I bought this amp mainly for an Audio Techinca Lp60 turntable and to drive a couple of Polk monitor 75Ts. Before this amp, I had purchased a Sony STDR 130 (for the same price) but later returned. After listening to the Sony and trying a frustrating hundred times to tweak the right sound from the Sony, this Onkyo seems heaven sent. All the features Sony lacked for a basic 2 channel receiver, the Onkyo fills in.

Powerful with Crystal clear Highs and Mids.
Rich well defined bass (not boomy and undetailed).
Phono input for turntable (a big thing for me).
Preset FM buttons, for quick change, on front panel , for FM lovers .
Independent bass, treble and balance knobs and a volume knob that rotates, when you use the remote.

A single input rotary knob would have been better than the several input buttons for CD, Phone, Line 2 etc.
Front panel lettering hard to see.
A bit bulky for some tastes.

Being on our local Weight Club gym board and loving the world of audiophile, I re-set up our gym audio system. Now, this is a huge volume of area overcome by a lot of grunts and mechanical movement but this Onkyo stereo amp prevails. Using Polks as the high efficiency drivers, the constant music of all varieties fills the building with great sound quality. Used to have complaints of inadequate volumes, but not anymore. Some might look at the 50 watts as weak but don't forget that's like 125 Sony watts. Every watt is high current and solid resulting in the user not having to crank it up to satisfy the ear. Been pumping out tunes at about 60% power output @ 20 hours a day seven days a week for over two years now and everything as perfect as the day it was born from the cardboard box!

I bought this to use with my vintage Thorens turntable as it has a phono stage. The amp works fine but doesn't seem to have much power. I have to turn it half way to max to get a decent listening volume. My speakers are older JBL towers rated for 150watts/channel so the amp should drive them easily.

This unit (which I did not buy from Amazon) worked with normal use for about 8 months. Then the sound began to cut out after a few moments and the unit overheated. I took it to an authorized repair shop, which quickly went bankrupt. I finally got it back, but it still had the same problems. Paid an experienced electronics repair man $175.00 to fix it. Although he changed several parts, I now have sound from only one speaker. The Onkyo Head Office in the States brushed me off. I have had so much aggravation from this defective piece of junk. A quick web search will show that many others have been burned by this company. Do yourself a favour and don't touch Onkyo products with a ten foot pole.

No frills, good sound Sept. 13 2008
By Mike Ventura - Published on
Verified Purchase
This receiver replaced a Sony STR 397 that had a continuous static problem that was never fixed. I gave up on the Sony and bought the Onkyo. I use it to power two Polk tower speakers hooked up to my HDTV and DVD player.

The receiver is basic, no frills. Bass, treble and balance controls are on the front panel. There is no loudness control. There are multiple memory settings for music stations. All the standard connections are in the back including an input for an iPod (docking station extra). The tuner works well and has standard scanning for stations.

The receiver is rated at 50W per channel. It is plenty adequate for the Polks. The sound is clear and unvarnished. It produces a crisper, cleaner sound than the Sony.

For sound reproduction without lots of frills and buttons, this has proved an excellent choice. I am very pleased with the item.

Once again, I have to complement Amazon for having excellent pricing and incredible free shipping that is fast.

The amazing invisible amp. Revisited Oct. 31 2008
By Arthur Hampton - Published on
Verified Purchase
I bought this receiver to replace a fine amp, preamp combo that was 25 years old and had served me well (a NAD). So this one has a tuner built in - oh well. I'll almost never play the radio. But this unit is just amazing. It impresses me as being totally transparent. There is no noise, no hum, no nothing to let me know that I'm listening to a cd, unless the signal is on the cd or other audio source. Either stuff has gotten a lot better in the last 25 years, or my hearing has deteriorated. Heh heh - both are true. I've only had it two days, so I know nothing of durability. It's driving a couple of IMF speakers which are quite power hungry - no sweat, they just sing beautifully.

Update: Well, it's been over four years and this beast has been terrific. The only way I know it's on is because there is that led display. It gets left on overnight because I forget it's there. Just what I was looking for in an amp.

A Very Good Two Channel Receiver Jan. 8 2009
By S. Letterman - Published on
I would like to offer my own personal opinion regarding my purchase and use of the Onkyo Receiver model TX 8255. Right off the top I must admit that I am more pleased with this receiver than I have ever been with any other receiver I have owned. I go back to the days of tube type components and I have owned a couple of the old style Marantz receivers, a Yamaha and a Harmon Kardon as well as Mackintosh components over the years and all have performed to varying degrees of satisfaction. Each unit had it's pro and cons as they should. Recently I had an issue with my last receiver and had the problem repaired on a number of occasions but the repair only lasted maybe a year and then I was back to the same problem. I decided that it was time for something else and basically what I wanted was a simple two channel stereo receiver that would power my Paradigm tower speakers and sound decent with no performance issues as well as have a very acceptable AM/FM receiver section. After doing some homework I decided to try the Onkyo Model model TX 8255. In a nut shell the Onkyo exceeds all my expectations. It has more than enough power to drive the 8 ohm Paradigm speakers even above normal listening levels with no noticeable clipping. The receiver section draws in many stations although I must admit I reside in a medium city environment so I would assume that there would be no problems. The unit and remote are very user friendly and cleanly laid out. The only thing that I miss and would have like to have had was a midrange control. Other than that I have no problem saying that I really, really like this unit and expect to stay with it for many years to come.

Nice receiver but controls could be easier to see Dec 31 2009
By lovesummer - Published on
Verified Purchase
I was glad to see that there are still some two-channel stereo receivers that aren't home theater setups. Having 40 radio presets is also nice, and a large volume KNOB, not volume buttons, is fantastic. I just wish the controls had bigger buttons and much bigger labels with more contrast. I had to get a flashlight out to read all the controls. The buttons are black on a black faceplate and the printed labels, though white, are washed out and in about 8 point type. I wish designers would pay more attention to the ergonomics of electronics.

Great Basic Stereo Receiver Jan. 4 2009
By Kevin H. Cadarette - Published on
I got this for my parents for xmas, to replace their old Sansui that finally gave up the ghost. I hooked it up New Years day, and was amazed with the sound/power this unit puts out. I have a DE898 Sony stereo that cost about 2x last year, and with the same speakers does not sound anywhere near as clear or crisp. I tried both Polk monitor, and Bose InterAudio series and the results were the same; this receiver puts out plenty of power, and sounds very crisp. The highs are not tinny, and the base is not boomy, just very clear. Wow. Mom and Dad are very happy to listen to their reel to reel, cassette, cd, record player, and tv through the speakers, and hear detail they have not heard in years. I am wondering why I bought surround sound for me now, I forgot how good just plain stereo can sound. The remote is very easy to see, and understand. Nothing fancy, just basic.

There is some math issue here.
Onkyo says 50 watts per channel rms
Sony says 100 watts per channel rms
The Sony sounds like it is lower power, and has to be run at half volume to get much sound. Both units with the same speakers. I suspect Marketing departments are involved here, with marketing math.
