I’m pleased with the product and the supplier. It arrived promptly and in good shape. Hooking up the 8555 was logical and straightforward. So far, it has worked flawlessly.

My main reason for purchsing the Onkyo TX 8255 April 2008) was to hook up a TEAC CD recorder I purchased earlier. My present 1993 Kenwood receiver didn’t have the need jack for the CD recorder. I had a turntable and dual cassette deck and Pioneer 25 disc CD Player hooked to the Kenwood.
Now every thing is hooked to the Onkyo TX 8255 so I can transfer some old cassette’s and records to CD. The sound is fine listening to the radio. The main problem I have is during recording from the Teac CD recorder. Swithcing mode on the front panel of the Onkyo receiver from FM or Phono, Cassette or CD is verry confusing. For example if you were recording from the Cassette deck and want to switch to the record player, you have to press the Phono button and then you have to start pressing the Tape 1 Monitor several times until the sound comes out of the speakers. Then you have to go through the samething when you want to switch to CD or AM-FM.
Why you have to press the Tape 1 Monitor several times is beyond me. All my old receivers all you had to do was press one button, one time and that was it.
Oh well………I guess that’s thinking behind modern electronics…good thing I kept my Kenwood receiver
Incredible Value!

I replaced my ailing Sony AV receiver, which was about 15 years old and showing its age, with this Onkyo. No regrets here — it is just first-rate electronics. I have a new Pioneer turnable and a Sony carousel-style CD player connected to the Onkyo, plus a Polk Audio subwoofer and two Sony tower speakers. The sound is just nothing short of amazing. I can’t say enough in praise of the receiver — it is simple, easy to connect and a joy to use. Highly recommended!

Hi, I bough this unit from amazon.com on Jan 21 2009
It was shipped from [...]
It came in with a non working volume knob.
Both directions are down unless you use the remote
After dealing with [...] and struggling with a knob that has a mind of it’s own for a year
I am now having Onkyo fix it under warranty.
It would have been nice to get one out of the box that works!
I would not suggest this product.
Superb

I purchased this amplifier recently. I own a few older, well-regarded amplifiers (tube and solid state) that cost a lot more money when new, so my expectations were not high for this Onkyo. That said, I am stunned by how nice this amplifier sounds. I run the amplifier in Pure Audio mode (press the Pure Audio button on the front panel twice, then the blue LED comes on indicating Pure Audio mode). If I didn’t know better, I’d swear this was a high-end tube amplifier. There is absolutely no background noise. No hiss. No hum. Nothing but dead silence. It makes music with silent passages jump to life. Whether I use this amplifier to drive Paradigm Titan speakers or Grado headphones, the quality of the sound reproduction and the dynamic range is absolutely remarkable, especially bass reproduction. Using a quality CD audio source, I can clearly hear every cymbal, with all the timber, every bass note, with all the string vibration from every finger pluck. For what this amplifier costs, I can’t imagine looking elsewhere unless you need to drive large reference monitors. This amplifier is more than capable of driving anything up to full-sized floor speakers at reasonable volume. The amplifier includes an AM/FM tuner that works well enough. FM channels come in loud and clear using the included wire antenna. AM reception is a bit more difficult using the included loop antenna and its short wires, so at a minimum expect to add four to eight feet of wire to the AM antenna to get the loop well clear of any power cords. But that’s really of little consequence if what you’re looking for first and foremost is a high-quality stereo amplifier. I’ve listened to high-end amplifiers costing many times as much and few sound this pure and clean. The overall look and feel of the unit is professional grade, with just the right amount of heft. All controls have positive feedback and none feel flimsy. The volume knob is particularly nice, with a heavy, smooth action that is slow to respond, resulting in very fine, analog-like volume control. In brief summary, I doubt anyone with reasonable expectations will be disappointed. This stereo amplifier provides performance and quality well beyond its price level.
Enough Power
Rating:5 out of 5 stars
Enough power to rock any house….
Missing a “IPOD” button for easier plug and play… ONKYO BASE for IPOD has to be connected to TAPE output…
Took me a few minutes to figure it out…
Awesome receiver!!!

This is a great receiver!! I was replacing an 11 year old Sony 5 channel home theater receiver with this one. The Sony was a 75 watt x 5 and I thought I needed a little more power (and the display on the Sony was gone so it was hard to operate.) I narrowed my selection down to the Onkyo and the Harmon Kardon 120 x 2 receiver (can’t think of the model number) solely on internet reviews. The price of the Onkyo ultimately sold it (over a hundred cheaper at Vann’s on Amazon.) This thing is very powerful, makes me wonder if I was really getting 75 watts out of the Sony. Looks very sharp and is very user friendly for listening to music. Want more bass or treble, just turn the knob, you don’t have to go fumbling through menus and all that nonsense. Tuner pulls in stations that I couldn’t even touch with the Sony (not to knock the Sony cause I got a ton of use out of it and it still serves duty in my garage.) CD’s, mp3, radio, and P3/movies all sound great through this baby!! For under $250 I don’t think you can touch it! BTW it is powering 2 JBL ES 90 speakers that call for 110 watts RMS. These speakers each have 2 8″ woofers and I think the Sony just had a hard time pushing them properly, but not the Onkyo.
Good deal

My trusty 23 year old TX-108 model finally quit and I was so happy with it that I bought another Onkyo.
On the plus side, the new model has heftier speaker switches. On the 108 the speaker switch became increasingly intermittent during the last few years.
On the negative side, I miss several features. The loudness control is missing, but the built in tone controls can be used.
There is no forced monaural switch. All FM receivers are more sensitive to interference from alternate channel signals in stereo than in mono. I listen to far away stations that require this mono mode to get rid of the interference.
There is no way to connect an equalizer. In the 108 you put it on the VCR sockets and you could select VCR along with any other source you want. Not so on this one. I did the next best thing and put it between the CD player (which I spend the most time listening to) and the CD input to the receiver.
Correlated with the above, if you have a three head tape recorder, you cannot monitor the tape output while recording, only the source output.
The main volume control is inconvenient. It takes about five turns to go from zero to full volume.

I was worried this receiver wouldn’t have enough power to run my Dan Queen speakers which are power hogs . My previous Onkyo had 150 watts per channel. This one does just fine power wise and has a lot more excellent features.
Great old-school home theater/stereo receiver
Rating:5 out of 5 stars
The most important fact I can give here is that our other Onkyo 2-channel receivers have lasted a long time. Our Onkyo TX-84 gave us 22 years of flawless service before it needed a repair. And our Onkyo TX-8211 has given us 12 trouble-free years so far. For this reason, and because Onkyo delivers audiophile-quality sound at a low price, I recently purchased the TX-8555.
It has not let me down. Our music sounds great on it. Movies are a thrill to watch with it. Best of all for us, old components work well with it–no need to run out and buy new stuff just so it’ll be compatible. Our VCR (circa 1990), TV (1995), and DVD (2003) run nicely through the TX-8555, as do our speakers (1987). And setup was simple; it took less than 10 minutes to swap out our old receiver and insert this newbie. No new wires or plugs were needed for the swap. You do need a dock, though, to run your ipod on this machine. Docks are sold separately.
Affordable and really good.

I have had my unit since Jan. [I lucked out on the $199 + free shipping deal.] So, what do I think? The unit works well and delivers value. Phono section is quiet and I know because I USE it. The FM reception is sensitive and relatively noise free – I have a HD tuner to compare it too so I know. AM is simply excellent as well. It seems ruggedly built but has finesse when operating the controls. My experience with Onkyo’s in the past was that they had a clean and accurate sound that leaned to slightly warm. This unit seems a bit cooler. I also considered HK but the price won me over. This is for my second system in the bedroom. Remote is easy to use and manual is well written. Have not used Sirius/XM though. Recommended highly.
ONKYO TX8555

RECOMMEND TX8555 AS BEST BUY IN PRICE RANGE FOR THOSE SEEKING STEREO RECEIVER WITH PHONO INPUTS. EXCELLENT SOUND QUALITY ON ALL INPUT MODES (PHONO,CD,TAPE,FM AND TV/DVD) WITH AMPLE WATTS TO POWER TWO TECHNIQUES SB-CR99′S, WITH SUPPLEMENTAL BOSE SURROUND SYSTEM. FOR THOSE USED TO THE OLD A/B SPEAKER SWITCHING, REAR PANEL CONNECTIONS AND FRONT PANEL CONTROLS A BIT CONFUSING, REVIEW THE MANUAL AND DEAL WITH IT, OR HIRE A 15 YEAR OLD. FM STATION PROGRAMMING EASILY ACCOMPLISHED WITH ALPHA/NUMERIC KEYS, REAL BASS/TREBLE CONTROLS WITH “PURE AUDIO” CONTROL ALLOWS FOR SOUND TAYLORING TO FIT YOUR INDIVIDUAL SOUND TASTE. TX8555 IS THE TECHNOLOGICALLY IMPROVED VERSION OF YOUR 80′S VINTAGE PIONEER RECEIVER. BUY IT YOU’LL LIKE IT.

Horrible tech support, cheap construction. Sounds terrible. Contacted Onkyo tech support they suggested that I return it to amazon. This thing was dead out of the box. I ordered a new one from Amazon, the left channel worked on and off, until it died. Again, contacted Tech Support, they know nothing. Purchased a Yamaha RX 497 and I love it!
PLEASANTLY SURPRISED

Like many reviewers, I was replacing an old tube receiver, a 30+ year old Realistic. I feared I would never be able to replace that warm, rich tube sound, but this reciever surprised me.
I consider myself a bit of an audiophile, I’m the tyoe who uses 10-12 gauge speaker wire, so I’m picky about my sound. I first set up just speaker A’s and then added speaker B’s and did not notice a drop in sound quality. I have found that having the voluume set around 35-40 is more than enough for my one bedroom condo. I did try it at 60 and did not notice any distortion in sound. I listen mostly to classical music, and there was no hum during soft passages.
I would have rated it at a five, but there are a few disappointments that have nothing to do with the sound quality. This model seems to cater to the user who is replacing their ancient receivers, so I would have expected some provision for compatibility with older connector tyoes.
One reason I selected this model was that it supported phonographs, but it doesn’t support turntables that get their power from the receiver, via 15 volt AC/DC using a pin connector. RadioShack doesn’t carry a 15 volt converter and I haven’t been able to find one online, so I’m going to have to buy a new turntable.
I have a perfectably good equalizer, but there is no way to connect it to the ONKYO. If ONKYO isn’t going to provide an equalizer, then they should provide a means to connect external ones. In order to reproduce the equalizer sound that I was used to, I had to turn the bass and treble knobs almost all the way up. As others have noted. there is no midrange adjustment.
If a tuner wasn’t included, I would have had a problem connecting my old tuner. It has a ribbon connector, and there are no provisions for that.
Although I measured carefully and the stated width was the same as my old receiver, this one was 1/8th of an inch too wide to fit into my stereo cabinet. I had to put it on a small table next to the cabinet. At least I won’t have to worry about heat buildup!
Overall, I am happy with this receiver. I have only had it a week, so can’t attest to it’s reliability. Set up was easy except for the above mentioneed limitations. If you have straight forward connections, you will not be disappointed with this model.

I’m very pleased with this receiver. I’m about as far from a “techy” as I can be, but it didn’t take me too long to get it all set up with the new HDTV, CD player, DVD and speakers. I’m still learning about all it can do but at this point I feel it was a good choice for the money. Looks nice, too!
Love my Onkyo
Rating:5 out of 5 stars
I LOVE this product. For 12 years, I had a top of the line Harmon Kardon, which I loved, but it died. I was skeptical about paying so little for the Onkyo, but there were so many good reviews. Well, they were right. Although there may not be quite the quantity of sound as the Harmon, the quality is fantastic. I listen to a lot of classical music, and the highs of violins as well as the bass factor are excellent. I live in a small condominium, so I don’t really need tons of sound. I have surround sound speakers for my movies, and it is FABULOUS.
Great product; Great price
Rating:5 out of 5 stars
I bought this receiver to drive a multi-room speaker system, and allow me expansion for surround sound, CD player, DVD etc.
This fits the bill without breaking the bank.
This also will allow me to hook up Sirius or XM Satellite radio.
There are plenty of inputs for other audio/video gear, including a turntable.
- iPod integration is easy with an iPod dock (sold seperately)
- 100 watts x2 (stereo) into 8 ohms at 0.08% THD
- Direct access tuning
- 40 AM/FM presets
- oversized power transformer, filter capacitors, and heat sink
- Pure Audio/Direct mode for a cleaner sound
This product is worthy of all 5 stars.

Great product at a great price. Works great with my HD TV for a home theater and not overly complicated. The subwoofer output makes for a great sound. It also has a phonograph input which includes a preamp to play all my old albums. I also like the remote control for the volume.

This is a fantastic receiver. It picks up stations with the VHF antenna that come in crystal clear. It is also awesome hooked up to the TV for surround sound. Movies are much more fun to watch, it feels like you are right there. Terrific product!!!
Tech Support ?
Rating:1 out of 5 stars
If you plan to buy an Onkyo product don’t count on tech support of help. I purchased the TX-8555 and a Polk subwoofer from Amazon, who’s service was excellent, and connected them using the single subwoofer port on the receiver. I can’t get the sub to work and suspect the receiver has to be set up through the remote control.
The remote control, however, seems to be stuck in zone 2 mode. The manual offers no help and for 3 day I have not been able to reach Tech Support.

Have had the receiver for a few weeks now and just love it. It is a solid piece of machinery, very heavy and will get hot, so you probably don’t want to park anything on top of it, or park in on top of anything. Lovely to look at in the front and the back is all business — more plugs than most of us might ever use. (right now am just using CD and tuner, may add DVD and TV later.) The remote is a nice add-on, and could help keep the fingerprints off the receiver, an added plus. Of course, the reason I really this receiver is the way it sounds; it really makes the music glow. My old speakers have never sounded so good.
Had it one week and it quit
Rating:1 out of 5 stars
We bought this receiver and within a week we had problems with it. The volume wouldn’t come back and then it finally wouldn’t come on at all. We had to unplug it from the wall every time we used it so it would come back on. I would not recommend this one at all. We also didn’t think it had much bass to it either. I know Consumer Reports rates this brand highly but I’d never purchase another one. Amazon was very good at their return policy and refunded us the price plus the full amount of postage it took to send it back. Amazon is the first place I look and purchase. I’d give this product a zero if I could.
Decent audio that won’t break the bank.

I don’t know why it is so hard to find a reasonably priced stereo receiver but after searching high and low for something to replace my Carvin TM 35 amp and preamp I settled on the Onkyo TX-8555. I wanted something that would give me enough inputs along with a phono input that did not cost and arm and a leg and have decent sound quality. After setting up the unit into my Klipsch speakers the sound was different from the Carvin, not bad just different. The Onkyo did not over pump the bass frequencies and once the volume level was set at a comfortable setting, the sound was pleasing. I plugged my Sony DVD player and played a few discs: Beggars Banquet in SACD and Neil Young’s Greatest Hits in High Res and both sounded amazing. Regular CD’s sounded just as good as through the Carvin.
This is a basic unit with very basic controls, which is fine by me. The set up time took about 15 minutes. In addition, the price was just right so if you are looking for a decent quality integrated receiver that will not break the bank then look at this.
Where’s the great sound
Rating:2 out of 5 stars
I have owned a Kenwood Integrated Amp KA-58 for 20 yrs when I started having trouble with it. The sound was full with great bass and treble ranges that sound great in low or high volume. To replace it, I purchased a Sony STR DG520 at Best Buy, but it didnt come close to the sound quality of my Kenwood, so I returned it. I read the reviews on Amazon about Onkyo TX-8555 having great sound, so I ordered it, expecting the same quality as my Kenwood, but Im very disappointed. It sounds smothered, some of the instruments you cant even hear. Songs on my cds sound very different being played on it. I cant believe how hard it is to find a good receiver.
