The 5003, 1603 and 1604 all use the same version of Audyssey MultEQ so they should sound fairly similar. Although 4k is likely still 5 years off from being main stream, the 1604 adds Zone 2 pre-outs should you want to run a 7.1 setup in the main zone and also features "All Zone Stereo" in which you would be able to pass the same HDMI source playing in the main zone to Zone 2 as well whereas on the 1603 you would have to also connect an analog cable from the HDMI source in order to pass the audio to Zone 2. If you don't require these Zone 2 features, then the 1603 should serve you just as well. Audyssey MultEQ XT would be a slight step up in audio quality; however is only featured on the SR models.
Quoting jdsmoothie here because it wouldn't just let me reply to the thread, but his information is relevant as I'm wondering if the 1604 would be a good match to setup. Based on jdsmoothies' excellent reply and my limited understanding of specs I think it is but would appreciate if someone could confirm. I know its an owners thread but after reading through it, it seems a lot of people were asking about how this avr would pair with their speakers so I hope its okay to do the same.
My setup currently is:
- KEF 3005 (the older series, without the wireless rears, mine are hard wired) 5.1 surround with two additional satellites from the same series making it 7.1
- Buttkicker LFE powered off it's own Buttkicker amp (connected to the avr using a Y cable so that the one sub out is connected to the KEF sub and buttkicker)
- old but trustworthly Panasonic SA-XR700 (don't laugh, I know its old but it does sound very good)
The room is a dedicated theatre (front projection), and and such we watch movies almost 100% of the time. Once in a while a bit of gaming. I only have two inputs, one an HTPC running Linux and XBMC and one an infrequently used XBox 360. My main purpose for this AVR is to bitstream the HD audio tracks from Blurays as the old Panny does not support DTS-MA or Dolby TrueHD, I also like the app based control as my current receiver is hidden in a closet along with the other gear. I won't use any of the other sources like Airplay or the networked audio sources.
My other concern is my old amp is 100watts per channel while this one is 50watts per channel. Wondering if I'll be disappointed with the performance of this amp as a replacement?
If anyone can provide some advice I would really appreciate it. Thank you.
