TRY and find a better amp for the $$$$$$, you can't...
21 October 2012
Summary: I have this amp powering a set of $5000.00 Focal Electra 1027S tower speakers and it sounds unbelievable. The price/speaker is relevant in this review because a speaker of this caliber reveals any and EVERY detail in the sound fed to them. The phono preamp is not bad, and it didn't sound too much different then the $200/$300 phono preamps that i have heard. Anyone using a moving magnet cartridge not wanting to buy a separate preamp will be extremely happy.
Summary: I have had this amp since it came out and am very happy with it.I do not notice any high or low frequency problems,it is clean and accurate across all frequencies.No hum,no distortion just great music.I listen to classical and jazz,my system is decidedly mid-fi,besides the onkyo 9555 I have a onkyo 7555 cd player a rega rp1 turntable that are played thru dynaudio audience 52 speakers.I think the vast majority of music lovers will like this unit.I do.
Summary: We purchased this to replace a 20+ year old Yamaha Natural Sound receiver and amp that was showing signs of its age. We no longer need a receiver since we stream our music, so thought this amp would be a nice upgrade. What a disappointment!!!! We have a couple of Klipsch Chorus ii in the living room, and this amp did NOT provide decent sound. It was muddy, the highs were gone, and the bass? Who knows where it went.
Summary: Looking to replace a 10 year old Arcam alpha 8 amplifier, i had requirements of a phono input, and less than five hundred bucks. Well after hooking it up, I played all my sources through it it sounded great. However the clicking sound that occurred when switching on and off did not fill me with confidence. Lo and behold, after only 3 days use, it would not power on after being in standby mode.
Summary: I was looking for an affordable Integrated Amplifier that was dedicated for Audio playback only for my modest home audio system. Most home audio gear nowadays is geared towards supplying the Audio/Video sector of the market with cheap Receivers flooding the market. I wanted something that moved away from that genre yet contained the quality and performance of a near-Hi-Fi system that I wanted but could not really afford.
Summary: I purchased this amplifier with the Onkyo CD player DX7555 Audiophile Single Disc CD Player. They made beautiful music together but the A-9555 amplifier just died about 14 months after my purchase. I then discovered how difficult it is too get any service on an Onkyo product. I cannot recommend any Onkyo hifi product based on my experience.
Summary: My old 80's home stereo was having some problems and I assumed it was the 1980's Onkyo A-8700 amp. Long story short I bought this A-9555 to replace it. Its a good amp and sounds pretty good. It is lacking in inputs, but will safice for your basic needs. This amp is 85 watts per channel at .08% total harmaonic distortion. Distortion means when you crank up the volume you get fuzzy or dirty sound.
Summary: After a break in period the amplifier sounds fine through my Infinity Primus P162 speakers. Very nice range when kept in the speakers limits, when pushed the sound gets compressed and harsh--but I am thinking its the speakers and not the amp. The phono section seems to be good, I need a new cartridge to be able to judge accurately.
Summary: I bought this amp because my Onkyo Integra finally died. The Onkyo A-9555 was delivered DOA. As with another reviewer, all of the monitoring lights were on and the remote had no effect. Onkyo customer service described this as being in the "safe" mode. Onkyo customer service was polite and responsive, although it took awhile to get through. They suggested that as it was delivered DOA, I should return it to the dealer (B&H); I did.
