It's 16'x25' with a 14' vaulted ceiling, so now I'm thinking maybe I need something more robust. I am trying to keep things reasonable price wise, as this is our secondary H/T setup. I spent three years building a dedicated H/T in our basement, with much great help from all of the good folks in this forum over on the "Dedicated Theater" thread, that we thoroughly enjoy. But it was finally time to deep six our 13 year old rear projection T.V. in the family room, and go with a flat screen and then, of course, I wanted to update the AVR and upgrade to Blu-Ray. Not to steal this thread, but if the 1403 may not be enough WPC, any other suggestions, keeping in mind cost and SQ?
I don't think you will have ANY issue with power. For a test I just tried my 1403 with 5 pioneer SP-BS21-LR book shelf speakers that I normally use 2 for my surrounds, and other ones elsewhere. These speakers are not very efficient at 84db sensitivity, 6 ohm. They are great sounding speakers that's why I bought 3 pair, but for the 50 WPC 1403 to drive them to any serious listening level does seem like a stretch. However, I can say, don't worry about having enough power from this receiver!! I paired them with an old 10" Dayton sub. My 1403 volume is set 0-100. I normally listen between 50-60 on the volume scale (with more efficient speakers) which I have set to max at 80 so I don't damage my hearing. I have never taken the volume beyond 65 which gives me 90+db SPL (measured). With the inefficient Pioneers (5 plus the sub) I can listen at my comfortable 80-85db SPL with the volume at no more than 65-70 without any distortion/clipping. This is in a 12 x 16 room.
I am completely blown away by the sound quality of this Marantz receiver. I originally just wanted a new HDMI capable HT receiver to replace my old H&K, and was planning to use a separate quality 2 channel Integrated amp for music. However, I am so happy with the sound quality of the 1403, I will probably cancel or postpone any further purists. You certainly can find lots of receivers with many, many more features and perceived "power" in this price range, but I don't think you will easily find a sweeter sounding receiver without spending a lot more. The 1403 lacks all the bells and whistles, but Marantz gave us the SAME SQ as the higher end stuff along with plenty of power for most applications.
In conclusion: If sound quality/cost is paramount, well, IMO don't look any further! As far as driving your Zeros, I don't think that should be an issue at all, especially with a sub taking the brunt of the power requirements . I know you have a big room, but are you listening at volumes north of 100db SPL?
