legato buffer.

[back]

i use a legato for without the buffer for a while.

comparing it with the buffalo 32s the bass is tighter for the 32s but at everything else i prered the legato.

i read somewhere that the output impedance at legato is 150 ohm but with the buffer is less than 1 ohm.

my amps input is 100k balanced.

if i add the buffer will i have tighter bass?

any other mod to make the bass a little tighter?

p.s. it`s the legato version 1

With 100k load you would not really get much difference at low frequencies.

What you are observing could be in part to the AC coupling of the Legato.

thanks russ.

i thought the same but i wonder if there will be a small difference or no difference at all.

i use it dc coupled since my amp have input caps and there is no need to have two caps at the signal path.

i wonder if the bigger output of 32s have something to do with it.

what kind of resistors would bring legato close to the 32s?

[Russ White]

Absolutely. The higher output swing could be what you notice there.

You should be able to use 200R I/V resistors, if you go much higher than that your going to need to change the CCS Resistors as well.

i would say 300r would be close to 3v rms.

i guess the ccs must be something like 660r?

[Russ White]

Yes, even 681R should be fine.
