Here is my experience.
Took 40 minutes to setup the SR7005 and most of that was removing the inserts from banana sockets and connecting bi-amped speaker cables plus all the rest of the 5.1 speakers.
Plugged the HDMI for TV, WD TV Live and Cambridge Audio multi-format player BD, SACD, DVD Audio etc. Connected the internet cable. Turned it on and waited 11 minutes for the firmware upgrade.
Then I spent three hours enjoying the sound and making minor adjustments.
DLNA streaming is not too bad. I do not mind the simple interface. I tried controlling the music streaming with my iPod touch and it was super simple. So much better than having to keep a TV on to know what is playing.
There was some jerky playback when jumping tracks. I think buffering of the stream might need to be improved.
Compared the sound with the WD TV Live and found a small but important increase in dynamic range and stereo image.
Playing SACD and DVD Audio was almost scary. Parts of the room were rattling during Breathe from Dark Side of the Moon. I could hear every bit of hiss from master tapes on FLAC files of some old CDs. Definitely makes me want to get remastered ones.
This replaced a SR6004 and I thought it was good. The difference is quite simply huge. The 7005 was running cooler than the 6004 and outputting more power at the same time.
I mainly listen to music so have not tested movies apart for a 10 minute flip through 2001. Streaming of DVD worked well.
I look forward to a few improvements. Gapless playback via DLNA is a must for listening to music. I fail to understand why Marantz missed this. Album art would be a good thing to show.
Overall the musical clarity is stunning. I like the relative simplicity of the unit and listen to most of my music in source direct. I think some of the perceived distortion in the high end (reported previously) could be from excess processing with surround modes. In Source Direct the sound quality is noticeably cleaner and the highs are clear. Sibilant vocals can sound harsh when reproduced accurately. What really tells you that there is distortion is when you get "pure" vocal notes that sound edgy and ragged. I heard none of that. This amplifier could easily damage a lot of speakers, from what I observed when running it at the top end of its output.
I am very happy
