LDR Active Preamp - does it exist?

Nguyen787 Hi, 4v sensitivity for your amp means it needs 4 v in to get it to go to full level, that means when using a passive you need a source cdp or dac that gives out 4v or greater. It would be far better if the amp were changed to two 2v sensitivity. What is the name and model of this amp so I can check to see if it is possible.?

Cheers George

Also please give the source name and model as this may be configured to give out more.

"Better"...for use with a passive preamp.

Maybe use the Burson Buffer?

6db of gain, or about 2V. Not ideal, although it solves potential future impedance mismatch problems too.

I have three questions here regarding using of buffer:

1.) My understanding is buffer provide no gain, it is rather impedance mismatch correction device. Burson website does not indicate 6dB gain nor voltage gain. I sent them an email today to inquire about gain will let you know about that.

2.) Does Burson use LDR for volume control?

3.) What are the main differences between Burson Buffer and other buffer such as Dodd Audio.

You see, I like Goeorge's Lightspeed so much and my amp is not a good match due to low sensitivity (4V input). Another way is to add gain into my amp via mod, but that is beyond my skill level :)
