Just wondering if anyone knows if these'll power anything like the DT 990's from Beyerdynamic at the 250 ohms mark? Have a few pairs of less taxing cans I plan on running off of this lil' beast but was just wondering if it's an all-rounder for anything that really requires a lot to drive, if anyone knows?
I have a C5 amp (no DAC) and it powers my DT 770 250 ohm cans great! I stack it with a Cayin i5 DAP and it sounds fantastic! I believe that the C5 amp and the C5 amp/DAC combo have the same power components.
Hope this helps.
Aw sweet, thanks for the help man - Definitely gonn' have to catch this drop!
Not the same last time I checked.
Amp only specs: Output Power: 800m W+800m W (32Ω)
Output Power: 300mW W+300mW (32Ω)
Wow. Big difference. Thanks. Sorry about that.
Ah, so will it realistically struggle to run anything driving at 250 ohms, do you think?
Ah alright, I've only managed to find the input impedance so far but thanks for the help dude!
From what I can gather it seems like it's output impedance is 32 Ohm -- Is this too high would you say? Sorry for the bother, fairly entry level knowledge of audio stuff here haha
Where did you find that spec? It is important to differentiate output impedance and voltage/current. Here is a link to determine headphone sensitivity and voltage current needs for a target decibel output.
The importance of a low enough output impedance of an amp is that frequency response fluctuates. If the output impedance is too high for the headphones the voltage delivered to the headphones will also change with frequency.
It is important that the amp will provide enough power to play your headsets to a reasonable loudness level with low distortion but the only way to get consistent performance is to use a low impedance amp.
I honestly just checked through the specs portion of the product page here on Massdrop and found:
"Rated output power: 300 mW + 300 mW (32-ohm load)"
Given I'm fairly lacking in knowledge around all of this I'm kinda' just guessing that, that is indeed the output impedance voltage you mentioned?
No it is not. That is the rated power for a given ohmage of an output device.
The output impedance is 32 milli Ohms(I read it on a forum from a Cayin representative).
I tested this AMP with Fostex T50RP MK3, AKG K7XX and B&O H6.
They all got plenty of power, even at low gain.
The H6(and most IEMs) would not get enough power if the AMP had 32 ohms output impedance.
I once plugged H6 into a SoundBlaster E1, which has 10ohms output impedance, and all I could hear was noise and almost no music. But the E1 powered K7XX just fine.
I'm new to this hobby and I was expecting to be surprised by this amp, but I could not tell the difference between odac+C5 and Pixel XL, other than louder volume. I wonder if Objective2 is better than C5.
