Marantz + Older Denon Questions
Just ordered my 6012 yesterday (deep discounts...weird it is cheaper than the 6011). Anyway, I am replacing my ~10yr old Denon AVR-990 in the process. I am a little concerned that I am going from 120 / ch to 110 (and 0.05 to 0.08 thd, but I am assuming I won't hear that), and I am floating the idea of maybe in the short term using the 990 as a power amp for the 6012, or in the longer term getting 4 speakers to go 7.1.4 atmos and using the 990 to fill in the gaps (I have HSU 5.1 + ELAC tower L/R atm). I am curious if anyone would comment on:
-- Is this a good idea, or should I forget about this and focus on getting a separate power amp down the road for quality / functionality.
-- If I do the short term idea of powering the 7.1 soley through the denon, is this an effecient use of power? Would I notice a difference power / volume wise?
-- How much of the sound color is from Marantz pre-amp vs post-amp, i.e. will I get all of the coloration from Marantz if I go pure direct with AVR
-- How much more life would I have on the AVR for this purpose?
I am also curious to know if anyone knows, besides just pure direct which will happen, if I can disable volume controls / anything else on the 990 to functionally make it a pure power amp. Thanks!
