Hi. trying to decide which YJ model to get:
Yuan Jing Audio - TPA3116D Class-D 2.1 Stereo Amplifier [50W x 2] + Sub-Woofer [100W] + Audio Tuning - USD $53.50
Yuan Jing Audio - TPA3116+AK4490 2.1 Bluetooth Digital Amplifier - USD $83.47
Yuan Jing Audio - TPA3116D Class-D 2.1 Stereo Amplifier [50W x 2] + Sub-Woofer [100W] + Audio Tuning + Bluetooth [Blue Version] - USD $58.20

I see the blue version has 2x more large purple caps than the ak4490 BT ext DAC version. Which is better regarding power/bass note wise?

Which has lower noise floor?

Which has longest life/best caps?

I personally won’t be using bluetooth, only rca input. friends might use bluetooth input.

Or do you have other make/model you would like to suggest? 🙂

Know of any 2.1 boards using tpa3255 being sold soon? I’ve not found one.

...tpa3255...amp is ready

my suggestion is that this amp has weak caps but if you have a very strong psu i might not be a problem if you do not think that you need more than 60 - 100W per channel.
and i do not need bluetooth....you too...so why not just a tpa3255 board...?

What is you overall budget for your amp?

budget is around £50 for tpa3116 2.1 amp. for tpa3250, up to £100 but prefer £50-£80. Willing to spend a bit more for 3e-audio quality. As i like what they make a lot. I also wanted a finished product. I’ve worked with a lot of amp boards. So something ready made would be nice change.

I am using dc-dc converters to power them. i can splash on another Sure 300w boost for a over killl but plenty of margin power supply or if i can find a half decent 150w-200W boost converter. Maybe i add a extra large cap on dc-dc convert output 🙂 ?

Don’t remember seeing that YJ 2.1 tpa3255 before. is it good? noisy? Some what over powered for 50w speakers
