HI. Just bought D2K. Will be using them on pc. Sound card is xonar dx so i decided to buy a second hand receiver as cheaper than headphone dedicated amp/dac.
What would be better...?
Yamaha RX-V450 with 150mV/100[size=small]Ω[/size]
[size=small]or[/size]
[size=small]Yamaha RX-V371 with 100mV/470[/size][size=small]Ω[/size]
[size=small]or maby other sugestions??[/size]
[size=small]Im new in the audio world and sry about my english.[/size]
[size=small]Thanks.[/size]

Noone knows about ohms and wolts?

Impedance is resistance, measured in Ohms.
 
Receiver's headphone jacks usually have a high impedance (Ohms), and the Denon AH-D2000 is only 25-Ohms.
and you really want to use with the AH-D2000 a headphone output with a low impedance, like 3.125-Ohms or less.
You want the headphone impedance to be 8 times or more of the headphone output jack's impedance.
The O2 (Objective 2) portable headphone amplifier ($155) comes with a low impedance of under 1-Ohm.
The O2 can function like a normal AC powered desktop head amp.
 
The Fiio E11 portable headphone amplifier ($51) has an impedance of under 1-Ohm

Doing this will i keep an original sound from my sound card but amped?

The Xonar DX is a good sound card, not great at driving headphone.
So plugging any external headphone amplifier into the Xonar DX is a great combo.
