Is there someone who heard both C2/C2C/C-2.1 and Lehmann BCL/Lovely Cube/Matrix M-Stage/Burson HA-160?

argh! something else came up - the nfb-10....seems to be as good as the nfb-2 and c2.1 in  1 package! im going to ask kingwa what is better!

This is what i just asked on the nfb-10 thread - 

 

(replying to someone)

 

"oh i know, i was deciding between nfb-10 vs nfb-2 + c-2.1 for akg 701. But the thing is if i went for the nfb-10 i would have to go for balanced to get the best out of it right? and the cable replacement would cost £238. So what do you think is the best option - 

 

nfb-10 + price of akg k701 with recabling would be (582 + 165 + 238) = £985       (balanced operation)

 

nfb-2 + c-2.1 + akg 701 (635 + 165) = £800     (unbalanced operation)

 

What is better!!!!!!!!!!!!!!!! "

well : i think you read that too on the NFB-10 page from audio gd i quote :

 

"
 

 

 

Well in the Audio GD NFB-10 page you can read                                                                                                                                           

"If we only use the RCA or 1/4' headphone output, is the NFB-10WM wasted or not fully utilized?

 The NFB-10WM is a real balanced output DAC and headphone amp, it has balanced (ACSS, XLR and balanced headphone output), single-ended output (RCA and 1/4' headphone output). There are 4 ACSS modules in the NFB-10WM for balanced output, and all the ACSS modules have balanced input, so even through single-ended output, the WM8741 DA chips will perform fully."

 

It's sure that the best is balanced from NFB-10 i guess , but at first you can run from the RCA output , and later upgrade your K701 with balanced output , if i didn't allready have an NFB-2 i think that i would go for NFB-10 .

hm, so you think that the nfb-2 is just as good as the nfb-10 dac wise? But to get the best out of the amp section i have to use balanced?

In my opinion after reading the technical datas avaliable at audio-gd , the NFB-2 seams to have a slighty better PSU implentation 

 

For NFB2

 

" The NFB-2 uses 6 groups of high-quality class A parallel connection PSU with dedicated DC supply.
 The class A parallel connection PSU has very high input impedance for avoid pulse through the PSU from affecting the DAC and low output impedance with very fast speed and high linear , so it is a very clean power supply. In my experience, its sound is better than battery power supply, better human sound and neutral."

 

 

The NFB-10 

 

The NFB-10WM uses 7 groups of high-quality PSU with dedicated DC supply. Digital and analog voltages each have separately isolated internal power regulations.
The analog power supply is more important for sound reproduce, in NFB-10WM, the +15V and -15V for the ACSS analog output stages are high speed Discrete PSU. They can offer pure and quick power supply for driving the headphone exactly. The high voltage power supply can drive most headphone from 15 to 600 ohms as well.

 

C2.1

 

C-2.1 applied two groups of The class A parallel connection PSU for the ACSS analog output stages.
 The class A parallel connection PSU has very high input impedance for avoid pulse through the PSU from affecting the DAC and low output impedance with very fast speed and high linear , so it is a very clean power supply. In my experience, its sound is better than battery power supply, better human sound and neutral."

 

 

I am just quoting what i read from audio GD

 

NFB 10 had to power a head amp and  DAC , in my interpretation is that the Combo NFB-2+C2.1 in unbalanced output should be only slighty better than the NFB 10 , it's like the NFB2-3 , the difference is not huge ... 

 

But NFB 10 with balanced should be above unbalanced NFB2+C2.1 

 

I can be totaly wrong too , it's just my intepretation ... let's see what kingwa will reply :)

ok well i got a reply from sai, and this is what they said - 

"Because the NFB-2+C-2.1 is a Single-ended combo,so that if connect to the balance gear,that is can not disappear the performance of the balance gear.

And if you want connect the gear with other balance for combo,that the NFB-10 is well,but if you do not want the balance combo,that the NFB-2 +C-2.1 is better."
 
which i find hard to interpret into actual english.... but what i think they mean is - if you want to connect balanced to balanced get nfb-10 and if u want single ended get the nfb-2 + c2.1 but ultimately balanced is better.
I think this is what they meant....
if anyone can decipher that better i would love to hear it! lol
 
All i was asking them is "I was wondering how does the performance match up for the nfb-10 compared to the nfb-2 + c2.1. ".....which i dont think they answered very well , however i did say other things which might have confused them and made them forget to answer this properly. This is what i said after "Also If i use the unbalanced 1/4 connection for my headphones on the nfb-10 wouild it be worth it over the nfb-2 and c2.1 or would i have to use the balanced output for the biggest benefit. " 
i think i just confused them...made them forget the real point of what i was asking lool  sorry

next time ill tell them to reply in chinese and ill use google translate! good idea huh!?

well from what i understand , for not balanced operations NFB-2+C2.1 will be better , i don't think that the margin difference between NFB-2+C2.1 and NFB10 in RCA output is Huge , NFB-10 should be a Very Nice setup to Drive a K701 , better than a M-Stage ... 

 

Audiophonics a french supplier (with both matrix products and audio Gd guears) send me a mail where they clearly stated that C2-SA and C2.1 are electronicaly and sonicaly superior to the Matrix M-Stage in their tests .

 

unfortunately for me the last C2-SA seams to have been sold , no more in stock ...) , better for me , no more choice , i will have to go with C2.1 (but directly from audio gd :p)

 

Soo it's clear if you plan to go for balanced output in the futur go with NFB-10 , in rca mod it will be a great buy , just slighy under NFB2+C2.1 and latter upgrade your K701 for balanced operation .

 

Buf i you don't want balanced operation stay with NFB-2+ C2.1 . 

post #29 of 63

ive decided that i will in fact go for the nfb-10 ! :) with balanced operation because i heard by many people that it is better sonically.

 

also you said that you have to buy directly from audio gd, ive looked on your profile and it says you live in paris? im not sure if they do but ampcity might ship there :)

post #30 of 63

I prefer the sound of the C2 on non balanced headphones to the NFB-10 and yes I have compared them directly using Sennheiser HD800s and AKG702 headphones.
