Amp for AKG K240s 55 ohm???

post #1 of 14
Thread Starter 

Hey guys I'm kind of new to this site so I was wondering if you could help me out. I recently bought the AKG k240s 55ohms model two  months ago and I really enjoy it. However for some of the albums I heard distortions at the higher volumes. I usually listen to jazz and a little classical(mostly Beethoven's symphonies). So anyone know a good amp/dac under three hundred dollars? 

 

Thanks

Well, when I had those cans, they were driven relatively easily from whatever I had (iPod, all receivers, Asgard, laptops, etc). When I plugged them into the Asgard, they seemed to tighten up a bit in the bass. Otherwise, no major differences for me. You could take a look at the Asgard, but it's just an amplifier. You could also take a look at those new Magni and Modi amp/dac units from Schiit. I have no experience with those, though, so I can't speak for them first hand. Read around a bit, and I'm sure you'll dig something up.

Yeah I was thinking of getting the Magni/Modi combo, though for now I can only afford one. So anyone know anything about the two? and which of the two I should get first?

Theoretically, you don't need a lot of power for 55ohms headphones, so you may start with only dac, that . Obviuosly wait for a confirmation, you may need anyway some amp to connect you're headphone. 

 

If you're listening from a common laptop now, you'll see (hear) a huge improvement with this dac/amp combo i believe. A pity it's really difficult to get it here in italy.

Also to keep in mind, is that while they are 55 ohms, their sensitivity is 91dB/mW. So while their impedance is low, they aren't particularly sensitive. I always say that these cans are 'relatively' easy to drive as opposed to easy to drive. When I had them, I never had an issue driving them from any device, but regardless they do seem to like a bit of power.

So should I get the Magni first?

I just acquired the Hifiman EF2A headphone amp. It's a hybrid tube amp/DAC and is driving my AKG 271 mkII's. (55 ohm)
I am ripping CDs in lossless format and playing thru iTunes, using the USB input and also some mp3's and even pandora thru the RCA inputs.
I have been pleasantly surprised and am loving the sound. I realize I can tweak the sound a bit with different tubes, but for now my eardrums are happy! neju6e4e.jpg

Look for a deal in amazon. You can find it under $200 sometimes.

Yeah it seems like you can buy it for 169 on their website. I'm just worried if this is the best amp/dac under 200$. How does it compare to FiiO e17 or the Audioengine D1 Premium 24-Bit DAC?

Actually now I'm looking at the Magni/Modi combo, anyone have a opinion of this combo?

I have always preferred "wire with gain" solid state amps with my K24S-55.  I always found them more of a groovy-fun headphone than flat-analytic... closer to a Grado HF1 than AKG K701.

 

I have a mister-X built pimeta that I like with these cans, but my Larocco PPA is my go to amp for wire with gain.  These are older DIY builds and are harder to come by in 2013.  If you can find one on the used BST boards go for it.  I always liked the Gilmore lite for this kind of thing too... great sounding circuit that won't leave you broke.  Originating from the brains of one of the better head-fi designers.
