  Okay, Positivity. I have not read this entire thread. My CS300 with HD800 does not hum.
I live in Brooklyn, which is noisy, but late at night, tucked in behind Prospect Park, as I am here,
it is quiet.  

 
Great to hear that =) Do you know what version you have - what output resistors in the HP circuit?

The Lebel website still lists the US Distributor as Tone Imports 646-425-7800 jhalpern@mac.com

I found them a bit difficult to deal with since they wouldn't sell me one directly even though the closest dealer to me was 7 hours away in Cleveland. So I bought mine used.

I had a somewhat different experience.  I found them easy to deal with.  I live in the SF Bay Area and Tone Imports put me in contact with a dealer in LA.  Through the LA dealer I had the amp shipped to me directly from Japan.  It only took about 5 weeks from first contact to unboxing the amp.  As ever, YMMV.

Unboxing of Leben CS600 for those who are interested.

Edit: Does CS300 has similar packaging?

 

[msg1979]

Yes. Same box but smaller.
No box for power chord though

Does anyone know if a Leben cs300 will work with ecc82?
I know the gain will be like 70% so the volume must be set higher or?
But will auto bias and all the techs fit so I won't break anything?

The power chord is included right?

It is better to ask Leben just to be sure. Mr Yoshi Hontani email is y-hontani@musonpro.com. Please keep us posted when you find out.

The power chord was included in my cs300 and cs300x

If anyone wants to try a good solid state headphone amp, check out the Bakoon HPA-21.
 
I read on the Bakoon thread that Skylab didn't care for it, but it does keep up with the Leben.
 
It's the first headphone amp I've heard that didn't make me want to run back to the Leben.

Hi guys,
Been along time away!.. you know the usual story, loads of time on the forum when you have money in your pockets and less in between!?
 
So... please save me from 140 pages of reading!..
 
Am running the CS300 with LCD2's for a year plus now... awesome!!..
 
After running some iem's for a while the only thing I wonder is, if I am missing a little detail or mid to top end ?
 
I am of an age where I cannot hear anything over 15k ( probably lower ) and have a specific problem at 4K.... result of music in my eyes for 8+ hours a day for 6 years at work!... be warned!...
 
Anyway, I wondered if a little tube rolling might add something?
 
Can you point me in the right direction? / give me a few suggestions?
 
Thanks guys!
 
P.S no hum here!!

 

[Skylab]

What driver tubes are in it now?

If you have deep pockets, look for some Raytheon windmill getter 5751's

+1 windmill getters are superb possibly my favorite enjoyed them little more than my bugle boys

 

[MartinM]

Thanks guys ...
 
Not sure what I current have in there... the stock ones!...
 
At least this gives me a starting point for discussions... have email'd audiotubes to see what they can suggest, I have used them in the past and they seemed pretty good.
Any other good NOS suppliers?
 
One more stupid question, if you don't mind...
 
I assume the chances of getting a matched quad are remote so 2 matched pairs is what I need....
 
What if 1 tube blows.... do I get another matched pair?
 
Thanks guys... it's good to be back

 

[Skylab]

Reasonably well matched quads of 6BQ5 /EL84 tubes aren't that hard to come by, although not super cheap. As for what to do when one tube blows, that's just a matter of how much of a perfectionist you are. At least replacing the pair for one channel is a good idea.
