New Tool for Quick Amplifier Comparisons. Looking for Your Input

[freddysampayo]

Hey ASR folks! Been absorbing your collective wisdom for years, figured it was time to contribute something back.
After spending two decades in the AV industry (and probably losing some hearing along the way from testing one too many line arrays), I thought it was time to finally join the conversation.

I've been in the trenches installing everything from modest stereo amps to beast-mode stadium systems (1500+ installs and counting). After countless CEDIA and AVIXA shows and endless hours comparing specs, I noticed we all face the same challenge: there's no quick way to compare amplifier specs and prices without opening 47 browser tabs and developing carpal tunnel syndrome.

So, I decided to do something about it. I've created amplifierprices.com, a straightforward comparison tool that lets you quickly browse and filter hundreds of amplifiers based on their key specs: power output (advertised and tested), THD, SNR, special features, prices, etc.


What makes it different is that everything's consolidated in one place, so you can say goodbye to tab juggling. The platform focuses on the specs that matter most, with simple filtering to narrow down options for your specific project needs, no reviews or trying to convince you what's better. I've already included hundreds of models, and the database keeps growing.

I want to make this truly useful for our community. I'd love to hear which brands you'd like to see added, what specs or features should be included in the comparison, and any suggestions to make this more useful for your workflow.

This is just the beginning, and I'll keep expanding the database. Consider this an open beta, your feedback will help shape it into something we can all use.

Check it out and let me know what you think.

Looking forward to your thoughts!

Hey Freddy, welcome to ASR.

Check it out and let me know what you think.

Looks helpful, can't hurt and as you say much info in one place.

Here is a list of class D amps that I started and is in progress.

ASR list of known class D home audio amplifiers.

Any suggestions are welcome. Post suggestions here. I will gather the details and add them. Thanks. :D This will be organized as results come in. So give me brand names and model numbers of class D amps and I'll create the list just like the EQ/PEQ webpage @ ASR is done. 3E Audio 260-2-29A PFFB...

That’s an excellent idea you’ve come up with!

Proposing the addition of:

• Form factor (rack-mounts, feet, full-size residential, 43 cm, etc.)
• Dimensions
• Weight
• Cooling solution (passive/active)

Thank you for the feedback! It's interesting you mention dimensions and weight. I initially considered including these in the database but decided against it as I rarely found them to be primary decision factors in my specification process. Has this been a crucial factor in your workflow when specifying amplifiers? I'd be curious to hear your perspective on this.

Hi Freddy,

We have a Global reach. While we ASR are a U.S. run site. We have a very large population of people from Europe and Asia. One of the first questions when someone is looking for new kit. Like an Amp. Is it available in the UK, or Turkey or Indonesia and Singapore. If this is something that is possible for you. Consider adding a “Available in Region” flag/sort.

Welcome Aboard @freddysampayo .

 

[Petrushka]

Page is not loading on my iPad.

Update: it seems to work with Safari, which is not my usual browser.

I’m a little put off by the amp power ratings, and the resulting price per watt.

First thing I noticed is the Wiim amp Pro costs ten times as much as the Fosi V3. I doubt if that is realistic. I doubt if the cheap class D amp power specs are real.

Same here. It doesn’t work with iOS. Maybe a PC focused version and an iOS version will come later.

Thanks i noticed that it takes a lot of time loading on google chrome on iOS. The page only shows when all the data is loaded into memory. I'll take a look at how to load data in parts

Sure, this is something I have planned.

Hi Freddy

Yes, I can see how the dimensions could be helpful for those who already have a rack or components and want to ensure the new amplifier fits properly.
As for weight, it’s likely less important.

 

[scorlee]

Yes, this is a good idea, although some parameters look inaccurate. It is recommended to set up a "Contact me" module, maybe someone will contact you to revise the parameter, which will make it look more authoritative

 

[somebodyelse]

Nice work so far.

The 'App' part needs a lot more granularity to be useful, such as:

1. which operating systems are supported by the manufacturer? Windows / Mac / linux / iOS / Android / web browser / other?
2. is the app in mainstream app store or does it require sideloading?
3. is the API open / documented / reverse engineered?
4. is there 3rd party support (Home Assistant, FHEM, GadgetBridge etc.)

An open or reverse engineered API means it may still be workable after the manufacturer abandons it, goes broke or whatever. And that a 3rd party could write an app for an OS the manufacturer doesn't support.

DSP also has a lot of subsets - PEQ or GEQ, number and type of filters supported, whether you can store multiple presets, whether an app is required to set them, whether they can be configured for individual inputs and/or outputs, and probably more I've missed.

Excellent work and worthwhile project.

Some criticisms (ignore my tone; I'm actually a more reasonable guy than it might seem):

• Why link to temporary Amazon listings, some of which are expired or unavailable? A link to the manufacturer's page makes the most sense. Or don't worry about links at all. Unless this is a monetization strategy, in which case I can't blame you, but I still find it irritating and reductive.
• Stereo vs. multichannel in use case and then a channel count section are redundant.
• The THD Range section is ridiculous and misleading. THD changes depending on the input level, output level and gain.
  • "Pro Tip: Don’t rely solely on power. If you want high-quality audio, look for THD under 0.05%.". Also misleading for the same reasons. Audibility of amplifier distortion is dwarfed by speaker distortion. A more in-depth explanation including gain staging would make sense.
• Actual Watts vs. measured Watts... A lot of this stuff is highly suspect unless you get a graph. I'm not sure how to handle this. There are standards, but they aren't often followed. Probably the best approach is to clarify that the number is only a spec and list the conditions for it. The "measured" numbers should reflect independent, verified third-party work or clearly signposted, reliable manufacturer work. Right now it seems like you are copying the same speced value into two columns in a lot of cases.
• "SNR: Signal-to-Noise Ratio in dB - measures background noise level (higher is better, > 90dB is excellent)" This is not the right definition. SNR is a ratio. It is not a measurement of absolute noise levels. Here's a good reference: https://www.ranecommercial.com/legacy/note145.html
• "Min (Ω): Minimum speaker impedance the amplifier can handle." This is also misleading (but it is the manufacturers' fault for creating this convention, especially when it comes to selection switches). Take the AtlasIED AA35G, which has been speced at 8ohms. They have this note:
  

Please go beyond treating it only as a buyer's guide. Just by gathering all of these sources, it also becomes a historical project, especially if you end up keeping this going for more than a few years. I think one of the best models to follow is @pierre's for spinorama.org. People use it because he put a lot of effort into making the data comparable across speakers and linking sources. I explore it all the time for that reason, link to it a lot during discussions, and contribute new data the best I can. I'm sure it generates sales indirectly. If you turn "amplifierprices.com" into a place where people feel like they are learning, they will use and hype the tool, you'll get that referral link revenue, too.
