Wilson MAXX musicallity and sound

Please post a picture of your room, also post measurements and placements of room treatments.

I am missing the liquid and icy sound of high end audio with the following expensive combination . How can I improve achieve that dream sound?

Of course you are. This system is pretty much SOTA. It won't give you warm sloppy bass or icy sound. In short not boom boom tizz. The midrange will be quite forward compared to other speakers (not because it is - but because it is flat where most normally dip).

However, your amplification looks woefully underpowered for the speakers - they dip to nearly 2 Ohm - an extremely difficult load - so you may need something with high current capability like a Krell.

If the sound is claustrophobic (lacks air or spaciousness = is that what you mean by "liquid") then it may be a grill or a placement issue. The chunky way this speaker is built will inevitably mean that you get odd grill effects and some additional edge diffraction compared to other speakers - depending on your listening position/placement this may be more or less intrusive. (For example, the support structure for the midrange tweeter module may have an influence and you might try some foam padding there to see if it might be affecting the sound. Also check the manual to see if thois uis supposed to be used with grill on or grill off....I suspect the grill will make a juge difference.)

No matter how great the speaker and electronics, the speaker must be properly placed in the room. Given the weight and size, these babies are often just "plopped" into an approximately good position and left to disappoint the owner forever.

IMHO, you should beg and pay a Sumiko dealer to come out and do a Sumiko Master Set for you. Don't change any equipment until you do this. You can't judge a system until the speakers are properly set. In the few Wilson systems that I've heard, this is a chronic problem, with great speakers not reaching near their potential due to lackluster placement.

See my review of the Sumiko Master Set and Guidocorona's comments regarding the Master Set of his system for more in-depth discussion.

2 years ago I have a pair of watt puppy 6's, moved into a new house. Just wasn't happy with the sound. Called a Wilson dealer in Austin, TX. He spent about 8 !!! Hours dailing them in. It makes a major difference.

Since, I've upgraded to the WP 8's. Seriously you have great speakers. Amp matching is critical, I can't really comment on your electronics, I just am not familiar with them.

I can say, Wilson speaker positioning is critical and transformation when done perfectly.

Good luck!

In addition to speaker placement (so critical for Wilson speakers, need to get them right down to the last 1/2 inch), room treatment you can also explore vibration control.

You didn't mention how you are placing your equipment but in my experience proper vibration not only improves but is critical in any hi-end system. The changes can be night and day and seems to affect the extreme ends of the sound frequency - top and bottom end. Exactly the issues you are experiencing.
