Hey people, what might be the ultimate cheap upgrade over the Apple USB C - 3.5 mm dongle for a Grado SR60e user on the very tight budget? Adding a real simple amp or another ultimately cheap DAC? I mean real dirt cheap. He just showed me this;

This cable-DAC, as most do, uses a Realtek ALC5686 which is a cheap PC/phone/portable onboard chip. In theory it can provide 192 kHz and 45mW, but most companies build it ‘only‘ up to 24 bit/96 kHz. And connected to a phone I don’t think there is enough voltage to gain this power. 8-10 mW on Grados 32/38 Ohms appear more realistic.
Better build quality, no cable and good reviews has the ddHifi TC35B. But it raises the costs by 20 or 30 bucks. Back to 10.- to 20.- :
Some uses an Conexant CX21988 which is an alternative, for example ESR. There is also an CX21988-THX, that may raise the cost by 5.-, but I am not aware about a product where it is build in.
There is also the Cirrus Logic CS46L41 you can find it some chinese adapters made by (or for) JSAUX. They have ‘Hi-Fi Audio Pro‘ printing on the 3.5mm plug. Try ‘JSDENZC2AUXFHFGY‘ on Amazon.
If you want a really audible upgrade look for a Fiio E10 (old: WM8740, new: TI PCM5102). Round about 69.-. The next would be the dragonfly black by 99.- (ES9010).
Next, you reach the Wow!-zone with the Questyle M12 costing 129.- (ES9281 AC and Current Mode Amplification).
Some of the Fiio BTR* work with USB-C connected to Androids, but you need to try that with your stuff (AKM chips, Bluetooth, some with dual DAC (BTR5 (2021 model): dual ES9219 C), some with balanced amplification (BTR3(K)/5)).
Some of these cable thingies do not provide 32 bit or if they do, they do it only up to 96 kHz.
Most can’t handle DSD.
24/96 sounds better than the MQA (hyped) stuff. But 24/192 is even better.
Your SR60e really is a great headphone, a definitely ‘best bang for the bucks‘ thing.
It doesn‘t necessarily need, but it ‘s worth even much better amplification.
You will hear it.
