Then why do you believe what you read in those two places that one actually sounded superior to the other, how many said so and/or did some say the other sounded superior, or all said the same?
Don't get me wrong I am just curious to know how we all approach such subjective impressions of people. In my experience, if you look at a large enough sample, such as say Amazon reviews on a popular product, you bound to find all sorts of people offering all sorts of reviews. Regardless, I would definitely go with the 4800 too.
Now if we look only on the objective side of things such as reliability track records, features, and specifications, it is very possible to make some sense of what people said in different places, and may be trust the majority views more. On the subjective side (perception of how each sound to them), such as, an AVR, you will likely find a distributed % that would range from excellent, very good, good, average, to even poor so then would you still analyze the results mathematically?
From the places I read (more than 2), I remember seeing some said the 3800 sounded better than the 3700 while others said the opposite, for example, the prolific reviewer Mr. A Robinson (okay, I would only watch his video reviews for entertainment if there are nothing else to watch
), so how would you know who to trust, that will perceive the same that you would, in your own set up in your own room? Again, just curious..
By the way, also on the objective side of the equation, we have the following known facts:
- Both share the same preamp/dac signal path block diagrams as show in the Masimo video and other Denon website information.
- The power amp parts and circuitry between the 3600, 3700, 4400, 4500, 4700 are identical so it would almost a certainty (but not 100%) that it would be the same case with the 3800 vs 4800.
- The power supply of the 4800 is slightly larger.
- The layout of the two are different, mainly on the power amp section, in that the 4800 now has adopted the monolithic layout that was previous found on the top two models only.
- Both use the same Griffin lite XP DSP, same quantity too.
So on the objective side, in all likelihood, any audible difference would be subtle and in terms of noise only, not distortion, at least not significant enough to result in audible differences. Frequency response will be identical or near identical.
