4 out of 5 eggsOwner for 3 years

Pros: - Sounds is amazing
- Product was cheap for what you get in my opinion
- Loads of HDMI ports

Cons: - Cheap cabling (easily and cheaply replaced on monopricee dot com (remove the last "e" in that because of newegg's dumb filter)
-Sometimes the speakers don't... load? when switching inputs. It's like the system didn't detect the input that I had just been using so I had to constantly reset the system.
- No fan: If you put this in an enclosed space I'm very positive it will overheat. I'm quite surprised by this and can't help but wonder if that is what eventually lead the system to fail. I've contacted Onkyo about this (literally just now) and will update once I receive a response from them. In the forum post I linked someone mentioned that Onkyo replaced the system but the customer had to pay for shipping. Overall not a bad deal. I just want my system back :/

Other Thoughts: I've owned this system for 3 years and yesterday. It died. No idea what happened. I went to bed watching a movie, shut everything down like normal, and woke up to use it and it won't load anything. I can't update because the network option is greyed out and I get 0 sound. It's the same exact problem listed on the Onkyo forums here:

I would say it's a fantastic system otherwise but right now it's a paperweight. Mind you this is after 3 years of almost daily use but it's been plugged into a very nice surge protector for the entirety of it's life and has never been dropped, damaged, or had anything spilled on it.

5 out of 5 eggsONKYO HT-S9400THX 7.1-Channel THX Certified Network Home Theater System

Pros: I bought a Samsung System from HH Greg before I saw this item. I returned Samsung and bough this system. The package was delivered on time, no missing items, everything as described on the web site. It is easy to instal and configure. It gives my family the actual feeling of watching a movie in the theater! We have watched so many movies in the last couple of weeks! It is a great system

Cons: Nothing

5 out of 5 eggsONKYO HT-S9400THX 7.1-Channel THX Certified Network Home Theater System

Pros: Finished the basement and just installed the system. Watched the first movie last night. It was an awesome experience! The entire hose is shaking with low noise setting! Even a pin drop could be heard. This is from an HD movie we were watching it on the internet. I have just ordered my Blue Ray player. I am excited to think how wonderful it would be watching movie on the blue ray player! Love the system. It was easy to install. Easy to hook up components. 2 HDMI IN ports make it very useful.
Shipment was perfect! No parts missing, on time. No complaints at all.

Cons: None

Other Thoughts: Would highly recommend this product.

5 out of 5 eggsAll around solid system

Pros: Refined finish, solid hardware, simple design, AMAZING sound, easy setup, included microphone for auto configuration, color-coded wires, huge subwoofer

Cons: Cheap wires (get your own--most people do anyway), no included wireless connectivity, slight speaker hiss at 82db THX reference volume, wimpy speaker mount brackets

Other Thoughts: Newegg delivered this incredibly fast--this huge and heavy box came a day before some little stuff I ordered on the same day from "the major online retailer." Box was in perfect shape, no damage. I was pleasantly surprised at the finish on the speaker boxes. It's like a black veneer with a slight sheen, very elite looking. The subwoofer is HUGE. It ate my old 8" subwoofer and spit out the wires. Setup was easy but I'm glad I have banana plugs coming because wiring was a pain using the little screw knobs. No distortion in sound even when I took it to 95db which nearly blew my ears. Incredible sound. Tested some 7.1 content and was stunned by the crispness and tight bass, even though this was a test with the speakers in a small surround config on the floor with me sitting in the middle. Bass thumbs your chest. My dog walked through the room during a Propeller Heads song test and EXPLODED.

5 out of 5 eggsAMAZING system

Pros: Everything included in the box, wonderful sound, incredibly powerful.

Cons: Fairly clumsy menu interface.

Other Thoughts: I'm in love. This is an amazing HTIB. I only use that term because it all came in a single box; the receiver is a standalone Onkyo. It's incredibly powerful, especially the subwoofer. We tested it out with Star Trek (2009) and it literally shook the entire room.

It's got just about any connectivity you could want, including 4 HDMI ports. The on-screen overlay is well done. One of my favorite parts, though, is the built-in networking and apps for Pandora, Slacker Radio, even a DLNA client! It connects very well over our home network to the WD MyBook Live and streams music very well.

One of the complaints I read in a lot of the reviews I looked at before buying this was that the speaker wire included was 20 or 22 gauge. While I did purchase some 16 ga. speaker wire, I haven't used it yet and this thing still sounds unbelievably good.

The Audyssey self-calibrating setup included also really helped to dial the system in for our living room. I really can't say enough good things about this system. It's a truly enormous box; I had to have help bringing it into the house after UPS delivered it (with barely any damage, and that only superficial. It looks like I was lucky) and it weighs over 130 lbs.

All in all, I am VERY happy with this purchase (especially with Newegg's pricing!) and would recommend this to anyone else in a heartbeat.

5 out of 5 eggsGreat Sound with a good price

Pros: The system sounds awesome for what it is. Plenty of features and bells and whistles for even the most techy person. Very easy to setup and get going. On Screen Display works great over the HDMI. Sounds amazing, great highs and super deep lows especially in the THX modes.

Cons: Wires suck toss em. Remote is not very good or intuitive. Speakers are kind of big, was expecting them to be a bit smaller I guess. Front speakers are kind of short was expecting those to be a bit taller.

Other Thoughts: Very great system for the money.

4 out of 5 eggsNice HTiB!

Pros: The "package" (huge, 135 lb. box) arrived in great shape. Setting the system was easy, save for placing the speakers in my odd-shaped living area. The color-coded wires made getting the speaker hookup a cinch. The price was about $370 below MSRP (and is $50 lower just a couple of weeks after I purchased mine. Drat!). The functionality and sound beats my old Panasonic system hands down and for about the same cost (the wireless subwoofer quit working and the "wireless" rear speakers never did put out enough volume to hear them well). Some descriptions state that this system comes with a 10" subwoofer but this one came with a 12" which can cause the whole house to rumble with some movie sequences. I replaced the puny speaker wires with 14 AWG speaker wires which made a noticeable difference in both output and clarity. Streaming music from the included programs/sites was a piece of cake and sounded great. Haven't tried to stream video yet and doubt it would be that good as my wifi internet service isn't particularly fast. Software updates on the excellent receiver was also easy. Most reviews I've seen for this system have been very positive and I have to agree that it's definitely worth the money.

Cons: 1. The front display panel on the receiver does not work. Cost me $30 to ship it to a regional Onkyo service center for repair. Can't say yet whether it'll be fixed or how long it will take to get back. Newegg will only exchange the whole system, which would be a real chore to re-package and get shipped.
2. Speaker wires are way too small, as they are in most home theater kits.
3. System can take quite a bit of time to warm up and function. There's been many times when I want to turn on the TV and have to wait what seems like several minutes (probably not really that long but seems like it) before I can even use the remote or have sound come from the system.
4. $50 price drop shortly after I bought it would've covered my $52+ sales tax.

Other Thoughts: The speakers, though good, could be better. Most of the weight is in the relatively cheap enclosures and mounting them required replacing the chintzy keyhole mount with a beefier setup. The receiver is definitel a step up from almost any other HTiB on the market. Overall, this system is a good investment.
