I haven't heard the ACTs, but I have heard both the Arc and Discovery, admittedly in a so-so room. For me, the sound was dry and uninvolving, though it may have just been the room.

Have premiered the WPs but may not be able to audition the ACT; however, before I invest in the WPs I'd like feedback on the ACT. I have read great things about these speakers. Musicality and dynamics are important to me. I have a lot of acoustic jazz, jazz fusion, male and female vocalists, blues and house music on vinyl and cds that I will be playing. Amplification will be Spectron amps in monobloc configuration and Joules preamp. Really would like to hear from individuals who have actually heard, or own these speakers and can make comments and comparisons based upon actual experience. Thanks.
