What's about EDGE Audio ?

Anybody?

Thanks.

Do you know something about the Edge's laser bias output stage, incorporating a 630 nm laser operating directly on the silicon substrate of the bias transistor?

How many years can works the laser?

Do you think there will be any reliabilities issues about
that original circuitry ?

Hi Fossda,
thanks for your answer.
I want to buy an EDGE NL 12 .
Some questions:
1) Do you know if are there any differences in technology
AND
in the sound reproduction between the NL 12 and the NL 12.1
or Nl 12.2 ?

2) Do you know the year of production of all those NL models?

3) Do you think is it a good idea to match the NL 12 with a tube preamplifier? ( i.e. Jadis, ASL Flora EX , CAT )

MMB.

Hi Bill,
the input impedance of the NL 12 is circa 34 Ohm. Voltage gain is 30 dB.
