My set up currently chugs away reasonably well with a pair of Q Acoustics Concept 20 speakers. For info, the power plant is provided by way of a Rotel RA-1572 integrated amp (including DAC) which is likely to stay put for a while. The Concept 20s have done a perfectly reasonable job but I just have "the urge" to move up a little. Having done a bit of homework, but not yet demoed, the following three floorstanders have stubbornly stayed on the list of possibles: B & W 704 S2 Floorstanding Speaker | Bowers & Wilkins [circa GBP £1,999.00] DALI OPTICON 5 – Experiences every detail in music [circa GBP £999.00] DALI OPTICON 6 – Precise and powerful [circa GBP £1,199.00] Obviously, there are myriad other speakers out there but I wondered if anyone had first hand experience of any or all of the three listed and, if so, what was impressive or not impressive about how the speakers conveyed the music? I have heard the Rubicon 6s and really liked the overall sound - big sound stage, more than ample detail, great depth. But, the Rubicons need a significantly larger physical space than those listed and it just won't be possible to reconfigure the space I have to accommodate them. For info, rock music makes up the majority of listening (melodic (e.g. Floyd) to heavy, even the odd piece of metal (e.g. Metallica / Evanescence)) but pop-rock and classical also need to be catered for.
