How does a Transport effect sound?

In theory at least,  bnc rca should be superior to rca but inferior to aes/ebu. 

With the PS Direct Stream player/dac combo I reallly have no more use for these devices.

+1, ozzy.
With a good transport/dac combo, such devices won't do much to improve SQ.

While the Lyngdorf 2170 is good in its category of products, it may not be considered to be a true separate dac in the strictest sense of the word. Given the topology of the 2170, it is to be expected that the SM would significantly improve its SQ in spades. :)

aniwolfe,

In any transport/dac combo, beyond a certain threshold of quality, the SM may not improve SQ significantly when inserted between the combo. This can be easily verified with listening comparisons for any given combo.

aniwolfe,

I don't intend to given ozzy's experience. :)
