I also have a question for unit owners. How many days for burning in of this unit to get sound stabilised?
Well, I just played my music for a few hours a day (whilst listening

Of course this could just be my ears adapting to the sound...

Anyone running the HD-DAC1 with the Sony MDR-Z7?
Also, so can you hook up a USB drive and operate it like a music server with the remote? Without a computer?
I suspect its more down to the head out than the dac section, once you get to try it with a stand alone amp you might be able to confirm this. At least that's how I find my Marantz network player which is the NA7004. There is a lot of micro detail lost through the head out. Its actually not to bad a head out if your running mid fi phones as they don't dig as deep as the totl cans do so you don't really notice the short comings. With the dac feeding my Bottlehead Sex amp its a different story lots of detail and textures to instruments and voices good density of tone etc etc. I brought the NA7004 specifically because its dac section was said to be out of the Marantz KI Pearl a £2400 reference CD player which had some great reviews at the time. I would expect the dac section in the HD-DAC1 to be of a higher ability compared to the older NA7004 .
Looking forward to further views

Hello all.
For general reference, I took home a HD DAC 1 on trial on Wednesday. It ran hot, hummed a little and suffered serious RF interference on the front IOS USB input. I read elsewhere online of experiences of some faulty units.
On return to my brilliant local supplier today they found their demo unit also demonstrated RF interference (albeit a lot less) with a lower ohm headphone (B&O H6) and so they are going to contact Marantz to obtain a (silver) unit that works (!).
This is all very frustrating as otherwise the unit is wonderful, especially with HD800, so I am hoping they can procure one that works properly. I will report back accordingly,
Best

Disappointed to learn about the humming issue. Hopefully Marantz will have it sorted out in a new revision. Can any of you compare the HD-DAC1 against offerings from Audio GD for the HD800? I was hoping to find a good amp/dac combo that was detailed but not too fatiguing for the HD800. The Cirrus Logic dac in the HD-DAC1 is what initially attracted me to it.
