For those of you that had to return equipment to audio-gd, what address did you ship to? I've had my NFB-12 and T1 sitting in a box unable to use either for a few months now and I want to get around to shipping it, but the user pays shipping both ways and the mess of a shipping address Audio-gd...

Well, it seems to be a blown power supply because that's where the extreme temperatures were originating from. I opened it up to check out the internals and let it cool off for awhile. It turns on, but with it set to High gain it shuts off the power LED and the output has buzzing in it, then...

I didn't leave my home for a period of 2 days, no. I listen to music or otherwise use audio output at all times when I'm at home, yes. How do I get food? From my fridge. Why would I turn off the amp going to the fridge? I only go grocery shopping once every couple weeks. I saw the sun this...

I'm not using my headphones on while I'm sleeping. I'm using it as a DAC to my powered speakers which plays music that I fall asleep to, then when I get up I turn off the speakers and use the headphone output.

The problem is that I'm using it while I sleep, as in I'm listening to music then fall asleep with it on. Then immediately when I'm up in the morning, I'm using it again, so it doesn't get a period to rest.

The complaints about the heat of the NFB-12 seem to be legitimate. I left mine on for about 2 days (listening to music while I'm sleeping, listening to it while I'm awake), and suddenly it powered off. Touching the top of the unit was nuclear, too hot to touch. I think it has a bad power...

Looks like my pair crapped out again exactly the same as I sent it in for a few months ago, it's loose in the casing itself again and cuts sound in/out when I tap on it.   Just going to toss these things in the garbage. It was bad enough that when they repaired them the first time they came...

Quote:   Most people prefer the 8x Linear Phase Apodising filter, it's widely considered the best filter on the WM8741 DA chip. This will limit you to 48KHz output.   If you need 96KHz support, try 4x Linear Phase Soft-Knee filter, since the 4x Linear Phase Apodising filter isn't...

Interesting. I really like my T1 with my NFB-12, and even though my wallet is hurting right now, it's really tempting to pick up the NFB-10SE and go balanced. Will be watching this thread for awhile.

Depends on how sensitive/low impedance we're talking about. I still use high gain with reasonable volume levels on ATH-M50 and RE0, which are 32 and 64 ohm respectively. Maybe some sensitive 16-ohm IEMs - yeah, it could be a bit too much. On a side note on my T1 with low gain set, with volume...

When I'm using it as a DAC, I use high fixed output (12 o'clock) going to my tube amp, and use the tube amp at about 10'o clock with it also set to it's highest gain setting, when I'm using it's HP amp I still leave the gain on high and use about 10 o'clock. But this is using 600-Ohm T1. The...

You CAN adjust the filters on the old NFB-12 model, it requires lifting pins off the PCB for the WM8741chips. It's not even remotely as convenient, especially if you can't precisely solder it back on to try other settings. Before the new model was available with the filter adjustments, people...

On paper NFB-12 is over twice as powerful amp wise, and the DAC section should be better (dual wm8741 vs single wm8740) NFB-12 is also something like 2-3x the audinst MX-1's size however.

E7 has a lower grade DAC (single WM8740 vs dual WM8741 on NFB-12), and NFB-12's amplifier is roughly twice as powerful than the E9.

Littledot amps are made in china as well. Also, both the MKIII and NFB-12 get pretty toasty under normal use. Often I'll leave them both on for days at a time, and they've run for like half a year like this without any issue.

MKIII is just an amp, not a DAC. NFB-12 by itself is far, far superior than running the MKIII off onboard sound or something like a Xonar DX, from my own experience. NFB-12 + MKIII is indeed better than just the NFB-12, but remove the NFB-12 from the equation and it all falls apart.

Aren't the "Pro" version of DT990 250-Ohm though? They're easily one of the best pairs of headphones I've used for their cost (they're what made me buy the T1), but the 250-Ohm version didn't go loud enough on my laptop straight from headphone out, and things dramatically improved with a dac/amp.

Well, if you look around page 121 you'll see a bunch of people complaining about this exact thing happening to them, including mine. That's about a month before you got yours.

I think they had a bad batch or something, mine along with about half a dozen people within the same week reported this type of issue.

I wouldn't suggest RE0 for DnB and dubstep at all.

Both my tube amp and my nfb-12 get pretty hot, as a rule of thumb I just don't stack them and I leave about an inch of space between them for airflow. General temperatures seem to stay in check, even when it's hot in my room.

I think they would, since they seem to carry the same characteristics of the beyer house sound. I hope they release updated stop-gaps for DT880/DT990 as well, since the only thing up from those is the T1, which is really like a super DT880 more than DT990..

Well, adjusting the filtering reduces what samplerates are usable, if you use 8x oversampling you can't use 192khz or 96khz sampling rates. It's set to 2x oversampling for 192khz support to be available, but alot of people will prefer 8x oversampling which limits you to 48khz.

Earlier in the thread a user named supercurio had made the measurement that High gain should always be used, as setting low gain attenuates the signal. On his measurements, it was more like +0dB and -12dB gain rather than +12dB and +0dB gain, between High and Low settings. High Gain should be a...

Well I got my replacement RE0 back, looks like they repaired my existing ones instead of replacing them since they're all scuffed up from them taking them apart... not very impressed. Also just received a $31 duty fees bill in the mail just today from TNT, even though they declared the value...
