    END GAME!!!!

    When I was a young a hundred years ago, I promised that I would not be one of those old people that said things like “ In my day” Or any other nostalgic type of pronouncements. I did not keep that promise.

    Another promise I made and was able to keep (until today)was not to use worn to death phrases like. “I heard things that I did not hear before”. Or I went to my music collection and was replaying songs that I thought I knew inside and out. Bla, bla, bla.

    The Tonewinner AD-PA1 was to be my last component to be added to my system The goal;? “End Game” The final path was to be Pontus 2, 12th Edition DAC and Hermise Digital to Digital converter, then finally, the Tonewinner AD-PA1

    For reasons I will not bore you with, I decided I would get the amp first and then the D to D converter. Good move. Why? I was able to establish such a performance base line, that no matter what I now add to my system it’s contribution or detriment would be seen right away.

    One owner said that this beats out Krell and a few other of the big time players. Well I never had those in my system. No doubt it beat my old Parasound, Steve McCormick DNA1 and My Audio GD, and my PS Audio s300.

    Here is just one of the things that blows me away. I have a few CD’s that say how well they were recorded or remastered. Some I just said “ Meh” when I heard them. The Jazz ones that I had that were remastered my Esoteric seemed harsh and over done. Another recording that I was never was Francis Albert Sinatra With Antonio Carlos Jobin. I played it and it was if I had just heard it for the first time in life. Well as the saying goes' . It’s not you it’s me.
    Now I fully enjoy my Esoteric pressing and other CD because up Until now my systems was just not up to par. Thanks to the Tonewinner those days are over and my system is at a level that I never dreamed of when I ordered it. I can honestly say
    These two words. END GAME!!!

    Tonewinner AD 1PA

    I have been a loyal customer with Summit HiFi for a few years now. I really enjoy trying new gear in my system. So far I have purchased quite a few items, including; SVS prime pinnacles and center, SVS SB4000, and a SB3000 sub, NAD M17v2 processor, Legacy Classic HD, and Silver screen center ch, and 2 Tonewinner AD 5180 5 ch amplifiers so far!! Some pieces I have since sold and upgraded. I use my system mostly for music lately and really enjoy it. But still love watching movies too!
    For 2 ch I had a pair of PS Audio M700 Mono blocks, which were great and very much enjoyed them. Aamir always teased me, saying the Tonewinner AD 1PA would be an upgrade. I really like the TW product, I still have the two 5ch amplifiers. A friend, who has a You Tube channel, here in Calgary, has the TW AD 1PA amplifier. We did a comparison between my PS Audios and the AD 1PA. Aamir was not kidding about the AD1PA regarding how good it is!! That was 3 weeks ago. I called Aamir that day, and humbly said "you are right, again!!!" The mono blocks are now gone, and within 4 days I had the TW AD 1PA at my door!
    I have about 30 hrs on the TW now. I am very impressed so far! and it just gets better! All my listening has been in Class A. This Amplifier is by far the best I have ever experienced. The 3 dimensional soundstage, instrument separation, layering, imaging.... just fantastic! Live recordings have "Air" and great depth. Highs sound "real" no excessive sharpness or harshness with great detail, vocals sound so natural its amazing! The bass is "Anvil" solid, deep and extremely accurate. I have listened for many hours at a time, had to force myself to stop. This is one serious Amplifier with BIG legs! Has huge power, with finesse of a Surgeon. It will drive any speaker out there. This TW AD 1Pa is truly a high end audio product, build quality, its sonic attributes, and looks truly exceed its price. Even double! I must thank Aamir for his honesty, knowledge, and impeccable customer service and support! Ps, BUY this Amplifier!

    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.

    Björn Hallén
    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.
