This is my first time owning a Class A power amplifier and I can't be more impressed with the build and power quality of this amp. I'm using Infinity SM 150 studio monitor speakers and they sound amazing for 35-year-old speakers. I would like to give a shout out to Aamir, what an awesome salesman who will make your purchasing such a pleasure. Thanks Aamir & Summitt Hi-Fi I can't be more Happier
I recently purchased a pair of Paradigm Founders 100f for 2 channel enjoyment but was looking for an amp to power. I have tried a few amps in the past in various applications and again decided to try something new. I have purchased - SVS Elevations, Ultra Surrounds and Ultra bookshelves from Summit so I gave Aamir a call to see what he had. After chatting I decided to pull the trigger on the Tonewinner AD 1PA to power my new founders, I am very happy I did as the AD 1PA makes my founders sing. I have about 60 hours on both at this point and not looking back. Thanks Aamir!
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!!!
AD-1 PA - 2 CH Amp Pure Class "A" 100 Watts & A/B 300w (8Ω）
I preface this review by stating that I am not an audiophile in the sense that I do not spend thousands and thousands of dollars on my system. I do not buy, sell and replace pieces. Having said that, I know what I like. Above all I like good sound.
Many thanks again to Aamir for his sage advice and incredible customer service! He really took the time to understand what we needed and this fits the bill. We use the AD-1 PA solely for music. We have 2 separate zones that need to be played separately or together and needed something that wouldn't lack power. The Tonewinner amp blew us away. The sound is clear and warm and stays that way even when you increase the volume. No noticeable distortion. It handles providing amazing sound whether we are using high volumes while having a party with friends or if we are just sitting listening to music over a glass of wine. My only problem is I had to carry the thing up the stairs. Thanks Aamir. We'll be in touch soon lol.
