Hello,I am upgrading from Pioneer Elite VSX 21TXH to Denon 3500H. One thing that struck me immediately was the dialogues. Denon is quite thin sounding over my decade old pioneer. Denon calibration is 100x better than Pioneer's. Especially on the Sub. Never knew my sub is so good. Quite great calibration. It is just the vocals that i would prefer bit more weight. I am wondering whether it is worth using Denon as preamp only and put in my Pioneer back as the amp. Or is there some tuning that i am missing? Anyone else had similar feel when upgrading from old school receivers?
You can try by raising the centre channel trim level in your AVR by 1-2 db to make dialogues better. You can also try the dynamic volume (low), which makes the dialogue clearer at the cost of some dynamics, but it certainly helps for low bit rate content.
Also, even if you use the denon only as your preamp, the sound signature won't change drastically and you may not notice any difference at all.
