IMHO I could not get rid of the K812 fast enough.

Why?

 

[Fearless1]

Why?

Not for me.

After considering to buy a Vali amp, i was told that it may not have enough current for my Hifiman HE-500. So i just had an idea.
Would it be possible to use the Concero into my Matrix M-Stage amp and then as a preamp into the vali.
Please tell me if that is advisable or would the sound be too colored/altered because going through two amps?
 
Since i have no idea if this works i would hope for clarification.
 
thanks

According to innerfidelity the Hifiman HE-500 needs 2mW for 90dB, schiit say Vali does 550mW into 50Ohms, so plenty of power.

Won't increase the max current from Vali if that's what you want.

Right. And you would risk over driving the Vali.

By that measurement you would need around 1W to reach 117 dB SPL for 27 dB of headroom to avoid distorting on peaks. I'd say that the Vali is just a tad short on power for running the HE-500's above modest volume. If you're exclusively listening to highly compressed (loudness) music then it's probably OK.

If Schiit are quoting their power output as RMS continuous at some arbitrary low distortion then the dynamic power should be ample to get above (arbitrary) 117 dB.
Jeez, for 117 dB my stereo would need to output kWs

Nope, by the figures given in the post 117 dB. Actually if you look at the specs of the headphones, 1W should take you close to 119 dB. No kWs are required. I own both products.

 

[jimmers]

  119 dB. No kWs are required.

re: "Jeez, for 117 dB my stereo would need to output kWs

By "my stereo" I meant my speaker setup (84 dB/Watt @ 1 M, 3 metres listening distance) sorry for the confusion

My HD650s don't need kWs (just mWs)

 

[amigastar]

Alright guys,
 
thanks for clarification.

So you're thinking of upgrading the amp? 

 Just kidding

How is Vali compared to Fiio E17 amp ??? Though i use them with HE-400.....Any comments

 

[Vma5]

I've been using the Modi/Vali combo for last week or so and I like how my HD700 sounds with the Vali. Although I have one problem with it, the noise floor seem to be bit too high for them. Hissing is suprisingly loud, it blends into the music when I'm listening to noisier songs (rock, electronic, etc.), but in classical, ambient and acoustic style of music the hissing can be bit distracting. I'd be interested to hear if other HD700 owners has had the same experience.

so I was looking for a DAC I can connect to my Vali Amp I was going to get the Modi DAC but seems it is not compatible with DOLBY/DTS/PCM like the Fii0 D07 cheaper and better then Modi amp even the schiit tech said I should buy the FiiO D07 over the Modi DAC
 
Here is the conversation

I'm sure this belongs in the Modi forum, but I can pretty clearly see the line of reasoning from Schiit. 
 
I believe most sources of Dolby and DTS are 5.1 streams, so 6 channels. 2 Channel DACs are only meant for 2 channel material. I'm not sure what method Fiio uses, but somehow they are taking 6 channels and converting it to 2. You're not getting a true Dolby or DTS signal out of those RCA jacks.
 
In addition, Schiit really isn't "into" all those different codecs, file types, etc. There's a lot of gimmicky marketing stuff around Dolby audio, DTS, or other "submersive surround sound" software. In my experience all of them drastically reduce the sound quality you're getting.
