acoustic signature challenger

anyone use on of these, thinking of abandoning my sl12 and placing my origin live encounter on one of these

read very good review in HFW, and know Walrus sell it but wondered if anyone had experience of this deck,

 

I nearly bought a final tool TT, had an amazing review also. There was one secondhand but after factoring in postage from Greece it was hardly a bargain. They weigh the same as an anvil.

 

thye do look attractive dont they, thing is i am not in a position to buy yet, mentally spending at the mo so dont want to waste walrus's time until ready
i am borrowing a phono stage to properly evaluate my deck as well before i spend unnecessarily but the ac sig's look bloody fascinating with all that mass
