I have a DAC that outputs 2 volts RMS per channel into 10 K ohms. Is that enough power to produce good volume in these 'phones?

Thanks for your question. Considering these have an associated amplifier, that should be fine. This is a fantastic sounding phone. World Wide Stereo is 35 years old and a very proud Koss dealer.

Yes, 2v output is the industry standard. The Koss amp will be fine with that input.
467744
Yes it's enough. Because the DAC does not support the power but the E90(energizer does). Do go ahead.

I don't know about the voltage output on a dac, but my Cambridge Audio DacMagic works fine with my ESP-950.

its not just an amp, its a better dac. you headphones can run fine on the iphones amp. I like having the better dac

These are very efficient, so they would produce some decent volumes at 10 watts. Not enough for a large room or high volumes, but probably enough for listening at reasonable volumes.

It should do fine, although you'd get a better experience with a dac/amp combo like the fiios alpen e17.

the box states 63 ohms. when plugged into my ipad air, i need to max out volume to get decent loudness. On my Aune T1 amp/dac I have the gain set to 10gb and volume sits between 7-10 o'clock, which is moderate-loud volume for me.

The amplifier circuit has a maximum voltage gain of 10 (20dB). However, the actual gain you can get will depend on the impedance of the headset you plug into any given channel. The design calls for a 47 Ohm output resistor for each channel, but the two I received were manufactured with 470 Ohm resistors installed, so the output impedance was ten times what it was supposed to be. People getting units assembled with this error will see far lower gain than they should. Beware!

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 think DAC of this Item is not so good, your idea is good. There is a digital output.

I consider 75 RMS 2 ohms is fine. I think this speakers are overrated. I use them long time ago with my alpine V-POWER series amp, calculating 100 RMS 2 ohms per channel and soon burned the tweeters.Before that, I used 60-70 RMS per channel and everything was perfect.sorry for my bad english LOL

No..!! I've tested this headphone with my phone and it was just OK. I did not have to turn up the volume more than 1/2. If you use your smart phone as the music player, Shure SRH1540 does not require much powerful amplifiers, but when you use a small amplifier its sound and dynamics increase to a perceivable level. there's no need to use a DAC(every smartphone has imbeded DAC).

Yes you are right gain not pre amp set to about about 2/3 and RVC. Plus your MP3 player or phone to max

Unless you are getting noticeable electrical interference from a large graphics card I don't think the M50x will benefit from an amp/dac. I'd save your money for your next upgrade (because its an addiction).

I don't understand what you are asking. The power is ok but you have low volume?

Higher ohms are always compatible. As long as you stay above 2 per channel or 4 bridged you'll be fine with this amp.

This is right from the owner's manual: ConnectivityAcoustimass 10 system:Compatible with A/V receivers and amplifiers rated from 10 to 200 watts per channel, rated from 4 to 8 ohmsI would say yes.

I'm powering my car stereo (200 Watts max) and a small amplifier (30Watts RMS) driving a 10in sub in my room, and it's not cutting off. As long as the radio doesn't use more than 5-7 amps it should be good.

I don't have a 600 ohm HP. My HD800 is 300 ohms and the TEAC drives it more than fine while having plenty of volume left. Gluck.
