I want a new receiver - which one?

[Xourque]

Hello everyone!

Simple question: What receiver should I get?

But alas - that is not a simple question. Silly me!

Here is what I currently have:

Receiver: Yamaha HTR-5930 5.1

Speakers: Radiient Calypso 5-speaker set (discontinued - they actually no longer distribute speakers)

* Front Left & Right:
-- 80Hz - 20kHz
-- 8 Ω nominal
-- 120 W short-term peak, 60 Wrms continuous
-- 90dB/w/m
* Center:
-- 90Hz - 20kHz
-- 8 Ω nominal
-- 80 W short-term peak, 40 Wrms continuous
-- 86dB/w/m
* Rear Left & Right:
-- 90Hz - 20kHz
-- 8 Ω nominal
-- 60 W short-term peak, 30 Wrms continuous
-- 84dB/w/m

Subwoofer: Energy ESW-V10 10" 300 Watts RMS (discontinued)

TV: Samsung UN55B7100 55" LED

Blu-Ray player: Samsung BD-P3600

That is what I have already. As you can see, my receiver is out dated and definitely does not have the HD decoders to take full advantage of my Blu-ray movies. My speakers aren't the best either but they still sound quite nice (any opinions on the speakers is appreciated, too!)

Here are the variables that would effect my decision making process on a new receiver:

- It has to be at least 5.1
- Must have DTS-HD/Dolby True HD
- I really like the idea of self-tuning audio technology, such as Yamaha's YPAO or Denon's Audyssey
- $350 is how much I'd like to spend with maybe $400 being max
- I don't care about analog inputs and up-scaling
- The limitations of my speakers

Some receivers that have caught my eye are:
- Yamaha RX-V465
- Denon AVR-590
- Pioneer VSX-819H-K
- Pioneer VSX919AH-K

So with all that said, what are your opinions?

Thank you in advance!
