Once everything breaks in it will sound really bad.

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 $150. I hooked them up to Maganepan and I was shocked at how good it sounded. How is this possible? I dont get it.... I have heard very expensive systems 70K+ . Are we being ripped off. I am not comparing the two so lets not go down that road....but what gives....
I've been using exclusively those tiny class D amps in my main system and in my bedroom system. In the main system, tri-amped, I use a TA2024 tripath chip based Trends TA10.1, heavily modded, with a good linear PSU, and it sounds absolutely marvelous. When my friend purchased his vintage Audioreference 126Dc speakers, they sounded like crap with his existing Musical Fidelity amp... we tried one of my tiny class D (SMSL SA50, 70$) and it sounded MUCH better (poor synergy with the MF amp, probably, but still, we are talking a 3000$ amp vs a 70$ Chinese "gadget"). My budget is low, before switching to those little marvels I owned and tried many vintage / not so vintage class AB amps, some class A as well, but they were either disappointing OR unreliable. I'm not saying those are the best amps in the world, far from it, but the right ones sound very good, give them clean power from a linear PSU and they will impress, tweak them a little (capacitors, volume pot...) they will shine. For me, when you add on practicality, foolproofness, and the fact that they use almost ZERO electricity, there's no way back. |
Keep in mind that the high end world is often about chasing the last few percent of performance. If you spend 10 times as much, you don't get 10 times the performance. This is true whether one is talking about stereos, photography, cars or sports equipment, etc. And we also can't forget the pride of ownership angle (i.e., snob appeal) that comes from owning fancy and expensive gear. Plus, some stuff is just more fun to look at than other things. |
One more thought regarding the "appearance" angle. I had a client some years back whose only products were high-end writing pens. Their cheapest pen was $3,000, and their most expensive cost $85,000. I don't think the pens wrote any better than what you could buy at Office Depot for a fraction of that, but their main use was as jewelry for men. Think about it, jewelry serves no practical purpose other than appearance, yet people are willing to send thousands, tens of thousands or even millions on it. In audio gear, there is always the sound quality issue, but it doesn't stand there by itself. Just as with jewelry, one can run up the price of a stereo component with what it takes to attain a certain appearance. And that is without even discussing how the price tag can also be arbitrarily inflated just because of the brand name. |
I ordered 2 more A-07 amps for a surround sound, because they sounded so good (like neutral).
Some believe that the speakers make more of a difference than the amp. It is a pretty decent amp. And it’s really good for $70. Itis certainly better than no amplifier, and makes music just fine if the speakers do not have a wildly difficult impedance to drive. To me it makes a lot of sense to use that amp and a decent speaker and preamp if one is on a budget… and maybe even if one is not on a budget. |
The thing is that the Maganepan LRS are low impedence and hard to drive as we all know. Many Receivers and integrated amps cant even drive them. The ayima class D chip can double its power from to 4ohms, its only 40watts. I am not sure about the quality of the Ayimas build. I dont trust the power supply, probably very cheap as other have commented, which lead me to wonder how good are the Hypex Nc502 modules for $750. Maybe others can chime in with their experience. I know class D can sound sterile, not reccomended! The usual suspects are Bryston, Parasounsd, Schitt Vidar,Odyseey, Pass XA25 and even high current tube. What other opitions ? |
With the A-07 one uses more or less voltage in the form of the SMPS to get higher wattage. |
@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. 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. |
