The Astell and Kern AK240 Impressions Thread - Page 19

post #271 of 1415

I'm currently listening to my AK240 through my simple little bedroom system. Even here, the 240 reveals how great a source component it is.

 

The 240 is warming up a bit with over 100 hours on it, but I hope it improves even more. I find the upper mids to be a bit forward with a fine grain structure ... looking for more liquidity.

 

Somebody should make a dedicated power supply with a stiff output. I can't help thinking the dynamics on the 240 would improve greatly ... as well as the liquidity.

 

The 240, though, has reawakened my joy of listening to music, it's that good. :wink_face:

I've only been listening a few hours now, on the IE-800, now there's a match made in heaven, great soundstage , tight bass, very detailed. Very nice clarity. Sure wish they were balanced. I may make the leap, to some ciem's. I've been reading tons of reviews. I am kinda pissed about my HD-800's in balanced, just not being loud enough.

 

oh, you wicked man ...  :D

I can't post any pictures because when I click the attachment icon, I get a dialog box that says I'm not authorized. I know I can go search for the reason why, but does anyone know?

 

Off for a hike in the mountains with my new toy ...  :D

Based on my test on AK240 vs Hugo at Jaben Singapore, AK240 single-ended output can drive the 300-Ohm Sennheiser HD800 sonically but lacks the power to satisfy the volume/body of the music to an optimal level. However, AK240 synergizes really well with the 25-Ohm Fostex TH900. I heard the same exact volume/body directly from AK240 SE and from the Hugo's 3.5mm out. If we just compare their specifications on paper, LCD-XC actually has slightly lower impedance than TH900, but TH900 works well and not the LCD-XC. The 45-Ohm LCD-3 and the 22-Ohm LCD-XC are both planar magnetic which are very sensitive to the power of the amp compared to normal dynamic driver headphones and probably pose an challenge to AK240's single-ended output. Maybe the balanced out can help to boost the power output so at least we can see a better SQ from the Audeze cans.

 

By the way when I tested AK240 -> TH900, my ideal volume level was around 45 - 55 and it sounded about the same loudness as when I listen on my AK240 -> 1plus2 IEM at the same volume level. Pushing it up to 65 - 70 for TH900 is mad loud and will probably kill my ears, so I guess it is obvious LCD-XC needs a lot more power to drive even though Audeze marketed it at a lower impedance of 22-Ohm than TH900.

Orthos need more power than dynamic driver headphones

 This is not good news for the AlphaDOG, because I believe I read that the  AlphaDOG need more power than the new LCD X & XC !  is it correct ?

if just driving via an amp-less AK240, I barely gotten my LCD2 going and needs to run the volume at around 65-70. when switched over to AD, there isn't enough grunt to do justice to the AD even at max level of 75.

just my experience.

thanks... very valuable info for me.  

 

So... for my "totally non leaking headphone", Out the ALPHA, In the SigPRO ;-)   (unless someone has another suggestion ?? )

post #279 of 1415
Yeah right, this totally sucks..I'm so let down, that I can't drive my HD-800 loud enough. I just hooked it up to my Sager Laptop, ran the AK-240 in Dac mode, with the 1/4 connection into a Grado adapter , using the unbalanced connection. So I start Borderlands 2, video game, the volume is maxed out, the sound level is just about where I normally keep it, but can't go any higher even if I wanted to. Now what? U guys got any ideas on getting the power up on this baby? I love the 240 sound wise, I'm just bummed..

Go balanced.

Or just use AlphaDog on a different DAP like the HM-901 with the amp card.

Add an external amp to the AK240?
post #282 of 1415
Yes, but what kind of portable amp? I don't suppose there are to many guys running amps on the AK-240 already . ALO, has some nice portable ones. Guess it's back to the drawing board of reviews. Thanks for the help.
post #283 of 1415
IMO any amp that can drive your HD800 to a decent level and stay true to neutrality to benefit from AK240's DAC is good enough. You don't really need the amp to be portable since HD800 isn't really meant to be a portable cans. It shines only when used with desktop rig and using it with anything less than that will definitely curtail its prowess.

Suggest an SR71B

Its a small balanced amp. Has both single ended and balanced inputs and outputs

I've got a Nuforce icon HDP , and a fiio E-17 , never got to excited about the icon, seemed like I was always missing something . I do all my listening while on the road, so all my power comes from batteries& a pure sine wave inverter. So that's why I lean towards portable, or something that doesn't draw a ton of power. I've always heard great thing about Ray And his amps.
