Looking to power my Rega R9's

@ethos123 - Thanks again!  I have a quick question regarding my Yamaha receiver.  It doesn't have a pre-out.  A pre-out isn't necessary in this situation, correct?  Would I simply run audio RCA out to HTB/Theater bypass rca in?

Then run the R9's exclusively with the integrated amp (let's say  Parasound Halo Integrated) exclusively for stereo digital & vinyl playback?  When I want surround sound, I have both boxes (receiver and integrated) powered on?  Just trying to get a grasp on the logistics of how this all works.  

Thank you again!

@yogiboy  - My concern is the Yamaha 3070 will not provide enough power to the R9's.  I'd rather just get the 3070 and call it a day, but I'm concerned that the R9's need a little more power.  I wish someone had the R9's and a 3070.

My bad, the user manual for your receiver is shared by the RX-V773 and I mistakenly looked at the diagram for that model instead and thought yours had pre-out RCA connections. Unfortunately, the "Audio Out" RCA connections on your model are for connecting recording devices only and not for a setup like I recommended. Very sorry for my mistake.

The 3070 will definitely be a step up. Whether it'll be a big enough step to justify the price, only you can decide... but worth a shot if you buy from somewhere with a decent return policy. Another nice thing about trying it is that since the 3070 definitely does have pre-outs, you can add on an integrated amp down the road if you find yourself craving more and as budget allows instead of being at the end of the road with it. 

Apologize again for steering you down the wrong road.

@gloco I have a suggestion: if you can't afford an Osiris, how about a used Rega Elicit-R?
I don't know the specs of the R9, but the Elicit R puts out 105 watts into 8ohm, 127 watts into 6, 162 into 4.
Unfortunately, it does not have HD bypass, but I heartily agree: go for a good 2-channel amp.
There's an Elicit-R for sale at The Music Room for $1700. I can vouch for it: it used to be my amp. I traded it in at TMR for a preamp.
My old Elicit-R was put in storage when I went into separates; I want it to go to a good home. It was pampered in a smoke-free, kid-free, pet-free home. If I had room, I'd still have it.
No, I'm in no way affiliated with TMR; just want my amp to get the use it deserves.
That's my plug.
But, there are many good 2-channel options out there. Look for those.

@ethos123 - No worries at all!  I really appreciate all the guidance you and everyone else provided.  I think I may try a Yamaha 3070 from Amazon - If it doesn't do the trick I'll simply return it and then look for a used receiver that has pre-outs and grab a 2-channel amp for the R9's.  

Thanks again!
