I'm looking at purchasing an amp to connect the TV to some speakers and found this brand https://goo.gl/uKDxQv - I just wondered whether anyone had come across this brand/model.

Thanks

It really depends on your speakers... It looks like a typical ‘class t’ amp with a Bluetooth receiver built in. I have a similar Topping 30w amp. Paired with decent bookshelf speakers it sounds excellent.

https://www.alibaba.com/product-detail/Audio-Power-Bluetooth-Amplifier-with-Optical_60133796688.html - looks the same.

Dont be fooled by the promise of digital on these, they all seem to just use a generic cheap bluetooth chipset, analog from that into a class D amp chip, some are noisy as anything since they dont do their analog design right, and the DAC in the bluetooth chipsets isnt always that good compared to an external one.

It might be done better since they have a optical input on it as well, usually the bluetooth reciever is the CPU for controlling everything on them, so still possible to be terrible even with optical in and a proper DAC for that.

With gear like that, from manufacturers like that... you are simply rolling the dice.

It's a simple 'buy a box from China and put your 'brand' on it'.

There's no guarantee it will sound any good, but it is cheap.

The optical won't handle Dolby or DTS audio either, so make sure that none of your content is encoded as such... Netflix through a Panasonic TV as an example.

Ended up buying a AV:Link STA40-BT (https://goo.gl/RZEYCy) from surplustronics and I'm happy with its performance.

Thanks for all the advice.

Cheers
