  I'm interested in this DAC, but have a quick question.
 
If I have powered speakers connected to the RCA out; and I plug-in headphones at the front port, the speakers aren't automatically muted? 
 
I have Sony's UDA-1 DAC, and that's the behaviour it does, when headphones are connected, the speakers are muted as it automatically switch modes. 

As Goldendarko said, it's rather unfortunate that this is not  automatic. I'm hoping they'll offer a setting option in a firmware update. For now, you have to use the mute on the remote, and hope you don't accidentally unmute and blow out your speakers.

Reading this thread has convinced me I "need" an HA-1 in my life.
 
Any recommendations on a USB cable that folks are finding works between a PC and the HA-1? I've seen a lot of posts about some USB cables being wonky, so I'd like to hear if there are specific cables people are using that work well with a PC.
 
Also, I'm going to be using it in a smallish room on a medium sized desk with a huge flatscreen monitor on it (34"). In terms of the heat that's been mentioned in a few posts, do y'all find the unit just gets hot itself, or does it radiate/blow a significant amount of ambient heat into the room as well from the vent? Trying to figure out a way it will fit on my desk, potentially with the vent directly behind the vertical flatscreen, and I don't want the heat to damage it. Unfortunately with a large-ish pair of Emotiva Airmotiv 5s active monitors on my desk as well, space is at a premium.

This is class A amp which generates heat all the time with vents on the front so for best results I would use thick extra pads under its feet and wouldn't put it under shelf on your desk where you have your monitor

It is rather unfortunate. It's unfortunate this isn't a more common behaviour; although this is what the "logical" expected behaviour.

Yeah, I definitely wouldn't be putting under a shelf. The monitor is pretty thin and is on an arm mount and has a lot of space under it, but I figure any extra heat rising directly underneath it probably won't be good for it. 
 
In the meantime, does anyone have any USB cable recommendations? Specifically, is anyone using a cheap Monoprice or Amazon USB cable with a PC without any issues?

Guys, when I plug in the phones, who don't the speakers automatically turn off?
 
This is kind of annoying having to unplug the speaker outs so that only the phones are playing.
 
Am i missing something?

You will probably be fine if using one of the higher quality high speed cables from Monoprice or Amazon as you mention.
Maybe just buy the best one Monoprice sells, which would still be pretty cheap.
I did buy THIS ONE last year for in my office and it works great.
Try to stay at the 6ft length if you can, since I think that is the sweet spot for USB to function at it's best.
I think when you get into the longer cables is where people start having some other issues.

Scroll back to the previous page.
Someone posted the answer that you have to manually mute the pre-amp function

  Yes, it is a good preamp but like this it is even better:
 

 
 

 
Using the headphone out to drive a power amp.

Very usefull information . Connected the  HA-1 to my Prima Luna Dialoque Premium this way (sounds great). Had to put in on high gain and +/- -3 db to get the same results as my cd player (in db's). Question(s): what settings do you use (when connected like this) and did you also try the balanced HP out for this (is that even possible?)? Are there more headfiers using the HA-1 like this?
 
Thanks in advance 

 
Btw totally enjoying the HA-1 PM2 combination 

 
PS pardon my english

I find that I have to turn the volume down a little compared to using the normal output on the back, about 3db. I think balanced is possible but your power amplifier also needs to be balanced. I would only attempt this if I was 100% sure about what I was doing. The single ended output is great so I am not tempted.
 
I have heard of others using the HA-1 like this.

I use the Cabledyne silver USB cable, 1.5 meters. Excellent sound and quality but more expensive than cheap USB cables. See this thread about USB cables: http://www.head-fi.org/t/703795/gah-audiophile-usb-cable.
 
As far as cooling you will need to have enough air space above the HA-1 for ventilation.

I use the TRS headphone out direct to my 300-B amp. Sounds much better than the OP-Amp RCA outs.

Hi,  
I am a Moon-Audio fan.  Drew knows cable, and I have been more than pleased with everything I have gotten from them.  Price-wise, I would say they are about in the middle as far as high end cable vendors go.  
 
I use the Blue Dragon USB cable from Moon....

Got the HA-1 today. Blown away by the build quality and how simple it was to set up with my PC. The drivers installed easily and are functioning without a hiccup.
 
The HA-1 itself sounds fantastic with both my powered monitors and my LCD-X. It was a significant step up in detail and transparency from my Sound Blaster X7, plus it just looks dead sexy.
 
So far it hasn't gotten too hot in about 2 hours of playing music. I've read elsewhere that it mainly heats up if you aren't using it to play anything while it's on. Very happy with the purchase. Well worth the price for the performance and functionality.
