Marantz PM10 class D amp

yes, I am willing to spend anywhere around $8,000-$9,000 for an integrated amp if it is good enough.

I currently have a separate system consisted of ARC preamp + Mark Levinson 27.5. These sound great except that they have to go cause I am moving to a smaller apartment, and we simply don't have space for them anymore. Plus, my wife does not want to see some bulky amp + preamp sitting on top of our tv stand :(

Base on your suggestion though, I will cross the Lyngdorf off my list.

One more amp I am also looking at is the Mcintosh MA5300 Integrated Amplifier. I wonder how it is going to sound, comparing to other int. solution. 

I wouldn’t be too quick to eliminate options just based on on-paper specs. If that were the case, no one would be buying any tube components. That aside, I’ve only heard two of the components on your list, Marantz PM10 and the ML383 - as well as ML585, but not with KEFs. The PM10 was paired with the Golden Ear Reference and I found the sound hyper-detailed for my taste. Great for the first 10-15 minutes but I felt it lacked musicality. The ML383 was paired with several different speakers including Revel Studio, Harbeth 30.1, and a Paradigm - not sure about the model. It sounded dynamic, musical, and extremely fluid almost regardless of the speakers. The ML585 sounded very similar to the ML383 but it seemed to have a slightly better bass response. If you like the Levinson sound, you’ll not be disappointed with either the ML383 or ML585. You can pick up a used ML585 within your budget.
Good luck.

P.S. I would add T+A elektroakustik HV Series integrated to the list. They seem to get great reviews.

Marantz PM 10 has Ncore module from Hypex for power section but not sure how good is its pre department. If you are not tight on your budget, get a Pass Labs INT 150.

How can you make statements in regards to amplifier performance/musicality when you are not using the same speakers to compare them (and maybe not even in the same room)? 

@viethluu

What I was getting at is that the rule of thumb is that the speakers (including subs if you have) should make up no less than 1/2 your total system price. You are not anywhere close to meeting this. If you bought some/all used, then that throws it off, but you should get where I’m coming from. The difference between a $10000 speaker vs a $1000 speaker are much more apparent than a $10000 integrated amp vs a $1000 integrated amp.
