Heads Up: ARC is introducing the new SP-20 in Fall

As far as I am aware , the companies in the Fine Sounds group are operating totally independently so it will be interesting to see if this turns out to be the case . As for myself , I would be tempted to rationalise my Ph5 and LS27 into an SP 20 if the sonics were comaparable .

By all accounts the companies owned by Fine Sounds do operate independently with the exception of Wadia which is now located at the ARC facility. In that regard, I know that they share some of ARCs administrative personnel. Hopefully, that's as far as it goes.
Having spoken to various members of the ARC working crew over the years, there was a consensus that Wilson speakers enabled the production team and the listening group to hear precisely what sounds their products were generating. ARC has kept Wilson 7s, then, I believe 8s and later Sashas as well as Maxx 2 and Maxx3s in their various listening areas.
Is it more than a coincidence that Sonus Faber (a perhaps more beautiful but slightly less transparent sounding speaker) is now in the house presumably in Wilson's place? Are there Wilson speakers in other rooms? Don't know.

I remember back in the Golden Era of hifi that ARC used Infinity RS1's and the Infinity IRS , myself , I used to own a pair of Infinity RS2b's . Although I have no doubt that the Wilson's are a step forward I really look back with fond memories of that monthly ritual of polishing my Infinity's with teak oil and marvelling at the quality of the woodwork , those Infinity's from the late 70's to late 80's were pieces of art , methinks .

Chris -- were the RS speakers the electrostats? If so, I remember those speakers too. They were spectacular.

@Bifwynne , no , they were not electrostats , they were planar , emits & emims ( electromagnetic induction midrange / tweeter ) & yes , they were spectacular . The Boss' Born to Run played at high volume through a pair of RS1's was a joy to behold , but not from the neighbours' perspective .....
