Strength:

My ear says that this amp has a beautiful sound. These things being pretty subjective I still would say that this unit sounds a little mellower than some past solid state amps. Digital controls now allow for seperate settings for each input. I give this a high recommendation except for one small but irritating design flaw. See below. Lakewood Bounce House Rental

Weakness:

None , . .

Strength:

I've got these matched with a Pionneer Receiver pushing 100 watts per channel. They sound clear and surprisingly push a decent amount of bass for smaller speakers. Have a little time to look at: Artisan Couvreur Strasbourg

Weakness:

cant say there is any

Strength:

I think that receivers/amps/tuners/etc from the 70's are easily the best looking pieces of home audio equipment ever made. I personally like the pioneer silver series the best with the marantz a very close second. - exterior wash

Strength:

Well built, great headroom, classic styling, very musical. I bought this new in 1976, It's been driving a pair of Dynaco A25's all these years. I bought the speakers in late 1974. It's a great match up of components. It has become my bedroom stereo. It still works/sounds great after all these years.

Weakness:

I did need to get it serviced about 30 years ago. The power on delay relay was malfunctioning but other than that no problems whatsoever. The guy that serviced it back then said that anything of comparable quality would easily be over a thousand and it was definitely worth keeping.

I got the vintage "bug" years ago and I have since collected a great number of vintage receivers and speakers. The Pioneer SX850 is one of my favorites. I am using it with a pair of B&W DM 220 monitors (mid 80s) in my office and the sound is simply great. I was lucky to find the received locally and the old couple that was selling it had put very little use on it. A burned bulb easily replaceable (with some patience), some cleaning with De-Oxit and this was it. I seem to enjoy the sound of vinage gear a lot, especailyl when I get in one of my nostalgic moods. They seem to make 70's music sound...at home!
The feel of this uint is really exquisite. It glows "quality". The sound is relatively smooth, the bass strong and the highs clean. It competes well with my other favorite mid/low powered receiver the marant 2252B although the Marantz beats the Pioneer in the "musicality" department.

As I said' these are great units to enjoy on a regular basis and w/o a critical ear. They sound great BUT can never compete with well made modern gear. I have the Sansui 9090DB, the Pioneer 1280, the Marantz 2325 (my favorite by far from all the vintage gear at home) and I enjoy them all in my 4 vintage systems around the house.

However, and just to put the record straight: NONE of these receivers can hold a candle to my audiophile system in the living room. NONE! (Musical Fidelity KW 500 amp, Sota Cosmos TT, Engleston Andras II sepakers etc).

Despite silly claims that "they do not make them as they used to" ...THEY ACTUALLY do...and MUCH much better! Advances in semiconductors, circuit topologies, manufacturing techniques, material science etc. makes well made modern gear WAY better than vintage stuff. The problem with some people is that they;

1. Have NEVER listened to a serious modern system (even a mid priced one)
2. Compare a 20 year old Mercedes (ie great vintage gear) with a modern Yugo (ie Best Buy plasticky crap). The comparison is not fair. My marantz 2325 was costing close to 1000 back in its days. It would cost close to 3000 or more today.
3. Cannot afford anything serious and they just dimsiss what they cannot afford as hogwash. (Yeah, I cannot afford a Porche Cayene so I believe it is not any better than my Honda Pilot).

Again, the Pioneer SX 850 is a superb receiver that if purchased in good condition will give great pelasure to its owner. pair it with good speakers and it will sing for you. There are better alternatives at similar prices (Marantz 2252B) but it does hold its own...

Enjoy the music

My SX-850 is in mint condition, perfectly clean inside and out, not a single scratch and 100% original. I paid $150 for it from an estate sale and they were the original owners and I swear they kept it covered and never used it because I don't know how something this old could still be so pristine. I always keep mine covered with a microfiber towel when I am not using it because I WILL pass this on to my children when i die and I want it to remain as beautiful as it is today.

I think that receivers/amps/tuners/etc from the 70's are easily the best looking pieces of home audio equipment ever made. I personally like the pioneer silver series the best with the marantz a very close second. It blows me away how much detail and quality went into their entire construction and not just the outside but even the insides are a work of art. If you ever look inside one you will know what real quality is and whats crazy is the inside was really never meant to be seen.

As for the sound, they are simply amazing. I have listened to a lot of different receivers and amplifiers of varying price points and build quality and none have come close to the sound quality of my SX-850. Whats always funny to me is most "black box" gear claims 100-120 watts/ch, but this 85 watts destroys them in clarity, musicality, sound stage, and DB levels to boot. I will admit I have never listened to the crazy audiophile gear that costs many thousands of dollars, but I can't imagine how they could sound that much better than this. As many have said music if very neutral, but still very lively and engaging. I have used both pardigm 3semkIII, and home built Ero's by Wayne J. at speakerbuilder.net and I will sit and listen for hours and just want more no matter what I play.

The integrated tuner is another beast that lends to the quality of these machines. Not only do they pick up even the weakest stations, but you will be amazed at how good FM stereo sound quality can actually be. I think this is easily what has impressed me the most. This makes me really enjoy listening to all types of FM stations, but I have really come to enjoy listening to classical stations because it really does sound better on my SX-850.

Finally I must suggest that everyone get a power filter. I recently picked up a Panamax 1500 and after plugging my SX-850 into it and listening for 15 minute I was sold. The background is more quiet and the sound seems to be more dynamic and clear. Not to mention it is a lot healthier and more safe for all you home audio/theater equipment so it is worth the investment.

The only negatives I can say are the obvious....no remote control, it has push terminals for the speakers, you don't get the conveniences of digital tuners like presets (but how can you not love the feel of turning that dial?...so smooth!!), and I wish it had midrange tone control.

Just buy one if you have ever thought about it. You will never regret it. Like everyone has said...THEY WILL NEVER MAKE THEM LIKE THIS AGAIN. You are buying an investment in quality, craftsmanship, engineering and pure enjoyment
