Signal indicator circuit tweaking

I have built the attached circuit into an existing 5 channel mixer project.
It monitors by way of 2 led’s the signal level present at the output of the mixer.
It monitors L&R outputs with two adding diodes at its input.
My question is. I would like to double its sensitivity instead of the first Led turning on at 2V, i would like to have it switch on at 1V of input, and the red led at 2,5V of input.
Which components should be changed? I was thinking change all diodes to Schottky perhaps?
Thanks in advance.

That is a lot of parts for a simple function, but last time I did something similar I used one op amp and almost as many discrete parts, but I added a peak hold and more... (that circuit is posted around here somewhere I shared it in recent years, BTW I used a bi-color LED). 

I would consider more than diode swaps but I'm afraid if I start giving advice I will have to finish it...  :

LM393 and a couple of pots seems to be very popular

Here is a thread from Waynes forum with several simple detecting strategies.

I think I recall other examples listed there but didn't find them quickly.
