Initial impressions:
First, I discovered what edorr did on my own, as I did some speaker level matching and used the +10 db sub setting, also the sub + main setting. As I run four Aerial 9s, one Aerial CC5 and three Aerial SW12 subs (the three subs are chained). And Theta CB3 and Six Shooter. Set sub crossover at 40 Hz, just sound best this way in my system when I use CB3 direct with Xtreme DACs for music (oh - I use PS Audio PerfectWave Transport and DAC for stereo anyway)
My impression is that when you set in the menu for source direct to either 50 Hz or 100 Hz, that the setting is only meaningful when you also use the remote button to employ source direct to on or as you've set one of the custom modes. With the menu source direct set to off, its clear SACD is converted to PCM using the bass crossover. For SACD source direct is the only way.
Also played some DVD-A, though didn't try yet source direct vs it off.
I am just takin' my time, do a bit of listenin' here and there, some watchin' here and there, and will let my opinions form over time.
I think that barely warmed out of the box the Marantz on multi-channel SACD and DVD-A is close to my fully burned in Theta Comli (woops, it is currently selling on Ebay). So as it burns in it will surely be outstanding.
Funny thing on source direct for video. Blu Ray is native encoded at 4:2:2
YCrCb. I have a Lumagen Radiance XE and Sim2 C3X 1080. The Radiance menu shows that incoming source direct video from the 9004 though is 4:4:4. So the Marantz is doing a bit of upsampling of 4:2:2 to 4:4:4.
But the Radiance does its processing at 4:2:2. Its better to have the native HD signal go to the Radiance untouched, then let the Radiance do the processing. I have seen this with the Oppo BDP-83 blu ray player, where in the menu I can set to 4:2:2 or 4:4:4 and native 4:2:2 looks better and sharper. And early on I am disapointed because I am seeing a bit of reduction in picture quality due to the 4:4:4. I went on the Marantz website and inquired regard this two weeks ago, they said they referred it to engineering, but no response yet.
Roy Orbison - Black and White Nite - sounds fantastic on Blu Ray. Never heard it this good. Though I also have the multi-channel SACD and I will get to try that too.
Firmware update is weird. First time took forever, had to unplug unit as it wouldn't upgrade and wouldn't turn off. Later before I went to bed, I did the firmware upgrade again, and when I woke up in the AM, it had updated fine.
Today, I decided to do the firmware update that info was posted on the Marantz website yesterday. This time download went quick, maybe fifteen minutes, but then the player hung up endlessly with front panel saying "Waiting". Went to dinner, came back few hours later, player still said "waiting". I gave up. Couldn't turn off unit from front. Unplugged power cord, then plugged back in. Before I could turn unit on from front, it showed on the front panel that it was updating. And in a few minutes it completed updating. And when I went back into firmware upgrade, it indicated that I had latest firmware.
Marantz should have the menu or front panel display the firmware version and date of the current loaded firmeare.
What are your experiences on firmware update?
