Jitter output is one variable in transports that can make a sonic difference. As to how much jitter the Krell puts out, who knows. Another transport, dedicated or not, could be better or worse.
Another variable is what digital out/in your transport/DAC is optimized for. For example my Proceed transport is optimized for AES/EBU output, my DAC optimized for I2S input, I should attain maximum sonic quality using a transport optimized for I2S with my DAC, or I could get a DAC optimized for IES/EBU.
