How does a Transport effect sound?

Actually a neglected part of the audio chain between Syncromesh and DAC is the quality of cable you use. Firstly - always go for BNC. This is  unequivocally a superior connector, 

A friend brought around a Shunyata BNC 75 ohm BNC SIGMA. Now this is a very expensive BNC - $2500 USD.

I have to say that the syncro mesh performance has jumped up to a staggering level. The added dimension has a nuance that is hard to explain – truly off the charts. Goes to show how good your unit is. The SIGMA BNC brings additional detail and layers that I have seldom heard on any rig any price. I have a lessloss Cmark power cable (new Litz wire config) feeding a Sbooster which has a Furutech NCF riser EMF/dampening system supporting the SM. Feeder is an Argento Serenity Reference silver SPDIF cable. Youtube HD material rivals my NAGRA CD player now by a comfortable margin.

I haven't tried Steve's reference cable nor the Hynes Dynamo power supply. Not sure how it compares to the SBooster but I can say that the Shunyata shows how good this unit really is. 

Here is the lesson for me - often we look to upgrade equipment to the next level but unless you optimise the chain - you dont know what you really have in your hands. 

Firstly - always go for BNC. This is unequivocally a superior connector,

In comparison to what?

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

RCA obviously. It cannot be terminated properly to any coax.

Steve, your opinion (or fact) on this please....

As you know, in my case I’m going Oppo>Yggy via **RCA** coax out from Oppo and in to Yggy. Shame on me perhaps, but other than optical this is my only option. Or is it? :)

Question given the aforementioned....

Technically I could go RCA coax out from Oppo and terminate with BNC coax in to Yggy. So is RCA>BNC coax "better" than RCA>RCA coax? (same coax and all else equal)

Thanks.
