Lets step back for the moment and verify a few basics: 1) Did you calibrate your LCR meter before doing this test? 2) Did you calibrate for full frequency range? If so, what is the bandwidth of this device? If your device is bandwidth limited to 10kHz, check to see what the accuracy is at...

Yes it is and I originally suggested this when I wrote my 5803 review. Since both receivers operate similarly with respect to amplifier assignment and zone2 audio, it can be done on both units.

The Denon DVD-5900 I am testing the RX-Z9 with does pass DVD-A and SACD via i.link. However, older models need to be modded by Denon to enable the i.Link feature. I will find out what serial#'s are affected for this.

Its funny that this hobby seems to be dominated by males, especially since women generally have better hearing. I suppose they are not as fanatical about audio as we are, they concern themselves with more important matters :o

Rip; The links have been fixed, thanks for noticing.

Over the years controversy has raged back and forth on whether brick wall filters used in digital audio (namely for CD playback systems) exhibit phase shifts in the audio band (20Hz to 20kHz). Audio critics, pundits and assorted experts have gone back and forth on this issue with out much...

I see these type of statements pop up quite often so I thought I would address it here. Do NOT attempt to compare the capability of a receiver/amp based on the volume level you adjust to. Each manufacturer uses different potentiometers with different sensitivities and scales. Many of the...

Jeff; Rest assured when I can share details with you, this will be the first place to find them :) Hang in there, good stuff is coming ;)

The AVR-3805 is without a question an excellent bargain as far as receivers go. However, the AVR-5803 is a significant step up in terms of power and refinement. One could argue buying an AVR-3805 and putting the $3K saved into a dedicated 7CH amp and that certainly has its merits. However...

While the Sunfire is a powerful receiver, it is sad to see a receiver almost $3000 cheaper have over 15dB SNR advantage under the exact same 1watt test conditions.

What is likely happening here is you have a speaker system, perhaps a 3-way where the wooder is wired out of phase from the mids/highs, to electrically sum at its crossover point. This can trick the auto setup into thinking your speakers are out of phase. This can also happen with other...

As far as I know, everything works thru Dlink3, however via EXT ins bass management and room correction don't work. Clint has the test unit so I will have him correct me if I am wrong :eek:

Octavio; Great catch! I think Clint misinterpreted the rating criteria for that category. We assign 50 points for processors that have stereo sub outs and 25 points with one sub out/mono. We will update the score card to reflect the change. Thanks. No sleep timer? Bummer, guess...

Yes I do agree Jerry. Shielding is usually not needed for speaker cables, but for interconnects and video cables that is another story. FYI, one of our contributors is an industy expert on EMC and signal integrity, Mr. Henry Ott. Check out the following cable article for more information...

Jerry; Actually I disagree here. Well designed cables should be indistinguisable sonically. The problem is just how well is well :D

Jerry, first off thanks for registering. I agree with you 100% here. However, we rarely do amplifier face off reviews for several reasons: 1) Too time consuming 2) Most manufacturers won't send gear if they know you are doing a face off 3) Usually doesn't make for good reading material...

My first question back to you, is why are you an anonymous poster? You raise valid concerns, wouldn't you prefer to give credit to your name? Ok thats two questions. The article you reference is over 4 years old and definately needs updating. Until you pointed me to it, I didn't even...

Yes, Biwiring basically uses two sets of cables to the speaker but tied back to a common amp. There is very little benefit in this assuming the one cable is of sufficient gauge and conductor spacing. Biamping actually uses two separate amps to power the highs and lows of a speaker. Rip Van...

My RX-Z9 review is turning into novel length! It will make Clint's AVR-3805 review look short ;) Seriously, I am working some tech issues with Yamaha on some stuff and will hopefully be done by end of June. I am also building a test load to measure power, but not sure if it will make this...

Jeff; Of course true biamping is when you bypass the crossovers in the speakers in favor of active line level ones. So no, the method utilized in the receiver does not realize the full potential of biamping. However, it does provide an advantage to those powering speakers that need a little...
