Very nice looking SSA, congratulations. Shaan you're good teacher, congratulations to you too.

Naf now you can go stereo.

Of course impressions will follow, yes?

Hi LC.

You are a God and an irreplaceable asset to diyAudio. Thanks for the light you shed over the community with the elegant duo, the SSA and the BIGBT.

Hi naf, me too await a review of the stereo impression.

I rechecked the offset again and it reads 11.5mV.

P.S. peeceebee with servo is almost done.

I found a PCB maker here named Nutech and hopefully will get a bunch of them soon. HOHO

Ooh! RED LEDs look HOT! COOL! Nice job naf!
Dear Shaan,
Kindly add two more pieces of PCB for me (from Hyderabad)

I opened an SSA thread in Hifivision, our local diy forum. Response is very positive, and just a few minutes ago I got a call from one of the interested guys and we talked about it for half an hour. AND he is going to build it, two of it!

Hey, I want to propose a simple test simple test and would like to know what it reveals. Turn off one channel so you are listening in mono. Sit with one ear pointing directly at the speaker and close your eyes. Tell us about the soundstage quality, detail and focus in this configuration.

Hi mas Nafiri,
congratulation
I'm waiting your good reports he...he...

Hi LC, Shaan & everybody here
I'm searching where is the all BJT version of this SSA, dont find it yet
So please help
maybe I will build a pair.
I'm also confuse which one is the best to make
if I follow my friend Naf, I don't have the lateral
I think it is just okay with all BJT version, I have lot of BJT already

Thanks for all

Hi John. I think the following place has what you want!

Have fun!

edit:- None of the configs is best. The one that suits your needs is the one for you...
