Attention Vandersteen 5A owners/ amp matches

What are all you other 5/5A owners using to drive your speakers these days. I have noticed members using Bel and also Quicksilver. I am really thinking about selling my humble farm and spending up to 15 k (new) or used on an amp. I generally have leaned in the direction of tubes in the past, but am not totally close minded to all SS right now. I prefer a slightly warmer sound, but now of course want (almost) everything with my upgrade. I am now considering Audio research , VTL S400, Jadis Ja 80, and am interested in a used pair of Jeff Rowland 9 monos. I am looking for plenty of power( although I know 5A s are o.k. with less) which I hope will translate to a relaxed effortlessness. I want the 5A to fill my 23/12/8 size room with a nice wide ,deep soundstage with good dimensionality. Thank in advance to any and all suggestions. Boy, am I going to miss that farm.
