I am a Vandersteen 2CE Sig 2 owner for the past seven years and it’s being driven by my McIntosh monoblocks MC601 (600 watts) and all I can say is wow! The 2CE Sig 2 really woke up surprisingly it can handle the power of my amp without any problem and I listen quite loud all the time. If the speakers are placed properly, it can be overwhelmingly sweet. Playing mostly audiophile recording makes it sounds like you’re listening/watching to a live music, sounds way better than some of the speakers out there that cost five time more. I highly recommend the 2CE Sig 2, it’s a lot of speakers for the money.
