Let me explain ... I initially bought a Denon amp. Then, I bought the Cerwin Vega XLS 12 speakers. Well, the Denon amp was nearly not enough power for them. So, I bought a NAD amp that puts out 150 continuous RMS (supposedly). Still not enough power, the amp would cut the speakers off at higher volume. I then discovered the TW AD-2500 amp through Summit. Aamir called me back, and I can tell you that this guy really knows his stuff! He answered so many questions that I could never find on the internet. I don't know how many forums I looked for answers to, when he was the one I needed to ask the whole time. He is also very accommodating and friendly. Easy to talk to. Besides the service, I hooked up the amp, and it sounds superb like he promised it would. So clear. So detailed and clean. And, powerful! I've had no problems cranking up these speakers, without losing sound quality. There is only one problem ... I think I need a bigger house!
Recently purchased the AD2500 from SummitHifi and could not be more pleased. Yes, I was expecting a pretty good amp, but this goes way beyond my expectations. Build quality is excellent. I looked into buying an Emotiva or Monoprice flagship amp but the Tonewinner puts both of them to shame when it comes to builid quality. The sound quality is excellent. My Magnepans 1.7i have been taken to a new level with this amp. The ease and authority that in runs theses speakers is quite astonishing. The clarity and micro details are impressive. Finally, this beast of an amp is just beautiful to look at. Highly recommended.
very satisfy in music this amplifier mutch power but sound very smouth ,I like.
I did my online order on a Wednesday.
My fist surprise was to receive a call from Aamir the same day to confirm they received it and to thank me for it. How many times did I receive a phone call just to confirm and thank me for a purchase I did over Internet? Never. First time. This is the kind of Customer Service that other companies should take note of.
My second surprise was to receive the shipment Saturday of the same week. For a delivery from Ontario to Quebec, especially with all delivery companies experiencing delays in these days, that was amazing. The amp was professionally boxed too. And the shipping was free!
The third surprise was the amp itself. What a tank. Over 50 lbs, massive, with very hi-end components. Obviously, this amp is built to last and to deliver.
I just finished installing it in my system and I will test its audio qualities over the next days. But I’m very confident. I will let you know soon about my listening sessions.
Sincerely, congratulations to you guys. I will recommend your company to anyone without hesitation.
Very happy, fantastic service and quick delivery. An immediate improvement all around, greater clarity and less fatigue on the highs, midrange was the biggest improvement with more detail where it seemed all washed together before and the bass is more accurate and just has more presence. The Polk RTI a9's the amp is powering are buy no means top tier audiophile gear but they are power hungry and this Amplifier definately woke them up, worth every penny! Amir is great, little details like a phone call to personally thank me for the order were a refreshing change from the big box stores.
