I don't get LRS and cheap Ayima AO7 amp


Interesting story, I have an real nice tube amp Harbeth analogue system setup which is great. I ordered a Magnepan LRS for the goof a while back. Got it like 5 months later didnt think twice as it was put aside. I needed a cheap amp and DAC for an inceiling kitchen system. Ayimya ao7 $90 and a topping E30II $150. I hooked them up to Maganepan and I was shocked at how good it sounded.  How is this possible? I dont get it....  I have heard very expensive systems 70K+ . Are we being ripped off. I am not comparing the two so lets not go down that road....but what gives....

I'm interested in this Aiyima amp. I bought a Tripath amp based on Rolox's recommendation. It sounds lovely with my Closer Acoustics OGY. But I wish I had more power for orchestral music. With other music it's plenty loud.

With the A-07 one uses more or less voltage in the form of the SMPS to get higher wattage.
50ish volts gets a few hundred watts, so I got one of those SMPS for the center channel.

@holmz I'm sorry, I don't understand your post. You're talking about an engineering concept. What are the consequences? Should the A07 and Tripath amp sound very similar?

Anyways, I thrifted a Continental Edison PA9109 for 40€ and couldn't be happier. I get a bigger, punchier sound. I'm no longer interested in these class D amps, because I'm satisfied. 

I wouldn't be against using an Aiyima A07 for a few days to make up my mind. But I can't justify another amplifier purchase.

If you need more power, like maybe driving a 8 ohm load… then to get more power one uses a higher input voltage.

There is a yellow and blue table here: 

Figure out what power you want/need, and order the power supply that fulfills that need/want.

 

I do not think it is the best amp in the world, and comparing it to a Bryson, Parasound, Pass, etc. seems a bit of a wank.

But it is the best amp at $62 (USD) IMO.
