Marantz NR1605

This receiver just came out and seems like very capable/great value from Marantz:

They promise 50wpc into 8 ohms, but there is also a mysterious 'front bi-amp' mode they recommend using to improve 2ch listening.

Do you guys think this would be an ok "starter amp" for a set of Sierra Towers? It has pre outs so I could eventually use it to drive a much more powerful amp... but can I get by on 50wpc for now?

Calculating from the stated anechoic sensitivity of 89dB @ 2.83v / 1 meter (aka 89dB @ 2w/1m for a ~4ohm speaker)

91db = 4w
93db = 8w
95db = 16w
97db = 32w
99db = 64w

So if we assume that my room is not anechoic, and the mysterious "front bi-amp mode" actually produces a little more than 50wpc @ 8ohms (perhaps ~70wpc @ 4 ohms?) I should be ok to crack 100db @ 1m. Which sounds like plenty in my little living room...

For what its worth, I drive my Towers and Horizon RAAL with a Marantz 1603 w/50 watts per channel. For normal listening to music in a small living area in a town home it is more than adequate. Dave confirmed that it is fine on a certain occasion.

Oddly when I tried to play movies I feel that it is lacking the power some times. You might find the same unit much cheaper on accessories4lessDOTcom. They say its refurbished but most often its not.

Interesting, I wonder if it's fine for driving just the towers when you're listening to music, but when it has to drive the center as well for movies it gets overwhelmed?

I recently added a center. The issue with movies was existing even without a center. It just that I have to push the volume high up to reach the same decibels ( to my ears )

Just a note of observation: I like the look and feel of the Marantz slim-line receivers more than their full-size lineup, but keep in mind that the slime-line models basically are making you pay extra for less. I only recommend them if you *really* need the slim-line chassis.

Denon and Marantz are owned/operated by the same management, and their receivers share a significant portion of their internal designs. The Marantz line generally has nicer front-panel cosmetics than the equivalent Denons, but they cost more and often have fewer features.

For example, compare the Marantz NR1605 with the Denon AVR-X2000 (or the newer AVR-X2100). The Denon is bigger, but for the same (or even less money) you get more power and a better version of Audyssey with the Denon. So with the Marantz you're paying more for the cosmetics. Most of their circuitry is similar (if not the same), so there's no performance advantage to the Marantz at all (in fact quite the opposite).

As for the bi-amping option, it won't do much of anything except appeal to those who think bi-amping gives more power. It doesn't -- or does only a tiny bit, which wouldn't be audible or worth bothering with at all.
