It's actually a little scary to me that the Leben could potentially sound even BETTER...



 

 

iamoneagain has Jap version 100v A-T ATH-DHA3000 with ATH-L3000. He plugged the amp right into US 120v wall, no fire or explosion YET. Here are a few members doing the same thing. Well, you could one day plug-in yours direct into wall for a few min to test out. Let us know the result.

I will do that one day when I see the AC drooping here to like 110V or so (mine is normally about 125V, on the high side).

Jack has a switch on the back of his amps to switch between 110v-220v. There's no 120v so there's a 10v difference there when used in a 120v household. And what happens when 220v is used in a 220v home--does that decrease the SQ from when the switch was set to 110v? Why can't every amp have this switch feature? It seems like a simple solution.

Shameless repost but I hope people didn't forget about me:



Does anyone here owns the CS300?  I know people are getting the XS model since it's on Price Japan but my issue is I'll be using it for headphones only and I honestly don't know if there will be a difference between the 300 and the 300XS headphone amp wise.

 

For those who use Grados (I own the RS-1i) why you think the Leben amps are less than perfect?  

 

Anyone?  (Wind blows).

 

:D

HyperDuel, I don't think you will be sorry to get the CS300 model.

 

I would have bought that model if it was available.

I don't think I would be sorry if I get the 300 one, but like everyone here has the upgrade model.  I just don't know if the better parts will make the headphone amp sound better. 

post #262 of 2094

Does anyone has a theory how a transformer-output amp, which, in theory, suitable only for low impedance headphone can sound very good on high impedance phone?  DIY experts, anyone?  I still don't get it.

 

 

In any case, I should get my Leben tonight to give it a shot.

Also I will say that I have imported plenty of Japanese electronics over the years and NEVER needed to use a step-down converter.   One of my old friends was an electrician and he told me houses and apartments do vary on voltage (he see some houses as low as 104v and high as 130v).  A small difference in voltage will not be deadly as plugging in a 110v product in a 220v outlet.  

 

If I get this (god willing if I have the cash) I will plug it in straight to the outlet.  

 


i've owned a standard CS300 for about a year and a half now, but have never heard an "X" version. Gu Sensei has owned both, and described the difference to me as an "audiophile upgrade." This makes sense to me, and indicates that the amount of difference you hear will probably depend on how seriously you listen to your gear, and how much faith you put into more spendy parts upgrades. i'm sure Mr. Sensei could elaborate further.

 

and for what it's worth, i have no issues using Grados with the Leben, other than the small range of usable steps i get with the volume control.

 

regarding the question of voltage, i would be very leery of running a 100V amp out of a 120V socket. as you say, voltages do vary and fluctuate. most appliances/electronics allow for tolerances within a small range, but anything above will harm and shorten the lifespan of your amp over time. at the very least, you should take measurements of your wall socket a few times over the course of a day to see what the values are, and how much they spike.

Hi.

 

I have the CS300, but have not heard the XS, and use it with my Grados.

 

With the CS300, my RS1 are as transparent as I've heard them (in my home) and the timbre is better than ever. This applies to my other headphones to.

 

What the amp doesn't do is smooth things out, no rolled of treble or adding much midbass to make the sound warmer/smoother. To my ears, the amp let the RS1 really show itself in all it's glory, but it does not help with it's small drawbacks, which are a bit rolled of deep bass and raised treble compared to other higher-end phones. I've always liked the RS1 with vocals, and they really are supreme with this amp. Good recordings sound very good, but recordings which the RS1 usually have problems with will probably still be a problem with the CS300. One would probably have to change headphones or change to a more coloured amp to help the RS1 with them.

 

I have not rolled tubes though so maybe other tube combinations could minimise the drawbacks of the RS1.

 

As for volume and RS1, I find it perfect. I've never had any problem at all to use the volume I wanted with no channel imbalance issues.

 

It's a very good amp, no doubt.

I'm looking at both tone imports and pricejapan for this.  Any feedback on those two sellers?

post #267 of 2094

Price Japan is a lot cheaper than going thru Tone Imports.

I know its cheaper, and thats pricejapan's major plus.  I'm wondering about differences in quality, service, etc.  Thanks.

post #269 of 2094

Price Japan is much cheaper, but you get the 100V version.

 

Tone imports will get you the 120V version (and presumably an easier way to get it fixed if there were a problem), but for about a 40% premium.

post #270 of 2094

I would presume if you go thru Price Japan and there's a problem with the amp I would believe you would have to send the unit to Japan to get it fixed.  

 

More things to think about honestly.
