AptX support? If not, there are BT integrated amps (Grace Digital makes one) that support AptX, line in, a sub out and have similar power output into passive speakers. The grace I'm thinking of doesn't have USB in, though - the DAC only sees the BT input.
But the difference in sound for BT with aptx is striking.

Shenzhenaudio, the official distributor of SMSL products, says that the AD18 supports AptX. And an Amazon.co.UK reviewer (https://www.amazon.co.uk/product-reviews/B01M3ULDG9) confirms that it supports the 'low-latency' version of apt-X, so videos won't have noticeable lip-sync delay.

Good - with an aptx source and aptx receiver, the improvement is very nice.

I had contacted SMSL months ago before i bought this unit from AMZ. They confirmed that the Bluetooth codec was Apt-x. I had asked if it was apt-x HD, which they did not answer and i am assuming it is not, but with my phone (LG v20 - which has aptx-HD BT) it sounds quite decent for wireless sound. It also connects well and range is good. I like it a lot for the price. It easily powers my own custom-built 4-way tower monitors. Hope that helps just ask if you have another question! - tim

This is a very good question. Thanks for bringing this up. Judging from the responses I am happy to see the DROP community is very knowledgable. I am always amazed that, very rarely any reviews of BT gear (especially headphones) fale to mention which codecs are supported. But both paired devices should support the same codec (APT-X in this case). This is one of the key points which will determine listening quality. Here is a good site to check out which codec your phone supports: https://www.bluetoothcheck.com/ These reviewers who neglect to mention any of this should be called "charlatans" not audio experts.
