First let me say that I am a huge dynaudio fan. The x12 gems have gotten better with every upgrade I have made to my system. The combination of Metrum Octave with the Bryston amp (3bSST2) makes the Dyns sound heavenly...but the question I have is, are there other levels of heaven I can get to??? One huge limiting factor is the size of my listening room. At only 3.5m by 4.5m, I can only move the speakers 30cm from the back wall. The eliminates all the higher end Dynaudios as well as so many other speakers. I could move to the new x14 and be safe, but I'm afraid that's not much of an upgrade. Whathifi was not thrilled with them but other reviewers raved about them. I realize that WhatHiFi loves very fast and detailed speakers and the x14's might not be up the best in that regard. Would the recently reviewed (and loved) Rubicon 2 be a worthy upgrade? Is it significantly better than the x14s would be? Is 30cm from the back wall really enough for them? For twice the price of the x14, will they sound better? The other speakers that I am most interested in is the ATC SCM series. I've heard them and been very impressed, especially with acoustic music and vocals. I'd like to keep this upgrade under $6,000US if I can. Earl
