Substituting Onkyo 3007

[gorman]

Being a victim of the dreaded "no sound" problem, just out of warranty... I need to buy a new receiver.

Considering this is the second time in a row that an Onkyo amp gives me electronics related problems, I am not buying Onkyo again this time.

I'm looking at Yamaha (RX-A3010) or Pioneer (SC-LX75 o SC-LX85).

No clicks on HDMI handshaking (fed up with that on the Onkyo) and fast HDMI handshaking much preferred.

Opinions? Suggestions?

Thanks to everybody so kind as to chime in.

Speakers used: Dynaudio Audience 72 (front left and right), Dynaudio Audience 42C (central), Dynaudio Audience 42W (surround left and right), Chario Piccolo Classic Sat (height front right and left). Dynaudio are supposed to be 4 ohm but I remember reading that they are a much easier load than most 4 ohm speakers.

Edit: Sources are going to be quite mixed. HTPC with Nvidia GTX 460 graphic card (HDMI video and audio), Squeezebox (SPDIF audio), Sky satellite receiver (SPDIF audio, video so far HDMI straight to TV), Xbox 360 (component+SPDIF), PS3 (HDMI). Considering the HTPC use, it's really important that through video function works well, I don't want problems with video levels and resolution being touched by the receiver.

With that speaker system, which is very nice by the way, you need separates.

I have long experience with Dynaudio drivers.

Whilst most of them have respectable phase angles, when you get two together the impedance is nearer 3 ohms than four where the power is.

Take a look at this measurements I have in file of these speakers with Dynaudio drivers which will be very similar to yours.

If you open the file you will see that the impedance is close to 3 ohms except for the sealed box tuning peak where the power is.

The impedance does not reach 4 ohms until 300 Hz.

So I think you will fry all but the very top end receivers..

For a Dynaudio system like yours with two woofers, you are best served with a pre pro and an amp that will handle 3 ohm loads.

You have burnt out two receivers already and you might as well bite the bullet and be done with it. It will sound a lot better also.

I see the warranty is void when using the Pioneer with speakers less that 6 ohms.

The Yamaha is only specified to 8 ohms. However they state you can use 4 ohm speakers on the front left and right with the impedance switch set to 6 ohms.

However use of this switch severely limits current and power. For those Dynaudio speakers you would have to use it. I strongly recommend external amplification for your system.
