I purchased the HDM-03 from JFDigital. As a matter of fact the firmware used on the HDM-03 is very similiar to the firmware used on the Opera Consonance D-linear7. I love this streamer because it's simple. I can see my music shares the way I structured it on my NAS using "Asset" UPNP.
The player has XLR output and two sets of RCA outputs so I have XLR cables going to my Quad 12L Actives and just one RCA cable going from the left channel of the HDM-03 to the REL Sub's LFE. My system is simple but sounds wonderful, I was just wondering if I could fine tune the REL even better with some input from the forum.
I did a bank to bank wire transfer to pay for the HDM-03 and they shipped it to my home. I recently order one for my brother since I had already went through the whole bank wire procedure which can sometime be frustrating but it was
worth it. JFDigital is an upstart company but I think for the price vs performance you can't find anything to beat the HDM-03. I'm waiting to see what my brother thinks of the streamer because he has more audiophile experience then me.

By the way I had a Monarchy NM25 DAC with matched Amperex 6922 Tube because I like warm sound but I've since took it out of my system because the Wolfson chips in the HDM-03 are warm enough for me.
