The A-9000R uses four 18000 microfarad capacitors vs four 15000 microfarad capacitors found on the A-9070, has sturdier feet (same feet found on the M-5000R), a 24/192 USB input, and has quad push-pull amplification design vs. parallel push-pull amplification design. Other than that they are the same amp. I suggest you same the money and get the A-9070 and a high quality USB to spdif converter. The A-9070 was extremely hard for me to order. It was sold out everywhere and I had to special order one. I was very lucky to get one after waiting 3 months. It was the only brand new unit across all the electronic stores in the country. In terms of sound: highly dynamic sounding, detailed highs, and neutral balance. This is my second integrated amp that I have ever bought. I upgraded from a Rega Brio 3, which I sold a couple months ago. The Brio 3 was an awesome amp, but I had to walk up to it each time to adjust the volume. The biggest improvement is tighter and deeper bass and overall increase in background detail. However, the Rega's midrange is much more sweeter and delicate sounding than the Onkyo. The Onkyo is not engaging to listen as the Brio 3, which was warmer sounding, but the transparency and ability to render any genre of music won me over. The Brio's lack of power and lumpier bass was not very good for complex music such as dance, electronic, and pop music. I also prefer the Onkyo to my more expensive 170Wx9 Pioneer Elite receiver. The dual Wolfson WM8742 onboard dac is excellent and I prefer it to the Hegel HD2. My favourite feature on the Onkyo A-9070 is the ability to use it as a pre-amp, power-amp, or an integrated amp. The Onkyo is highly revealing and transparent sounding amp, so it is very picky with different types of cables. There is a huge difference in sound when I swap between different mains cables, speaker cables, and USB cables.

That alone means that it has a different poweramp alltogether..u cant just add transistors whithout creating a suitable circutry for them.Bigger caps are added to better suit the new desing.In terms of sound that means that the 9000 has better grip and a more powerfull low end.In fact i woulndt be at all surprised if it uses the same boards as the M-5000R but without the huge PSU found on the 5000.The main reason i would opt for the 9000 would be the Poweramp witch would be more suited for the RX6s(my main cadidate for speakers as ive read and spoke with many ppl who say are harder to drive efficiently by other inexpensive amps..they requiere good grip on the low freq range in order to sound theyr best).
As for USB-S/Dif converters id get one anyway(i stated in a previous post that id be getting an Audio GD DI-V3 with clock upgedes and PSU).
I agree with csq2' s assesment of the sound. Partnering needs to be done with some care. I have a cd-player with tubes and that was the pefect match for the types of music I like to listen too when I want to really relax. For anything more upbeat, I prefer to run apple lossless straight to the DAC on the 9000. Speakers where the biggest problem, not because of the amp but because of placement, room acoustics and overall aesthetics.
Not that I'm looking to buy, but this thread has made me want to listen to these amps next time I'm in my local audio retailer.
I've heard the Onkyo pre/power combination, and I liked it very much.
Observe the signature in its natural habitat.
The Onkyo A-9070 is a lot more powerful than the rated 75W/ch suggests. Don't believe in written specs. My new 170W/ch Pioneer Elite receiver could not match the sheer power and clarity of the Onkyo, especially in the deep bass area. Klipsch are consider bright and harsh sounding speakers, but I find it quite musical and smooth sounding with a wide soundstage using the Onkyo. The RX6 should be a better match with Onkyo because it should be warmer sounding than Klipsch. Also, take a look at the Stello U3 and M2tech hiFace Evo, which are on my list of excellent spdif to USB converters. And make sure to use high quality, low impedence cables because they make a big difference on the Onkyo.
Are you talking about the Onkyo P-3000R and M-5000R combo? When a Kef sales representative came to my local electronics store to give customers a demo of the new Kef Blades, I was surprised to see Kef using the Onkyo P-3000R and M-5000R to drive the $30,000 Kef Blades. I was amazed how powerful it sounded with its 80W/ch rating. My next purchase are probably going to be these! It's been 20 years since Onkyo left the hi-fi market, but their new products are well worth their respected prices.
Are you talking about the Onkyo P-3000R and M-5000R combo?
Yep. A little puzzled by the fact that the power amp looks like it can take an xlr (when using one as a monoblock), but the preamp doesn't have xlr output.
I also like the DAC 1000, which strangely enough does have balanced outputs.
I never said that the 9070 isnt powerfull enough i only said the 9000 is better how much better i cant tell till i compare the 2(witch may be a posibilty since the only dealer that sells them has both of them available(or at least they had them a moth ago the pic witch had them displayed isnt on the website anymore but im prety sure theyr still there).As for the converter ive made my choice on the Audio GD theres a huge thread about it on headfi and i even saw a comparison vs other D/D converters including the Stello the guy that tested it gave it a higher score he allso suggested the the Audio GD is just a bit better than the Audiophilleo 1+PSU combo with is way more expensive.IMO something that gets so much positive feedback cant be bad.
Dont forget share your experince when u do (might be faster than me since like i said i cant go shoping yet )
Allso someone posted something about room acoustics i wonder can i add something to the wall coating to make the room better suited/make the walls less reflexive?
Have you demoed the A-9000R with the A-9070? I want your thoughts on the A-9000R since I was only able to demo and purchase the A-9070. I have seen the Audio GD reference amps in person and the internal circuts are works of art. I wish they put a clear window on their amps to showcase the internals. Although their circuit boards look impressive, I hope the Audio GD engineers know what they're doing because it looks like they are just cramming as many capacitors, transistors, wires, etc as they can into their boards. Room acoustics is very important and bass traps do improve the sound.
Well not yet and it wont be for a few months like i said i have nowhere to place new equip now so untill i move(that might be a couple of months)i wont take the trip to demo gear(its 500 miles away)but i will , trust me i wont spend the extra cash on 9000 if i wont feel its worth it.As for room acustics i asked becouse i wondered if i can do something construction wise(new house) and that room is going to be my personal space i can make adujustments to it(except for size..thats 4.5 by 3.5 meters or 14.76 by 11.48 ft hight can be adjusted).
Although I have a store that carries them close by, seeing as I'm not looking to buy I probably won't be listening any time too soon because so much of my time is taken up by work and baby duties.
The P3000/M5000 combination is certainly a potent one. We had it on demo for just over a year and used it on a variety if speakers, including the Blades, which isn't did an excellent job with (not the best, but not bad for a £4.5k amp). As mentioned, even though it is rated at 80wpc into 8ohms, it certainly sounds nothing like a typical amplifier rated 80wpc. Dynamically, I've heard very few amplifiers to match it, its response time is extremely fast. I would still say it is outclassed by the Blades, but was an ideal amp for the Reference Series, and equivalent speakers like the ProAc D40's. there was a tendency towards brightness though, which didn't bother me, but could be a little too much with the likes of KEF Reference and PMC i-Series for some people.
I did hear the A9000 prototype as I knew the rep at the time and he wanted my opinion on it, and it is certainly a lot of amplifier for the money, and very capable too, but we didn't have one of these on demo.

Looking through more Japanese user reviews of the a-9000r, it looks like it has a similar signature to the pre-power combo and some may find it s little lean or analytical.
They always quote 140w but that is into 4 ohms. It is 75w in 8 ohms, so almost doubling its power into 4 ohmns I suppose indicates good current. Most people were very satisfied with the bass, power and sound quality.
The 9000r is analytical in the sense that it is very revealing. Partnering with warm speakers would not be a bad idea. I like the combination with the Sonus Faber venere but those are not as warm as you might expect. I am still on the lookout for a warm floorstander that is not as large as the Venere 2.5 but is still front ported (or back wall friendly) but I have not found one yet. I am very interested in auditioning Tannoy precision 6.4's or perhaps the Jade 5 mostly because their design should make them easier to place.
