So far, this amplifier has exceeded my expectations. I was using an AV receiver to drive Monitor Audio RS6s with the RSLCR and RSFX surround speakers, which is beyond my expectations. This amp not only pushes these speakers more aggressively but also has a quieter background and much better midrange and high frequencies. I've had a few top-quality amps over the years, including an Aragon 4004 and a Jolida 1501rc, and this amp sounds better. Don't be fooled by the power rating of 85w per channel; this is an honest rating of 85w x 5 for all channels driven simultaneously, putting it squarely in the range of 140w x 5 or 7 AV receivers usually rated their power in watts.

Sweet, Clear, Rich & Beefy sound at all volumes. Non-fatiguing high volume sound. Exceptional Value: < $100 per channel for sound that will make you lament waiting so long to move up to high quality amplification.

If your speakers are inefficient (<93db1watt/1meter), consider the 855A's big brother, the 1205A, and then ONLY if you like to shake loose the nails holding your house together on a regular basis.

I picked up this unit on ebay for 426 including shipping. I waited a couple weeks of listening prior to this post. I agree with much of what has been posted by the folks before me. I am running a Denon 3803 as a preamp/processor and was slightly concerned dropping from the Denon's rated 110 watts per channel to the Parasound's 85 watts. I've verified what I had suspected: The power rating is largely moot. I could crank up the Denon to levels I could barely stand to be in the room, but the smooth high end of the Parasound makes listening at high volume a joy; volumes where the Denon was terribly fatiguing. This may not be a high fidelity amp by audiophile standards, about which I could care less. I notice the clean sound, the smoothness and richness of music. High end, Midrange and Bass are all noticibly better than the Denon. I'm not an expert on "vertical and horizontal" soundstage, but I know great sounding audio reproduction when I hear it. To the point: If you have some excellent speakers and a receiver you paid less than a grand for - maybe even 2 grand - you will HEAR an AMAZING difference if you pick up a really good power amplifier - and make no mistake, this "little" 85 watt per channel amplifier is a GREAT amplifier. I would suggest that, if you listen often at HIGH concert level volumes AND have inefficient speakers, you may want to see if you can find a HCA 1205A. It'll likely cost twice as much used so think hard about it. I find this amp is a perfect match for my Klipsch speaker system, which is very efficient at around 98dB @ 1watt/1meter. The Klipsches are very bright by nature, so the smoothness of the Parasound high end allows me to run my bass and treble setting flat compared to the Denon, which I was running at -4db treble and +2db bass. But I've learned settings are not the answer, they're just a tweak, and have little bearing on the depth and richness, the "soul" of your system's sound: Upstream from the speakers, that soul is largely in the character of the amplification, and the Parasound has great character - arguably unbeatable for the money. Conclusions? I'd gladly trade several hundred watts of amplification with the (pretty darn good) characteristics of my Denon receiver for the sweet midrange, clear subtle highs and beefy bass I'm getting from 85 watts of Parasound. There's just no contest. BTW, if you have a Denon receiver with a 12V trigger, it takes a 1/8" mono mini jack (phone plug) available at radio shack. It's nowhere in the Denon manual (which is abysmal). The center connection is the 12V trigger signal and the outer sheath crimp/connector is GND. One last thing - if you want phenominal power (for almost any efficiency speaker) and sound from your fronts, you might consider consider bi-amping them with one of these puppies, if you can find one: you may end up with more net power for less $ than buying a higher power Parasound amp, which tend to go for more coin.

IAm posting this review to state that my previous rating is incorrect. This product rocks, and it it deserves the best quality rating that any audiofile wannabe's want to hear and read. My sound system is incredble to listen to since adding this key piece of power to my home theater set up. The bass will stir up yesterdays lunch, the treble will tickle your ears without harshness and the midrange will blow you away. This is a superior power amplifier that will make your system sound powerfull. I A'm currently running A Denon AVR2800 reciever- -Parasound HCA-885A high current amplifier -Paradigm 11SE Fronts -Paradigm LCR350 center -Paradigm Mini monitors for rears -Paradigm PS1000 Subwoofer I want to upgrade to a Denon Avr3800 but that will take some time and cash and possibly the turfing of my old lady.

This amplifier really kicks major ass. I'm currently running a Denon AVR2800 reciever that at first I was very happy with. But over a period of time it seemed to lack the midrange and definition that I wanted. I tweaked my system by adding a Monster HTS2500 power conditioner and that improved the sound. I BI-Wired my Paradigm speakers and that improved it even more. I built speaker (sand filled and on spikes) stands and that tightened the bass right up. I positioned the speakers according to the manufacturers specs and that made a difference. But my ears were not satisfied. I bought the best sheilded cables that I could afford and that improved it even more, but it still wasn't right. I was stumped at what else I could do that would not cost a fortune to appease my selective hearing. I was in a quandry as to what other recourse to take. After many months of searching on the net and inquiries at my local Denon dealer I was introduced to a Parasound Amplifier that was touted to be the best for my current system. I had read reveiws on this site that the Parasound amplifiers were the best bang for your dollar. My Denon dealer offered the HCA-855A to me at $1000.00 Canadian taxes in. But Troy, the owner said that I could take the unit home and try it out first before I bought it. Well I have to say that unit is now a major part of my set up. This amplifier has completed my lust(I think)for excellent sound. I still have a slant towards the denon AVR3803, and that will probably happen. The parasound amplifier is absolutely the best thing that I ever could have added. The bass is tightenend right up to a point that it sets you back in your chair. The detail and midrange is astounding. I'm hearing things that I had never heard before on DVD"S that I have played before. This Amplifier is the sweetest thing that I ever could have purchased. The sound is so amazing that it has truly put my home theater into a class of it's own. The fact that it is 85 watts all channels driven is truly remarkable. Parasound has has a true edge over high end and much more expensive amplifiers.

My room is not huge, my speakers are quite efficient, and my listening habits do not include ear bleeding levels. I use an amplified sub for the deep bass. What I am getting at is that this "85 X 5" amp has ALL the power I need! I have never pushed it beyond its limits, and we listen to our movies loud. I know for a fact that "85 X 5" Parasound power in this amp will blow away Receivers that claim "140 X 5" power ratings. Detail is fantastic. Bass is powerful and well controlled, and strain at high listening levels is non-existant. I am very happy with this amp!

Detail, Detail, and more DETAIL wider soundstage midrange is tremendous (especially with female vocals) great LOW VOLUME sound too never sounds strained best sounding amp I have owned

runs a touch hot weighs 41lbs do not know yet any more

All I can say is "why didn't i get one SOONER"? I have BIAMPed two Snell E-5 speakers with 4 of the 5 channels (much the way previous post did ..ASTROL). I am running through a DENON avr-4800 as a pre-pro. This is by far the cleanest and best sound I have had in my humble mid-fi (hi-fi) setup. Wonderful headroom, great seperation and better clarity (especially with dialogue in movies) than DENON amp. I worried about the load on the AMP, running 4ohm speakers,but I will have to keep my eye on the it. For now it just sounds exquisite. I will be PARASOUND fan now for a long time.

After reading everyone's review about the possible lack of power, I was a bit worried about possibly having made a bad choice. I'm here to tell you it was a great choice!...but you need to be particular about the speakers you choose. The speakers need to be very sensative (at least 88db). If you can find speakers that have their base managed through an internal amp or some good, quality book shelf monitors (Klipsch, M&K or DT) you will do yourself a favor. The amp is not powerful enough to drive thirsty speakers that are full range and have no ampliphied bass. I have some infinity preludes that are very sensative (94db) and the floor standing prulude's bass is powered by a 250watt internal subwoofer amp. They sound great. Lots of detail, depth and plenty of power to drive highs and mids. I also hooked the up to Infinity RS 4b fullrange towers with two 8" woofers and they didn't sound nearly as good. Choose your speakers carefully!

Highly detailed, yet smooth sounding. Excellent soundstage.

"only" 80 watts/ channel.

Replaced Denon receiver in 5 channel DVD-Audio system. Using with wide range(25-30khz)speakers. Incredible detail, soundstage. More powerful than 80watt rating suggests. Surpasses some high-end gear costing 3times as much. Highly recommended.
