Skylab,

What is your impression of HE-5 through Phoenix?
post #722 of 1668
I think the HE-5 though the Phoenix is fantastic. GREAT pairing, IMO. So good I ordered a set of balanced cables for the HE-5 so I can use them with the Phoenix in all its glory (cables aren't here yet, though).

Sell that junk and get an EF-5
Yeah, right...

...but look at this:

Head-Direct states EF-5's output signal strength to go up to 15 V at 32 Ohms... This means that when driving HE-5, EF-5 can give ~ 7 W (~ 0,47 A)!!!

In the same time, on low impedance phones, Phoenix is limited to (just) 0,2 A which gives voltage swing of ~ 6,4-6,5 V at HE-5's impedance of 32 Ohms and equals to power of ~ 1,28-1,3 W.

Hope I did not mess up those numbers, and sincerely hope that HE-5 does not need all of those 7 W... (or we'll be all hooking them up to the speaker terminals )

Thanks Skylab...

Now I can relax. There is a chance that HE-5 will match good with Roc...

2. While we're both using a Phoenix, perhaps the rest of the system I've been using with them (Music Gall 25.2 DAC and Denon CD player as a transport) are more forgiving than Tim's source

3. Tim is more annoyed by brightness even more than I am (hard to imagine)
This is very interesting, luckily you're in the same geographical area. So often on these forums we read disparate opinions about the same equipment. There can be numerous interpretations of these differences including the equipment not being uniform in sound from one piece to another, the listener hearing things differently or listening for different qualities, and the associated equipment to name a few variables. Here we'll have more control as you guys can listen to the same music with the same equipment and compare two versions of the same phones. I am especially interested as I have a Phoenix and plan to buy a pair of these phones soon. So am eagerly awaiting your findings. I certainly hope, btw, that the outcome is not that the two HE-5's sound very different from each other. This would implly that there are some quality control issues and that generalizations about the phones may become irrelevant. please let us know how it turns out

OP27 spec sheet. This is the output chip in the EF5 - do the real math.

It is a nice chip for what it does - it would make a great cmoy option too for those looking for a real budget solution.

I don't know if it is because of burn in or because I have just relaxed from new toy syndrome and started listening to the music, but these things are really impressing me right now. Damn good headphones.

Early / Immediate amp impressions

I received the HE5 / EF5 combo late afternoon yesterday. All the talk about tempermental amplification made me want to sample some ideas.

HeadphoneAddict inspired me to try the Qinpu A-6000MKII integrated tube amp to power the HE5 using the speaker outs (his favorable review of the A3).

Based on Tim (sibilance issues) and Yikes (tested only SE @ NY meet), I wasn't really confident in the Phoenix.

I was up 'til 3AM, first building a balanced Mundorf cable and then swapping amps. I got about 7 hrs burn-in on the EF5, 36 hrs on the Qinpu, >500 hrs on the Phoenix. I definitely suffered the sleep deprivation hangover at work today, but it was worth it.

These are PRELIMINARY findings (I will post again next weekend after the reco'd 200 hours of burn-in on are reached on the EF5):

First off, I really like the Mundorf. I simply preferred it over the stock cable. I A/B'd it back & forth several times (using an SE adapter on the Mundorf) and have no desire to use the stock any more. That being said, the supplied cable is very good.

I did not like the A-6000MKII as a headphone amp using the speaker posts. I didn't bother trying to use the preamp outs to power the HE5. Compared to the others, I felt the highs and mids were recessed.

I thought the EF5 did a nice job. It's got plenty of power to spare. I never went past 12:00 on the dial. I didn't like the high gain setting as it wasn't clean sounding. It kind of strikes me as a "Phoenix Mini-me" in appearance.

The Phoenix rocks! Yeah I had to turn the vol up a little more, but WOW! , it was so clean and natural sounding that I stopped testing because I got side-tracked listening to the music. I didn't bother testing it SE knowing that it is simply a compromise based on the amp's design. At this premature stage, The Phoenix in my set-up did everything better than the EF5.

Phoenix advantages: ACSS inputs, balanced output, better DC cables, proper burn-in.

you made the Y on the cable really long. i am another one without the sibilance issues with phoenix . i still cry a little inside thinking the early adopters of this headphone didn't get extra plugs

Fang should send the extra plugs also to the early adopters he has the adresses somewhere,at least we made the first great impressions of HE-5 ON Head-Fi.

and it costed us $1 more. Nankai said they would add it to their site but i don't want to pay for plugs someone else got for free =/

HE-5 initial impressions

These brief impressions were done with NO burn-in.

My reference is the D7000. I picked the D7000 over the HD800 in my set-up with the stock SE cords and no burn-in. I knew that the 800's were technically the better phone, but preferred the Denon's sound / fun factor. I actually prefer a smaller soundstage

I mod'd the 7000's with a silver/gold alloy balanced cable and added the JMoney pads. This tamed the bass, and improved just about every aspect of the phone. This was my most balanced, natural sounding experience, until now:

Straight out of the box, the HE-5's are just amazing. After listening to these babies, I know realize that my mod'd 7000's have a significant scoop in the mids, have a hot treble, and still suffer from bloated bass. When I demo'd the 800's on my Phoenix, I asked (among other questions): Where's the bass? That being said, the HE5 has proper bass levels with superb definition and weight. On the Phoenix, the bass is present in full force. You'd only miss it if you are accustomed to an artificial presentation.

The treble has great sparkle, detail, and good energy. Defintely significantly better detail, less energy then my Denon's. I could listen at louder levels without fatigue.

Now hear this: NO SIBILANCE! I don't know if other's received variants or if the source is a factor. I listened to lots of baroque vocal works with no problem. I use a CD transport, and listen to hi quality recordings that don't use compression as far as I'm aware of. Hopefully other people who are having issues, get a quick resolution!

I did notice some crackling that was caused by not having the cable screwed into the connector with proper tightness. The connectors do have a short learning curve. QC however, is outstanding.

I don't know if it's the photo or if you like short Y's, but it is only 12 inches long, with the entire cable measuring 5 feet.
