Tonewinner AD 5180 Update

After a few months using the Tonewinner AD 5180, the amplifier is flawless. Runs quite cool, and has plenty of power. It just got better. Changing my A/V processor from a Yamaha to the NAD M17v2 (Summit) made a significant difference. The AD 5180 now shows its depth, power, and finesse with both 2ch, and movies. Subtle nuances in both (especially) music, and movies are now revealed, which I never knew were there. What ever the NAD throws at it, is uncolored, super clean, and pure. It is hard to describe. I find myself listening to music at a much lower volume, the punch, clarity, and detail is amazing. I now own 2 '5180s! (5.2.4) To say that I am impressed with the Tonewinner AD 5180 is an understatement. I truly believe that to buy a better amplifier, be prepared to spend ALOT more money. Aamir has been instrumental in helping me make choices. With his product knowledge and guidance, I now have a system that has truly exceeded my expectations.

Clean sound

I've been running the 5180 for about 2 weeks. I notice a substantial improvement in the sound quality vs the amp in my Onkyo RZ920 much more headroom. I have it set up on top of my rack do to running on the warm side. If you are looking to place it inside a cabinet I would add additional cooling.The 5180 is built like a tank at this price point it's awesome!!

First, let me join the crowd by saying that Amir, the representative, was true to his word, even though it was costly for him, i.e., he delivered the product as promised, even though it had to be shipped overseas. And, it came very quickly, considering how far it had to travel - within a week. Amir answered all of my questions and is willing to stand behind his product.
Regarding the Amplifier: I examined many amplifiers out there, before I made the decision to purchase the AD-5180. I have only had the amplifier for about two weeks now and I am very please, so far. It really can't be beat. It has the same, or greater, specifications; high quality; and sold build of much higher priced amplifiers - very clean. The meter alone puts this unit above the myriad of amplifiers out there that are mere, non-interesting, boxes. And the meter serves a function: to indicate signal strength and show how much amplitude is going to its designated speakers. I would prefer the meter broke down the signal from each channel but, it is better than most other brands - no meters at all.
The sound quality can't be beat either. I have McIntosh amps on board also, as well as, McIntosh speakers and this AD-5180 delivers its signal equally well.
Final thought: I saw a review, on YouTube, that indicated that there was some low level hum, from the unit, when it was not sounding anything. I don't find that to be true. My speakers do not produce any hum from this unit. It is dead silent when not sounding anything.
I am very pleased with my decision to purchase the AD-5180. It is a tremendous value. I'm sure you will feel the same way, if they don't raise the price as it becomes more popular.
p.s. I'm not being paid to write this. :)

TW - AD-5180 AMPLIFIER 5 X 180W

Excellent service the 5180 is a real nice addition to my home system.

Worth every penny!

I was a bit sceptical on this but Amir assured me I was making the correct decision. I got my forklift out and moved it to my theater room (kidding, but it is hefty) have this running off a Denon X4500 with a Infiniti RC263 center, 2 JBL Studio 590 and Studio 530 for front heights and just WOW! It woke these speakers up something fierce, Midbass just hits me in the chest now! 100% clear and clean with lots of power on tap. It is also a vey nice looking amp and you can tell it is well made.
I tried an Emotiva Basx A300 and even tried the Crown XLS series, They both kinda sounded the same, Muddy and unclear, The Tone Winner is crystal clear, tight and clean. 100% would buy it again!
