5.0 out of 5 stars Bought new - SENT REFURBISHED UNIT!
UPDATE #2, April 7, 2024: I am bumping this to 5 Stars, why?Kinter reached out to me and offered a FULL REFUND of my Amp, Kinter MA170. I didn't expect any sort of refund, after all, the unit was Waaaay past the 30 day return window. However, Kinter DID NOT want me to return it, apologized for the error of my getting a refurbished unit and not a new one. I actually told them I didn't expect or even want a full refund, but would accept a 50% refund, so after a message or 2 between Kinter and myself, Kinter gave me a 100% refund. This was, and is way above your normal customer service, it shows me Kinter cares about their product line, and their customers satisfaction. I also told Kinter what the main cause of the issue causing the Amp to randomly turn off/on, or just shut down was, that the Amp heatsink was too long, that it needed to be shimmed down by 2/32 of an inch to prevent contact with the Amp IC leads. Kinter also stated they upgraded the Amp IC, which is a little smaller, but they still used the same heatsink from the older Amp IC. And the person I messaged with is also passing my heatsink fix on to the manufacturer for implentation.Hence the shorting issue that occurred in my Amp, that caused the issues I had will be corrected. Which I had fixed, info on the fix can be found in my April 1, 2024 UPDATE below. So, this is why I am bumping my review of the Amp to 5 stars.Also, after correcting the oversized heatsink, so it no longer made contact with the Amp IC leads, I let my Amp operate continually in my shed for 6 days NON-STOP, in those 6 days, the Amp operated 100% normally, no drop outs, no shut downs, no random going off/on.Now that my fix is in place, the Amp has functioned far exceeding my expectations.So, yes, I can recommend this Amp and this Seller. Top notch 1st rate customer service that was above and beyond. ======= END April 7, 2024 UPDATE #2 =======UPDATE April 1, 2024: I am bumping this up to 3 stars, mainly due to I found the PRIMARY ISSUE causing many of these units to stop working, or going off/on randomly when music is being output through the amp.And it is a simple fix, but WILL REQUIRE you to open the unit and take it apart, and I'll tell you what I found, and what I did to correct the issue.I removed all 10 screws, 4 from back panel, 4 on front panel, 2 screws from right side[these screws are a different size and type, they secure the main case housing through the amp IC heatsink, don't mix them up with the other 8 screws that hold the back and front faceplates to the main case!]You'll need to remove all knobs to access the securing nut on each, the main volume knob nut is recessed and will require a deep socket, or long needle nose pliars[I used needle nose pliars] to remove it[and the other nuts on the Bass and Treble components], beware, once you remove the nuts, the Bass and Treble knobs have a securing ring[slips on/off] on them behind the faceplate.Don't lose them, you'll need to put them back on the Bass and Treble knobs BEFORE reinstalling the faceplate over the shafts. Do this step[remove knobs and retaining nuts] PRIOR to removing the screws that holds the faceplate on. Once the nut has been removed from the volume control, slide the clear plastic ring off the shaft, there are 2 small protrusions on the back of this plastic piece, either one fits over the power indicator RGB color changing L.E.D. to hold it in place properly.Once opened you can change out this L.E.D. for any color L.E.D. you'd like to use, just make sure the polarity matches correctly + to +, - to -, or remove the L.E.D. entirely, your choice.Now remove the 4 screws holding the faceplate to the main casing, if you have already removed the 4 back screws, and now have the front faceplate removed, gently slide, by pushing the entire assembly minus faceplate out the back of the main case.You'll see a metal casing over the Amp IC, this is the heatsink that screws to the main casing. And this heatsink is what caused my unit to initially fail!After touching up some of the solder areas, I tested the Amp, but forgot to place the heatsink back over the Amp IC.The Amp played for over an hour, no issues UNTIL I realized I had not placed the heatsink back over the Amp IC, as soon as I put the heatsink on, less than a few seconds the Amp started randomly going off/on, or completely off, started up all over again. I used the needle nose pliars to place, and remove the heatsink.Okay, issue is back...why?I found the heatsink was making contact with the EXPOSED METAL LEADS of the Amp IC.I got out my dremel tool and shimmed the heatsink down 2/32" at ONLY THE AREA THAT COVERS THE AMP IC!DO NOT SHIM THE WINGS WHERE THE SCREW HOLES ARE!So, I took my dremel tool[adjustable speed, set it at #1 on the dial] and then ground off 2/32 of an inch of metal off the [open area that slides down over the Amp IC] heatsink, replaced the heatsink, no more random onn/off, no more Amp turning off all sound.Chances are THIS IS THE MAIN PROBLEM many users are having with this Amp cutting off/on, then going completely silent, but the power L.E.D. still shows power to the Amp.If you're not comfortable soldering, or using power tools to do this, find a friend, or pay someone to do this for you. But, if you have an Amp malfunctioning like this, this may get it working again, providing the heatsink shorting the Amp IC hasn't destroyed it.Fortunately I caught this early in my testing, and was able to resolve it before the Amp IC was destroyed.As of this update, and after shimming the heatsink down, so it can no longer make contact with the bare metal leads of the Amp IC, the Amp has been working perfectly 100% for over 9 hours straight and no problems at all, and inside a very hot storage shed, about 97°-100° in there today[no windows, no ventilation and door closed].If the heatsink was shimmed down by 2/32 of an inch at the manufacturing facility, and/or the Amp IC's leads had been covered so the heatsink couldn't create a short, I probably would have never taken my Amp apart to fix this issue, as it, in all probability may not have ever happened!If it wasn't for my having to fix this issue, I'd have probably rated this Amp 5 stars, but it gets 3 stars, it works, but only BECAUSE I FOUND, and FIXED the problem!I hope this info may help some of those experiencing these same issues get their Amp back up and operational again.≈========/ End April 1, 2024 Update =========Unfortunately my return window closed a long while back[bought this at end of Dec. 2023] and just now got around to testing it out, and I connected everything up for testing BEFORE I mounted this in the enclosure it was be going in with an MP3 Director and FM Transmitter, only the MP3 Director would be connected to the Amp.Well, I set it up using a portable CD player[testing only] to the Amp, and connected the 8-ohm outdoor speakers I use every year for my Holiday Displays.Connected power supplies, turned on Amp, turned on CD Player, turned up volume on Amp, had preset Bass and Treble knobs to center, music played through the Amp, then in LESS THAN 1 MINUTE AFTER TURNING AMP ON, music started going off/on at random, this went on for LESS THAN ANOTHER MINUTE, then the AMP JUST SHUT DOWN COMPLETELY WITH NO SOUND AT ALL.Turned power off and back on, amp played on/off music for LESS THAN 30 SECONDS, and then COMPLETELY SHUT DOWN AGAIN, NO SOUND, just that annoying RGB L.E.D. showing power, but nothing else functioned.Now I was an electronic tech/touch-up and repair person for many years, refurbished many things in my time, and I know what to look for to know if an item has been REFURBISHED, [I NEVER BUY REFURBISHED PRODUCTS, MOST OFTEN THEY FAIL QUICKLY, usually just past their warranty period, some never make it that far, refurbished items ARE NOT Q.C.'ed or tested like new products are(or should be), they are "Quick-Tested", power it on, it works, out it goes for resale, or back to the original customer.] Anyway, I opted to take this unit apart, one of the knob shafts was broken and fixed with a type plastic substance to make the knob hold the button on, when I took the button off for taking this apart, that plastic used was white, shaft was black!, and this substance cracked and splintered some. That's one tale-tell sign of a refurbished hack job, the component should have been replaced, not a jury rig fix. Missing solder on solder pads that may be used to hold components in place to prevent damage from movement was also noticable on the circuit board, very poor Q.C., even for a Quick Turn-Around repair.After, I took it apart, did some resoldering to many components, and used a computer fan to keep the amp component cool, it seems to work.But I shouldn't have to be modifying this unit!Before I reassemble it, I'm going to replace that damn annoying color changing L.E.D. to a white one, so it can supply some light inside the outdoor enclosure, so, when opened after dark to make changes, I'll have some lighting, as my lighting controller[the MP3 Director] and FM Transmitter will also be inside. I will also see if there is enough room to install a small cooling fan inside the amps case and drill holes for it to push any excessive heat out to hopefully keep it functional.But because I DID NOT RECEIVE A BRAND NEW UNIT, was sent a REFURBISHED ONE. REFURBISHED UNITS ARE SUPPOSED TO BE IDENTIFIED with a tag or sticker stating this fact! .And from reading many of the reviews that also bring these same issues up, sounds like they got a REFURBISHED unit, just like I did, and NOT A NEW UNIT!Very disappointed in this purchase, especially since I have to try and repair it, and "hope it works", and "hopefully, will last for many years" after I fix problems that should not have been here in the first place!
5.0 out of 5 stars It's small, it's cute, and it's LOUD enough.
I don't have an eight foot wide TV on the wall, I'm not trying to fill an auditorium with sound. I have this Kinter amp, a pair of Sony speakers and a Sony DVD/CD player and a monitor. Set up on a table. I sit a few feet back from it and watch movies, or I crank up the volume to play CDs and can enjoy the music in the next three rooms over. It's not some sort of 5/1 surround system, it's old fashioned two channel stereo. It's all I want for what I need it for. Good volume, clear sound. If you grew up with huge amplifiers in wooden crates in the '70s, it's amazing how small this thing it.This one has a push button "on/off" and the volume knob has LED lights that cycle through five colors. If you might find that distracting I think the previous version of this amp with an "on/off" toggle switch and no lights is also still available - might even be a few dollars cheaper. The controls are pretty basic; on/off, volume, bass and treble. (a balance control would be nice though...)If you need to impress your friends with a home entertainment system this might be a pass for you, but if you just want to watch some movies and listen to some rock'n'roll, you can start here and put together a nice economical little package.
4.0 out of 5 stars neat little amplifier, seems to be quite powerful
This is a neat little amplifier, very handy for when you just need to add some small bookshelf speakers somewhere. Am I I want to say it's audio file grade no. By no means is it. It's just a basic amplifier that's easy to use volume and tone controls, a balance control on a power switch. The only thing I really didn't like about it was how short the power cord was on the power adapter, not even long enough to get off the desk to a power strip. Can also speak to the true output power however it does get quite loud. I would say at least making about 10 watts. Distortion is a little higher than expected. Also don't operate this much below four ohms it's not happy about it the Distortion increases quickly. And so far it's worked really great to power some bookshelf speakers by my computer for basic audio editing. I've been in broadcast and recording engineer for over 30 years and I've used probably a few thousand amplifiers in my life. Really good and useful amplifier for the price. Just needs a longer power cord
5.0 out of 5 stars As advertised
Compact design with simple, well marked terminals. Perfect for adding a set of old speakers to a cable box. Inexpensive and full featured.
5.0 out of 5 stars Small and useful
This small amp is pretty cool! I set it up on our bedroom tv so i could put a speaker by the wife’s side of the bed so she can here the tv better while im sleeping. Great sound and one super happy wife! Setup was easy and im gonna get another one for the downstairs tv soon.
3.0 out of 5 stars Sound Amplifier
Does not give me the "umph" I had anticipated. Product is ok but nothing to write home to mama about. Would have been worth a few buck more if a remote control and mini-to-RCA cable was included. I give this a rating of 5 out of 10.
5.0 out of 5 stars Awesome Product!
This little amplfier is a powerhouse. Volume control, color changing lite, bass, treble, great value for the money. We use it to amplify 3 large speakers hooked to our tv. 2 behind our seating area and 1 in our kitchen. Works great as a surroud sound.
4.0 out of 5 stars Simple & easy
Product very simple and easy to install , had two very old speakers hence I got this very inexpensive amp connected to a Bluetooth adapter and my echo dot works like a charm . Got it all hooked in my garage . Cheap stereo hookup. Again please remember it has a audio input so you do need to buy a Bluetooth adapter Logitech has real cheap ones in order to connect it to a echo dot or any other modern devices
Gran artículo a precio razonable.
Me gusta su funcionamiento, para ser la primera vez que utilizo un amplificador. Funciona excelente.Espero que siga así y sería genial.Muy bien producto.Gracias !
Potente
Buena potencia de salida, control de bajos y agudos pero carece de control de balance. Lo uso en mi sala con cuatro bafles bastante añejos y ¡Listo! Mi home teatro casero.
Me gusto Kinter Ma170+!
Me gusto este mini amplificador, es justo lo que ocupaba para conectar mi Roku a este pequeño aparato y aprovechar unas bocinas Sony viejitas que tenia por ahi, ya solo falta ver si me dura, pero en general bien.
Sorprendente
Tenía una bocinas sharp arrumbadas perfectamente soporta las 2 bocinas de 50W la verdad me sorprendió bastante, es lo que pagas, económico y funcional, hay ocasiones que los graves se escuchan mucho pero solo es cuestión de arreglar el grave y agudo desde el aplificador
Excelente producto, pero si buscas fidelidad, invierte un muchu más
Es muy potente para su tamaño, lo conecte a un par de bocinas que tenía arrumbadas, y tiene potencia, lo que le falta es fidelidad, pero me agradó mucho su respuesta, esperamos que dure una buena temporada.Buen producto.
