If you like the sound of digital amps, there is no alternative, its the best.
If you like the Sound of analog amps, you won't like it as it doesn't sound like that.
Digital Amps are closer to the actual sound and how it is supposed to sound, in addition Sony uses its self developed capacitors solely tuned for sound. But that is not an simple answer.
60fps and high end lenses are closer to real life, and still cinema movies mostly use 24fps and smoother/unsharp lenses to create that specific cinematic look.
So if you want to get as close to the original recording as absolutely possible, there is no way around an full digital amp. If you will like that sound is something that only you can answer.
Thanks my question doesn't just relate to sonically to the competition but also functions and features.
