Proac response D2 or Harbeth for a Leben cs-600

Hi,
Groenlykke, I would ignore Roxy54`s poor analogy . His response in a audiophile cliche that places over emphasis on the speaker`s role in an audio system. Sure you can build a system around a speaker, but you can do the same just as sucessfully with an amplifier as the staring point. If one decided to own a SET or an OTL amp one would then audtion or seek out speakers compatible with the amp requirements. I did this when I went down the SET pathway and selected components that complemented my 300b monoblocks. This included finding benign load and higher efficiency speakers (not a difficult task at all). You have found your amp and now searching for a matching speaker. Again either method can work ouy just fine.
Good Luck

we still don't know what the current speakers are.

Charles1dad,
If it's a "cliche", maybe it is because many people feel that way. There are many ways of approaching anything, but it still seems to make more sense to choose the speaker you like best, and then the amp that brings out the best in that speaker.

Concur with Charles1dad.

To the OP, if you prefer your sound on the heavier, bassier side of things then Harbeth's are less likely to deliver.
