Forget the purchasing price. Think about future expenses. Whether it is Denon 1700 or 3700, receivers will last only 3 years. Your repair cost would be approx 40k for board change after that for 1700 itself. 3700 X might work out to 60 to 75k. And the EB units more powerful amplifiers suck will be almost 50% that of an AC. So go for entry level if you dont wish to spend yet another fortune in a few years and have to decide on whether to repair it or go for a new one. But if you want more power and pre-outs which will only matter for Netflix or Blurays, very less content available currently, you must just be a wise and not so reckless spender on this rabit hole trap.
