Your amp for he-6 is Pioneer vsx 406?

I am not sure that asking about the loads for their amps is entirely new territory for them, but maybe I am missing something. And emails are pretty cheap. I mostly responded because the advice I got was pretty much the opposite of why you suggested. Whatever

 

I had a long email exchange with the President of Parasound on the subject of driving headphones with their speaker amps.  He wasn't surprised of put off by the idea, at all.  Very helpful and knowledgeable fellow.  When I contacted Parasound, I did so to a general email address.  I expected to get a reply from a service tech if anything.  But no, I got a reply within less than 12 hours from Mr. Schram himself!  and, on a Sunday, no less!

That's pretty cool, it sounds like they are willing to help. So what questions did you guys have for them if I may ask.

I have asked some questions too in the past, but the situation here is using a product that is not there's. And I did not think they would be helpful in this method. I guess I'm wrong.

Yes, the voltage associated with 150 watts across an 8 ohm load would be a bit less than 35 V.  

 

Assuming the amplifier in the example is voltage limited at that 150 W, then the max output to a 50 ohm load would be 24 W.

 

So, with a 150 W speaker amp connected to headphones, one must be careful of the volume knob!

 

Just because the amplifier is rated at 150 W into 8 ohms doesn't mean it always puts out that 35 V.  It only does when the volume is turned up very high.

 

Make sense?

For now yes, I will be using the Firstwatt F5 soon.

Hmm..Im actually getting much much better response from using just the DA8 alone.

Really?  Good to know!  I figured the DA8 headphone amp would be a bit under powered for the HE-6...

Yeah, its still underpowered, but the internal amp does have 1w at 32R, and is quite transparent thanks to the excellent power section. It's great if you're in a pinch, or want to drive some efficient cans off it. When I had the TH-900 I preferred the DA8 amp over other amps :blink:

The integrated amp of the DA8 has a good reputation, it's an admirable amp. But not quite enough powa for the cookie monster HE-6.

Might be a good fit for the HE-500's.

Bingo.

God, vocals on the HE-6 are just flat out sick.

I am SOLD.

 

So good that Id even say its as close as Ive gotten with the perception of being able to touch the singer of the piece over all the HPs Ive owned.

 

On that note, the DA8's sonic character compliment the HE-6 beautifully. I almost feel sorry for those whos doubted the DA8. If you dont feel like spending money do not read Project86's DA8 in-depth review.

Is the DA8 warmish?
