What is actually the impedance? I found on the Internet different values (64 or 38 Ohm). Does it need the amplifier for a good volume?

According to their website 38 Ohms. http://www.audio-technica.com/cms/headphones/ef4d606736c89301/

For the most part no because most motherboards nowadays van drive up 80ohm headsets. Anything 100 and above may require a amp/DAC or a nice sound card that can drive them. Check your motherboard first if anything else. I run a gigabyte ud3h 2013, idk specifics, but it runs them fine. I later bought a sound card though so I can drive the bass up.

The MB42X's impedance varies between 4 to 8 Ohms. Care must be taken to ensure that the amplifier being used is capable of handling a 4-Ohm load. Improper amplifier selection or setup may result in permanent damage to the amplifier or speaker. These speakers can handle amplifiers with outputs betwee 15 and 100 watts per channel as long as reasonable care is exercised. Personal Note -- These speakers are built to impress you with their sound!!!

This unit is built for output impedance 4-8 Ohm. By using 2 Ohm speakers you are risking to burn unit amplifier; this is not really high end equipment. This unit has RCA output and option to attach an amplifier; that would be better way to go.

It's an active amp which is why it plugs into a wall outlet. It amplifies the signal from the input and splits it into each output, and it has plenty of cojones to drive my over-ear phones into heavy distortion. I assume that's what you mean by "drive." Not sure what you mean by "how many Ohms can it handle". Headphones are generally low watt, high impedance--like 40+ ohm. I personally wouldn't try to drive a low impedance load like a speaker with it.

I would recommend wiring for 2ohm setup. @ 1ohm it might be pushing the speakers to the limit. Power acoustic amps are inexpensive because they have a lot of distortion so don't Max them out. I'm running 3 @ 2.6 ohms on a hifonics 1500w and they bang!

The 6 Ohm setting on the amp should work okay for your nice 8 Ohm speakers. Higher impedance speakers should dissipate less power and consequently might sound a tiny bit quieter than lower impedance speakers at the same volume setting. But I doubt you will notice any difference.

It usually means 8 ohms is the recommended speaker impedance. Using lower impedance speakers like 4 ohm draws more power from the amp and can cause the amp to overheat. But generally in quality amps this will only be a real concern if u constantly blast music close to maximum levels. Some higher end brands will say they are 8 ohm but 4 ohm stable meaning they can handle the lower impedance

True Four Ohm Impedance technology: speaker's 2-ohm impedance combines with speaker wire impedance for a 4-ohm load.Awesome speakers in my opinion. I had an 840 watt 4 channel cheap brand amp pushing them and they sound amazing. The tweeter attenuation is a nice feature too.

What matters is the impedance. Most Amps are 8 ohm as are speakers. When you hook multiple speakers in parallel the impedance goes down. The selector ensures that the impedance is at least 4 ohms even when as many as eight speakers are hooked in parallel (and would otherwise present 1 ohm of impedance). On my Yamaha receiver there is a switch that allows for a 4 ohm load and that is the key. You can probably run a 4 ohm load from an 8 ohm driver, it just means that more energy is dissipated in the amp than in the speakers but hopefully not so much as to do damage

I would say no. The comments I've read (on head-fi) say that to get decent output out of high-impedance cans you'll have to use something more powerful. If going the vacuum route, that might be the Schiit Lyr or Asgard 2. I am using my Valhalla with 32 ohm headphones so can't comment on how it sounds with 600 ohm headphones connected.

You did not mention what you need it for and what speakers you have. For amplifying voice it is more than enough power. If you're a dj and are planning to play music you will need a second nu 3000 connected to a subwoofer. If you have 8 ohm speakers you get sbout 200 watts per channel. For more power you can connect two speakers on each channel making an impedance of 4 ohms.

From the manual: "This amplifier is not recommended for impedance loads below 2-Ohm stereo/4-Ohm bridged for the front/rear channels and 2-ohmfor the sub channel." I think you may have overheating issues with a 1 Ohm load.

I use the 250 ohm and it works fine with my macbook and pc even without an amp. I do have a fiio e10 but the loudness is acceptable even without an amp. Hope this helps.

50 ohms - I actually measured it with an impedance analyzer... very close to 50 ohms non reactive.

I left mine at 8 ohms because it had plenty of power at 8 ohms for me, but you can easily change the receiver impedance to 6 ohms if you want to. Download the Yamaha manual for the receiver from their site and it will show you how...it's fairly simple.

According to the manual (which you'll need to print out from a PDF) it will support 4 ohm speakers. You set the speaker impedance as part of the set-up procedures. I don't know the power level, but I imagine there would be sufficient. Hope this helps.
