Any great places to hear speakers in Vegas?

I go to Vegas alot. Have taught 35 workshops to help people learn to play dice. The food and shows are superb. But indeed I do not venture off strip very much. Thanks I will check Tweeters becuase I want to hear the Krell Res 2. If anyone wants to hear B&O at their best, the Fashion Show Mall in Vegas has a great listening room.

More possibilities:

Ultimate Electronics:
Mostly TVs but carries KEF speakers. Located at Rainbow and Alta (west side).

Magnolia Audio:
Best Buys attempt at high end home theater.
Located inside Best Buy store at Rainbow and Lake Mead (north of Ultimate Electronics).

Sony Superstore:
Located in the Forum shops at Ceasars Palace.
Don't know what Sony is doing with speakers these days but may be worth a look.

Tweeters:
Charlston at Rampart
Look out for that perky concierge!
If you are here after April 17th, check out the new Red Rock Resort (owned by Station Casinos) just a few miles west of Tweeters on Charlston.
Reported to have cost $900 mil.

Thanks ElDragon and Dweller for taking time to respond. I will check these out. I am very surprised that there not any ultimate listening stores, given high rollers and hosting the CES.
