Hifiman HE-4 Impressions Thread - Page 124

post #1846 of 3219

Same here. My mini-X pot had a bad imbalance and I came to find out that the pot is only guaranteed to be balanced above 9:00 or so, which is pretty darn loud even on the HE-4. That on top of the noise floor made resistors a must. Still, after adding them I found no difference in sound signature, just cleaner without the noise.

I wonder how they'll market the 560 and 400i in power requirements/recommendations since part of their claim are more efficiency...

 

 

I can sense I'm being spoken about, which is fine I don't understand everything. THe trend that I've noticed is the more powerful the Amp the better the HE 4 and HE 400 seemed to sound, and YES I VOLUME MATCHED THEN with an SPL meter
 
most noteable, my Vali compared to my NFB10ES2 was decently fair grudge match with my W1000x SE vs SE, back when I had the HE 400, my poor little pb1 never did the justice the NFB10ES2 did, even then for $80 the Pb1 sounded a LOT better [even SE out] then the JDS Labs C5 that I owned for a breif moment.
 
Though this may be more of a quality over quanity issue. it could be that the more powerful amps [with the exception of the mini-x maybe] have a cleaner presentation than the lower powered implications. One of the things I like about balanced amps, in my limited understanding of how they work, is that by splitting the amplification into 4 channels reduces the distortion and works to maintain a clean sound, the result is both my Pb2 and NFB 10ES2 sound very nice! The SE outs of each are a little lack luster, and again my Pb1 sounded better than my JDS labs C5 and my Maxtrix M Stage [both SE and balanced out] although truthfully, the vali did sound better than the M Stage to my ears,
 
Still, it would seem when building an amp capable of delivering more power the designer may put more resources into preserving the distortion. 
 
But if some one want's to explain why the Vali despite having enough power, still sounds lack luster with the HE 4 I am ofc all ears.

I think this is true. Amps don't all sound the same, and some are better than others independent of power. It's also true that many higher-end amps have a lot of power, so there may be some correlation (but not necessarily causation) between power and sound quality.

It does seem that way as well

 

still if any one wants it I'm selling my Canare Balanced cable, my HE 4 is getting mini XLR mods

 

I just WISH hifiman would go the Azude Route and sell a Closed Back q.q

Quality is always going to be more important than quantity (so long as you have enough). Manbear does prove a good point though, maybe there is a bit of a correlation there, but my experience with speaker amps (only one) is that this is not the case. However, many people are in love with the mini-X.

 

As far as your dislike for the Vali+HE-4 pairing, that just comes down to personal preference. It's not going to sound as technical as a SS amp because it's signature is not that technical but more musical.

 

Oh, and I would also love to see a HFM planar closed back!

post #1851 of 3219

I wasn't talking about you in particular, just the discussion. Don't the Audeze closed backs sound meh compared to the 3s and 2s?

Out of all the amps I've tried and had, Vali, Yulong D100, Tubmagic A1 (both HP and speaker out), and the NFB-10SE, none come close to the Audio-GD. It might be unfair since out of the Audio-GD I'm going balanced but still the difference is very noticeable. The sound on the Audio-GD engulfs you with it's wide soundstage and rich bass/mids. The treble gets calmed by a hair, not enough miss anything but just enough so that it's not so intrusive. There maybe an argument on the balanced thing but that's another can of warms isn't it?

post #1852 of 3219

I would really like to try an AudioGD amp at some point, I've only heard great things.

 

I have yet to try balanced as I don't have any amps for that. Even the mini-X wasn't technically balanced since the ground is shared, right? Some day I'll grab a Mjolnir or something and have no choice but, circuit wise, I don't quite understand the advantage in terms of sonics. I'll admit that's quite a bit above my head though...

Yeah, that's correct. Just like a single-ended TRS plug only has one ground. I actually built my own mini-x adapter, and I only have one ground wire going to one of the black terminals. The other one just sits there with nothing attached to it.

I actually bought that Switchcraft adapter from your suggestion, haha. I eventually added a jack to the front for fun/convenience but ended up selling it all anyway.

True, the iBasso pb2 sounds VERY good, for about half as much as the NFB10ES3, it does a nice job of spiltting a SE source into a balanced signal. 

 

But, I actually remember'd today that I wanted an Audio GD amp, since I first joined here. I suggest you do get one! Better than every one says they are! And cheap as dirt! [although built like... something better than dirt xD] 

 

and yea balanced is another can of worms, there' have been a fair amount of debate, wheather the increased cost of a balanced amp is worth the supposed increase quality, some argue a SE amp with better compenants should match or beat a SE

 

but at the end of the day for me, the balanced amps seem to beat the SE amps in there price ranges, but that's just me! Plus it could be a simple case of " Audio GD is just that good" although some way the Schiit Amps are better, but they do cost a margin more.

Nice, which model? I was tempted to go with the NFB-28, but now that the Oppo HA-1 will be out near the end of the month, that's where my tax return will be going.

like wise which one?

The nfb10es3 should b good as well. not at the lvl of the 28 but still very good!

He'll be getting my NFB-10SE. I think the twin Wolfson are a prefect compliment to the bright HE4 and plenty of power with 9w to 38ohm.

I don't think the NFB-10es3 is available any longer. And yes, the SE is super tempting for the HE-4. But really, you cannot go wrong with any AGD product. Be sure to let us know what your thought on the pairing!
