well, Koss UR/30 definitely no go. No difference between old sony ac receiver and this amp. I will need to look at some HD 600 and above.

It's not that it particularly bothers me.  A good sounding amp is a good sounding amp.  I don't plan on buying it because the word "warm" scares me away, which is unfortunate because only through listening to it myself could I know if it is too "warm" for my tastes.
 
The HF cutoff is more a nagging interest than anything else.  A curiosity. 
 

The bold line which I waiting for explanation from mr. kingwa.. we are the same way brother.

We must had the NDA with Tenor company, then we can applied the TE7022.
I don't want againest the law, We can't reveal about the TE7022 built in technology.
You are better send email ask Tenor company direct.

Well, I have to clear a point. I like NFB-12.
It's a well built DAC & AMP.
It's sound very good with my headphones from my sensitive Livewires Trip to my full size HE500.
It's just the USB receiver behaves abnormal in the measurement, and I wish to know where it go wrong.
 
If I don't like it, I'd have already take other DAC/AMP, wouldn't I?

Now that Kingwa has revealed the TE7022's internal circuitry affects the FR and his non disclosure agreement, (NDA?) with Tenor limits his ability to reveal the specifics, I for one feel like we have an answer as to killKli's question. Going forward. I really look forward to members opinions and impressions regarding the newest version with the switches to change the filters easily. I think this upgrade came as a result of our feedback in this forum. I am sure there will once again be complaints regarding frequent upgrades as a "problem". However, I for one think when people suggest improvements, and the company responds, this is a good thing, not a problem. BTW, hopefully someone here can devise some circuitry/switches, perhaps mounted in the top panel, to enable this upgrade in the 2nd gen models that use the jumpers. Kingwa maybe?

I also like the frequent updates.  I might shoot an email to one of the audio-gd guys before buying to see if an update to any particular model would be out soon.

Mind giving some impression about the hd650 + nfb12? 

 
I may be able to borrow a pair of hd600 and 650 in the next month. Kinda wondering if their "syrupy" sound sig will play nice with the nfb12

It has a fair bit of power, so most headphones will be driven properly on it.
Depending on your budget there are quite a few options available. I personally have tried it with the HD 650, and I can tell that it's a good combination.
I think it would be wiser to ask the same question in the Headphone recommendations thread, they will be sure to point you in the right direction. Do mention a budget, though!

Can't comment on the HD650 - will leave that to Tilpo - but IMO the HD600 does pair extremely well with the NFB-12.  I have the jumpered version, and am using the 4 x oversampling minimum phase softknee filter (good mix of clarity and warmth) - coax up to 24/96.  Detailing is nice, and with the slightly forward (but beautifully balanced) mid-range of the HD600, I find the NFB-12 to be a very good pairing.  It is a lot better than my E7/E9 set-up was.  More body.

I know Tilpo thinks it's a good pairing, but I think the NFB12 really doesn't do justice to the HD650.  I like the NFB12 as a DAC and it's OK with my DT880/600's, but not really with HD650's.  I would use veiled as an adjective for HD650 with the NFB12, but not at all with Bottlehead Crack or Hifiman EF5.

Do you think it's because it's quite a warm dac/amp with a warm headphone?

Yeah, must be it.  I know NFB12 has plenty of power, but 650's are like slow/dull on it.
 
And it's not the DAC as I can go RCA out to other amps and it sounds great.
 

 

[Brooko]

Thanks.  Suspected that might be the case.  It actually sounds pretty good to me with the HD600's.  Sounded great on the DT880s (250 ohm) when I had them as well.  I also tried going RCA out to my PortaTube just to see how it would sound - and that was a really nice combo also.

Have you tried your HD600's or DT880's with an OTL tube amp?  I think that'll take both those cans to a different level altogether. My DT880/600's are fine on NFB-12 but much better on the Crack.
 
 

 

[genclaymore]

I wonder how it would do as a dac plugged directly into the Matrix M Stage v2.

The Crack has always interested me - and probably will be something for the future. For now I'm going to replace my current IEMs so that will end up being the next big purchase for the first half of 2012 (SE535 ltd ed).  Was the Crack hard to build?  Would someone who has never soldered before handle it?
