Some DACs I am Considering-Any thoughts?

Soekris 2541                $1.1

Doge 7                         $1.2

Mhdt Pagoda               $1.4

Denafrips Pontus         $1.8

Audio Mirror SE           $2.5

Holo Audio Spring 2    $2.7

Audio Note 4.1 Kit       $3.6

Lampizator Amber 3    $3.8

Anyone who can speak from experience  about comparisons
between any two these?

I like the use of a tube and I like the R2R style of build.

Prefer to stay under $2.5 but might be swayed.

Thanks in advance for sharing.

(Some of these prices are certainly not correct)
