I enjoy them very much out of it. The stock power tubes are fine but I suggest upgrading the driver tubes to something else (to your preferred sound). I went with the KT88 power tubes for firm bold bottom end that your normally get with KT88.

I have my 2013 Deluxe and I am loving it. Plenty of power, no noise issues to report with all my full size headphones. I have upgraded the tubes and am running KT88 with some Slyvania 6SJ7GT (thanks Rob). I am impressed with it for the money. It looks well built and sounds pretty good. The dual...

still hoping they will ship the 2013 Deluxe version shortly...

ah crap, you are right. I saw the alps pot and didn't look for the relays!   I would say the power supply sections are comparable between the two, the NFB-10SE is listed as even a larger capacitance reserve.  The power supply is probably the most important part here. The schematic is the...

Are you talking hardware differences or ?   10SE has a full digital control interface and screen vs. 10WM with push button and pot volume control 10SE has digital relay controlled volume vs 10WM which has a potentiometer volume control 10SE allows you to select through 9 different DAC...

I would suggest the Lyr from personal experience if you plan on using unbalanced 1/4" (or 1/8").  If you plan on going with a full balanced setup I would suggest the LD MKVI+   My current setup has a source thats balanced and I would up enjoying the LD over the Lyr with my LCD-2 Rev1

What headphone are you using with it?   Quote:

http://vacuumtubes.net/RES%20Audio%20pages/5998.html 45 bucks a pop.  They were really nice the ones I got, very clean.

My favorite combo is Nos Tungsol 5998 power tubes and NOS Tungsol 6SL7GT (VT-229) BGRP driver tubes

Definitely do the drivers, 1/4" output was an afterthought.  Buy it if you want to run balanced headphones.

I can highly recommend the Audio-gd DAC/Amp combos.  NFB-10SE plus some 400+ dollar phones.  With that setup you can power anything with either 1/4" or 4-pin XLR terminations.   If not that I would try the Schiit Audio Asgard with a separate DAC and then a set of headphones.  That is a great...

I have compared the Yulong D100 and NFB-12 and thought the DAC sections were similar but the NFB-12 had more power. So I imagine the NFB-10SE to be better in all aspects then.    Build quality wise the Audio-gd was better.  The Yulong soldering was terrible and they left behind lots of flux...

No big deal really.  I talked to Billy from Hifiman and that is where I got my information after asking him about it.   Quote:  

Not sure that is their intention, it would totally change around the guts going from a SE to BAL setup internally.  I got the impressions that only the outward looking items (Case, buttons, etc) were to change.   When you get yours snap a pic of the insides of it at the back of the...

No, I meant the 4 pin output on the EF-6

FYI, it is not true balanced out.  - is tied to gnd.     Quote:  

Great showing today.  Pictures to come shortly.   Thanks to all the vendors that showed up and all the vendors/individuals who contributed to the auction.                                        ...

  All packed.

I used Dr. Beth Orliss for my molds and they came out perfect the first time.  I didn't have to send back my IEMs ever for a re-fit.  She did an excellent job.  If you are coming to the show and need impression don't skip out on letting her make them for you!   Quote:  

I pulled the power plugs to my fans and the noise in the 1/4" is all but gone.  I could hear a noise walking through in a cyclic rate (two fans operating at not quite exactly the same rpm).  Yep, most of my noise was the fans.  Unit is still cool, I know LD says you can run with out them in a...

I will also be bringing my Fostex T50RP w/840 pads and AH-D5000 so you can add those to the first post.

Anyone want me to bring along the NFB-12? I usually leave it at work.

I should be there with my Audio-gd NFB-10SE, LD MKVI+, PS Audio DLIII, LCD-2, and AH-D5000

I think he may be more hinting at where I was going. Some tones (consider pulses here too) have a faster leading and trailing edge transition depending on shape and duty cycle vs. others.  Square vs. triangular for example.  Square ideally is instantaneous but is limited to physics of the...
