Awesome amplifier for my desktop speakers

2026-01-23    -Carlton Blueboy

The media could not be loaded. I agonised over selecting an amp that would do the job and I am really happy with my decision. This amp is running a pair of B&W 686 S2 desktop speakers and I am just loving the sound this little amp drives out. Bluetooth connection is solid. I have not bothered to use the other inputs at this stage. The remote is a nice touch also, and makes using the amp a breeze. The controls on the amp are also nice to use…I am very happy with my purchase.

5.0 out of 5 stars Budget with high end capabilities

As an experienced semi-audiophile person, this amp has excellent sound quality. I have been the owner of multiple amp and speaker systems from the 70's until now. Several things make this unit standout ... namely the sound quality, build and small size of the amp. The tubes look great and of course help give the audio good quality. I hear a slight amount of reverb on some music but cant quite put my finger on it. There is an excellent video on Youtube about the construction and testing these go thru. The remote is nicely functional, no non-working buttons and simple to figure out. I will test and compare with a vintage Pioneer SX1080 as soon as I can. Currently paired with some smaller JBL bookshelf speakers with about a 6 inch woofer (I'll update with the model number asap) . Good speakers will really sing with this amp. If you buy one of these and it doesn't sound good, think about upgrading your speakers. Bass is truly adequate but I think the high end could be a bit better. I will test with some Bose-901's, Dayton Audio B652's and some old Radio Shack Mach 1's for giggles. I steam Amazon music via small tablet using Bluetooth. That has been working and sounds fine but I do hear a relay click from the amp at odd times when there is no music playing. That has been noted on the T9 also -- not a huge problem but slightly annoying since the amp is close to my listening chair. A nice FM radio and another set of inputs would be icing on the cake. I'm not interested in changing the tubes but may shop for some spares as I have no idea how long they will last but with a low heater voltage and the mil spec, I would think they will last a long time. Updates to come, so far very good, I'm impressed and happy with the purchase.update - reverb was coming from a program I use to tweak the sound from my test tablet.JBL - older Northridge E Series E30 -- the current home for the amp. A great match, on the floor for now- will experiment with some speaker stands latter) . This setup got me back into truly "listening" to music again. I would like a hair amount more of high end but love this setup. Fantastic off center imaging. Starts clipping at about 85.901's - (with out the EQ) - Best I've heard these speakers sound yet. Not as efficient and had to play the amp at higher volume to get descent sound volume but also sounded great. The amp played at louder settings with out clipping ... This was the best match up for the loudest DB's. I tried my old 301's but they didnt sound near as good but I didnt have time to tweak. But again .. it drove them just fine.Mach 1's - I've replaced the 15's (I forget with what) but they totally brought out the tube "warmth". No muddling or over powered bass. If I had room in my listening room, this would be my go to speaker. Clipping before they got too loud .Dayton Audio B652-- 6.5 inch woofer holds it own. I switched to them after listening to the Mach 1's and it was like night and day bass wise lol. Still pretty good but the JBL's have them easily beat. Very nice image separation and nice high end.Very fun playing this with ANY speaker. If you want LOUD, this is not your amp. But if you'd rather have 35 or so watts of great sound. Check this amp out. I'll compare the Pioneer soon. I suspect it will keep neck and neck until the power goes past the T9's abilities.VS Pioneer sx1080 - Dixie cup to Stanley ... the bigger receiver just plain has more power. The Pioneer easily sounds better at low volume levels with better overall tone but its not a fair comparison honestly but it was fun to compare the the same speakers ( some old Athena tower speakers). The T9 pro still sounded great though.Riverstone5654 tube update - slight increase in low end and channel separation. The Riverstone does a great job of packaging and documenting. I hear more detail and like the result. Seems worthwhile, but i cant see spending any more money on this unit.Hooked up a DVD player and connected it via the digital co-ax port. I have not used the optical port yet. That portion of the amp also works flawlessly and sounds great.

Impressed!!

I've been doing a lot of research on small class D amplifiers and after too many hours I settled on the T9 Pro. I am using my PC as the source and wanted an amplifier with an integrated DAC so that I could output the signal digitally via an S/PDIF cable and let the amp convert the signal to an analog one. I also have a fair bit of high res audio files and am glad the amp can process up to 24 bit 192khz signals. I am using the T9 Pro to power a pair of KEF C55 speakers that are quite large bookshelf speakers with dual 8" drivers with the top one having an integrated tweeter. They are rated to 150w at 4ohms.Now with all the preamble out of the way... all I can say is WOW! It is beyond impressive that such a small amp can effortlessly power such large speakers. The sound quality is phenomenal! I started with a 24 bit 192khz version of Louie Armstrong's "La Vie En Rose". I was blown away by the trumpet during the intro. It felt like he was right in front of me playing and the separation of instruments and sound stage were both really impressive. Once the vocals started I was also really blown away by the clarity. I next played around with a mix of different genres (I have a pretty diverse taste in music) and I felt that it could handle everything from classical to rock. The bass felt a touch low for my taste but the included remote makes it a breeze to make adjustments to bass and treble. This will be up to personal preference of course.The T9 Pro ships with a 32v 5 amp power supply which equates to 160w. If you are using this with a computer, make sure to set the S/PDIF output to 24 bit 192khz so that you get the best quality possible (if you are playing high res audio).In summary, I cannot recommend this amp enough, the value is superb for what you get. As a note, my main home theatre setup is powered by a $3,500 Onkyo 7 channel integrated amplifier so I have a great reference point at a much higher price point. It really speaks to the efficiency of class D amplifiers and the quality of the Texas Instruments chipset in the ability of this tiny amp.

5.0 out of 5 stars New and Improved T9 Pro - Problems fixed!!! Best all-in-one amp

2026-02-27    -Quang

I was a previous T9 owner and paired it with a set of KEF Q150 bookshelf speakers. I did some research and thought the T9 was the best all-in-one amplifier for the money. I used the amplifier to power my bookshelf speakers for my computer via USB and TV via optical. I am no audiophile (this was my first amp/bookshelf speaker setup) but it definitely provided clearer/cleaner sound then my klipsch pro media speakers. I did see and read the reviews about the "clicking" and thought it would not bother me. But after using it for month or so it would actually really bother me. Not only did it click all the time when switching between sources, but it would turn off/go in standby mode if not used for a little bit then click on again when sound came back. Very annoying.Then I was browsing amazon one day and noticed they released the T9 pro and looked at a couple reviews and they said the clicking was gone. Decided to try it out and I am so glad I did. THE CLICKING IS GONE!!! Not only is the clicking gone but the amplifier itself is more aesthetically pleasing. The tubes are shorter and slightly wider allowing it to fit better on my desk. I also like that there is now a digital screen that shows you the volume levels as opposed to the T9 when it was just a never ending, spinning knob. The digital screen provides a cleaner look, removes all the excess text on the amplifier and will also tell you what source you are connected to.As stated, I am no audiophile so I cannot tell much difference between the sound quality of the T9 and T9 Pro, but for the reasons listed above I believe it is well worth the $40 upgrade and I would highly recommend it if this is your first amplifier. It provides all the connections/inputs you would need. Is small and compact, but provides quality power and sound.

En las especificaciones de la app, indica que es de 200 watts de potencia. El manual que trae el producto dice 100 watts.. El prodicto es bueno; sin embargo, si se nota la baja potencia

5.0 out of 5 stars Use a a preamp for A07 max and upgraded power supply - Awesome

I have had this little amp for many months. It’s fantastic and a great value. For a while, I did feel as if I wanted it to get better volume without maxing , but I was able to remedy this. After looking everywhere to see if I can plug this into the A07 max and basically use it as a pre amp, i decided to try it myself. I also got the upgraded power supply for the A07. (Makes a huge difference). I also upgraded the tubes in the T9 pro with the $25 riverstone audio pair from amazon. IT IS WORTH IT.Essentially, my T9 pro is being used as a pre amp with tone control and DAC into the A07 with upgraded power supply. This opened up the sound stage, gives me the volume and adjustability I wanted, and looks cool with a small form factor. I also have the x2 pre amp for my turntable with upgraded tubes. All in all for a pre amp, upgraded tubes, upgraded power supply, t9 pro and A07 max, you have a full set up that you can have a turntable attached and television. It worked great with my a/v switcher too. At one point, i had my TV, a cassette deck, and my phono pre amp all hooked into this thing running through Kef q350 speakers. it is extremely fun messing with all of the items like a lego set.THE SOUND-TurntableGet an external pre amp. The sound is crisp, and clear. Beyond impressive for its price point. It is a little thin on the bottom mid range and upper mid range, but the dynamics are awesome and you can hear the instruments in the music. I test everything with “Rhiannon” from Fleetwood mac, it really sounded awesome. I do not find that it adds to much distortion or clipping even when volume is maxed.-TVThrough the optical table, it sounds great. I sometimes like just playing my playstation through a simple 2 channel set up in my small media room. It’s easy to switch from the remote and adjust the treb and bass as needed while sitting in the couch.-BLUETOOTHMy 1 knock. The bluetooth on this thing sucks. The connection is fine and if you just have background listening it’s whatever. But it is VERY thin sounding. Still a great feature to have. I think you would be better set getting a blue tooth adapter.OVERALLAwesome little amp with great sound and looks. Sounds even better when paired with A07 max and upgraded power supply.For the average listener, so worth it. I mainly listen to my music on a vintage pioneer amp, but I still put this on regularly.For someone starting off on a vinyl or hifi journey, especially with a tendency to hyper focus, save and get higher end equipment. You WILL keep adding little parts to this that will rack up to be the same as just getting a few mid range pieces.
