Best upgrade for SGC servers; LPS vs network switch

Not sure about their setups that claim thin sound, or what optical they are using. 

I am using this setup based on feedback here and at WBF. I have Innuos Zenith Mk3 with LessLoss Echo's End Dac with LL Fire Wire 640X. No this sound here also has a LPS for the Optical Converters. 

@sns you seem to be really high on these guys from Hong Kong at After Dark. ??

@sns well their products are made in Mylasia at least that is what the picture from the guys in Hong Kong are showing. I do not really care where it is made as long as it works...
