Which is a better speakers choice?


Hi everyone, i need help on to decide for my setup. My current rig are ProAc tablette anniversary driven by a Rega Brio R and the cables are full DH Labs. Which is the better way to go? Sell the proac and get harbeth p3esr to be matched with the rega brio r OR sell the brio r and buy a leben cs300x to be paired with the proac? I asking this coz the dealer of the harbeth and leben is far away from my place need to take a plane to get there so its very impossible for me to have a home audition.. Thanks for the help..

Milpai thanks for the reply. Yes i have a couple of friends in my area i will try to use a much powerful amps for the proacs.. I heard the tablette being driven by a 50w class a amp and yes it really gave a nice quantity of sound better in every area of the spectrum.. I heard that proacs are voiced with tube amps so i might want to try that, though i already tried an audio research vsi55 with my speakers still it didnt impress me at all it was good but it sounded too boomy! How about air tight 24w 6L6 tube amp? Or a jadis orchestra reference 40w kt88?
Hi guys thanks for the help i ended up with a leben cs300xs drives well my poacs and it sounded very nice..
