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

re: "... However an owner said that you better have warm speakers and it might not do so well with poor recordings..."

I am an OSIRIS owner. From direct personal experience I do not agree that "warm" speakers are required. We test-drove many different pairs before settling on our final choice.

Any brand top quality gear will highlight any shortcomings in poor quality recordings. The amp simply reproduces what is fed to it... "garbage in = garbage out" as the homily goes. That points to either the quality of the source or the recording, or both.
I have a couple of suggestions, but it partly depends on power needs. I prefer tubes, but one of the best amps I have heard, regardless of topography, was the Lavardin IT, only 50 watts though.

The best SS I have heard, cost no object, was the Dartzeel 8550. Unfortunately, cost is always an object, so I will never own one.
Given your need for power (150+ watts) and your desire for solid state, I'd say you should go with the Gryphon Diablo, the Gamut, the Dartzeel, the OLD jeff rowland integrateds, or the Pass Labs.

I've heard good things about the Coda units also, but I cant vouch for them like I can the others above.

Depending on whether you need a phono stage or not, there are only 3 solid state 150+ watt players left (the Gryphon, the DartZeel, and the old Jeff Rowlands). You'll pay $5k-$15k on the used market depending on what you chase after. Beware though, the DartZeel has some ridiculous keyfob George Orwell ID system associated with it, so if you buy it used, you could be in for a headache.

If I did not need a phono stage, I would have gone with the GamuT. If I only needed less than 50 watts, I would have gone with the Pass Labs INT-30.

Everything else (including a bunch of the recommendations you've heard already in this thread) will come up short. Cheap volume controls. Lots of op-amps. Switching power supplies. And on and on. Trust me - I've done the research and paid the big bucks to learn my lesson(s).

I've owned big solid state integrateds from many manufacturers (Musical Fidelity, Marantz, Sim Audio, Burmester, etc). I dont know what your budget is, but if you really want the best (given your criteria of solid state and more than 150+ watts), refer to my suggestions at the beginning of this post.
