musical Fidelity, so I know them both very well. Why where you disapointed in the kw500?
