I tried yet another set of speakers, some Paradigm Atoms that seemed to be sized well for the T2020. I also dragged out my AudioSource Model 2 so I could baseline the Atoms. Turns out the Atoms sound fine with the Kinter. So why didn't the Klipsch sound fine? I expect the two 6" woofers were just a bit much for the Kinter and the 12V factory supply and that's why the bass suffered. Also the tweeter in the Klipsch is way louder than the Atoms - I didn't not hear the switching noise as loudly with the Atoms but clearly heard it with the Klipsch. How does the T2020 compare with the AudioSource on the Atoms? It's probably 90% as good according to my tin ears. Bass was fine, treble was fine, nothing fuzzy or distorted sounding; totally acceptable for the price of the T2020. What about the switching noise? Well turns out I was probably hearing some inter-mods aliasing down in the audio range. With the volume all the way down and the audio input cable disconnected from the source you can see an 870KHz oscillation on the speaker outputs from the class D driver. I tried to get a scope shot of the aliased lower frequency noise but the best I could do was a 32KHz-ish scope shot. My hearing rolls off sharply above 13KHz but you can definitely hear idle "hiss" if your tweeters are any good. Is it a problem? Well I will leave that up to you to decide, as a studio monitor this is probably not your amp but to fill a room with sound, you will probably never hear the hiss. How well did it do with bass and high frequency? Well I did some scope shots to get you some data. These were taken in parallel with the speaker acting as a load and you can see the switching hash at high frequencies to be sure but you can't really perceive it. The 40Hz looks fine on the scope and the 20KHz looks a little hashy but hey - that's how class D works, not much you can do about it. I included some shots of the AudioSource so you can see the difference. The sine wave was from a function generator app on an iPhone for both amps. The AudioSource has the higher p-p voltages and the cleaner output obviously. What about the minimus 7s? Well they stink compared to the Paradigms of course but that's kinda apples and oranges. When I put the minimus 7s on the AudioSource they sounded similar to the Kinter so I began to suspect there was a speaker problem. The woofer surround looked fine when it was mounted in the speaker but when I removed the drivers I could see a crack at the base of the foam, which is why the bass suffered so badly in these units. So I put in some generic 4" woofers and the minimus 7s sound ok now on both the AudioSource and the Kinter. To be honest the Kinter sounded slightly better as you could boost the bass with the tone controls to match the tiny speakers. Bottom line - buy this amp if you have reasonable expectations and reasonable speakers, it sounds fine and it is worth the money. If you are pushing too big a driver you might be sad, but for a modest system the T2020 does just fine. Oh and this is not a paid review, I bought this thing. Also bought a DAMGOO bluetooth amp with the TPA3116D2 part in it. That amp sounds fine as well given the cost, same comment on the hiss, but no scope shots of it yet. ================= original review below =================== Wanted to like this amp based on the many reviews but they didn't deliver at all on sound quality. Initially I hooked it up to a pair of Minimus-7s figuring they should be well matched and used my iPod as the source. Started with the tone knobs both on mid range. The high end was super bright and clear but bass was muted. Fine, cut back on the treble knob and cranked up the bass and the amp delivered a fuzzy and muted thump for every bass drum kick. Ok - maybe the surrounds on these speakers are bad? Nope - the drivers had been replaced and the foam was all good. Ok maybe the crossover is bad, I'll try a different speaker. So I hooked up a known good Klipsch RC3 center channel speaker which has 6" woofers in it. Cranked the bass up again and it started to come through but still felt very thin. For something like a cello or standup bass notes you can probably get away with it, but for any music with a backbeat and some punch this amp falls flat on its face. Also there is a continuous 13KHz hiss coming out of the speakers, either with or without an audio source - regardless of volume level. Very noticeable, not acceptable. The final straw was when I plugged the iPod back into the Cambridge Soundworks model 88 radio I was trying to replace. Night and day difference, the model 88 has tons of bass punch compared to this amp, and my model 88 has had a long and hard life in the shop and has been rode hard and put away wet. It has a tiny 4" driver and it put our more bass than the alleged 20W into the RC3. If you own Klipsch speakers you know how loud they get and how efficient they are, it's kinda their "thing". If this amp can't drive a Klipsch, what the heck can it drive? Maybe I got a dud, or maybe all the hype was too good to be true, don't really care. Don't buy this amp unless you long for the sounds of a paper dash speaker with a whizzer cone in your clapped out Chevy II, and a photo flash unit charging up next to your head. Review: When I thought to myself the following night that perhaps having a second one might be fun for a blu tooth set up meant for listening ... - When I spotted this little amplifier on desertcart the other night (3/8/2018) there were 16 left. When I thought to myself the following night that perhaps having a second one might be fun for a blu tooth set up meant for listening while in the shower? They were completely gone already. I expected them to go fast, but damn! Ok, so I bought this to use for testing mostly. I have three pairs of Dayton Audio B652-Airs that I purchased a while back to use for the '5' in our 5.1 surround sound set up in our theater room. The B652-Airs get great reviews, sound especially good for their price, and are ones that have a good following among those who like to modify inexpensive speakers in order to get better performance from them. I wanted to do the same, so I needed an amp. This one has the infamous/extinct Tripath TA2020-020 amplifier chip, came in at a good price, and already had a few positive reviews... so home to me it came. Initial impression: It was packaged well with no excessive stuff inside. In the regular brown cardboard box with the company logo and slogan/motto on it? was a double-sided one page operating manual, a power supply with its wall plug, the amplifier, and some squishy foam to keep everything safe. No excess, but probably more than what I was expecting for the 30 bucks I paid including shipping. The amp: Its a nice, simple amp. Everything is clearly labeled and everything is sturdily mounted. Nothing on it wiggles or is loose. It is certainly well built from what can be learned from the outside. All the knobs are easy to turn AND get to, something that is not always easy to accomplish for a guy with large hands. The performance: Obviously an amplifier's performance is best measured with scientific equipment, none of which I have. An initial 30 minutes of listening had my ears telling me the audio sounded pleasant on pleasant sounding speakers, nothing sounded muted or stuffy or electric (think about cheap pocket radios and the audio that comes out of them to understand my use of the term "electric"). I found myself wanted to find time to keep listening and skip doing other things I needed to do because I was enjoying just listening to music. One thing I always check for is excessive 'hiss' when a speaker is hooked up to an amp that isn't playing anything or connected to an audio source. While there certainly is some with this amp as with most, it is nothing that is noticeable from more than a foot away or less with the amp turned to full volume. If you made it this far down? I realize I'm leaving a review on a limited edition amp that has already sold out and may never return. But if you are reading this and it becomes available again? And you're on the fence about making the purchase? Don't be. Just buy it. Its more than worth the 30 bucks, and you'll be happy that you did. 5 stars hands down. Also, I like to see photos in the reviews I read, so I've included a bunch for anyone who may be interested. I didn't take the time to measure the dimensions of the amp, but I've included a Pepsi can for size reference. Thanks for reading, hopefully this was helpful to someone out there. ## Features - ORIGINAL Tripath TA2020-020 amplifier chip provides efficient, powerful sound - LIMITED SUPPLY will impact pricing - Compact size makes this amplifier great for projects and DIY audio applications - 3.5mm Input, Gold Plated RCA Connectors and Improved Speaker Connectors for Superior Signal Conductivity - 12 Volt 5 Amp power supply included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077Z7DBRT | | Best Sellers Rank | #161,623 in Electronics ( See Top 100 in Electronics ) #1,030 in Audio Component Amplifiers | | Brand Name | Kinter | | Customer Reviews | 4.4 4.4 out of 5 stars (1,374) | | Item Dimensions | 4.72 x 5.79 x 1.65 inches | | Item Weight | 1 Pounds | | Manufacturer | Kinter | | Minimum Supply Voltage | 12 Volts | | Model | K2020A+ | | Mounting Type | Surface Mount | | Number of Channels | 2 | | Output Power | 20 Watts | | Specification Met | CE | | UPC | 651814994414 | | Voltage | 12 Volts | | Warranty Description | 1 Year Warranty | ## Product Details - **Item dimensions L x W x H:** 4.72 x 5.79 x 1.65 inches - **Manufacturer:** Kinter - **Minimum Supply Voltage:** 12 Volts - **Mounting Type:** Surface Mount - **Voltage:** 12 Volts ## Images ![TRIPATH K2020-020 - Image 1](https://m.media-amazon.com/images/I/71+0JAFy1-L.jpg) ![TRIPATH K2020-020 - Image 2](https://m.media-amazon.com/images/I/71Dr1+mdg4L.jpg) ![TRIPATH K2020-020 - Image 3](https://m.media-amazon.com/images/I/814W-edDrOL.jpg) ![TRIPATH K2020-020 - Image 4](https://m.media-amazon.com/images/I/71DkQBceN9L.jpg) ![TRIPATH K2020-020 - Image 5](https://m.media-amazon.com/images/I/71vAzosvfML.jpg) ## Questions & Answers **Q: How to use this for karaoke?** A: No. Buy a karaoke machine that’s what you use for karaoke. **Q: What is the acceptable dc offset for this amp? the one amazon just sent me has 17mv on left channel and 72mv on right. on a class a that's too much!** A: At your DC offset values you are still in the spec of max offset voltage of Tripath TA2020-020, which is 150mV. (you can google for a spec sheet) Your amplifier is fine and should play nicely. ( My own personal K2020A+ has 15 and 102mV DC offsets.) That being said, there is more to say about DC offsets: The K2020A+ utilizes the standard Tripath circuit board design. There have been many mods developed over the years that have improved on the original design, If you are adventurous, you can google these 2020 mods, and also especially search on diyaudio forum online, you will see some mods address the common variance in DC offsets that yours has, but again, your amplifier is fine and within the Tripath Specs. Note: Obviously modding the amplifier will void the manufacturer's warranty. **Q: Is it just mine or does the power supply not seem to plug in all the way , it works but it’s sloppy** A: Mine didn't plug up either, I was going to replace. I notice its not 12V 5A. Its 125V I hope it didn't blow it up. I put Netgear 12V5A. & lite came on. **Q: Use with 16 ohm speakers?** A: If it will power 8ohm it will power 16 ohm speakers. Just won't be as loud. I own one powering a pair of 8 ohm bostons. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Update: Worth the money, decent amp, just buy it already - it's 10 cups of coffee *by A***L on November 25, 2020* Update - the amp performance still bothered me, too many positive reviews here so I did more testing.
