Any experiences with a Diyeden Great March II?

Thinking of getting an inexpensive DAC. Not convinced it will make much of a difference with my mp3/AAC/lossless files via Apple TV, when compared to the Apple's internal DAC. Maybe it will. For $300-$500 I'm willing to check it out. For $900, I'll pass.

In the $300-$500 family, a couple of DACs stand out, mostly for looks...the Diyeden Great March II, and the Musiland MD-10.

The MD-10 has a nice looking LCD screen, and apparently switchable inputs, but no upsampling.

The Great March II has XLRs out and upsampling but no discernable interface or controls. It is more expensive.

Can anyone shed some light on these 2?

I have used the Great March (not the II) modified by Pacific Valve & Electric. For the cost I thought the unit sounded very good as compared to the Behringer unit I was using. I have since moved on to a Paradisea + by MHDT Lab. Are you using USB? If you can I have found that to be the way to go.
Thx. The Apple TV only has optical out. There is a USB port, but it doesn't output audio.
Well hopefully within a week or so, I'll be able to address my own query. I have just ordered the Great March II.
Rkny, let us know how it sounds, I too have been curious about this dac. The one guy on head-fi who bought it said it sounded great but had a hum and the manual states that this dac needs a shielded PC and a conditioner! Power supply filtering might be it's shortcoming if this person is to be believed.
Well I got the Great March II. I'm still waiting for a pair of XLR ICs to make A/B testing possible between the GM and the Apple TV's DAC. But I have A/B'd between the Apple TV's HDMI out, going into my TV, then out to my preamp...not an ideal comparison I know, but prior to the DAC, I used RCAs out of the Apple TV to the preamp, and compared that to the RCAs out of the TV and the sound was marginally better. (I assume the TV has some sort of built in DAC).

Anyhow, compared to the TV's DAC, the GM II is pretty great. Slightly wider soundstage, increased dynamics, and definitely airier. I also somehow gained what to my unscientific ears seems like about .25-.5 db in gain. This of course makes a true A/B difficult.

My ears are not educated enough to comment on things like jitter...maybe someone could clue me into what I might listen for?

One thing I've noticed, which I attribute to the increased soundstage, is getting the crap scared out of me by random sounds that seem to be coming from way across the apartment, which are actually coming from the music. :)

From a build quality standpoint, the GM II leaves a bit to be desired. The cutout for the solitary front power rocker is roughly cut. Also, the unit was opened at the factory to install 110V (they come 220 by default I guess) and either the case is misaligned, or it was reassembled improperly. The feet do not rest flat, but rather there is a slight rocking action. There's also a slight visible gap at the casing seam on one corner. Also, the feet also did not come with any rubber or felt padding...they're just bare metal. A quick trip to Radio Shack solved the lack of pads and the rocking, but nonetheless, it doesn't say much about their QC or attention to detail.

I saw the complaints of a hum from that fellow on another forum. I am happy to report I have no such hum. At full volume with no signal, the unit is virtually silent, using the stock power cable.

Will report back again on sound quality when the XLRs arrive.
Ugh. Problems with this DAC.

The balanced Signal Cables arrived. When I use the balanced outs on the DAC to the balanced ins on my Rowland pre, I get about a -5db cut in volume as compared to using RCAs out. The sound via XLR also seems mushier and less dynamic, even if I turn it up. I can't imagine it's the cables.

Add to this a low but fairly loud hum when using the XLRs with the volume turned way up. No hum whatsoever with the RCAs.

Normally I wouldn't care, but I bought the cables specifically to take advantage of both the DAC's balanced outs and my preamps balanced ins.
Unfortunately, not every piece of audio gear with XLR connections is truly balanced (i.e., has fully floating ground with no reference to earth). I hope this is not the case with your gear.
I found this thread after seeing these are on sale. Hard to find much on this unit, so thanks for the feedback. I too was attracted to the balanced outs but I guess I'll pass.
looking at this unit. how do you switch inputs? is it auto sensing?
I own a Great March II and have A/B it to a Benchmark One and Matrox Mini DACs. I found the DAC to be warm and musical, highs are never too clinical. I prefer this DAC over the Matrix Mini. The Benchmark leads slightly in definition and presentation but not musicality. For $320 it is a wonderful DAC. I hope this helps.
