Summary: I upgraded to this from a VSX-1123 to get the Class D3 amplification and I can sure tell a difference. My home theater uses legacy Pioneer HPM-100 front speakers and I needed something to drive them properly. This fills the bill. I know what they should sound like because I collect vintage Pioneer Silver gear and have run them from a SX-1280 and the SPEC 2 Amp.
Summary: We got this unit a month ago. Although, the software was very helpful in identifying the right hdmi etc connections, it still took me some time to configure it correctly. I am connecting the unit to two old maggies. The sound is good. Love the internet radio and pandora. I wish video airplay was enabled. That's the reason I took 1 star off. You have to read the marketing material / manual carefully to figure out that you cannot stream photos or videos.
Summary: It's more than powerful enough for driving my inefficient 5.1 system, draws few watts, is quiet, and has an associated app that's actually useful and looks good (with a few questionable interface choices). It's great to be able to put it away in a cabinet out of sight without worrying about IR repeaters or the like, controlling everything from my iPad. I've only had to use the remote for initial setup and room recalibration.
Summary: So I was really saving for an Onkyo 929, but Amazon has yet to move close enough to the $900 price point I was getting anxious. When they had this puppy on the one day sale for $549, I couldn't resist. The Onkyo was actually much more than what I needed but figured I would wait a lot longer to upgrade again, just wanted to upgrade the receiver in the family room.
Took advantage of the one-day sale - happy that I did

Summary: As several of the other reviewers have mentioned, this machine went on sale a few weeks ago for $550, about half of it's normal list price. I did not have an urgent need to spend money on a new receiver as I just upgraded my tv to a Panasonic 65" plasma (they are about to discontinue) and my speakers to Klipsch RF-82iis. However when I saw a high-end receiver on sale within my price range I went ahead and bit the bullet.
Summary: I previously purchased an Onkyo TX717 at a great price however it seemed to be lacking something. Then the internet radio feature stopped working and so I sent it back. Purchased the SC-1223 and it is fantastic. Great sound, great features, added an IO Gear to the ethernet for wireless, and it will power my 4ohm speakers. Not many companies make receivers that will drive 4ohm speakers.
Summary: Ich schließe mich den fünf Sterne-Rezensionen uneingeschränkt an. Einen Stern Abzug gibt es aber für die fehlerhafte RDS-Anzeige beim UKW-Rundfunk. Die ist lückenhaft und überschreibt oft nicht die vorherige Anzeige komplett. Ich habe das Gerät zwei mal austauschen lassen, doch auch das dritte Gerät weist den gleichen Fehler auf. Na ja, dann höre ich eben über das Internet Radio.
In der Preisklasse für mein Gehör einer der besten Verstärker

Summary: Vorausgesetzt Du hast die passenden Lautsprecher, und Du hast für den Preis ausreichend Equipment, diesen Verstärker zu verwenden, dann gehört dieser zu einer der besten Verstärker vom Klang: Höhen, Mitten und Bässe sind ausbalanciert in meinen Ohren. Diese Aussage kann ich für die Musikgenres: Klassik (nur Lautsprecherpaar vorne eingeschalten), Rock und Pop (nur Lautsprecherpaar vorne eingeschalten), sowie Disco/Techno (alle Lautsprecher im DSP-Modus laufend), treffen.
