I have NOVA V's and I am not happy

OP, after many years of trials and errors I realized that synergy is the very important aspect of the system. Like one gentlemen above, I have now Nova V driven by Luxman 590axii and frond end is luxman d-10x. Sound is so natural, airy and 3D with greatly defined tight textured bass.

I had more expensive setups in my home but they all did not sound as good as my current setup. Room acoustics and synergy  between components and cables is the key. 
what is your front end? What are your Ics and  power cords? Outlets? Dedicated lines?

it’s all very important. 

Cables - I settled with audience front raw for speaker cables, Ics. 
Currently my power cords are very good Triode wire labs Obsessions but saving for Audience front raw. Outlets - all furutech latest gdx  ncf rhodium.

my recent discovery  - all AC outlets on the path to your components including wall and power conditioner or distributor should be from the same make/model to avoid mismatch.
Mechanical  isolation also crucially  important. 

Don’t  skimp on all these things -especially cables and outlets. Or you never hear what you gear is capable of and as result waste tons of money chasing for that sound.
 

The Nova 5s are fantastic speakers. Just a quick glance at this thread I'm thinking the ML isn't the best match.  Also I would upgrade the Kimber 8TC and look into warmer interconnects. The Luxman, McIntosh or consider Audio Research amps. I have the Olympica 3 and they are a tad warmer than the Nova series. McIntosh are great amps however,  I found a MC402 & MC452 didn't have enough low level detail. I then trusted my gut and purchased a ARC REF75SE. Perfect match for the 03. The newer McIntosh amps also seem to be a great match for the Nova series. 

I agree with Bigkidz. I’d try another amp first. Unless you listen in a terrible space, I’d think those speakers should come alive with decent cables, a great source and good amp. At $12k that amp should get them to sing.

How big is your room and what sources do you use?

I’d think a Luxman would sound great with this speakers. I’m perpetually confused by Mark Levinson. Who is the designer and soul behind them?

I nice heard a top line Rotel sound better with a pair of large B and Ws and Sonus Fabre Olympica IIIs than a five figure Levinson.

id bet a reference series Marantz would do the trick smoothly at high volumes too.

@rlross3 If you want to bring out the big guns to tackle this problem. I recommend a DSP genius, Mitch Barnett. That is if you are a ROON or JRiver user.

Accurate Sound Reproduction Using DSP , Barnett, Mitch - Amazon.com

You will have to measure your room with a decent mic ($100) and the free REW software. He will give easy instructions on how to do this. The dude is a genius on this stuff and can make your gear work. 

I used his remote services for my small room. However, after a lot of testing with treatments and moving furniture, I was able to get great sound without the DSP. Not everyone has the ability to add treatments and move furniture, so the DSP is a great safety net.

There are other ways to do this type of DSP (such as in audio hardware) but nothing as powerful as what Mitch does his very expensive DSP computer software (I forgot which 2 he uses).

I have two systems. The living room system cannot sound as good as my loft NO MATTER WHAT I do. The gear is far more expensive in the living room.  The room is your answer. I have accepted defeat in my case.
