Do super thin solid core speaker cables sound any good? 

Interesting cables here. They are pretty much identical to DNM Reson resolution cables but branded Cyrus. They are solid core copper 1mm diameter, they use a wide spacing for super low capacitance and higher inductance, perfect for early exposure amps.
These things really do sound quite different to everything I’ve heard before. They have a almost calm sound to them, very clean and controlled with excellent timing. Bass is less but tighter with no overhang. Mids are neutral and highs are good too with no nasties. They sound is quite weird at first, music sounds different, open and nimble. When i change interconnects they allow a clear difference to be heard, when i swap to other cables i get more bass and warmth but at the expense of rhythm/timing and tightness.
