With that view in mind - a little bit of research kept throwing up the name Aniket Das on our forum. Fortuitously he posted his recent build a few months ago and I was intrigued enough to contact him and eventually ordered his amp. (ss2150). It took a couple of months but it was finally shipped out (very professionally packed btw).
The unit I got is a standard 17" width but deep, and more importantly heavy. Ok heavy doesn't mean better sound, but right there - to me at-least is an indication of quality. I hooked it up to my 2nd system with a Topping pre 90 pre, and I was very impressed by what I heard. Impressed enough that - out of the box - cold, I heard the amp. for 2 hours straight playing back qobuz new jazz releases. For the past few days I continued listening and I am even more impressed. This amp. does mid range superbly, but does both frequency extremes very well, and particularly digs deep into the bass. Tonally it is very balanced and has a neutral presentation.
The icing on the cake is a gain switch on the back, one feature that I find indispensable to match to pre-amps, but sadly absent on 99% of power amps out there - at any price range. However the biggest surprise is the pricing - No I won't disclose it here - simply because I prefer you ask Aniket directly, but let me tell you it is the best bargain for a power amp. you are likely to find. For now I am thoroughly enjoying it, and more importantly - to me - I feel Aniket is a real asset to our hobby. Hopefully he does very well, and I am likely to be his repeat customer for some other upcoming projects I have in mind. Attached -some pics of the O&B SS2150 in action in my 2nd system.
