    Outstanding Amplifier

    I came from several different receivers and amplifiers and just could not find anything good. I came from Arcam sa30, onkyo, marantz, rotel, Parasound and odyssey audio. Either they just lacked power or the bass and midrange was just not there even though they claim to be the best. So after reading reviews and watching some youtube videos i went ahead and contacted Aamir. He quickly responded to my email and he explained his product with detail. I am simply blown away with the level of customer service and response time that I experienced with Aamir. He gave me his cell phone and he even texted to help me with all of my questions and concerns with this amplifier.
    Since i received this amplifier, i have watched several movies and listened to a-lot of music with absolute amazement of how detailed the sound is. I love strong bass so when i heard this amp for the first time plugging it in i was simply blown away of how detailed, strong and fast and clean the bass is. Its not over powering at all, just clean and strong. My Arendal speakers have never sounded this good with any other amps that i have purchased. It also makes the speakers totally disappear and almost sounds like i have a center channel when i don’t. My system is set up as a 2.2
    I am hearing things in movies and music i have never heard before. Even the smallest of sounds just come out, i dont know this happens but it does. It is weird how one amp to another can sound so different. I know, I know it sounds cliché but it is true. Every review i have read on this amp and processor are true. The quality if this amp is outstanding. When you take it out of the box be prepared to wear a safety belt because it is HEAVY. The packaging is perfect and strong to handle this. No damage at all.
    This amplifier does get hot and will need plenty of ventilation. I even asked Aamir if the heat is a concern and he re assured me that it is so well built that it will be just fine with adequate ventilation.
    I am finally done searching for “that right amp”. This is absolutely the best priced and performing amplifier that you can buy. Stay away from the big box stores and get treated the way you should with Aamir. He treats you with respect and will go out of his way to help. Heck, you’ll swear that you have know him forever. All the other Big Companies that spend more on their advertisement than they do on the quality of their product and don’t teach basic customer service skills, really need to take a lesson on customer service from Aamir.
    Great job Aamir

    Hope this review helps with your decision on this amp.

    New clarity and depth from Tonewinner AD-1 PA

    The amplifier is an outstanding addition to my system. Excellent clarity and detail with very good transparency. Makes the speakers disappear.

    Tone Winner AD 1 PA

    I agree with you! It sounds very clean, airy and controlled. There are also quite good resources. My speakers are not difficult to drive, Magnum Signature 707. I think, however, that you can go with really big heavy things. In class b mode, it stays really cool.
    This is a nice amp, the build quality also feels good.

    Personal Review of the Tone Winner Ad-1PA

    After 2 weeks and over 100+ hours of break in period of this amazing amplifier I have finally sat down and for a period of two days and over 10+ hours of nothing but heavenly listening sessions here is what I think of the Tone Winner AD-1PA.

    This Class A Stereo Amplifier is without a doubt the best amplifier that I have ever owned at any price. I have been an Audiophile for more than 25 years owning nothing but the best in high end audio equipment up to the $25K price range. I have owned Pass Labs, Mark Levinson, McIntosh, Bryston, Krell, Musical Fidelity, P S Audio, Classe, Parasound Halo ( JC1 Monoblocks) and this Tone Winner AD-1PA has a lot of the qualities of many of this amplifiers but it brings them to another high end level of sound that I have not being able to find in any of those previous well made amplifiers that I have owned in the past.

    Please, I want to make very clear that in no way I am saying anything bad about those previously owned amplifiers. I have enjoyed the time that I had them but there was always something missing that I I could not figured out what it was. That's why in my search for music nirvana I kept looking and switching amps. It was until two years ago that my last Stereo Amplifier was the McIntosh MC-452 . Nice sounding amplifier but it was too lay back for my taste. Not a bad thing if you like amplifiers that have that sound but for my taste it wasn't what I was looking for. I sold it to a very good friend of mine and I was without an amplifier in my system until I decided to give this AD-1PA a try.

    For many years here in the United States in the high end audio world many of us are led to believe that audio equipment made in China is nothing but low end equipment. That is not made to compete with "high end " expensive audio brands sold here in the US. That if the equipment does not cost a lot it may be cheap. And although in some cases some of this high end equipment made in China may not have been built with high end parts this is not the case with this Tone Winner Brand. I spent a lot of time researching this particular amplifier and found out that it has been built with nothing but high end quality parts and over all it is a well built high end amplifier. But to me what matters is the sound and this amplifier takes the music to the next level and this is why,
    1- Highs- The sound is so crystal clear and transparent . You can spend hours listening without feeling fatigue that's associated with metallic sounding highs. Outstanding sound dispersion and quality between instruments and vocals. Just perfect !
    2- Midrange - So luscious sounding. The sound is more natural with a midrange and grain free treble. The imaging and precision of the instruments is the best that I have heard. The soundstage is wide and deep . It is such a delight listening to it because it is so warming sounding. Everything sounds with such a terrific balance and tonality that you can spend endless hours listening to it.
    3-Bass - Wow! All I can say is , Wow! I did not expect this amazing low end bass extension. It is as if the bass hits the low end notes with authority but not being boomy at all and then it extends so heavenly and sublime across the room . It hits the low end extension with the speed that is required but in a perfect level of accuracy and detail. The best low end bass extension that I have ever heard in any amplifier.

    Do I care that this remarkable sounding amplifier was made in China ,Nah! not at all . Many kudos to Tone Winner for making such a wonderful sounding amplifier. If this amplifier was to be sold here in the US thru dealers trust me when I tell you that the price will not be $1999 it will be way more and perhaps over $5K . When you see this amp in person you will think that it will cost no less than $10K . If there was a blind test perform with this amplifier and or if you were to cover the Tone Winner name and just play it in a room with audiophiles and ask them how much do they think the amp will cost after listening to it I know for a fact that they will say at least $10,000 .

    My listening session was performed in pure Class A all the time. The amplifier runs a little hot but not to the point that you will burn your hands if you touch it. My living room just got warm but not hot and that was with the outside temperature being between 75 -80*. Many reviewers admit that Class A amplifiers and the most inefficient but they also admit that the best sound is obtain using a Class A amplifier. The Class A amp is inefficient if you just turn it on and leave it there as space heater doing nothing but if you are like me who is going to turn it on and enjoy the best sounding music reproduction that a well built Class A amplifier can offer then the Tone Winner AD-1PA is the Amp for you.

    Outstanding , Remarkable and Extremely Well Built Class A Stereo Amplifier

    This Tone Winner AD-1PA Class A stereo amplifier has to be the best Class A amplifier right now period! Just right out of the box this amplifier looks stunningly beautiful. The craftsmanship and high end parts used to built this a amplifier shows that it was built to be the best . Most people are lead to believe that China can’t built a truly high end audiophile quality amplifier but let me tell you that we couldn’t be so wrong . As a passionate audiophile for over 25+ years owning many high end amplifiers from Pass Labs, Mark Levinson , Krell , Ayre Acoustics , Marantz , McIntosh , Parasound Halo , Proceed and many others I have to say that this AD-1PA has surpassed my expectations in built quality and sound compared to all those amplifiers. Trust me , it is that good . You will not find an amplifier that can do what this one is capable of . You have the choice to have this amplifier play in pure Class A only as well as to switch to Class A/B is you prefer it that way instead or you can just set it to Auto and the amplifier decides when to switch from pure Class A to Class A/B . You have the choice at the back of the amplifier to connect biwired speaker cables or just to connect single wired and you can choose at the front how your speakers have been set up. This amp has 180,000 microfarads of capacitance which is enough power to drive any power hungry speakers . It is rated at 300 watts @ 8 ohms and 600 watts at 4 ohms This amp has an internal microprocessor that determines the current voltage of any country and automatically switches to that current without the need of a step down transformer.

    Just the first listening session of about 3 hours in pure Class A have left me amazed at the clear highs , lush midrange and tight bass performance . The sound was just outstanding and let me tell you that I don’t usually get impressed with the first listening session of any gear but this amplifier really did it for me . I was just laughing as to how good it sounded just right out of the box . Just as I have done with other brand new amplifiers before I will give this AD-1PA about 100 hours of a break in period to see what other heavenly level of sound this amp will take me . Trust me guys It is that good . This will show you that you don’t need to spend 10 times what this amplifier cost to obtain this sound quality . If you are interested in this amp Please give Aamir a call and order it . From the time that I placed the order to the time it was delivered today it took about 28 days . Please understand that due to the COVID -19 situation and delivery companies taking longer than expected it took this long but to me it has been the best investment I have done in audio gear and that’s why it was worth the wait .

    Thank you so much Aamir for getting this gorgeous and remarkable sounding amp for me . You professional and friendly advised was right on getting this amp.
