Good morning all , I had a marantz 7012 avr go bad on me a while back. And i replaced it with with a Yamaha a6a about 4 months ago.
I don’t know the reason for the failure of the marantz , but sure as hell don’t want to repeat it with the Yamaha.
So am I in need of external amplification to avoid damage to the avr , but also am I anywhere close to needing more power or am I just paranoid and the receiver is doing fine on it’s own ( and no external amp needed )
So I am using.
all definitive technology speakers
9080 tower fronts
9080 surrounds back
9040 surrounds sides
SVS BP 2000 X 2
All of the speakers have a sensitivity of 92db.
The room size is 22 X 13
8 feet floor to ceiling
Listening from 13 ft
Thank you all in advance
Do you know what the failure was in your Marantz 7012? If it was a power amp failure, that would be significant information. Secondly how loud to you play the rig?
Information on Def Tech speakers is sparse, But it does have a low impedance in the major power band with an adverse phase angle as documented by one reviewer.
I think receivers have become even more problematic. Both of those receivers have NINE power amps is the case. I guess most members here think that is fine. I think it is simply a terrible idea to pack 9 amps in one case, from one power supply. Yamaha do not even dare give an impedance with the one solitary power spec. The conclusion I draw from that is that it is not fit for publication in print.
The Marantz has a power rating to 6 ohms two channels driven.
Although your speakers quote a nominal impedance of 8 ohms, that is a totally useless bogus spec. The minimal impedance is much nearer the actual impedance.
I personally do not use receivers, and never would. To me they are a concept that scream expensive trouble. So my advice is that unless you play your rig at low levels, external amplification is strongly advised.
