Hello all,picked up a 590 about 8 days ago.I bought an extended warranty on an hdtv 5 yrs. ago from abc warehouse,I never had to use the warranty on the tv so I got half of it back towards the 590,ended up being about 65% off ,plus the salesman came down $30.00.I`m a happy camper! Considering this is denon`s entry level avr the sq is excellent.I see where denon saved some weight(money) on, no ac outlets,analog multi-channels,s-video,and a stamped metal main heatsink instead of cast aluminum.The power transfomer and capacitors appear to be the same.I actually like the fact that the 590 doesn`t upscale,my tv does a better job. The 590 sounds good in just stereo with music, much better with dpl2. dts neo 6 seems to sound better with the 590 than other avr`s i`ve had. the manual is still a nightmare,thank you mr. batpig!!. I`ll go out on a limb and say that considering the features and performance that you get with the 1610/590 it is one of the best avr values on the market!
