Hi guys, hi Shaan

Just to drop in a shortage of time I'm currently in. Very nice activity going on for a basic SSA, now even with DC offset control, congratulations Shaan. Did you maybe consider of using TL071 ie. single DIL8 opamp?

I'll go on with CSA testing as soon as possible and will report back.

Regards Andrej

Andrej, I think you need be congratulated. This thread is now about one year old and your enthusiasm is still outstanding. Very well done! I am curious to know besides the people that contribute here continually how many DIYer's has experimented SSA in some form or other.

I have... Numerus versions different outputs and housekeeping, now I have designed what is like an up scaled version of the hiraga, topology is almost the same, but current feedback is injected into the VAS, making the feedback path one stage shorter.

Hi

Yes, last week we had local Multimedia Show in Ljubljana and I was invited to bring something new, so I made fully switching monoblocks from Hypex NC400 + SMPS600 link here.

In a show room NC400 showed a big potential with its superb linear-neutral musical presentation along with extreme control, dynamic and power levels.

Tomorrow I will go to a studio where SSA is located and will bring NC400 monoblocks to compare to SSA. Quick listening report of a first impressions will follow.

Thank you Nico for your kind observations and comments.

Yes, well audio in general and building amps are my dear hobby so I invest all my spare time and energy to them.

I am also glad that other DIY-ers found something usable from my posts and I support them as much as I can. Will try to do the same in the future as long as there will be some interest.

Thanks again Nico
