Looking for Power amplifiers with built in A/B speaker switches

I have a budget of $15K, new or used. I have two pairs of speakers and would love to have the capability to be able to switch back and forth between them without needed to fool around with changing speaker wires all the time. I'm NOT looking for any type of external switchbox. I want this to be part of the amplifiers function. I know Accuphase has this ability in some of their amps and was looking at the P-4600. I would also like the new amp to be an improvement on what I have now (Coda #8 V1). I would like something that can manage 4 ohms loads since both my speakers are 4 ohm and a high current design of at least 200-300 watts into 4 ohms. Any suggestions?

260 wpc into 4 ohms, run it into the preamp with speaker switching,

Of course, you realize, that is simply like having a Niles speaker selector box built into your preamp

Speaker selectors were popular back in the day for a total home system.  When my track home was being built, I came in and ran monster cable to the den, garage and back yard.  I have a old Adcom GFS-4 speaker selector next to my Adcom GFA-585LE amp to select the area to play the music.  Nowadays with blue tooth, the system is absolete, but, I had many get togethers where all 6 speakers were on and loud pushing that Adcom.  The setup still works today, and the long speaker runs resistance probably save the amp.  Although, the amp has been serviced a few times because of leaky caps - common to that model.   The biggest disadvantage with a speaker selector running multiple rooms at the same time , besides halving the ohms a few times, is not being able to manage the volume in each area.  For me, the backyard and garage volume was always too low, and the den volume was always too high.

In my experience, speaker switching is a bottleneck to an amp's design. Use a 2nd power amp for the 2nd set of speakers.
