That's like 60% more expensive. And the Yamaha isn't that much better. It supports more codecs yes, but I'm fine with DTS and DD 5.1. From the reviews I've seen, the Z906 is better with lows and mids, with the Yamaha being better with highs.If
If you can increase your budget Yamaha will be a much better option.
Anyway, my budget is <20k. Is there something else in this budget that's better?
