The Tylers can be demoed two ways actually... One is through the 21 day home trial (but you have to essentially buy the speakers in order to do it that way, with return privilages... but you have to pay the return shipping costs)... The other is through the Home Audition program. The later is where current owners have volunteered to let you listen to their Tyler speakers in their home. There is a link to the list of owners and their email addresses (and areas of the country where they reside) on the Tyler Acoustics home page at http://www.tyleracoustics.com .
Also, for what it is worth, I like VS speakers a whole lot too... The DB99s mk II impressed me quite a bit at THE Show in Vegas this year... New they go for 10K, but for 5-6K you can get them used... I would rate them as equals with the Tyler Linbrook Signature System I recommended... The only major differences are the DB99s are *very* sensitive (so they are a superb match for SET amps), looks (I don't much care for the DB99s throwback look myself but others love it), and of course the VS cost double the price... :-) Still, even at 10K I think they are a very nice value... I just feel the Tylers are even more so... Your experience may vary... They both are superb performers in their class...
The VS VR-2s and VR-4 Jr.'s, while nice speakers to be sure, are not even close to being in the same league as the two mentioned above, IMO.
