Upsampling/Advice on Transport

After reading Sam Tellig's piece in the Feb. stereophile, I've decided that I want to take the plunge into upsampling via the MSB Link DAC. Unfortunately, my current CD player (Sonic Frontiers SFCD-1) doesn't have digital outputs, and so I will need to get a transport. His article implies that the quality of the transport is virtually irrelevant (he even used a Radio Shack portable and got the same results), because part of his suggested system is a Monarchy Audio Digital Interface Processor, which acts as a jitter reducer. So here is my question: in order to get the best sound, do I need to spring for an expensive transport, or will any consumer-grade CD player with digital outputs do the trick. Opinions?

This is a fantastic thread with very good posts! I've learned a lot just reading through the responses. This is of great interest to me because I am considering upgrading my Musical Fidelity Elextra E60 CD player by adding an anti-jitter device like the Monarchy DIP and a Bel Canto DAC 1.1. One question though. Is the length of the digital cable as critical as I've heard some people say? I've heard that 1 meter is the absolute shortest run that can be used without adding too much jitter.

I am not a techie and so I do not understand why, but there is something about the length of the digital cable. I have tried a 1/2 meter and 1 meter lengths of identical brand digital cables and the 1/2 meter sounded worse-a little brighter and definitely grainier. I have read, although I can't rememeber where, that 1 and 1/2 meters would be the ideal minimum length for a digital cable.

Regarding your experience with varying lengths of digital cables, and their performance, I've lifted an excerpt from the FAQ page at the Bel Canto website as follows:

"NOTE: We suggest if you are using Toslink, make the toslink the longer cable and the RCA cables going to your preamp short. If you are using RCA type digital cable, make the digital cable short and the RCA’s cables going to your preamp longer."

It seems that your real world experience matches the advice given by Bel Canto. I am no techie either, but I have also heard the 1 1/2 meter length as being the minimum for a digital cable in order to avoid excess jitter. Interesting...
