CD Transport

The K1 Ruby has the same transport as the SA10?

I’m also considering a used CEC TL2N, opinion?

Here's an interesting article by Arthur Salvatore to the effect that the transport is more important to the overall presentation than the dac.  A minority view to be sure, but make of it what you will.

@leog2015 - I would definitely check with Audio Union before buying an expensive used CEC product.  I would give them the serial number to make sure it can be serviced if necessary.  I have never heard one, but the TL2N looks like a beautiful unit and I believe you can even add some type of outboard clock if you want.  

Tried to contact Audio Union, and it seems like they don’t have units in stock…

@leog2015  I believe Audio Union doesn’t sell anymore. They just distribute and repair. As I said above, I had a very good experience with Constantin at Atelier 13 Audio and I know they have the TL2. Maybe not in stock, as I think they order from Japan. But check if you’re so inclined.
