the signature 30 is a limited speaker just like the signaure 25.
if you like the sound of the ss25, you sure will like the s30's.
it is a very detailed transparent speaker.
it use pure silver masive wires from terminals to the units.
there are no printboards inside this speaker and therefore uses a wooden board with all components attached and connected with the very same masive silver wire.
when connected to good equipment and the right cable, these speakers will sound breathtaking!
if you like the sound of the ss25, you shore like the sound of these babys.
i use classé components and siltech g7 speaker wires and interconnects.
do not use ofc copper cables with these speakers, they can sound harsh in the mids, hights and to much bass.
Note: not everybody likes the sound of the signature range.
I personally like the sound of the folowing speakers:
-silver signature 25 prefered
-signature 30 prefered
-signature 800
signature diamond prefered
Prefered: like the sound of 2way speakers.
Even after all these years these speakers still sound up to date.
