Onkyo TX-NR807 receiver or similar - amp any good?

Following my purchase of the 805 I quit looking at the various iterations of Onkyo rec lineup. I thought I heard they went with digital amps on the next series, as many other’s already had. So from the 806 on, D amps were in use. Beats me if or why.

Onkyo as with several other mass fi makers of receivers, tend to put on their best face with the numbers they a lot for their spec sheets. It’s common to see a power rating on receivers these days where the power rating reflects only 2 ch use. My 805 uses transformer output amps, and is rated at 140wpc @ 8 driving two speakers..

It did run warm for sure and I had to place it atop the rack. Adding amps to it reduced that issue to pretty much nothing and has it running now only as a second zone int and multi ch processor..

I’d suspect as with my own 805, if the speakers impedance load is fair to midlin’ that receiver of your’s is up to the task. There are reviews of the 805 online and Google will lead you to it/them.

I found it to be easy to listen to and more a music oriented receiver than a crash and bang HT unit. It could have more jump factor…. Albeit, this is surely a preferential note a bit more so than in truth. A power cord and differing loud speakers can and will make great differences there.

The flip side of that coin says it’s an exceptionally easy to live with and enjoyable to use device for film, TV, and audio, all on it’s own accord IMO. It will definitely gain more focus following run in too.

Aside from your tastes and room requirements, your 807 should do well….. only you can decide if adding the extra amps you have on hand is going to be a step up or not. Get a pair of cables on em and see what you prefer!

Enjoy your forthcoming A/B-ing once all is in place.

I will say this about that...

the primary limiting factor using an HT receiver is always going to be the preamp/processor within it. Perhaps more so than the amplifiers it uses, provided a proper speaker set is selected to mate with it.

Even adding very good amps outboard of it might not be as satisfactory a result as you could want for, ultimately.

They'll help for sure, in control dynamics and dimensionality. tonally as well.... but at some point to gain better levels of performance, akin to premium sound quality, I'd suggest some thought on separating things into two systems.

there are work arounds like adding a nice pre with a 'HT pass thru' feature but at the least, another set of ICs along with the desired pre will then be required. If another space is available, I'd definitely recommend it. Some other options are there too, but separation is purely best.

Each amp selection I have on hand has been attached to my receiver at some point. SS, tube monos, and hybrid. None of those additions equal what they can sound like with a great preamp feeding them directly off some source.

How much better can/do they sound like that over the proc/pre in the HT Receiver?

A lot! Depending upon the combination, of course, a whole lot!!

Consequently keeping things in general on a similar and accordingly level playing field when adding amps will be a big help in more areas than one, but mainly savings and performance by not over indulging by stepping too far up the amp stair case.

Changing speakers then, might be a better thought…. Though I suspect your’s are pretty good. I’ve only heard the Cremona’s, and some of the SF two ways.

Good luck
