The best integrated amplifier


Hi All
Right now I am using a Marantz PM-KI Pearl amp to drive Esoteric MG-20 speakers. I feel that a better amplifier would give them a bit more get up and go. I would like to stick with an integrated and have short listed:
Pass Labs INT-150
Moon 700i
Audio Research dsi150
GammuT Di 150
As a starting point for auditioning. Now to the question:
Is there anything else I should put on the list?
Any experience with the products listed would be helpful.
Thanks

Luxman should be on this list.

Teajay, have you heard the new Modwright 200? That is one nice looking integrated and whats more is something like that can really simplify ones system. Of course you can get the preamp/Amp in one box but also a USB DAC too. I know it is 200 watts, which is great, but what about current?
If you don't add Ayre to your audition list, you would be doing yourself a great disservice.
OP, are you working on the assumption that you will need at least 100 watts come what may?
