Amps that can drive the HiFiMan HE-6 planar headphones - Page 236

Never heard the Allnic with a HE6, but folks that have tell it does a fine job with 5wpc.

 

The WA5 with 8wpc does a great job with the HE6. Folks that have compared the WA5 with a thumping huge wattage solid state amp tell me that it gets 99% of the performance - just drops a sliver of the bass response.

You mean even the WA5 with 8WPC it gets just 99 of performance and dtops slightly of the bass response?

The slight drop in bass response is the missing 1%.

 

Rather than me try and paraphrase the opinions of others, best thing is to read them for yourself - link to a post a little earlier in this thread:

 

Link.

 

EDIT - I come away from that email exchange with someone with experience of driving the HE6 from the WA5, and also from thumping speaker amps, is that you gain a small bass improvement from the extra megawatts. Other than that, the 8W of the WA5 does the job nicely, and you get the tube magic of the WA5 (great musicality). I'll take that trade anyday.

 

I have thought about hooking up the HE6 to the speaker taps on my 20W TRV845SE amp, but the WA5 does such a great job driving the HE6 that I struggle to find the motivation to do it.

Please try it anyways and let us all know the results :D

So ... Dat mean that my little dot VI+ that deliver around 5wpc can't handle well then ? 

 

Cuz they have a lot VRMS too.

 

  • THD+N:
    • 0.02% (2Vrms @ 1000Hz)
    • 0.06% (10Vrms @ 1000Hz)
    • 0.3% (20Vrms @ 1000Hz)

Perhaps. Best I can tell - and I am a rank amateur at this - it is more than just the raw wattage. The amp has to be able to swing current/voltage to feed the HE6 as well. The Allnic appears to do this. I know the WA5 does it. I have no clue how good the Little Dot might be at this.

 

The only way to be sure is to try it.

 

In my ignorance, I tend to look at the size of the transformers as a rough guide. On the WA5 and Allnic these are huge beasts - taking the weight of the amps into the "my spine just shattered" territory. Not so sure about the Little Dot.

 

I just don't know if the size of the transformers is even relevant to this - just a guess.

 

My TRV845 amp drives 88dB floorstanders with ease - only 20W, but it weighs close to 45kg (100lb). Lifting that bastard solo is NOT fun.

2.0Vrms would be how much output into an 300 ohms headphone. Is it 20 mW into 300 ohms?

 

nothing to do with HE-6, just for my understanding.

Actually, practically no one came into that small room that a couple of us were in. We had easily the best setups in the whole meet. Most of us brought more gear than vendors too! Yet not many got the chance to listen to the best HE-6 and HD800 rigs.

 

I'm still waiting on Jude to write something about his impressions on my rig. :rolleyes:

+1

Other commits prevented me from meeting you and your fab setup. Still wanna hear it - a mini-mini meet, perhaps. Sadly, my own setups have been and will be mothballed for a handful of months.

did I just......no way :blink: ..... I looked up the littledot MKIV instead if MKVI :angry_face: which gave me :
 

  • Power Output:
  • 500 mW @ 300/600 ohm
  • 300 mW @ 120 ohm
  • 100 mW @ 32 ohm

that's where I got my "50 times more power" figure :rolleyes:
the MKVI should do well with the he-6, but in my opinion you'd be better off with a speaker amp(especially at the MKVI's price) since they "typically" offer better value overall (and a beefier power supply).

Vrms is already the DC equivalent approximation of  AC voltage.  If you mean peak to peak voltage an approximation would be 2* sqrt(2)= +-2.82 V.

 

With 2 V DC or rms, into a purely resistive load, power would be P=V^2/R or here 4/300 or 13 mW.  But in practice this type of calculation is only useful as a very rough approximation.
