Yes, I notice that the CS600 headphone output comes directly from the output transformers as I understood it. Not sure what taps it is using.
@Julz
If you suspect a problem or incompatibility with the amp's headphone output, then you can try running the headphone straight off the speaker outputs. You will need an adapter cable to do this, but it will avoid any dedicated "headphone circuitry" that may be having a negative effect. Check forum postings to see if other Leben owners run their headphones directly off speaker outputs.
I didn't mean to chase you off the CS300 thread like that. It just gets really confusing in that thread when people start discussing the CS600 which is a totally different amp with different tubes.
I understand you are having a problem and just want help figuring it out.
I *just* sold my CS300XS a couple weeks ago. It drove the Alpha Prime fine. Leben taps the headphone off the speaker outputs, no "dedicated circuitry" beyond the resistors. Don't bother with speaker taps, you don't need them. There should be no incompatibility with the headphone output if everything is working as it should.
I suspect your CS600 has issues. Do you have different tubes you can try? Perhaps the power tubes are on their way out.
Does your Leben drive speakers correctly?

Hi Levlhed,
Thanks for your post and I understand for the threat diversion, no worries.
This is such a good news that you drove the AP fine with your CS300 and there is no incompatibility with Leben because I really love those headphone and would have been mad/sad to change.
I really think my issue comes from this particular unit for 2 reason (to be confirmed of course) :
1/ As said to Murray, I've tested a Sen HD650 no latter than 4 days ago on my Leben and it worked perfectly (idem for my Marshall Major)
2/ The sound of this AP unit is really weird with no bass / sub bass and a lot of crackle/saturation when I push the volume up as if the speakers inside have been damaged.
Otherwise I confirm the Leben drives my Proac just fine (right now playing Mozart...) and at pretty high volume when required.
FYI the Amp is 4 month old and I've just put a month ago a new quad of NOS reflector 6N3Ce tubes which are sait to be very good on the CS600 (cf. Jeff Day and other people).
I have sent a mail to MrSpeakers Europe and now wait for their feedback on the return process.
I'll keep you posted as soon as my unit has been changed.
Thanks all for your help.
Julien
Be aware that that HD650 are high impedance headphones while AP are low impedance headphones so that could be the reason for your problem
I understand that it might be the reason why the AP doesn't work on my system.
Neverthelss as the Leben CS600 has more power than the Leben CS300 and since Levlhed made the AP work properly on its CS300, I doubt it. I'm waiting for Leben's feedback on the Headphone output power.
Again, those cables are not needed at all with this amp. In fact they will probably damage his Leben. Please stop suggesting this to him.

Julian, please take this to PM with me or email with your reseller and let us sort this out. Working this issue in parallel in multiple places is not going to help us figure it out.
Hey everyone,
Have many people here had experience with MrSpeakers-Europe?
I am planning to order the Alpha Primes next month and it will be a lot cheaper ordering from Europe to the UK as no import fees.
MrSpeakers USA seems to provide the best customer service though, so I am tempted to order direct from the USA even if it will cost me more money.
Any opinions on ordering from Europe compared to importing would be greatly appreciated.
Make every day a fun day filled with music and friendship!

I've bought primes and mad dogs from Mrspeakers Europe, you should be ok.
That is not MrSpeakers Europe, it's a reseller. I just want to make it clear they're not part of our company.
