Thanks tecknik this is about the same time as I have heard for the ESL 15As. Little confused by stating "turn off to let caps expand", seams to me turning off they would contract. Unless you meant to let them cycle, meaning expand and contract several times. As for the Accuphase fallowing this is the primary reason for my selection. I had the chance to make an all in one purchase thanks to the unexpected guests that came calling well I was away a year back. I will miss my Ref. Marantz and CLX's, but sure to be happier in months to come.
As all was special order did not have chance to pre hear. Had trouble to get Distributer to bring in Acc. cables as not available hear, as all had to come from Japan direct so they made exception. In fact my retailer became Acc. dealer to get me what I wanted. Have you had the cables in your Acc. system, or what are you using.
I went with Audioquest Redwoods for speakers. I just figured all in one house was a good starting point. This plus some German reviews with same cables. Only thing I did not go with the Acc. PS-1220, but got the RM-75Bal at RM-45Bal price, had to wire for #6 AWG. Major over kill (this unit belongs in triple Cima-Plex theater) but sure not to be lacking on the current side of things, lots of balls.
As for swing I was more or less referring to not using compensator as one would at lower volumes. Giving a broader full range swing in bottom end. But I guess this has more to do with the human ear as a pose to signal. As such will still add some compensation for a while to help loosen up the woofers sooner. At this time still on the fence as to if I will prefer the bottom end over my previous CLX, Descent I set-up. At any rate thanks again for your writings.
