Please advise. Want to upgrade my speakers. Maximum budget: £1,500. Floorstanders only. Room dimensions: 16ft x 16ft, with a c. 11ft-high ceiling. Carpeted floorboards. Current kit: as below, but the Arcam A70 is soon to be replaced by an A38. Must be bi-wirable - I'm a recent bi-amp convert. [] Detest bright-, forward-, metallic-sounding treble. Very mixed music collection but yardstick/priority is classical music/accoustic jazz sounding natural, warm and alive, but no 'steel-strung' cellos, viols or lutes etc, clanking harpsichords or Miles Davis's horns inducing a Nurofen habit - if you get my drift. I prefer a balanced sound with deeep bass extension available if it's in the recording, be it Bach's organ works, Massive Attack, Burning Spear or Jacques Loussier's double-bass player. Thus far, my demo shortlist is as follows: Proac Studio 130 and 140s; Tannoy Revolution Signature DC6T. (Have tried various MAs over the years but find their top-end treble too 'metallic' for my ears...) Any other suggestions would be much appreciated. Thanks []
