Aball,
The two Jolida JD-100s I tested had stock and Svetlana tubes. I know from reading the threads these aren't necessarily the best, but I took that into consideration in comparing the player to the D1. I had the Sim here at the same time and the while I thought the Sim performed better, their sound is quite different.
I have to say it was tempting to keep the Jolida with the D1 as it made a great transport. Unfortunately the Alesis popped up and I had to grab it as in the end computer playback and HD recording/storage are where I'm heading.
Why don't you try the Jolida with a D1. I'm sure you can work out a deal where it's returnable, if not it's easily sellable. I'd be interested in your opinion on it.
