Well, the case of the audible differences between the 1800 and my 5000 are pretty much clear as day if you take the time to listen. I will admit that the difference wasn't as large on movie soundtracks, but it was much easier to hear on 2-channel CDs.
Both the 1800 and 5000 were fed via identical 3' Blue Jeans cable HDMI runs directly to the Marantz SR6003. Both players were set up for bitstream output (each player only has 1 way to do this, so there is no way to "experiment" with the audio settings). The SR6003 used the same audio options for each player (the Audyssey "Preset" mode that I created). There was a slight difference in output levels between the two players according to my Rat Shack analog SPL meter, so I made sure that I evened things out via the volume control on the receiver. I've also done this same A/B test via optical coaxial feeds between the 5000 and my Pioneer Elite DV-47Ai player. The 5000 has the same harsh/bright qualities on 2-channel playback via optical coaxial as well, with the Pioneer (via the same Kimber D-60 optical coaxial cable) sounding much more rich/full than the 5000.
Towards the end of my reviewing session, I swapped out the SR6003 for an Integra DHC-9.9/Wyred 4 Sound multichannel amp setup and was able to hear the same differences (it was actually easier to hear due to the much higher performance of the amp/pre-amp combo, not that the SR6003 is a slouch). This combo is Audyssey Pro corrected (highly recommend it if you've got the capability) and I can share with you all the response graphs if you really care to see them.
Instead of just saying you don't believe something, I urge you to perform some A/B comparisons yourself (it's a big part of the fun in this hobby). You may be surprised in what you hear. Also, keep in mind that hearing is quite different between individuals, and many people do not have the ablility to perceive these differences. That doesn't mean that they don't exist.
In the case of the Samsung's sound, remember, there are a lot of electronic components that the signal passes through before it hits the HDMI/digital cable that feeds your receiver/pre-pro. Who knows what is going on at each of those junctions.
Nice of you to respond here.
I trust your expert judgement on your final analysis of the sound differences between the Denon DVD-1800BD Blu-Ray player and the Samsung BD-UP5000 Combo player.
I also believe, like you on sound differences from the Digital HDMI, Coaxial and Optical outputs from different players.
It is even more obvious, just like you said, when listening to two channels audio from CDs.
Tyler, did you also listen without Audyssey engaged?
Also, tell me if I am wrong, but my guess is that the Samsung player volume level was higher than the Denon.
Also, Tyler, can you tell me how you did the Audyssey PRO Room correction on your Integra DHC-9.9 Surround Processor? By hiring an Audyssey PRO certified person, or by yourself with the proper Audyssey PRO tool kit?
Tyler, if you can provide us with some graphs, I will greatly appreciate that from you.
Thank you so much, for an honest perpective and a truly thorough analysis of your findings.
