Customer Reviews
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!
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.
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 Monoblocks, 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!
