    A unique added bonus, dynamics for days and stellar sound!

    I want to start by saying Aamir is just awesome to deal with. I have been a long time customer, and I can be hard to please lol.

    The AD1-PA is a world class amplifier at a fraction of the cost. The build quality is impeccable and the internals are well thought out and implemented. The sound is very detailed, nothing out of place, with incredible dynamics and nuance. I have had a lot of equipment come and go through my home, but I feel the AD1-PA's will be a long term stay. I love them even the more the more I use them.

    There is also a unique added bonus! These amplifiers have 2 sets of binding posts for the left channel, and 2 sets of binding posts for the right channel. If you like to do A/B comparisons with speakers like I do for my Youtube channel Spec of Tech, then this is incredibly handy. I can switch speakers with the push of a button for quick on the go sound comparisons. No big delay between listening, since we all know our audio memory is incredibly short. Not to mention you can easily switch between Class A power and Class A/B, another really handy tool to see what sounds best with a specific speaker.

    Are they worth it? Yes, they sure are and then some. They are worth it for the sound alone, and then you get some unique added bonuses that just add to the value.
