thanks for your reply!
I did a little bit of research and found some options. I prefer to spend less than 50$, but there are some other options above this price point. here is the list:
1.Breeze Audio TPA3116
2x50w / TPA3116 chip
2.Lepai LP-2020A+ (25$)
2x20w / TA2020-20 chip
3.SMSL SA-36A (50$)
2x20w / TDA7492PE chip
Second list:
1.Topping TP23 (70$) (amp/dac)
2x25w / TA2021B chip
2.Topping VX2 (75$) (amp/dac)
2x40w / STA326 chip
3.Topping TP22 (80$)
2x30w / TK2050 chip
4.Topping TP30-MARK2 (85$) (amp/dac)
2x20w / TA2024 chip
1.which one of the first 3 choices are better sounding?
2. if I get one of the pricier options (the next 4 items), would I get a noticeable upgrade?
Thanks in advance
