I have modified both TI 3255 and Infineon Merus 12070 amps. They are alike yet very different. I keep the Infineon under my bed, secondary system and the 3255 in my main system. The SMSL with Infineon has several electrolytic coupling caps that cause that congested sound. After upgrading to proper PP caps it sounds a whole lot better. The sound adjustments can help in certain situations but it sounds better without them. And it is not as powerful as the TI, by far. And you can't do anything about it because the PS is internal. It does not need a DAC chip but it does need to convert PCM to PWM signal. So it stays digital, but a totally different kind. And you lose just as much as dac conversion. I have a pair of Fosi ZA3's and Ayima A70 mono's, both TI 3255. They don't need coupling caps and upgrading the $0.50 opamps for Sparkos makes a big difference, lifting them to true audiophile territory. I have put my 300b tubeamp and $5k transistor amp back in the box. Yes, they are that good. And they have substantially more power than you can upgrade with a heavier PS from 32V to 48V5A or 10A to fully use their potential. The Ayima has only 1 opamp and sounds a little less powerful than the Fosi ZA3's. But Fosi can be upgraded with 1 opamp per side. Also I think a sub out is far more useful that tone control for audiophile systems. I use a Laiv Harmony dac and a 3 arm vinyl setup. The mono's are fully capable of getting the best from the Laiv. I know because vinyl beats it handsomely.
The Topping TP-RA3 was my choice for a Class D setup, offering super-clean performance, excellent power, and great channel separation. The setup includes two TP-RA3 amplifiers and an Xkitz XOVER-3B active crossover, with one RA3 dedicated to the highs and the other to the mids.
I keep a class d amp in my house just to sound test different speakers. I’m not a fan. However, RSL, known for their subwoofers, has a neat little class d amp for $100. Tone ctrls, sub out, dac, and a cool bypass switch for sub woofer frequency control.
@ yeah, I’m not sure how all that gizmo stuff works. I probably misspoke with my description. That switch does filter out some bass to the speakers - I guess to take some load off the speakers when a sub is used. But it’s a cool little amp. It really shines with good speakers. Even the small speakers RSL makes are okay, but really good with their 10E SUB. A nice sound for cheap. My son lives in the dorms at Barksdale Air Force base and gets lots of compliments. I’ve been using their speakers for surround duty. A really good company to do business with.
my research I found that smsl a300 and ao200 is a lot better. I hear smsl ao300 is good and comes with sabor dac. I made a few shorts sound demo of Geshelli dac playing through my monitors with decent quality sound and different genres, I think I am the first one to make Geshelli sound demo with sparkos and akm4499 chip
I waiting 2 Fosi za3 to pair with my Topping DX9 or DX3 Also bought SA-200 op amp from Aliexpress and Vivid v7 from Burson The SA-200 I couldn’t find any reviews. But it’s a fully discrete op amp. Maybe it goes in the XLR inputs
I'm looking for the warmest cheap amp. I thought maybe the Fosi V3 with the SMSL SU-1. But I'm also considering the much more expensive Denon PMA-600NE. I need to power my new Wharfedale Diamond 220 in a small, very bright room in my little apartment, and I have tinnitus, so I'm very sensitive to sibilant treble. I wonder if the sound signature of the Ayima A70 isn't pretty much the same as the Fosi V3? Personally, I don't need an amp for anything but playing music from my PC.
Maybe consider a class A amp as class d isn’t normally considered to be to be warm. Or you might consider a tube preamp with a class d amp to tame the highs, and give a more realistic soundstage.
@@unewb Thank you @unewb. Actually, I already have a three-year old Fost T20 Tube Headphone Amp. However, I don't know if I could use the speaker aux out in order to hook it up to a Fosi V3 or not. Would that work, or would I need to buy something like the Fosi P3 Tube PreAmp?
I'd take the V3 Monos over the A70 if you want a warmer/smoother sound. The ZA3 is also a good choice if you want one amp instead of two. If your tube amp has a preamp output, you can definitely use it before the power amp/integrated amp to add some extra tube colouration.
You're putting out more content than it's worth. I hope you have some passive income to support this rather fruitless endeavor. Pretty sure you also put out a video saying you're quitting, but you never even slowed down. Loads of youtubers make "i quit" videos and then keep going. Odd behavior.

I love mine. The switch, however, is to engage a high-pass filter for the speakers. It does not affect the sub/pre output in any way whatsoever.

I haven't heard of that one, but it would be interesting to try
@ Give a try. I has a great price. Horizontal and vertical design
I just bought in this 11.11 sale and I’m waiting for it
