Out of the ones you selected to my ears only the Anthem was a better sounding processor. The Marantz will provide you with a lot more features.
I am a Quested Speaker Dealer for South East Asia and have been through tons of processors including Datasat and Trinnov. After spending a lot of time with high end processors and mid level processors I have chosen the Anthem for my personal rooms.
I don't use room correction anymore, I work on the room and then the Processor EQ only. I find this method gives me better natural non fatiguing sound.
Clients can wish to buy what ever they can afford.
The Trinnov was a terrible sounding processor which has a ton of features often reshapring the sound to what ever suites you at the expense of more distortion adding into the chain. Mind you this is not actual distortion you would pin point out easily but Trinnov was the least natural sound processor even with all the Room correction turned off. Honestly I can never recommend this processor to anyone unless you absolutely need over 16 channels and you live in mansion.
Next up is the Datasat, All Room correction turned off, it still have a nice natural sound to it, their was a smoothness to the sound but tons of bass at the same time Datasat just overall sounding better than Trinnov room correction turned on or off.
Marantz Not bad, room correction sucks but you can bypass this and get outboard DSP Dirac boxes to do the room correction for you.
Anthem, similar sound to Datasat with extra features but probably not as flexible as Datasat when you need more pro level tools to work on getting things done right. Out of all the processor the AVM 60 when correctly setup with speaker and amplification gave me enough satisfaction as the Datasat in overall steering of the sound around the room and the bass to clarity.
Why spend 20,000 on a digital gear when you can match performance with 2500 dollars easily.
