Question re power output of these Onkyo Receiver

Jaap74 · 27 Jul 2020 at 02:35

I recently upgraded from B&W bookshelf to floor-standing B&W 703 S2 speakers. They are in a 5.1 system with a REL sub. I currently have this Onkyo receiver which is about 13 years old:

Onkyo TX-SR805

manual : https://www.intl.onkyo.com/downloads/manuals/pdf/tx-sr875_805_manual_e.pdf

I feel that the receiver is lacking a bit of oomph with the new floor-standers, I mainly listen to stereo and 5.1 music, I don't watch very many movies. How does this new receiver compare in terms of power ?

Onkyo TX-RZ1100

manual : file:///C:/Users/cdudeck/Downloads/Manual-TX-RZ1100-BAS-ADV-En.pdf

I know power ratings can be fudged in terms of terminology used so any insight is appreciated.

Thanks

You're not trying to bi-amp the B&Ws from the receiver by any chance, are you?

Yes they are bi-amp'd or bi-wired or whatever it is called.......

Good suggestion however I have a very large 5.1 music collection so play about 75% stereo to 25% 5.1 so would forever be switching between the receiver / stereo amplifier

I use Roon so like the fact that I can play anything from that via the receiver

I should have mentioned that my current receiver is on it's last legs. Only 2 HDMI inputs work and sometimes the surrounds don't produce any sound until I turn it off from the power point for a few minutes. Therefore getting a new receiver and separate amp for the floor-standers is not an option.

Wow Lucid, so many assumptions in your post above. I did appreciate your detailed reply, it was full of good information however I must say that in over 10 years on OCUK I've never received such a condescending reply to anything I've posted.

Thanks to the other posters who gave an opinion in a humble and friendly manner, much appreciated.
