Hi Guys ,
for the past couple of months I have been working on a amp design and its finally complete. Man it was some hard work sweat and tears , but the final outcome has been very pleasant. The listening impressions have been phenomenal too , the lows are powerfull beyond comparison , while the mids are clear and very upfront , while the treble is ever-present and soothing on the ears.




thanks
Aniket Das

Nice build.

It is a very cool-looking amplifier.

The one obvious to me thing I do see, that will hold you back sound quality wise, is the type of speaker binding posts used. I would target them first, as a necessary parts upgrade.

Generally, you do not ever want to use speaker binding posts that have any sort of plastic parts on them. Plastic is a terrible terrible sonic degrade.

The most neutral and best sounding of speaker posts, that I am aware of, are the Cardas CCGR, and in your case, you would want to use their shorter length ones, used with a metal chassis' thickness.

Do not ever wildly over-tighten Cardas CCGRs with a wrench and high leverage, as you can strip their threads. Apply human feel and human discretion.

Have fun.

Nope there is a massive 1200W toroid inside that box
Congratulations.
Speaker out terminals Horizontally drilled would have been little better than vertical(+/-) if using direct speaker wires. With bana plugs no issue.

Hi Guys ,
for the past couple of months I have been working on a amp design and its finally complete. Man it was some hard work sweat and tears , but the final outcome has been very pleasant. The listening impressions have been phenomenal too , the lows are powerfull beyond comparison , while the mids are clear and very upfront , while the treble is ever-present and soothing on the ears.




thanks
