I'm getting a bit further here with the TP 2.0. As previously stated, these are
serious speakers. Of course, monitors like these, will reveil exactely what you are hooking them up with and it is very easy to hear a clear difference even from cables etc. Personally I like this, and I have been reevaluating a lot of equipment lately.
Although they sound good with "lower grade" but honest equipment, they have taken just about any challange I have been able to give them, just showing exactely the qualities (or lack of) with any front end combination.
I can say for sure, they do love power, the more the better. Yesterday I hooked them up with a set of Belles 350A monoblocks (powered through JPS Aluminatra power cords, which does quite some good) These monoblocks are conservatively rated @ 800W but are likely closer to 1kW in 8 ohm. This was awesome, incredible that all that sound came from those relatively small speakers, the bass became extremely physical, but still clean, detailed and very well controlled. They easily manage to shake the entire listening room.
I consider the TP 2.0 to be one of the biggest bargains within monitors or true high end speakers. Well, hey, don't just take my word for it (I sell these babies)

Audition yourself, it wont take long to notice these are truely special.
Best regards,
