Help: Differences Between Lumin Products

[nicoff]

I visited the Lumin website hoping to find a table that shows the differences between their different products and did not find it.
Can anyone here point me in the right direction of where to find such comparison or can someone here briefly explain the differences between the Lumin products?
It looks like all of them can do Roon, MQA, streaming services (Tidal, Spotify, TuneIn, etc.). So what are the major differences between the different products? Do the letters mean anything (U, D, T, etc.)?
Thanks!

Here is what I can gather from the website:
S1 -> Top of the Line; DAC can do DSD 128
A1 -> Same as S1 but DAC can only do DSD 64?
T1 -> Cheaper version of A1?
D1, D2 -> Same to A1 but limited digital outputs (no HDMI output)?
U1 -> No DAC

Still not sure if the letters mean anything or if those are the main differences.

I do not have DSD128 recordings so perhaps the A1 or T1 would be sufficient for my needs. Anyone here has compared the A1 to the T1?

S1 is top of the line with the sound quality being higher resolution and more neutral sound. Supports DSD128. S1 uses quad ESS9018 DAC chips.
A1 is warmer and more analog sounding.
T1 is a cheaper version of A1 with a less expensive chassis, but the electronics are the same.
D1 / D2 is the best selling Lumin. D2 is newer with an internal switched power supply. They do not have HDMI audio output.

A1 / T1 / D1 / D2 use dual WM8741 DAC chips.

Thanks!!
How does the sound of the D1/D2 compare to the A1/T1?
The same since using the same chips and design?
Thanks!

A1/T1 is warmer, more analog sounding and more dynamics. They come with a linear power supply and use Lundahl in the output stage. The circuit board is separated into digital and analog sections, with an aluminium shield in between for the A1.
