Reliability of Cary Audio Products

"This is useless data. The only valid data is generally collected by the manufacturers themselves or through some larger, high volume dealers."

Data generally speak for themselves. The sample may be problematic, but unless the respondents are lying, the data (plural, by the way) contain some information. For instance, if 24 respondents report reliability problems, then we are pretty sure that there were at least 24 defective units in the field. The problem comes when we try to extrapolate things like percentages to the population of units in the field. In the case at hand (BTW, the word you are searching for is "poll", which itself does not exactly apply in this case), the sample is biased to unknown extent, so that we can't place much confidence in statistics (like percentages) based on them. We have pretty high confidence that there are at least 24 defective units, and 15 working ones, but there is an awful lot of territory in between those two figures.

I like reading the reviews on Amazon. It is very interesting the varying opinions of a product. I have yet to see any product with a reasonable number of reviews have a perfect, 5 star rating. Some evaluations have to be discounted completely, of course, and I have warily purchased items with only a 3 star average rating but also with only a handful of reviews. I found the products to be just fine. People's idea of quality varies. Some people see quality as a product that works as advertised with solid dependability. Others perceive quality to be how an item looks, feels and performs. One person is happy with his $15k car because it starts everyday and gets them to work year in and year out. Another person is happy with their $65k car because it looks and feels good and the dealer treats them like a king every time they have to take it in for repairs. Go figure.

Coming late here....just found this topic by doing a search as I think I might be somehow unlucky.
I had one CDP from Cary that fail completely and after a few attempts at repairing it, they offered great deal on a better replacement unit so I took it and it has been flawless for the last 3 yrs.
Got SLP-03 recently, brand new....the headphone jack never worked. Will be sending for warranty repair soon.
Got 120S MKII recently and seems to have a problem...loud hum in left channel.

I totally disagree with the cary statement of not been reliable I own a CD3/300 and a cary SLP-98

and I have it for about 4 years I never never have any

issues with the two units.

I just upgrade the preamp from SLP-98 to the SLP-05

Maybe I expect too much, but I've owned a pile of both pro and hifi stuff over many years and am surprised at how reliable it has generally been, so if something goes bad I freak. I sent an Acurus A250 amp (new back then) back to Mondial 3 times for channel buzz therapy, and sold it sooner than later. Am I lucky? I research most things before buying, but I do now expect stuff to never break, which is unrealistic but seems to work for me. I will never buy anything hinting of unreliability so I'm trying not to bug about Cary as i'd like one of their amps someday...say in ain't so!
