Congratulations, Kushanava! I had listened to the upgraded bass modules of the V3 Saadhanas sometime back and there was indeed a subtle improvement over the earlier V3 units.
I'd visited the Rethm Studio a couple of weeks back also, and Jacob George had repositioned the Saadhanas by pulling them further into the room. The improvement (I was quite surprised that the old position could actually be improved on) was remarkable, with a far sharper imaging, wider stage (obviously) and with the bass more towards the feel-it-but-not-hear-it character.

The Saadhanas seem to LOVE more space behind them. I'm sure there is a point in all rooms where the space behind the speaker becomes counterproductive, but I urge you to find that position in your room, because these speakers sound markedly better with just the right amount of space behind them.
The space to the side of the speakers (between the speakers and the wall), as Prem said, makes a fairly marked change in the character of the sound. I found this aspect of the placement the most difficult to get right in my room, because I found that the sound (and the sharpness of the imaging) changed even with very small changes in position (probably because the room is quite narrow, and probably because I'm a bit of a worrywart). You should experiment with this aspect of placement.
I have my Rethm Trishnas set up in a smallish dedicated room. The room is trapezoidal in shape, with the front wall (wall behind the Trishnas) shorter than the rear wall, and with the side walls slightly slanted. The front wall is about 10ft wide, and the rear wall is nearly 12ft wide. The room is about 18ft long.
The Trishnas are placed 5 ft from the wall behind them (distance between baffle and wall), and 1 ft ,10 inches from the walls to their sides (distance between centre of driver and wall). The speakers are placed with 5 ft and 8 inches between the centres of the each driver. My seat is 8 ft from the mid point of the two speakers. The bass modules are set at 12 o'clock at this placement.
This is how the placement of the Trishnas looks like at my place, from the seat (the camera was placed on the back of the chair):
I have fairly stable power at home, so I have nothing set up in the power conditioning dept. (The stabilizer you see in the pic is the aircon's)
I keep meaning to get some "v" cut wood blocks to raise the speaker cables, but I've not yet got around to doing that.
I use Nanotech MS #207 interconnects and Rethm Speaker cables. I can't recommend both enough. Both made substantial improvements in the system when they were introduced into it.
I'm quite content and very happy with the overall setup now, so I don't experiment any more with placement or other equipment. (No, I'm not getting lazy, heh heh).
