As I noted earlier, I managed to read Marty's feedback before going to Venetian this morning so I mad the KEF and Wilson/LAM my first stops.
When I arrived at KEF, I had a double-take. Why? 'cause these are on-wall speakers. Here is the picture:
That said, they were pretty clever in what they were playing. It was dynamic, techno music in surround. The video was as bad as it could get but the sound was well done. It had a ton of snap. Alas, as is typical of these tiny back boxes (we are talking about a 1-2 inch box behind tiny drivers), there is no true bass. The little sub brings the thumping and there is emptiness until you hit the mids and highs. So the sound is bright which can result in one thinking there is a lot of resolution and clarity. But laws of physics don't bend like the movie Matrix
. Little drivers in little boxes tend to not have much response below 100-110 Hz and little subs don't fill the rest of the gap. Fun stuff to be sure. But let's not compare them to any system of sufficient size.
I then went to the Wilson/LAMM room in question. It was full room with many people there standing beyond the seating available. I grabbed an empty chair (the blue one) here:
And wouldn't you know it, the sound was lifeless as Marty mentioned. They were playing Opera music and the thing had no highs and no lows. It was also rather quiet. Yes, I detected some of the lushness I have heard in Steve's midrange performance. But it was quite faint with the rest of the experience not being too good at all.
All this time, there were a couple of guys occupying the love seat. You know the type. Sitting there looking serious and absolutely stiff as if deep in thought or appreciation. Kind of like seeing a guy at modern art museum starring at a blank canvas with you not knowing if he is pretending to understand it or not
.
Anyway, just when I was going to give up on the whole thing, the two guys stood up. I quick ran over and sat in their spot. Oh wow. The transformation was quite massive. The highs came back. The resolution came back. And midrange became considerably more luscious. Best way I can explain the difference is if you took headphones and pulled their cups out 1 inch. That is how it sounded in the old seat.
Explanation of the effect seems pretty straightforward in my book:
1. The speakers are toed in hugely. This clearly makes for a narrow sweet spot. Where I was sitting before, was completely out of that zone. If I were them, I would not put all of those chairs there, pretending one can have a good experience there. Bookshelf speakers sound better than sitting so far off axis from the crosspoint of the two speakers.
2. There was zero room treatment. I don't care how expensive the speakers and the amps are. You need room treatment for good sound. Almost every good sound I heard was with treated rooms. Sitting in the sweet spot did allow one to hear less of the room but not in other spots.
3. No sub, not enough guts. Let's get real. You need a sledgehammer to move those giant drivers in the Wilsons. The LAMMs just don't have the power it takes to move them. As a result, there was zero bass presence. And dynamics suffered too. In one segment, the levels went up quite a bit but the sound also got brighter. That tells me the amps were distorting. Steve has subs to carry the weight and let the LAMMs do their thing above that. Not so here.
All in all, the experience in an absolute scale went from C- to B+. Clearly not the best at the show but also nowhere even remotely where the KEFs were.
OK, it is 2:30am and I need to get some sleep. Hopefully this stuff is coherent enough
