Honest Amp Reviews: Impossible?


So, I’ve noticed a flood of class D junk hitting the market over the last several years. They come from many different brand names from people you’ve never heard of before like "VTV", to popular Internet-in-the-know brands like PS Audio to famous names like Marantz. One thing they ALL have in common: the complete inability to find honest reviews online for these products.

For example, let’s take for instance the Stellar series from PS Audio. Class D junk with the usual attempt to improve euphonics with some kind of input stage. They call this scheme class AD, I guess to differentiate all the other brands that do something similar. However, you’ll never see a review site point this out; they’ll comment briefly on the design and then dutifully call it class AD afterwards as if it isn’t just a class D amp like many others.

Next, the reviewer will invariably lie about the sound. This lying usually takes the form of lying by omission. They’ll gush about how beefy and controlled it is, how neutral it is, how wide and natural the soundstage is, etc. What they WON’T mention is how lifeless, flat, boring and ultimately fatiguing they ALL are. The buyer who doesn’t know any better has to find that out for themselves while he slowly grows to distrust anything a reviewer has to say about anything. So, the only way to actually get value out of a review is to see if a certain amp has the positive attributes you are looking for while trying to painstakingly research any problems it might have because the reviewer won’t mention them.

In addition to the lies of omission, there’s the usual con of giving certain gear to certain reviewers who will appreciate / like the piece. That Stellar will NEVER be put up against a Dan D’agostino or a Pass for example. This could be valuable to the buyer to see how a lesser amp stacks up against a high end one, but it’s not, apparently, useful to the reviewers. Why? Why is telling the whole truth about amps -- all gear really -- taboo?

@yyzsantabarbara Wow this reviewer actually tells the truth about class D (his review of the Keces S300):
If you are currently using a class-D amplifier and enjoy the hell out of it, then please stop here and go read some of my latest DAC reviews. If you are new to this or if you are curious about the best sounding amplifier topologies, then please carry on.
Ouch! Truth status: told. I think I'll pay attention to this guy.


Hmm, very interesting. I have Fostex TH900 modded for a balanced cable. I wonder how well these cheap units stack up to my Mjolnir 2 with NOS tubes. I think I'll read what this guy has to say...
Alright. For the class D believers please describe your systems. I bet not one of you has anything approaching high-end and you've all been successfully marketed to by the "affordable" audiophile scam. I also bet that none of you have ever compared your class D to a good linear amp on a long term basis, you just got wow'd immediately by the tight bass and high resolution and are in the throes of desperately pretending you like the sound even though you find yourself not listening to it much anymore.
It’s not a matter of whether I agree with a review or not. The problem is that the reviews aren’t honest. For example, go to any hi-fi review site. You can always tell if a piece of gear is good at imaging or not if the reviewer mentions it. If the reviewer praises imaging it’s probably good at imaging but if he doesn’t mention imaging at all it’s probably bad at it. This is lying by omission and a tactic which seems heavily deployed against low-budget audiophiles.

Furthermore, I constantly see this phenomena of budget audiophiles becoming emotionally attached to budget gear, as if they found an amazing value club allowing them hang out with the big-dollar crowd. In reality they’ve just been marketed to successfully by cost-cutting manufacturers. This marketing scam is facilitated by the review sites which do nothing but feed into peoples’ confirmation bias. The reviewers should be telling these buyers what they are actually getting into honestly. No, there isn’t a free lunch club. There are some legitimate better-than-standard value manufacturers out there but they get swamped by the cost-cut marketing scheme, and these reviewers are complicit in this.

For example, take PS Audio. They make great gear. But they also market class D junk to budget-minded audiophiles. You will search in vain for any review which points out the drawbacks of class D, and often you’ll see lying about how PS Audio defeated those problems if mentioned at all.
Yes that is exactly the sort of lying by omission and also being breathlessly positive over everything being reviewed which makes professional reviews useless. We shouldn't HAVE to read between the lines and pick apart what's not being said.

How did I develop this hatred of class D? I didn't start out that way. I developed that outlook after numerous failed experiments. There was always an excuse, always someone breathlessly extolling THIS amp was the greatest, THIS one is the real deal, THIS one will change your mind about the topology, etc. All LIES. It would have been GREAT if the reviewers had taken on the burden of explaining the serious limitations of class D and how even the best ones will be fatiguing long-term, that way I could have limited my pain being sent down wrong paths for so long. I had to learn the hard way that I'm NOT the target market for cheap cost-cut crap sold at a massive markup to people who were led to believe that they found the secret super value club when in fact were just suckered into a class D scam.

It would be GREAT if reviewers could lead off a class D review with "As my readers know, class D amps are garbage for these reasons. Today we're looking at X amp to see if it can overcome the faults of the topology has been struggling with for decades." If the manufacturers don't like having their products lumped in with "garbage", then they should consider not releasing garbage.
My new favorite reviewer is Soundnews.com from Hungary (headphone related).
