I bought the signum+ for utopias with adapters for susvara a few months ago
my recent impressions are that they sound better with the susvara than utopias
I was needing a bit more warmth with utopias. Almost like it was a little too disjointed in it's sound - a little too top heavy.
But I know others really like it.
And i don't fell 100% silver and utopias are my thing.
I am pretty happy with my heimdall 2 for my utopias
the signum+ were better with my susvaras.
they may further grow on me though i am looking for some more tone warmth to evolve for the susvaras
how do you find the palladiums vs the signum
ps i am right now using my silver draugs with my susvaras and yes they deliver well.
maybe my susvaras are "burning in" still as this pair arrived two months ago and I only burn in by using them.
Though that copper tone............... just brings out "that tone"...................
