I'm currently using the amp with my NFB-11 and it sounds great. Don't really feel like I need an upgrade anytime soon.

Thanks. For now I'll be using my NFB-11 DAC but will look into upgrading it later this year/next year.   By the way, just ordered the V200 from Thomann.de for 699€ (B-stock). Super excited right now. Can't wait for it to arrive.   Also, I am a bit confused about the pre-gain options in the...

Looking for a decent, fairly inexpensive DAC to go along with the V200 and Sennheiser HD 800 (SuperDupont mod). Would Schiit Bifrost do the job? Any other recommendations in the same price range?   Thanks in advance.

The buzzing noise persists even if nothing is plugged into the amp except the power cable and headphones. And the headphones work fine on other amps I own (O2, NFB-11)   The buzzing is weird though. It starts roughly at 8:30 and gets louder when you crank up the volume but disappears again...

Bought the Musical Paradise MP-301 MK3 tube amp and although it sounds great I'm having constant 'bzzzzzzz' sound coming from the left channel. The buzzing goes away only with very low or max/near max volume levels.   What I've tried:   - Changing tubes between the stock Chinese ones and my...

A question.   I'm very much interested in the K550s but I'm not sure if they'll be comfortable for me to use since I have rather large ears.   In comparison, I have the HE-400s with Focus pads and they just about fit around my ears but without much leeway.   Thanks in advance.

Thanks for this. Did the driver matching test, closed my eyes and listened hard and the sound was in the center throughout all the frequencies. So apparently the hardware is fine. The issue seems to be with the user.     EDIT: Tested with the HD800s. With the HE-400 there were some noticeable...

Well either it's just how certain songs are mixed or something wrong with my hearing or some psychological bs because I just tried it with my phone alone (to eliminate possible issues with MB and PSU or issues with sockets) and apart from reduction in SQ the volume levels sound identical to the...

Actually I just tested this using my phone as the dac and an O2 amp and it's the same way.   Yeah this is probably all in my head. Trying to find faults where there is none..

Yeah, but for example when I listen to the song above with the headphones the wrong way around I hear more emphasis on the left channel. Do you notice the same?

Got my HD800.             And they sound great imo. The bass is tight and the highs are crisp. And people who generally drive these with O2s and Modi/Magni combos seem to complain about the lack of bass and it's definitely not the case here. It's very much present and it's exquisite...

Yup. Ordered a pair of HD800s and the store has 14 day return policy for all headphones except IEMs. (for obvious reasons)   I'll try them out and if I don't like them I'll send them back. I'll write some impressions once I have them.

Actually one user on this thread seems to have both:   http://www.head-fi.org/t/624517/audio-gd-nfb-11-32-nfb-11-2014-delivery-impression-thread/30#post_8656859   Also, I have rather large ears and I really like the size and depth of those cans in the HD800. Would probably be a perfect fit...

How are the HD800s with the NFB-11? Sound wise and how well the amp drives them etc. Just thinking of maybe starting to save up for a pair.

Yup, figured as much. And like I said, it's not really a problem since I can only pick it up if it's dead silent (not listening anything) and I don't have any cans that require so much power to go over that threshold anyway.

From foobar? Yup. Currently using the ASIO: Via DirectKS ASIO setting from the output menu.   EDIT: removed the USB cable and and it still has the same hissing. So it's the amp right?

One question. Is it normal that when you crank the volume up past 2 o'clock in the NFB-11, there starts to be some level of background noise? Not exactly an issue since I'm not even close to maxing out the volume on my HD 650s. (stays mostly around 8-10)   Is it USB noise or noise from the amp? 

Actually I was getting bunch of issues like audio stuttering in gaming as well and all my problems were resolved by changing to another USB cable. No issues since last night. Will report back if I encounter any more but so far so good.

Well damn. It's been 2-3 hours without any issues now since I changed the USB cable. And before that it was constant issues. Spotify stopped playing music like 10 minutes apart and games had audio stutter. But now it's been.. Perfect.   I hope it was just a crap cable. Because I'm in love with...

Well I guess it's time to sell them or dabble with EQ.   But anyways, The HD650s sound incredible with the NFB-11 imo. Better low end and overall much "fuller" sound compared to O2. Not an expert thoug but that's just my impressions.   Also, I don't want to jinx it but the issues seemed to...

I thought they were required for Windows?

First I'll try another USB cable and see if it helps.   And yes, I like it a lot with the HD650s, but there's tons of sibilance withthe HE-400s. This might go away with time, right?

By the way, is there any difference between the different input methods in terms of SQ? I'm having so many issues with the USB drivers I was thinking of maybe trying OPT/Coaxial instead..

No, something's definitely still off. Was listening to Spotify and everything was working fine but then all of a sudden Spotify lost sound and couldn't get any sound from video files either.   Right now Windows sounds, foobar and Chrome work just fine. What the hell's going on? Are the drivers...

HA! Knew it!
