audio-gd C-2 Class A
Oct 15, 2014 at 8:23 AM Post #63 of 141
The SA-31SE may have occupied the same place in the model hierarchy, but it was quite a different animal. A powerful (6W) Class AB design, AFAIK it was derived from a 1990s Accuphase circuit topology. It certainly has the "Japanese high end" sound signature...

It will drive HE-6s!

  I have the discontinued 10ES2.  I can't compare the amp with other dacs besides the built in sabre dac because there are no line inputs.  However, I feel that the balanced section has more pronounced slam and control to the sound compared to the single sided input.  It might seem a little bit brighter or more lively to some. There is good extension in both ends of the frequency spectrum.  It has no trouble driving HE-500 or any other planars including the HE-6(obviously not the best this can sound).  I would have bought the NFB 28 with line input but it came out about a month after I purchased mine.

Yea I too wish I'd gotten the NFB28, it's now at the same price the 10ES2 is... oh well. Ideally I'd like to grab the PCM Ref 10

  Headphones driven be a balanced setup of same amp circuit design (i.e. Master 9 vs C2 Class A) will have higher diaphragm speed and control. For high impedance headphones, the additional voltage swing available from a balanced amp is always welcome.
 
However, as most headphones manufacturers tuned their headphones in single ended configuration, I would always want to listen to headphones in the best possible single ended setup to appreciate the intended sound signature of the manufacturer, before going after the balanced option.

That's a good point, never thought of it that way. What do you think are some of the negatives of balanceing a headphone made to be Driven SE? Thus far all the headphones I've owned have had improved sound from the balanced out put of  my amps.

Doggone it Mike, if only I was aware of your impressions, then I could have saved myself the expense of the Emo and the Lyr!

But, and you may agree, this is as much for the journey as anything else.  I very much appreciate my current gear, and most importantly, I know why.  If I went straight to buying the MHA-100 or a Liquid Gold, it would be satisfying but with still kind of a hollow feeling.   
 
Schiit gear is somewhat of a bummer head scratcher to me. I've owned the Lyr, Modi, and Magni and sold them all.  I've heard the Mjolnir at numerous meets, and heard the Rag prototype twice, most recently this past May at THE Audio Show.  Just may not be my thing.  I love Jason's story and definitely support USA made products, so I'm kinda bummed at not being entirely jazzed by the products.  That said, I still need to hear all the v2 stuff.
 
Bringing this back to the new C-2, after owning the Compass and C2C a few years back, I wasn't drawn back to Kingwa's products until reading about the Master 9.  Then he came out with the C-2 Class A, and it all just resonated with me.

Hmmm this is the first bit of Negative feed back I've heard about Schiit gear... but we are on a AGD Thread, and I do have a NFB10ES2 sitting next to me xD

I currently use the NFB28 and I wonder how it compares to the 10es2? you think they are similar?. I know the 28 is a bit more powerful, but I actually bought it looking for a used 10es unit. I happen to reallly appreciate both the DAC and the amp of this unit. THey are exceptional with the ZMF x Vibros, and HE560's(grill modded and pad modded). I still think about getting a Lyr and attempting to use it as a preamp and start off by connecting it via rca in and doing a loop? Do you think if I connected the Lyr to the NFB28 I could use it as a preamp for the NFB28 having the DAC go to the Lyr and then the Lyr back into the amp section of the NFB28? I do not know if it could work.

I actually turned it arouind and really checked it out, and realized no go off the bat. It can be used as a preamp which is too bad because that would be a nice feature.,

It can be used at preanp but you cant loop back lyr preamp tp nfb28
Since yoylu can only use dac or preamp function at the same time,so when you use nfb28 as dac its receiving data from digital input,if you use it as preamp/analog amp day from dac->PREAMP->NFB28 then the input selection is now analog input,theres no way to activate two different input at the same time,thus no loop back

I'm happy with my SA-31....

Similarly, any update on the sound with jumpers?

  Hi anyone hear c-2 with Mrspeakers alpha primes? I have an NFB-15 but am considering a move to a "more sparkly" sound.
 
thx

Also, has anyone an idea of C-2's power in mW @ 50 Ohm?
 
I think I'm putting my 8 week old NFB-15 & 10 week old Mad Dog headphones up for sale in uk to help towards a new Amp. £350 plus shipping for the lot
