Proac response D2 or Harbeth for a Leben cs-600

Yes Nolitan, ATCs are a different breed. They turned out to be the best speakers among the 50 odd speakers I heard when I was at Singapore shopping for my next speakers. They speak truth with such genuine-ness and authenticity that you would even enjoy poor recordings on them as long as there is some good music in that recording. Basically you would not hate them for telling the truth. Finally, it is the God of Tone and Timbre !! You can tell the difference between a Steinway and a Yamaha in seconds, just by the tone.

Love ATC. They never work with tubes, unless you mate a tube pre-amp with their active ones.

I am yet to get into their actives. However I have managed to mate a good tube preamp with a Symphonic Line power amp driving the speakers.

But I would be amazed if a high quality high powered tube amp doesnt work with the ATC !! Though they are low in sensitivity they are not difficult loads. A nice 845 based tube amp putting out 100 watts per channel should work well I guess.

Do you think cs600 is great combi with Zu druids MKIV/08? or should I go with cs300xs
