Plinius 8200 MkII -- best integrated ss amp?

I currently have a Plinius 8200MkII but lately, i have been considering an upgrade. However, whenever i read its reviews (in TAS) and the comments of other people, it seems that this is one of the best INTEGRATED amps for the money. I fear that once i purchase a more expensive amp I might just realize that the improvement (in there is any) is not worth it.

The reason for the desire to upgrade is that, last December, i bought a demo pair of JM Lab mini-utopia and a pre-owned Musical Fidelity Nu Vista 3D CD player. Thus, i now feel that i should upgrade my amp to the same level as the cd player and the speakers (in terms of price ratio that is). (Cables are analysis plus 9 and DH labs air matrix interconnects)

Some of the people in this site advised me to get a yba passion and i think it is really a good choice. But i want to know the comments of other people who have had a direct comparison of the 8200MKII with other more expensive integrated amps.

There might be some people who upgraded to another amp from their Plinus 8200 MkII OR their might be some who downgraded to it (in terms of price not sound) since they may believe that it comes close to the sound of the more expensive integrateds in the market. I want to know their views and comments on the matter.

I want to stick with integrateds so to those who have experienced the Plinius 8200Mk II sound, how does it compare with the following integrateds:

Mark Levinson 383
Jeff Rowland Concerta II
Yba Passion
Pathos Logos
Musical Fidelity TriVista (or Nuvista)
Krell KAV 300iL/500iL
Electrocompaniet ECI 4
Audio Analogue Maestro

I know that careful matching is a must. But unfortunately dealers here in the Philippines are not keen on allowing home demos so doing a home demo with my speakers is highly improbable. Thus, comments on this matter will be extremely appreciated.

Also, if any of you hava had a succesful match of an amp with the mini-utopias please feel free to reply to this thread.

Thanks.
