flabbergasted with reviews on speakers

@jerryg123 - Merry Christmas to you, too!! 

Nope, not calling it a lie, it’s just a bloated bit of horse apples, like most reviewers.

they will up their selected words for a review. For the companies in their rag, and financial supporters.

if you wanna call it a lie, then so be it. They do elevate most reviews to make the reviewed products seem better. This has always been the way of the reviewers (most).

 They will not bad mouth paid advertisers, or they will lose those huge checks, and these select reviewers, know how to butter up companies. 
rarely have I read a review which dumped on the product  

Electrolytic capacitors are not "bad" in and of themselves. It’s just that over time, *some* of them, especially in a hot environment, will begin to dry out and change value. How long? Usually, 5 to 10 years or MORE. If you are willing to rebuild your crossover every 10 to 15 years, (or at least use a meter to check values), then they should be no problem.

As far as the YouTuber speaker reviews go, I think most of them try to be honest in their assessment of a speaker’s sound. And after watching enough of their reviews you can begin to figure out what kind of speaker THEY find appealing.

That might be very different from what YOU find appealing, but you can sort of read between the lines or "triangulate" and "extrapolate" what they are saying.

For instance Christy on Andrew Robinson’s channel and the old Audiophiliac Steve Gutenberg both prefer "lively" even "bright" speakers...i.e. Klipsch and Focal and some models of B&W.

At least I know that when I hear their reviews.

But yes, the trend these days toward reviewers mainly concentrating on smallish bookshelf speakers isn’t helping me find out what I want for the living room.

Having owned some old AR-9 speakers that I adored; I can’t see being content with "small" sound. Where are the reviews of floor standers and towers in the $1000 to $3500 range each? That is within the realm of my amount of interest.

Then you have the issue of reviewers never telling you how speakers sound at various volume levels. For some people, speakers need to sound good at lower volumes as much as when rocking out.

Some reviewers also won’t do negative reviews. Like Steve G, he’d rather NOT review a product than put out one trashing a speaker. In the $1000 speaker category this year most were fawning all over the KLH Model 5, but Steve decided to not do a review on them saying he just didn’t hear what all the other reviewers heard. YMMV, etc.

I guess at the end of the day, watching YouTube reviews of speakers is like watching people in a restaurant trying to tell you how a food tastes. Better than not watching one at all, but definitely not like trying said food for yourself.

Are speaker sensitivity real or is it to sell more expensive amps.

It depends on the integrity of the speaker company. See the reviews below.
