They are different, the HD650 is a better headphone. It performs better technically, it gives you a bit more resolution and for sure soundstage. The HD600 has no soundstage. However, you lose a bit of that treble clarity on the HD650.
What are you driving that's single ended you need more than a Watt?
If you have more expensive headphones that need the power you can get balanced cable. I would go with Hart Audio, they have good cheap cables.
Can someone elaborate on why you can have an AMP that does 3W but tops out on volume really low.
Like can have 2 different amps that does 3Watts but have different current and voltage ratings?
Here is what cracked me up, I was on my other form where they are all about "everything has a sound man" they think more expensive = better sound. I think its partly true to a point.
So, they were like yea the "ESS chips back in the day had a glare to them, I didn't like them at all." LOL...
How do you figure out the VRMS on an AMP?
This is for the Susvara, to bring it to listening levels all you need is .5 watts, but the voltage and current need to be higher. How do you find what an amp is rated at?
While he seems like a nice guy and all, I could deal with his reviews being objective, but he turned around and started saying the Susvara shuts off his headphone amps, I was like what....? Like when he plays heavy bass music the AMP just shuts off becasue its drawing to much power, that is...
I am using the SMSL M400 with the SA-1 at the moment, volume is on 80, I think the m400 does 5.7V. I should try the RME again, what's this jumper bypass? That sounds interesting... I am using the Susvara's, same thing I supposes, still stupidly hard to power.
I can listen with them off the...
H-z is to change the output impedance of the headphone output from 1.4 to 10 I think it is. I don't see why you would want to do that unless it was to mess with the sound or to use 600 ohm headphones or something.
I have tested a number of headphones ranging from 60-300ohm, they all sound a lot...
