@rusnak666 - The Mullard 6080 and RCA6080WA are good tubes, the Mullard having the most balanced sound. However, I find that synergy between the power and preamp tube matters a great deal as well. Mix and match and see what you like. As Volly rightfully said, it depends a lot on your taste...

Yes, it does.

I can highly recommend the Maveric Audio TubeMagic A1 - it sounds sublime as a head amp! Huge improvement over the NFB-15. (I had mine connected as you intend doing) 

Awesome! Looking forward to reading your views. A friend of mine likes his NFB15 much more than his Schiit Bitfrost :) Mine took about 7 days from China to SA.

I have had mine for approximately 8 months now, no regrets in getting it and no issues. I have the transformer / TCXO upgrades.  I like it very much and i will probably stay in my setup for a very long time. Build quality is superb. Sound, as a DAC is wonderful. In my opinion better than my...

+100   Get the upgrades as well. (BNC not on my list)

Thank you - done :) Hope it solves my Windows volume problem...

I just got my DAC and have the same problem. I am using  Windows 8 & JRiver and have to set the audio device in JRiver to "Direct Sound" and either "Application Volume" or "Internal Volume" (Inconsistent glitch)  to get Windows to manage my volume. I do not like the sound quality in DS mode and...

OK, I am not going crazy yet. Just rebooted the PC to try another DAC and "Application Volume" does not work now. What works now is "Internal Volume"  What???? 

Thanks for all the help guys. Finally have it sorted. Settings as follows. Perhaps it will help someone else with the same issue in the future. I am convinced this did not want to work yesterday, but anyway, I am very glad I now have a functioning volume control again...   JRiver selected my...

I have the pc and dac connected via USB cable.I have tried optical as well, but same problem. I have tried system volume, unfortunately it does not work.

Thanks, but I still would like to control the volume with windows. It's my remote control.    Help!!!

Yes, the Audio-gd DAC is selected in Windows playback devices. (and same in JRiver)

Please help. Just received this amazing DAC, but cannot get Windows volume or JRiver to adjust the volume. Only turning the physical knob on the DAC allows me to adjust volume.   I have tried using different audio devices within JRiver (Direct-sound/Asio/WASAPI/Kernel) but none of them allows...

I am looking for a DAC to replace the Asus Xonar Essence STX. I am undecided between the Maverick Tubemagic D2 and the Audio-gd NFB-15. They both have pro's and con's for me, but I am more concerned about the sound signature of these units being used as DAC's only. Are they similar sounding or...

Nothing wrong with the card. It's normal. The sound it makes is like a relay switching.

Have you bought your gear yet? Let us know what you think of your kit when you get it.   I have the Sennheiser Momentum on-ear headphones and I must say they are great cans for just about any genre of music. Bass is great, but not loaded or bloated. Being low impedance phones they are very...

    ^^^^^ Bump... .... anyone? I also would like to know the answer to this one?

I already have a DAC, the Asus Xonar STX. I don't really need a speaker amp, but seems like it's a good headphone amp with a speaker amp as a bonus. I am certainly going to hook it up to my speakers and see how she performs. Will keep you guys posted on the results :)

Thanks for all your help PurpleAngel I decided to increase my budget a bit and went for the Maverick A1 Hybrid tube amp http://www.mav-audio.com/base/product/tube_magic_a1 It got many good reviews and seems pretty decent piece of kit - also being able to drive my cans. I hope I made the right...

Thanks for the reply and info! Much appreciated! I have an STX and just got the Momentums, so I was wondering if I am missing out on quality. To me it sounds pretty good, but I've read that the STX is not so good with low Ω HP's (as you said here as well) Having said that, would I benefit from a...

Hi. I am new to HP-fi. I have a pair of Sennheiser Momentum On Ear cans and are wondering how this amp will work with them? The Momentums are 18Ω

Is the Asus Xonar STX and Sennheiser Momentum (On Ear) a good match?   I read that the Xonar STX performs poorly with low impedance headphones. The Momentum cans are only 18 ohms.
