In the interim, I am curious about what speaker cables have you used with the Perspectives?
First, CONGRATS!!! on an awesome set of speakers. At this level, to me synergy with your specific tastes and system in choosing cables is paramount, and I agree with others there’s no need to overspend on cables if you just choose wisely. Along these lines I’d ask what sound qualities are you looking for or not looking for? To my ears, JA speakers are very neutral yet not at all clinical — hence a lot of their beauty along with throwing off an exceptional 3D soundstage. So, look at the Perspectives as a blank slate that you can affect to your will with the choice you make. To me, I think JA speakers are tuned damn-near perfectly so my goal would be to find something to let them do what they do and don’t hamstring or restrict them with something that diminishes any of their considerable strengths.
Toward that end I’ll mention the Acoustic Zen Double Barrel cables. I use Soliloquy 6.2 speakers that, to me, offer very similar sound characteristics to JA speakers (in fact I chose these over the RM22s and RM25s after hearing them side by side in the same system) and the AZ Double Barrel cables just play right into all their strengths beautifully. I’ll highlight excellent soundstage and 3D imaging with an incredibly natural and dynamic midrange and airy, detailed highs without ever getting harsh. Just another option to maybe explore FWIW, and enjoy your wonderful new speakers!
