LDR Active Preamp - does it exist?

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

"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 :)

CD/BluRay player is Oppo BDP-103. I dont know what are the output impedance nor voltage. I asked them the output voltage and impedance, but their answer was abit vague "designed to work with receiving equipment which is expecting an input impedance between 10K and 40K"

Amps are monoblocks Shuguang S845 MKII, which is 845 output tube.
