Hello guys. i'm looking for a aforable amplifier with spidf input.
max budget- 120€
i found this 2 guys. can someone tell me wich could be better?
pretty same "chinese specs" these are the differnces.
AIYIMA D05
Chips set: CM6642, TAS5508, TAS5352A, QCC3008, CS8422, WM8782
SNR(Singal noise rate): ≥105dB
output power: 120W+120W 4Ω
AIYIMA D03
Chipset:CS8422+QCC3034+SA9123I+TAS5548+TAS5624+PCM1808+DRV603
Signal to noise ratio: 93db
Output power: 150W*2 4Ω
all we know that these outpout power are not "real". could be te SNR also "chinese SNR"? could be the D05 better?
also it says this on the specs. i don't know what really means ¬¬
thanks.

The chipset used in the D05 is now obsolete according the Texas Instruments who make the chips.
Just received my D03 today in the UK from China. Fast shipping and first impressions are very positive just using my iPhone as a source over Bluetooth.
I think you may find that the D05 units being sold are just old stock and the D03 is the current model and in my opinion probably has a better architecture build on a more recent chipset.

This is basically a finished amplifier so there is not much room for DIY.
Most of the circuitry is digital so the only areas you might want to play would be round the main power supply capacitor. Possible upgrading the capacitor or just bypassing the existing capacitor with some 10uF and .1uF good quality caps.

Colleagues, I am a little confused when choosing between D03 and D05.
On Ali's website there is a photo of the amplifier boards, so it seems that the D05 has better equipment and board quality.
And the amplifier chip is newer in the D03.
Most likely, the Chinese are cheating and the newer version D05.
Guys, what amplifier chip is installed in D03 and does D03 support APTX HD?

The D03 uses the Ti TAS5624A chip (TAS5624A data sheet, product information and support | TI.com)
The BT chip, QCC3034, supports ACC SBC APT-X and APT-X LL & APTX-HD.

I don't have one to disassemble, so I looked at the Ti, Qualcom websites and here:
