HiFiman HE-500 (HE as in High End) Proving to be an enjoyable experience in listening. . - Page 567

Haven't tried the Mini-X. but hiss and hum is very dependant on the source, and on what else is currently plugged in using the same circuit to your wall.

 

The Lepai will hiss if the wires aren't correctly seated, or if I use a ****ty source like my PC headphone out. Once fixed, the hiss goes away.

 

Hum can be fixed by trying different outlets on different circuits. If the hiss goes away on another circuit, you'll need something like this:

I have had an Emotiva XPA-5 in my home theater. While it was a great piece of equipment, I recently replaced it with a Behringer NU4-6000 that was half the price, puts out more power, and sounds the same. You cannot tell the difference in an A/B test. I would like to hear the Mini-X, but I doubt it will be 10x the cost worth of a difference, considering I prefer the 2020a+ over my newer 200W Lepai as of now, because of the adjustable tone knobs.

 

When you deal with solid state amps, as long as THD is low and similar between models at the same power, you will be hard pressed to tell the difference between two of them, no matter what price bracket they are in. Power is power, unlike with tube or hybrid amps.

One of the most epic posts I've seen to date.  :p  That statement is so loaded I don't know  whether I should open up the can of worm...

Yes, please do so, and then A/B test to come to an actual instead of theoretical conclusion.

 

In a blind, gain structure matched A/B test, not one person in my theater room could tell the difference between my system powered by the $999 XPA-5, or the $450 NU4-6000. Those are the actual results that matter, and "audiophiles" will cry all day long about the transformer size difference, capacitors, topology etc etc. The end result being that if it sounds the same, it does not matter.

 

It is also the reason I no longer use Krell amps. When it comes to actual performance, the sound is so close, at the same power, that money is better spent on equipment that will actually change the sound signature significantly, aka the speakers, room treatment, preamp/DAC, and in this case, the headphones themselves. A different headphone will be the biggest change you could ever introduce into your audio chain, not the amp powering it, and it is the reason why most of us bought the HE-500 in the first place.

 

It is also the reason my home speakers are DIY and were designed by myself and several other well known speaker designers and was simulated prior by the woofer creator himself. These $1,000/pair handbuilt towers absolutely destroyed a pair of $10,000 Legacy Focus SE towers. The measured frequency response was much flatter, and the constant directivity waveguide+CD used provided a much bigger soundstage and sweet spot. Actual detailed measurements can be found at avsforum on it.

 

I also prefer not to chase the rabbit with hundreds of tubes just to introduce the distortion that sounds pleasing to me, which will also give people fits, and I don't care. I've done it before and no longer wish to do so. They serve that purpose in my guitar amps when I want... good distortion. I don't need to spend $1,000+ and hundreds on tubes just to find the sound I want that a $20 Lepai provides for me on this headphone, and that's my choice.

 

I fell for the exquisite cable bs too at first, which is another sham that most people refuse to acknowledge. Don't even get me started on balanced setups at 2x the cost or more vs. unbalanced with less than 2ft cable runs and low power fed to them. Works great when feeding 2500W+ to my subs via Speakon to avoid noise and hum, but again, not worth the extra cost for slight gains when $20 suits me just fine, with a black background, on my HE-500. 

 

I've also stated multiple times that I prefer my Lepai & HifimeDIY Sabre U2 over my upgraded TCOX Audio-GD NFB 11.32 with ESS9018. That's a significant cost difference, and from what I found, the power being fed into this headphone is more important than even the DAC implementation. This ESS9018 implementation should run circles around the cheap chinese Topping amps and a low cost SABRE DAC right? Nope.

 

Now please, tell me again why spending more money automatically equates to better sound?

lol.  I wasn't disagreeing with you.  I just stated that your post was one of the boldest, straight up posts I've seen.  It all comes down to if you are happy with your setup and getting the sound you are satisfied with, it doesn't matter how much you pay.  What a subjective can of worms.  ;)

True. No reason to knock it though.

 

I'm all about bang for the buck.

Don't tempt me with that lepai. It's like 30€ in eu...

Any of the Topping amps would work. Spurxii has the TP60 I think, which is still pretty cheap for what you get. Buying a cable to use on the amp would cost more than the amp does.

 

They're so cheap, it's worth a try. They can be used to make a small bookshelf stereo system if you didn't like them with the headphone.

Same. After reading about these $20 amps for a few weeks, finally decided to check it out on Amazon. All under $30. Looks a bit like the O2 in form. Got tone controls as well, so appealing from that aspect as well. Anyone have experience with this and the Audeze pairings? Will probably use it with LCD-3 for bedside rig or something like that.

 

One quick question: does it accept banana plugs?

Haven't followed these amps previously. Are the topping amps better than the lepai?

I use the Topping TP60 on my B&W 602s as well as the HE500s and they match really well. It's a very very detailed but dry sound. I like it so much I've got 2

Topping and Lepai both use the same Tripath Class T type amp. Topping has models that have more power and are more refined, but the Lepai at $20-25 is an awesome value.

 

The bass knob adds that extra bit of bass into the HE-500 when I want it, making it perfect. It does a better job than any software EQ at that.

Some of the Topping models, and the $129 Lepai take banana plugs, but the 2020a+ is bare wire.

Thanks for the info bhazard.

I also just got the Schiit Magni in. Has plenty of power to drive the HE-500 and just about anything else, but lacks the impact of a speaker amp, and lacks the warmth of the Lepai and what some tubes would add. Still awesome for $99 though.

Do you have a link to a premade cable that will work with the Lepai?
