Are the really pricey HT Pre Amps worth it?


Looking at a pre amp upgrade.  Are the real expensive pre amps better than a Marantz AV8805?  With prices $12k plus for even used high end pre amps here, are the extra $ really worth it?
Currently have a 11.2 Atmos config.  Marantz AV8802a, 2 monoprice (ATI) amps, Oppo, Sony 4K projector, etc.

No.  When I upgraded my HT processor for 4K I went from the Marantz AV8802 to the AV7704, going down one range in the Marantz lineup.  No difference in sound quality at all.  If there's some specific feature you need or connections you don't have, maybe it's worth spending more, but I have started to look at them as almost disposable appliances.
I traded up my marantz 8802a set up as 7.2.4 recently for a Trinnov Altitude 16. I have thoroughly enjoyed it and happy with the upgrade. Is it worth it? Yes If you are willing to pay for better sq. But it’s a lot more $ so it is question of your wallet and priorities. The Marantz was very good so you should be happy if you keep it.  If you have the cash and want more of whatever you are looking for, you will be very happy with the trinnov.
