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.
