@@user-pq7vh5ob7p , Look thru my other Music Demo Video’s and you’ll see I don’t favor any one Amplifier more than the other because all perform differently..The difference is in power, DAC or added features As there’s a big difference between a streaming Amp/DAC than just an Amplifier with no streamer.. It’s entirely up to each individual that hears each which one they might prefer ..But the AO300’s DAC sounds better to my 70 yr. old ears👍 And the AO300 with 165 watts has much more headroom than the Wiim AMP.. Try them both thru Amazon & the one that doesn’t suit your Ears, send it back👍 Easy Peasy❤️ Best2You..I also have lots more Amplifiers , Speakers & DAC’s I’ve never uploaded to KZfaq..
