Good amp

After a little problem with customs everything went good. It arrived quickly with no issues. The sound is pretty good for the money it's a little light on bass but has plenty of power which I needed. So far I'm liking it.

TW AD-2500 from Summit Hi-Fi

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!

AD 2500 (Heavyweight Champion)

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.
