This thread has been helpful to me. I have been looking at new equipment in the $4k price range for the entire system. I did several listenings over the past few weeks. Monday the wife and I went to do some critical listening and decide on a receiver. We listened side by side to a Denon 3313CI, Marantz SR6007, and the NAD T757, all in direct mode. We used the PSB T6 as the speakers, currenty my choice to buy. The Marantz and the NAD sounded better than the Denon on most of the music we brought. There were other areas where to my ears the NAD bested the Marantz. At the end of the session we purchased the NAD T757 (the wife was getting me the receiver as a Christmas present).
I am still trying to decide on speakers. I like both the PSB T6 and the B&W 683, but I think I will start a new thread, or continue on another thread on the topic.
Thanks!
Even in Pure Direct Mode, it's hard to say one AVR sounds better than another when none of them are level matched & double-blinded. All 3 are equally good.
The Denon & Marantz will probably have better measurements like SNR, Crosstalk, THD, & Power Output, but the NAD probably has more brand prestige.
Electronics are a lot simpler than speakers. If one component measures Better, there's no way it will sound Worse in a fair fight (level matched, DBT, etc).
I believe Denon usually has lower voltage gains than both Marantz & NAD. So with the same volume settings (like -20dB on the Master Volume Knob), the NAD & Marantz will sound louder than the Denon. Even a 1dB louder level will favor the NAD & Marantz over the Denon. Thus, level matching is crucial.
I recall changing out a cheap Denon with a cheap Pioneer AVR (same speakers, no level matching). With the same master volume setting, the Pioneer was louder than the Denon. So without level matching, it would be no contest; the louder Pioneer would win easily.
The PSB will measure better than the B&W, but the B&W probably has more brand prestige.
