The Leben CS300XS Thread - Page 104

post #1546 of 2112

It's actually quite easy to change the resistors if you have soldering skills. Newer models have the 1Kohm or higher value resistor, Mine came with a 1,3Kohm resistor that is why it's under powered for my LCD. But when I changed it with a 270ohm resistor, Everything changes. biggrin.gif

 

My guess will be around the year 2005-2006 when they did the new reversion of the amp using the WBT binding post that's also when they changed the Headphone out resistors.

It is much later than that. I bought mine in 2011 and it clearly has the lower resister.

It is a bad design decision on their part.

I asked Leben about why the HD650 (103dB)  is humming on my Leben CS300XS, whilst my less sensitive Audeze (LCD-2rev.1/3 - 93db) and HiFiman HE500 (89dB) cans are not:

 

Here's the answer from Leben

There ya go...you can actually make them if you are willing to..

Mine was produced in the late 2010 and got the 1,3Kohm resisitor..soo i guess they just randomly install them?

That is very odd. Mine is a 120v model. Is yours?

Besides the different tube compliment, what are the other differences in specs?
post #1555 of 2112

I like the HD800 more than the LCD 2/3 anyway. :)

So, what's a good price to be looking for one of these for (used)?   I'm looking for the CS-300SX or the original CS-300.

post #1557 of 2112

The 300XS runs around 4k new...So I'd go by that.

So 4K for a used one? Seems a bit high, but if you think so. I was just wondering because all of the head-fi classifieds don't have pricing any more.
post #1559 of 2112

No no, they're NEW at 4k.

So like $2.8k - $3.5 used?  Does that sound about right?
