post #991 of 1153

Thanks for the answers. I figured that was the case but wanted to make sure. I might have to think twice about getting the D4. Although I could just use the D4 as a dac/amp for my netbook since I already do have a portable amp.

The nice thing about the D4 is that you don't need a battery in it while it's plugged in via USB.  You can keep your 9v's charged until needed.  When it's time to go portable, pop a battery in and be on your way.

I'd still have to get one of those 9v chargers. I wish it just had a battery inside that was rechargeable like how the mini3 is but I guess I can't have it all. I'd like to have the option of using the amp if I wanted to but I do have a much smaller amp and I probably wouldn't like carrying around such bulk for portable use which is why I sold all my portable amps until I bought the T3 which is much smaller. I'll have to see over the next couple days :P It would kinda be a waste if I just got these as a dac/amp for my netbook.

How often do you plan on taking it with you?  Mine will hardly ever leave my desk and if I choose to go portable, I can just grab a 9V at the corner store and be good for the day.  I've even put rubber feet on mine as it's main duty will be as my desktop DAC/Amp. I like having the option of portability, but that wasn't my main reason to purchase it. I will say this, coming from the PA2V2 it was a nice step up and the USB DAC is fantastic.

I would use it with my netbook quite often. I have a transportable dac/amp already but I'd prefer something a bit smaller but I'm not against just keeping it since it still is much smaller than any home component. If only there was something with my current dac/amp sound in the case of an uDAC smily_headphones1.gif I just don't like the thought of buying the D4 and then having to recharge batteries by taking them out and then using a charger.

If you mostly use the D4 with your netbook via USB, the battery issue is moot, as the D4 will  be powered by the USB input for the DAC and amp functions if enabled by the power switch on the back.

It's not moot if you are trying to drive an HD600/800 or HE-5 LE which benefit a good bit from the extra power of the battery, even when plugged in via USB as a DAC/amp.  Where the 5v D10 would be a little underpowered driving these phones, the D4 gets a nitrous boost by flipping the switch to 9v.

Ahh, nitrous. Nice to have the option. Kind of cool in a way. Good sound either way but yes, the HD600 series does benefit from the 9 volts.

I'd just like to thank you all again for helping me choose the D4.  I've been running it every day since it arrived and to say I'm pleased is an understatement.  I've been using it mostly as my desktop solution: Foobar2k - USB - D4 - IEM's. The USB DAC is as excellent as everyone described and there's no hiss whatsoever. The amp has tightened up my W3's, revealing a bit more detail throughout and they've never sounded better.  I'm almost ready to start rolling the opamps to see what else I can coax out of the D4 sound wise.  Ron, you'll be hearing from me.

I saw some questions about if you could power the D4 with USB and still use it as an amp for line-in amplification. I had some problems doing this when hooked up to a computer, but I'm pleased to note that if you plug the D4 into a USB power adapter with no computer on it (so power only) the line in/out port functions as line in and lets you power the amp using the USB power.

 

Handy and cheaper for saving on batteries when you don't need the extra 4 volts.

I have the latest version, (2 weeks old) and mine works off of the USB from my PC.  It has been plugged in via USB since I got it and I've used the LOD out of my iPhone with it with no problems.  It's very convenient.

if the power is straight from the usb, how is the sound compared to running off battery (assume using d4 as DAC from usb)? i heard that usb gives off a max of only 5V. im really interested in either a d4 or d12. having a really hard time to pick. i dont really care too much about portability since i will mainly use it off my laptop. just that i will probably take it to work, school, comp lab, home, etc. headphone it needs to power is hd600. thanks

Even with 5v power, both the D4 and D10/12 sound excellent and can easily power most phones to a satisfying level without distortion or clipping. 

post #1004 of 1153

I always use 9v battery on my D4 when powering my Alessandro MS Pro.  The D4 sounds less rich and less full running off usb. It is audiable especially on the voices, it sounds a bit shrill compared to the more open and fuller presentation of the amp powered by 9v.  With my iem(UM3x) it sounds the same 5v or 9v.

Agreed. No difference in sound whatsoever with my d2000's (though I concede that these are efficient cans)
