All vandersteen users ?

have been using vk55: 55wpc for a pair of vandersteen 2ce Sig2 where have been recently told by another dealer that unless we hit 200W, one cannot really imagine what these speakers are capable of ..... he mentioned immensely higher 'headroom'

now looking at either upgrading to

1. a pair of vk55 monblocks
2. or just a vk75

Speakers wise, wld be looking at going up to vandersteen quatro...

Qn: Wld 02 x vk55 monoblocks really be too little for vandersteen 2ce Sig2 OR for that matter the quatro..

any advice from any vandersteen users wld be highly appreciated...
