Each dedicated music server I've owned has utterly outperformed any computer or laptop I've ever owned. Aurrender N100 ($3.6K), Aurlic Aries G2 ($5K), Aurender N10 ($10K), and Aurender W20SE ($22K) are a few examples. I discovered that the latter was so excellent that it was a great deal (I have related equipment to benefit from it).
I disagree with this because I switched from a dedicated PC that was stripped down for dedicated audio streaming to a Roon Nucleus (which, in my opinion, is just crap and way overpriced, especially when you open it up) and now to the Aurender A10, which, to be honest, isn't much better than the dedicated PC I was using before that was feeding a Schitt Gumby milti bit DAC. It is undoubtedly quieter and the background is darker, but (with the supposedly superb internal DAC) I feel that the high frequency detail and spatial Q's are lacking.
Utilizing Spendor D9.
There shouldn't be a perceptible roll off on the top end thanks to two very detailed speakers that are slightly tipped up at the top end (compared to other sources I have). At 57, I doubt I hear anything above 12k anymore, so I'm stating that.
I'm not saying the Aurender A10 isn't better overall, but it's not $8k better in my opinion (plus the interface is plain simpler on a computer). Before you buy, think carefully and use your ears rather than your eyes.
Before you take any action, you should also think about having your computer audio-optimized. It's possible that you won't need to update.
