Of course, yes. But I'd tell you some other thoughts that you might don't think of.
"Deeper bass" or "wider sound stage" don't always mean "better quality". It's our brain that "explains" the differences such a way. People tend to like some distortions, and, because they like them, they think about them in positive terms. Nobody who prefer tube amps express like "I love those even harmonic distortions!". Instead, they speak about tone balance, sound stage etc.
Back to DX90. It utilizes balanced current outputs from the DAC. Balanced outputs mean there are wires with inverted left and right channel signals. So, if, under some conditions, there is a crosstalk between inverted left and direct right, or/and vise versa, which words would be used to explain the result? I bet it is "wider sound stage" and not "crosstalk on balanced outputs", because stereo width controller acts exactly the same way
On the other hand, it can be crosstalk between left and right channels somewhere further in the path, and this crosstalk may depend on some conditions as well.
So, when you notice sound difference in sound stage, how to tell what is the reason: less/more crosstalk on balanced outputs, or more/less crosstalk on unbalanced paths? In other words, is it a distortion or an improvement?
In everyday life, I don't care. I prefer to listen to music, not to hardware, firmware, formats...
For many years, listening to the same records, from different sources, in different quality, on different hardware, I trained my brain to search for similarities, and this way to tune my internal DSP to compensate all those differences. The quality of hardware used I feel as a level of tiredness (load on DSP). Same with the quality of records. With a new hardware, I need some time to listen to a number of tracks I'm familiar with from the previous experience. Then I can enjoy listening new music on the new device.
It does not mean I can't hear differences. It means I don't concentrate on them without a real need. Frankly... I listen DX90 on my trip from home to office at mornings, and back at evenings. And every day, when I turn the player on at the evening, I do notice that sound stage is wider and bass is deeper than they were at the morning. But I don't care about the reasons and I'm not dissatisfied the next morning
I pity those who waste the time seeking for differences, which always can be found!
