It appears that the class-T amplifier chips from Tripath are no longer being made and all the other mini amps out there have migrated to the "lesser" TI (Texas Instruments) chips. While searching around I happen to see someone recommend this Kinter limited edition amplifier as the only one still using the Tripath chips, so I jumped on the chance to own one. The amp comes securely packaged, and includes a good quality power brick in the box. Not included / what you need to add is a pair of speakers, speaker wire, a 3.5mm or RCA cable, and a sound source. My source is a desktop PC, so the 3.5mm audio jack was a nice surprise as I expected I would need to hunt around for an RCA adapter! I made all the connections and powered it on - you will hear a "click" from the speakers when turning on and off. I have connected a pair of Polk bookshelf speakers. The sound quality is great! With using the "direct" setting on the AMP I find the sound warm and full. There is perhaps a bit too much mid-bass by default, but I believe this is the tuning of the speakers more than the amp. Both stereo channels are working great, and the power produced is more than enough. I keep the amp volume knob at 20% and use the PC volume slider to adjust up/down as needed. One thing I like is the amp does not require a threshold to start playing, so even at extremely low volumes the speakers continue playing as expected. Bottom line: Discrete amp provides more flexibility, upgradability, and better overall sound than a comparable set of powered PC speakers at a similar cost. Pros: Hi quality Tripath amp Low cost / good value Includes RCA and 3.5mm audio inputs Quality power supply included Plenty of power for entry / mid bookshelf speakers Cons: Bright led in the volume knob Click/Pop sound when power is switched on/off Always on / no power saver (note, I prefer this as mentioned in the review it will play even at very low volumes) Review: A nice amplifier even on high end speakers - This review (Jan 2020) is for the newest version Kinter tripath 20 watts/channel amplifier. I tested this amp with my studio monitors, which are a pretty awesome Paul Carmody design rated at 80W per channel, 8 ohms. While probably some people will find it useful, I have no interest in using the built-in treble/bass EQ , so I can't comment on that. I appreciate the fact that there is a selector switch to turn it off and take it out of the signal path -- awesome design choice!! (There is an audible increase in volume from this amp when the EQ is deactivated.) The test: I played a few punchy EDM reference tracks through this amp and ran the volume knob at 1/3, then 1/2, then a bit less than 2/3. I do not enjoy over-the-top volume levels but I do enjoy feeling the bass a tad. At all settings this amplifier is really very good. It is in fact a bit punchier, and with a bit fuller low end at identical loudness settings, than a "classic" early 90's era amplifier that I own. Of course an 80 or 100 watt per channel full-sized amp will go louder for sure. But I really enjoyed the sound of the Kinter tripath. it is a solid sounding amplifier and has enough transient current sourcing capability to deal with punchy tracks where kick drums and similar excursions are important. The sound does have something nice (but very subtle) about it, which might be the "tripath warmth" that others commented on. For near field monitoring at my desk I found the volume of this amp quite adequate and the distortion free at all settings. Of course it would make no sense to compare maximum volume on this amp with the maximum of an 80 or 100 watt amp, so I won't do that. Likewise I have no interest in cranking this amp up until I hear audible distortion, and at maximum settings the THD likewise won't compare with that of a good quality 80 or 100 watt full sized amplifier. But that is to be expected for *any* 20 watt per channel amplifier, so expectations have to be realistic. It is an excellent 20 watt per channel amplifier, really excellent. The best I have listened to by far. Several of the reviews have commented on noise, but no, in my experience there is no such noise. I found quite the opposite -- it is a totally quiet, noise free amplifier. If your recording is noise free, this amplifier does not introduce anything audible. One review commented that this amp is a lousy headphone amplifier -- I want to address that. It's not a headphone amplifier at all. There is no place anywhere to plug a set of cans into. The 3.5 mm jack in the back, next to the RCA connectors, is an input. If there were any lack of definition, bass, or punchiness, I would have heard it. Is it going to sound as good as a NAD? No, no, of course not. But it's a solid product, no problems at all. ## 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 | #197,922 in Electronics ( See Top 100 in Electronics ) #1,145 in Audio Component Amplifiers | | Brand | Kinter | | Brand Name | Kinter | | Customer Reviews | 4.4 out of 5 stars 1,370 Reviews | | Item Dimensions | 4.72 x 5.79 x 1.65 inches | | Item Weight | 16 ounces | | Item dimensions L x W x H | 4.72 x 5.79 x 1.65 inches | | Manufacturer | Kinter | | Minimum Supply Voltage | 12 volts | | Model | K2020A+ | | Mounting Type | Surface Mount | | Number of Channels | 2 | | Output Power | 20 watts | | Part Number | K2022A+ | | 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 ![Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black - Image 1](https://m.media-amazon.com/images/I/71+0JAFy1-L.jpg) ![Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black - Image 2](https://m.media-amazon.com/images/I/71Dr1+mdg4L.jpg) ![Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black - Image 3](https://m.media-amazon.com/images/I/814W-edDrOL.jpg) ![Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black - Image 4](https://m.media-amazon.com/images/I/71DkQBceN9L.jpg) ![Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black - 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 ### ⭐⭐⭐⭐⭐ While searching around I happen to see someone recommend this Kinter limited edition amplifier as the only one ... *by D***W on April 3, 2018* I ordered this because I missed out on the original Tripath 2020 craze from a couple years ago.

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. ## Frequently Bought Together - Kinter K2020A+ Limited Edition Original Tripath TA2020-020 Class-T Hi-Fi Audio Mini Amplifier with 12V 5A Power Supply Black - Amazon Basics 16-Gauge Speaker Wire Cable, 100 feet, Bronze - Micca M-6C 2-Way in-Ceiling Round Speaker, 7.6" Cutout Diameter, Whole House Audio, Home Theater, Indoor or Covered Outdoor, 6.5" Woofer, 1" Tweeter, White, Paintable, Each --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/60293257-kinter-k2020a-limited-edition-original-tripath-ta2020-020-class-t](https://www.desertcart.com.pa/products/60293257-kinter-k2020a-limited-edition-original-tripath-ta2020-020-class-t) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-09-16*
