@tonyjack I was in the same boat. I own an old but very respected dac and was curious as to how dac has progressed over the years. I bought the Topping d90se to try. Well received and measured really well. Well getting right to the point, it sucked. It has high details but low transparency. in a sense that it allows you to hear almost everything. But it doesn’t differentiate pitch and loudness very well. So even though you can hear more instruments, those instruments sounded similar to each other and one song sound similar to the next. A monotone presentation that got boring very quickly. Soundstage was meh. Air was meh.
So yea the Topping was a disappointment. But I did like how vocals sounded on it though.
