I bought the TX-SV535 a long time ago, and I am very satisfied with it. The volume this baby can deliver! Man you shouldn't think that it only delivers 3x65 and 2x25 watts. For Prologic this i very good, and for stereo it also sounds good.
However it can't be upgraded to Digital surround, so I have just bought the TX-DS676. I am sorry that I have to get rid of the 535 because it have never disapointed me (well of course there was the time where it wouldn't play. Tape monitors can be a pain in the *ss).

If you don't need Digital surround my rating is 5 stars.

Good power, and sound capability from a pro logic reciever. So far 2 years and counting with no problems whatsoever!!I have a whole Klpsch surround speaker system it sounds wonderfull, good power excellent sound.
Id recomend this digitaless unit if you can not afford digital!!

It still works. Good short circuit protection circuitry for when you accidently short speaker wires.

Muddy, distorted sound, rolled off high end, can't push enough current.

I have had this unit for over three years now, I guess. I had a really good mid-1980s Pioneer with power supply components in it that would cost you at least $2000 to get in an amplifier and is now nonexistent in a receiver. Then it died of old age after about twelve years, the capacitors give out you know, the electrolyte breaks down. So I went through some NAD and Adcom separates try to equal the performance of the Pioneer but they really were not quite as good in spite of the marketing departments lies. This Onkyo is solid mid-fi, slightly better than a clock radio.

Did I mention that I am electrical engineer? You see, how things work is that we are ordered to design things to maximize profits, not to make the best products. Nobody does that. It is up to each company's marketing department to invent some pseudo-science babble to convince you that they are all trying to make the best product and, of course, their company's product is the best. But company's are not in the business to make a good product, they are in the business to maximize profits by selling a good story and bestowing the purchaser with some snob appeal and a story that he can ape to his friends to look like he's an electronics genuis who really knows what he is talking about. Don't believe me? Don't like the sad truth? Read Dilbert, he's another disillusioned EE like me who went into the business for the humanitarian reasons of improving the average guys quality of life by continuing to make things better and cheaper every year. I have already been receiving vulgar threatening email from this board calling me every four-letter word an adolescent can think of for telling this and other truths about how to tell the good equipment from the bad because this board is only for advertising. They want all five reviews. They want you to take technical advice from some guy whose review is "this baby rocks" or "kicks @$$" or "awsum" or some such boring infantile macho-wannabe tripe. They don't want an educated buying public. They want you to believe whatever you are told and to remain ignorant about the facts of good amplifier design and manufacture. This is also my second post of a review of this product that I have owned for over three years because the board removed the first one in less than two days.
