Recently, I swap my Rotel RA-970-BX (60W, integrated) back with HE-6.  To my surprise, I like it quite a bit this time.  The upper bass is more impactful and solid, and the attak on the midrange and treble is harder.   I was pretty happy with it.  And if I want to be picky (like if I spend $1K on it), then I'll say the treblem can be smoother and juicier.  Therefore, I imagine A1 may be a good fit based on what I read.

 

Anyone has comments on this?
 



 


See if you can find more power. The Rotel monoblocks have more than enough power and squeezes the breath out of these orthos. 125w X 2. If you like the Rotel, it's worth looking for but hard to find.

I want to add this too about impedance. When I placed a 10 ohm resistor in parallel with the 6's 50 ohms to bring down the impedance to 8 ohms on my speaker tube amp, I noticed that the highs became smoother. Is it acting like a low pass filter? Or maybe because speaker amps just don't like driving high impedance, they're usually designed for 4 to 16 ohms. That could be the effect that some here have reported.

I have read several times in this thread that the SPL Phonitor is not enough to drive the HE-6. 

And, I suppose I believed that.  Or, I should say, it makes sense mathematically.

And thus, owning the Phonitor for nearly a month now, I hadn't even gotten it and the HE-6 in the same room together, much less one plugged into the other...

 

However, I kept remembering the Head-Fi TV episode where Jude said (twice, in fact) that the Phonitor drove the HE-6 well.

 

So, tonight, I plugged the HE-6 into the Phonitor for the first time.  And, the result?

 

Well, the HE-6 is now tethered to the Phonitor and is likely to stay that way for the near future.

 

I'm not trying to impart a lesson here.

I'm just saying that maybe I've been in the habit of reading this site a little too much...

And have gotten out of the the habit of letting my ears and brain defy my expectations.

Amazing how they can do that sometimes if I'll let them...  beyersmile.png

 

 

Cheers, and happy listening!

Interesting. Just a quick question, how high do you have the volume dial and how does the sound compare to your "go to" HE-6 amp?

 

Thanks!

well, peter...
i'm not a loud listener, to be honest.

i had the volume at 12 o'clock to 12:30 at most.

and it was really nice and full.  none of the thin sound of an under-driven he-6

 

with the other two amps i use, i have never been really happy with the sound.  i have to confess.

 

with the speaker amp i have been using - the virtue Two.2 - the sound is.... i dunno, hard to describe.

i would say "overly dynamic".  shouty.  and a bit analytical.

 

and, with the little dot, the other amp i use, it's an OTL.  plenty of power and beautiful sound with the T1 (for instance).  but, i have to crank it up to 2 or 3 o'clock to get it to sing with the HE-6.  and it is a bit "slow", not allowing the speed and foot-tapping prowess of the he-6 to shine through...

(i will confess that i haven't opened up the case and switched the jumpers for higher gain.  i may do that soon.)

 

but, the phonitor sounds really really good at 12 o'clock on the volume dial.

the sound is solid, meaty, yet wide open.

the sound is immersive.  and the soundstage is great.  mostly frontal  - i.e., deeper than it is wide.  but very impressive.

 

the phonitor is basically neutral.  so the he-6 is still 5% brighter than i'd optimally like, but i was so impressed with the sound that i could live with this setup and no EQ if i had to. 

 

i have blown a lot of money chasing great sound.

so i guess i couldn't help but share when something like this surprised me in a pleasant way.

Cool...thanks Brent. I don't listen overly loud either (typically 70-75dB with 80dB peaks.... ish). Interesting that the Phonitor packs quite a punch (along with looking very slick).

 

Cheers.

In layman's terms you might say that with the box you are less likely to damage your headphones or even your hearing if your management of the volume control gets a bit careless with high-powered speaker amps.

Just speculating here, but it might have something to do with a "more than adequate" power supply in that unit? That is something that wouldn't show up in the specs but would offer a higher current reserve.

You are less likely to damage your amp.

post #4195 of 14883

It doesn't make sense, right? how can a headphone damage a high powered amp?

post #4196 of 14883

It's just OTL tube amps that are likely to suffer damage, no worries with solid-state equipment.

Untrue. Transformer coupled amps have been damaged. When voltage is reflected  back because of impedance mismatch how do you know its affect on the circuit? Unless you're circuit is absorbing that energy and dissipates it.

Thanks, post corrected:

Fang is going to send me an EF6 as soon as possible, and all I know is that it wont be too long of a wait - but for me "soon" can mean 6-8 weeks just as easily as it could mean 2 weeks.  I'm not one to press the manufacturer incessantly about delivery dates, and I'll sit back and wait for as long as I can before I write asking for updates.  So, I likely wont bug Fang again before RMAF in 8 weeks.  

 

At the last RMAF I liked the EF5 more with HE-6 or HE-5 LE, because the prototype EF6 was still a little underpowered and not as warm sounding (more analytical).  I don't think the current EF6 has much in common with the very early model shown last year, and I'm excited to give it a listen.

Your Phonitor experience seems to be somewhat similar to what I heard with the DACmini (see bold) when set at about 1-3 o'clock on the volume with HE-6.  I still prefer the extra warmth and power of the EF5 with the HE-6, but the DACmini could be used regularly to listen to the HE-6 if I didn't want to play them at high volumes. If I had the optional gain of 10 instead of 8 then it might be even better, but I wanted to be able to really enjoy IEM at low volumes with the DACmini.

 

So, with HE-6 it's just a little less powerful than the EF5 and slightly brighter than I prefer, but still enjoyable with better freq balance than the HDP with the HE-6.  The DACmini > SR-71b > HE-6 is still a better choice for me and the main way I listen to them in my bedroom rig, although with the LCD-2 I think the DACmini headphone out works a little better for me than the balanced SR-71b.

 

Another note - my SAC KH1000 amp that's made for AKG K1000 has more power but is slightly too aggressive sounding with HE-6 to want to use it all the time (which made it perfect for the K1000 which felt bland with lesser amps).  This goes back to what I said before, that I'd prefer better sound quality and synergy more than having the most power.
