Over the last 4 years or so I've been trying many DACs to achieve a sound quality that is natural and unforced. So many DACs in my opinion have a sharp, forced and highly etched quality to them that produces a very unnatural sound. I came across a CASEA DAC by accident by winning one of their older models on eBay. I was so surprised to find it so natural and relaxed I later bought their latest model from their website. For the money it is quite outstanding, beating all my friends DACs up to £4000 for naturalness and musicality. Spending more will give you a better sound but for £1500 direct from the manufacturer it is quite outstanding. The only limiting factor is it only has a USB input and won't do DSD or MQA, again for me this is not a problem because it sounds so good.
