My favorite tube combination in my CS300SX is a pair of Sylvania 5751s (black plate, windmill getter) and a quad of Mullard EL84s.

So far my experience with Leben CS300 has been really awesome, both the speaker and headphone section of the amp are top notch. With my old Tannoy SRM 12X, the bass is tighter, much more deep, on all vocal songs the voice is more forward and it really make you feel the singer is right in front of you. I never heard such great bass from my tannoy since i parted with my old copland 402.

 

I have a pair of   Sylvania 5751 black plate, i wil try to put it in my leben tonight and see how it goes. So far i definitely become a fan of Leben, i'm thinking about getting their phonobox as well, are they any good compare to Ear 834P? Thanks

Hallo,
Does anybody have experience with Leben cs 300 ( any Model, but especially F) in combination with Abyss 1266?
Will it be strong enough to drive the Abyss?
Hoe about the HE6?
Many thanks for reply!
Tom

It is always better to have someone edit your work before you post it.

 

"Tubes in the Leben CS300XS: Golden Lion EL34 and RCA Wurlitzer Black 12AX7 (neither original)."

Your Leben has EL84 tubes, not EL34...whoops!

Leben as a general purpose amp

 

Not to divert the thread, but on another note. Has anyone tried running the Leben through an active preamplifier. I did this first some years ago with a symphonic line preamp and found that there was a lot more drive to the sound of the speakers (Proac tablette 86db ). Last week I have had a Xindak 3200 II with me and again I find that the sound is much more unstressesd and engaging through the speakers (Contrast audio AS 3), at lower as well ashigher volumes. 

 

Although I do listen through headphones (Beyer DT 880 and Senn 595), for the most part I listen to speakers. If any one has experience in running the leben through a preamp, I would like to hear from them. The volume pot in the Leben is a passive device, and as I understand it its function is that of attenuation and not amplification. An active preamp brings something to the table which the Leben benefits from, especially when driving the speakers. It could of course bring also about a change for the worse! Such as a light hum, which I can hear through my headphones but not the speakers.

 

Even though this is head-fi, since it is a Leben thread it would be nice to hear from those who also use the Leben for general listening on speakers. After three years of ownership i find that it is underpowered even for a speaker rated at 91 db or so. Recently I heard the leben on a 97 db rated speaker (Davis acoustics Monitor one, and although it was a bit honky, the dynamics were huge. the size and price of those speakers prevent me from going that way unfortunately

 

Thanks for any responses

Hmmm...I read somewhere else that Leben CS-300 sounds much better with the NVA P90 passive pre-amplifier.

 

I also use the ProAc Tablette Ref 8 Sig with my Leben 300x and find it has adequate power; though admittedly I listen to it in low volume as it is set-up for near field listening. I hardly ever go above 9 o clock with the volume knob.

Interesting: A passive sounding better.The Leben volume pot is already a passive attenuator I thought. 

 

Anyhow I have been listening to the active pre mentioned above and it does sound much fuller. If you have access to a decent pre do try it out.
