the good thing is that this guy has a phono pre for when the Vic goes away.

This Bryston BP-6 should be a considerable improvement over your Marantz (I used to own one) — more open/expanded 3D soundstage, and you’ll likely hear tons of detail from your KEFs that was previously being masked.  It’s like straight wire with gain and is completely silent and transparent, so if you’re looking for a preamp to add warmth this will not do that.  It’s got plenty of inputs and dual preamp outs to handle your sub.  No phono preamp, but most phono preamps in integrated amps aren’t very good so if/when the time comes you’re likely better off buying a separate phono pre anyway as it’s a pretty important component.  Best of luck

If budget ender  $1500. The Schiit Freya preamp with 6 sn7  tubes.$1199

I don't think Adcom preamps sound very good. I had a GTP-400 and it was meh.
